PRODUCT DESCRIPTION
SST's ATA Flash Disk Controller is the heart of a highperformance, flash media-based data storage system. The ATA Flash Disk Controller recognizes the control, address, and data signals on the ATA/IDE bus and translates them into memory accesses to the standard NANDtype flash media. The SST55LD019M device supports Multi-Level Cell (MLC) and high density Single-Level Cell (SLC) flash media. This technology suits solid state mass storage applications offering new, expanded functionality while enabling smaller, lighter designs with lower power consumption. The ATA/IDE interface is widely used in such products as portable and desktop computers, digital cameras, music players, handheld data collection scanners, PDAs, handy terminals, personal communicators, audio recorders, monitoring devices, and set-top boxes. SST's ATA Flash Disk Controller supports standard ATA/IDE protocol with up to PIO Mode-4 and Multi-word DMA Mode-2 interface.

Utilizing SST's proprietary SuperFlash memory technology, the ATA Flash Disk Controller is factory pre-programmed with an embedded flash file system which, upon initial Power-on, recognizes the attached flash media devices, sets up a bad block table, executes all necessary handshaking routines for flash media support, and, finally, performs the low-level format. This process typically takes about 3 sec + 0.5 sec/GByte of drive capacity, allowing a 2 GByte flash drive to be fully initialized in about 4 seconds. This technology enables a very fast, completely seamless integration of flash drives into an embedded design. For added manufacturing flexibility, system debug, re-initialization, and user customization can be accomplished either through the ATA/IDE interface, for ATA Disk Module or flash drive products, or through the Serial Communication Interface (SCI), for fully embedded ATA Flash Disk Controller designs.

ATA Flash Disk Controller SST55LD019M
Advance Information
1.0 GENERAL DESCRIPTION
The ATA Flash Disk Controller contains a microcontroller and embedded flash file system integrated in TQFP and TFBGA packages. Refer to Figure 2-1 for the ATA Flash Disk Controller block diagram. The controller interfaces with the host system allowing data to be written to and read from the flash media. 1.1.5 Embedded Flash File System The embedded flash file system is an integral part of the ATA Flash Disk Controller. It contains MCU firmware that performs the following tasks: 1. Translates host side signals into flash media writes and reads. 2. Provides dynamic flash media wear leveling to spread the flash writes across all unused memory address space to increase the longevity of flash media. 3. Keeps track of data file structures. 1.1.6 Error Correction Code (ECC) 1.1.1 Microcontroller Unit (MCU) The MCU translates ATA/IDE commands into data and control signals required for flash media operation. 1.1.2 Internal Direct Memory Access (DMA) The ATA Flash Disk Controller uses internal DMA allowing instant data transfer from buffer to flash media. This implementation eliminates microcontroller overhead associated with the traditional, firmware-based approach, thereby increasing the data transfer rate. 1.1.3 Power Management Unit (PMU) The power management unit controls the power consumption of the ATA Flash Disk Controller. The PMU dramatically reduces the power consumption of the ATA Flash Disk Controller by putting the part of the circuitry that is not in operation into sleep mode. 1.1.4 SRAM Buffer A key contributor to the ATA Flash Disk Controller performance is an SRAM buffer. The buffer optimizes the host's data transfer to and from the flash media. The ATA Flash Disk Controller utilizes 72-bit ReedSolomon Error Detection Code (EDC) and Error Correction Code (ECC), which provides the following error immunity for each 512-byte block of data: 1. Corrects up to three random 12-bit symbol errors. 2. Corrects single bursts up to 25 bits. 3. Detects single bursts up to 61 bits and double bursts up to 15 bits. 4. Detects up to six random 12-bit symbol errors. 1.1.7 Serial Communication Interface (SCI) The Serial Communication Interface (SCI) is designed to enable the user to restart the self-initialization process and to customize the drive identification information. 1.1.8 Multi-tasking Interface The multi-tasking interface enables fast and sustained write performance by allowing concurrent Read, Program, and Erase operations to multiple flash media devices. This interface optimizes the performance of Multi-Level Cell (MLC) and high-density Single-Level Cell (SLC) flash media.
1.1 Performance-optimized ATA Flash Disk Controller
The heart of the flash drive is the ATA Flash Disk Controller which translates standard ATA signals into flash media data and control signals. The following components contribute to the ATA Flash Disk Controller's operation.

Advance Information
5.0 MANUFACTURING SUPPORT
The ATA Flash Disk controller firmware contains a list of supported standard NAND flash media devices. Upon initial Poweron, the controller scans all connected flash media devices and reads their device ID. If the device ID matches the listed flash media devices in the ATA Flash Disk controller, the controller performs drive recognition based on the algorithm provided by the flash media suppliers, including setting up the bad block table, executing all the necessary handshaking routines for flash media support, and, finally, performing the low-level format. For Power-up timing specifications, please refer to Table 11-4. Please contact SST for the most current list of supported NAND Flash media devices. In the event that the NAND flash media device ID is not recognized by the ATA Flash Disk controller, the user has an option of adding this device to the controller device table through the manufacturing interface provided by SST. Please contact SST for the ATA Flash Disk controller manufacturing interface software. If the drive initialization fails, and a visual inspection is unable to determine the problem, the SST55LD019M ATA Flash Disk controller provides a comprehensive interface for manufacturing flow debug. This interface not only allows debug of the failure and manual reset of the initialization process, but also allows customization of user definable options.
5.1 ATA/IDE Interface
The ATA Flash Disk controller interface can be used for manufacturing support. SST provides an example of a DOS-based solution (an executable routine downloadable from SST's web site) for manufacturing debug and rework.
5.2 Serial Communication Interface (SCI)
For additional manufacturing flexibility, the SCI bus can be used for manufacturing error reporting. The SCI consists of 3 active signals: SCIDOUT, SCIDIN, and SCICLK.
6.0 EXTERNAL CLOCK INTERFACE
The external clock interface allows ATA Flash Disk controller operation from an external clock source generated by an RC circuit. Do not use a free running clock as input to the EXTCLKIN pin; an RC circuit must be used. Contact SST for reference circuit and recommended external clock settings. While the controller has an internal clock source, the external clock source allows slowing of the system clock operation to limit the peak current and overcome additional bus loading. The external clock interface consists of three signals: INTCLKEN, EXTCLKIN, and EXTCLKOUT. The INTCLKEN pin selects between external and internal clock sources for the ATA Flash Disk controller. If this pin is pulled high before device Power-on, then the internal clock source is selected; otherwise, the external clock source is selected. The EXTCLKIN and EXTCLKOUT signals are the input and output clock signals, respectively.

7.0 CONFIGURABLE WRITE PROTECT/POWER-DOWN MODES
The WP_PD# pin can be used for either Write Protect mode or Power-down mode, but only one mode is active at any time. Either mode can be selected through the host command, Set-WP_PD#-Mode, explained in Section 10.2.1.20. Once the mode is set with this command, the device will stay in the configured mode until the next time this command is issued. Power-off or reset will not change the configured mode.
7.1 Write Protect Mode
When the device is configured in the Write Protect mode, the WP_PD# pin offers extended data protection. This feature can be either selected through a jumper or host logic to protect the stored data from inadvertent system writes or erases, and viruses. The Write Protect feature protects the full address space of the data stored on the flash media. In the Write Protect mode, the WP_PD# pin should be asserted prior to issuing the destructive commands: Erase-Sector, Format-Track, Write-DMA, Write-Long-Sector, Write-Multiple, Write-Multiple-without-Erase, Write-Sector(s), Write-Sectorwithout-Erase, or Write-Verify. This will force the ATA Flash Disk Controller to reject any destructive commands from the ATA interface. All destructive commands will return 51H in the Status register and 04H in the Error register signifying an invalid command. All non-destructive commands will be executed normally.
7.2 Power-down Mode
When the device is configured in the Power-down mode, if the WP_PD# pin is asserted during a command, the ATA disk controller completes the current command and returns to the standby mode immediately to save power. Afterwards, the device will not accept any other commands. Only a Power-on Reset (POR) or hardware reset will bring the device to normal operation with the WP_PD# pin de-asserted.

10.1.2 ATA Flash Disk Controller Registers The following section describes the hardware registers used by the host software to issue commands to the ATA Flash Disk Controller. These registers are often collectively referred to as the Task File registers. The registers are only selectable through CS3FX#, CS1FX#, and A2-A0 signals. 10.1.2.1 Data Register (Read/Write) This 16-bit register is used to transfer data blocks between the device data buffer and the host. It is also the register through which sector information is transferred on a Format-Track command. Data transfer can be performed in PIO mode. 10.1.2.2 Error Register (Read Only) This register contains additional information about the source of an error when an error is indicated in bit 0 of the Status register. The bits are defined as follows:
D7 BBK D6 UNC D5 0 D4 IDNF D3 0 D2 ABRT D1 0 D0 AMNF Reset Value 0000 0000b
Symbol BBK UNC IDNF ABRT
Function This bit is set when a Bad Block is detected. This bit is set when an Uncorrectable Error is encountered. The requested sector ID is in error or cannot be found. This bit is set if the command has been aborted because of an ATA Flash Disk Controller status condition: (Not Ready, Write Fault, etc.) or when an invalid command has been issued. It is required that the host retry any command that ends with an error condition. This bit is set in case of a general error.

Symbol BUSY
Function The busy bit is set when the ATA Flash Disk Controller has access to the command buffer and registers and the host is locked out from accessing the Command register and buffer. No other bits in this register are valid when this bit is set to a 1. RDY indicates whether the device is capable of performing ATA Flash Disk Controller operations. This bit is cleared at power up and remains cleared until the ATA Flash Disk Controller is ready to accept a command. This bit, if set, indicates a write fault has occurred. This bit is set when the ATA Flash Disk Controller is ready. The Data-Request bit is set when the ATA Flash Disk Controller requires that information be transferred either to or from the host through the Data register. This bit is set when a correctable data error has been encountered and the data has been corrected. This condition does not terminate a multi-sector Read operation. This bit is set when the previous command has ended in some type of error. The bits in the Error register contain additional information describing the error. It is required that the host retry any media access command (such as Read-Sector and Write-Sector) that ends with an error condition.

10.2 ATA Flash Disk Controller Command Description
This section defines the software requirements and the format of the commands the host sends to the ATA Flash Disk Controller. Commands are issued to the ATA Flash Disk Controller by loading the required registers in the command block with the supplied parameters, and then writing the command code to the Command register. The manner in which a command is accepted varies. There are three classes (see Table 10-2) of command acceptance, all dependent on the host not issuing commands unless the ATA Flash Disk Controller is not busy (BSY=0). 10.2.1 ATA Flash Disk Controller Command Set Table 10-2 summarizes the ATA Flash Disk Controller command set with the paragraphs that follow describing the individual commands and the task file for each.

This field defines, in nanoseconds, the minimum cycle time per word during a single sector host transfer while performing a multiple sector READ DMA or WRITE DMA command for any location on the media under nominal conditions. If a host runs at a faster cycle rate by operating at a cycle time of less than this value, the ATA Flash Disk Controller may negate DMARQ for flow control. The rate at which DMARQ is negated could result in reduced throughput despite the faster cycle rate. Transfer at this rate does not ensure that flow control will not be used, but implies that higher performance may result. SST's ATA Flash Disk Controller supports up to Multi-word DMA Mode-2, so this field is set to 120 ns. 10.2.1.5.24 Word 67: Minimum PIO Transfer Cycle Time Without Flow Control The ATA Flash Disk Controller's minimum cycle time is 120 ns. 10.2.1.5.25 Word 68: Minimum PIO Transfer Cycle Time With IORDY The ATA Flash Disk Controller's minimum cycle time is 120 ns, e.g., PIO Mode-4. 10.2.1.5.26 Word 80: Major Version Number If not 0000H or FFFFH, the device claims compliance with the major version(s) as indicated by bits (6:1) being set to one.

This command executes in a similar manner to the Read-Sector(s) command except for the following: - the host initializes the DMA channel prior to issuing the command; - data transfers are qualified by DMARQ and are performed by the DMA channel; - the ATA Flash Disk Controller issues only one interrupt per command to indicate that data transfer has terminated and status is available. During the DMA transfer phase of a Read-DMA command, the ATA Flash Disk Controller will provide the status of the BSY bit or the DRQ bit until the command is completed. 10.2.1.12 Read-Multiple - C4H

Note: The current revision of the ATA Flash Disk Controller can support up to a block count of 1 as indicated in the Identify-Drive Command information.
The Read-Multiple command is similar to the Read-Sector(s) command. Interrupts are not generated on every sector, but on the transfer of a block which contains the number of sectors defined by a Set Multiple command. Command execution is identical to the Read-Sectors operation except that the number of sectors defined by a Set Multiple command are transferred without intervening interrupts. DRQ qualification of the transfer is required only at the start of the data block, not on each sector. The block count of sectors to be transferred without intervening interrupts is programmed by the SetMultiple-Mode command, which must be executed prior to the Read-Multiple command. When the Read-Multiple command is issued, the Sector Count register contains the number of sectors (not the number of blocks or the block count) requested. If the number of requested sectors is not evenly divisible by the block count, as many full blocks as possible are transferred, followed by a final, partial block transfer. The partial block transfer is for n sectors, where n = remainder (sector count/block count). If the Read-Multiple command is attempted before the Set-Multiple-Mode command has been executed or when Read-Multiple commands are disabled, the Read-Multiple operation is rejected with an

Disk errors encountered during Read-Multiple commands are posted at the beginning of the block or partial block transfer, but DRQ is still set and the data transfer will take place as it normally would, including transfer of corrupted data, if any. Interrupts are generated when DRQ is set at the beginning of each block or partial block. The error reporting is the same as that on a Read-Sector(s) command. This command reads from 1 to 256 sectors as specified in the Sector Count register. A sector count of 0 requests 256 sectors. The transfer begins at the sector specified in the Sector Number register. At command completion, the Command Block registers contain the cylinder, head and sector number of the last sector read. If an error occurs, the read terminates at the sector where the error occurred. The Command Block registers contain the cylinder, head and sector number of the sector where the error occurred. The flawed data is pending in the sector buffer. Subsequent blocks or partial blocks are transferred only if the error was a correctable data error. All other errors cause the command to stop after transfer of the block which contained the error. 10.2.1.13 Read-Sector(s) - 20H or 21H

This command reads from 1 to 256 sectors as specified in the Sector Count register. A sector count of 0 requests 256 sectors. The transfer begins at the sector specified in the Sector Number register. When this command is issued and after each sector of data (except the last one) has been read by the host, the ATA Flash Disk Controller sets BSY, puts the sector of data in the buffer, sets DRQ, clears BSY, and generates an interrupt. The host then reads the 512 Bytes of data from the buffer. At command completion, the Command Block registers contain the cylinder, head and sector number of the last sector read. If an error occurs, the read terminates at the sector where the error occurred. The Command Block registers contain the cylinder, head, and sector number of the sector where the error occurred. The flawed data is pending in the sector buffer.

This command is identical to the Read-Sectors command, except that DRQ is never set and no data is transferred to the host. When the command is accepted, the ATA Flash Disk Controller sets BSY. When the requested sectors have been verified, the ATA Flash Disk Controller clears BSY and generates an interrupt. Upon command completion, the Command Block registers contain the cylinder, head, and sector number of the last sector verified. If an error occurs, the verify terminates at the sector where the error occurs. The Command Block registers contain the cylinder, head and sector number of the sector where the error occurred.

Advance Information Features 01H and 81H are used to enable and clear 8-bit data transfer mode. If the 01H feature command is issued all data transfers will occur on the low order D7-D0 data bus and the IOCS16# signal will not be asserted for data register accesses. Features 02H and 82H allow the host to enable or disable write cache in the ATA Flash Disk Controllers that implement write cache. When the subcommand Disable-Write-Cache is issued, the ATA Flash Disk Controller should initiate the sequence to flush cache to non-volatile memory before command completion. Feature 03H allows the host to select the transfer mode by specifying a value in the Sector Count register. The upper 5 bits define the type of transfer and the low order 3 bits encode the mode value. One PIO mode is selected at all times. The host may change the selected modes by the Set-Features command. Features 66H and CCH can be used to enable and disable whether the Power-on Reset (POR) Defaults will be set when a software reset occurs. TABLE10-6:Transfer Mode Values

This command enables the ATA Flash Disk Controller to perform Read and Write-Multiple operations and establishes the block count for these commands. The Sector Count register is loaded with the number of sectors per block. Upon receipt of the command, the ATA Flash Disk Controller sets BSY to 1 and checks the Sector Count register. If the Sector Count register contains a valid value (see Section 10.2.1.5.12 for details) and the block count is supported, the value is loaded for all subsequent Read-Multiple and Write-Multiple commands and execution of those commands is enabled. If a block count is not supported, an Aborted Command error is posted, and Read-Multiple and Write-Multiple commands are disabled. If the Sector Count register contains 0 when the command is issued, Read and Write-Multiple commands are disabled. At power on, or after a hardware or (unless disabled by a Set Feature command) software reset, the default mode is Read and Write-Multiple disabled.

99H or E6H
This command causes the ATA Flash Disk Controller to set BSY, enter the Sleep mode, clear BSY and generate an interrupt. Recovery from sleep mode is accomplished by simply issuing another command (a reset is permitted but not required). Sleep mode is also entered when internal timers expire so the host does not need to issue this command except when it wishes to enter Sleep mode immediately. The default value for the timer is 15 milliseconds. 10.2.1.20 Set-WP_PD#-Mode - 8BH

This command configures the WP_PD# pin for either the Write Protect mode or the Power-down mode. When the host sends this command to the device with the value AAH in the feature register, the WP_PD# pin is configured for the Write Protect mode described in Section 7.1. The Write Protect mode is the factory default setting. When the host sends this command to the device with the value 55H in the feature register, WP_PD# is configured for the Power-down mode. All values in the C/D/H register, the Cylinder Low register, the Cylinder High register, the Sector Number register, the Sector Count register, and the Feature register need to match the values shown above, otherwise, the command will be treated as an invalid command. Once the mode is set with this command, the device will stay in the configured mode until the next time this command is issued. Power-off or reset will not change the configured mode.

This command executes in a similar manner to Write-Sector(s) except for the following: - the host initializes the DMA channel prior to issuing the command; - data transfers are qualified by DMARQ and are performed by the DMA channel; - the ATA Flash Disk Controller issues only one interrupt per command to indicate that data transfer has terminated and status is available. During the execution of a WRITE DMA command, the ATA Flash Disk Controller will provide status of the BSY bit or the DRQ bit until the command is completed. 10.2.1.25 Write-Multiple - C5H

Note: The current revision of the ATA Flash Disk Controller can support up to a block count of 1 as indicated in the Identify-Drive Command information.
This command is similar to the Write-Sectors command. The ATA Flash Disk Controller sets BSY within 400 ns of accepting the command. Interrupts are not presented on each sector but on the transfer of a block which contains the number of sectors defined by Set Multiple. Command execution is identical to the Write-Sectors operation except that the number of sectors defined by the Set Multiple command is transferred without intervening interrupts. DRQ qualification of the transfer is required only at the start of the data block, not on each sector. The block count of sectors to be transferred without intervening interrupts is programmed by the SetMultiple-Mode command, which must be executed prior to the Write-Multiple command. When the Write-Multiple command is issued, the Sector Count register contains the number of sectors (not the number of blocks or the block count) requested. If the number of requested sectors is not evenly divisible by the sector/block, as many full blocks as possible are transferred, followed by a final, partial block transfer. The partial block transfer is for n sectors, where: n = remainder (sector count/block). If the Write-Multiple command is attempted before the Set-Multiple-Mode command has been executed or when Write-Multiple commands are disabled, the Write-Multiple operation will be rejected with an aborted command error.

Advance Information Errors encountered during Write-Multiple commands are posted after the attempted writes of the block or partial block transferred. The Write command ends with the sector in error, even if it is in the middle of a block. Subsequent blocks are not transferred in the event of an error. Interrupts are generated when DRQ is set at the beginning of each block or partial block. The Command Block registers contain the cylinder, head and sector number of the sector where the error occurred and the Sector Count register contains the residual number of sectors that need to be transferred for successful completion of the command e.g. each block has 4 sectors, a request for 8 sectors is issued and an error occurs on the third sector. The Sector Count register contains 6 and the address is that of the third sector. 10.2.1.26 Write-Sector(s) - 30H or 31H
Bit -> Command (7) C/D/H (6) Cyl High (5) Cyl Low (4) Sec Num (3) Sec Cnt (2) Feature (1) 1 LBA 1 7 6 5 4 Drive Cylinder High (LBA 23-16) Cylinder Low (LBA 15-8) Sector Number (LBA 7-0) Sector Count X 3 2 1 0
30H or 31H Head (LBA 27-24)
This command writes from 1 to 256 sectors as specified in the Sector Count register. A sector count of zero requests 256 sectors. The transfer begins at the sector specified in the Sector Number register. When this command is accepted, the ATA Flash Disk Controller sets BSY, then sets DRQ and clears BSY, then waits for the host to fill the sector buffer with the data to be written. No interrupt is generated to start the first host transfer operation. No data should be transferred by the host until BSY has been cleared by the host. For multiple sectors, after the first sector of data is in the buffer, BSY will be set and DRQ will be cleared. After the next buffer is ready for data, BSY is cleared, DRQ is set and an interrupt is generated. When the final sector of data is transferred, BSY is set and DRQ is cleared. It will remain in this state until the command is completed at which time BSY is cleared and an interrupt is generated. If an error occurs during a write of more than one sector, writing terminates at the sector where the error occurs. The Command Block registers contain the cylinder, head and sector number of the sector where the error occurred. The host may then read the command block to determine what error has occurred, and on which sector. 10.2.1.27 Write-Verify - 3CH

12.0 APPENDIX 12.1 Differences between SST's ATA Flash Disk Controller and ATA/ATAPI-5 Specifications
12.1.1 Idle Timer The Idle timer uses an incremental value of 5 ms, rather than the 5 sec minimum increment value specified in ATA specifications. 12.1.2 Recovery from Sleep Mode For ATA Flash Disk Controller devices, recovery from sleep mode is accomplished by simply issuing another command to the device. A hardware or software reset is not required.
