The memory array organization may be divided into either bytes (x8) or words (x16) which may be selected by a signal applied on Organization Select (ORG). The bit, byte and word sizes of the memories are as shown in Table 3..
A Read Data from Memory (READ) instruction loads the address of the first byte or word to be read in an internal address register. The data at this address is then clocked out serially. The address register is automatically incremented after the data is output and, if Chip Select Input (S) is held High, the M93Cx6 can output a sequential stream of data bytes or words. In this way, the memory can be read as a data stream from eight to 16384 bits long (in the case of the M93C86), or continuously (the address counter automatically rolls over to 00h when the highest address is reached). Programming is internally self-timed (the external clock signal on Serial Clock (C) may be stopped or left running after the start of a Write cycle) and does not require an Erase cycle prior to the Write instruction. The Write instruction writes 8 or 16 bits at a time into one of the byte or word locations of the M93Cx6. After the start of the programming cycle, a Busy/Ready signal is available on Serial Data Output (Q) when Chip Select Input (S) is driven High.

MEMORY ORGANIZATION
The M93Cx6 memory is organized either as bytes (x8) or as words (x16). If Organization Select (ORG) is left unconnected (or connected to V CC) the x16 organization is selected; when Organization Select (ORG) is connected to Ground (VSS) the x8 organization is selected. When the M93Cx6 is in stand-by mode, Organization Select (ORG) should be set either to V SS or VCC for minimum power consumption. Any voltage between VSS and V CC applied to Organization Select (ORG) may increase the stand-by current.

POWER-ON DATA PROTECTION
To prevent data corruption and inadvertent write operations during power-up, a Power-On Reset (POR) circuit resets all internal programming circuitry, and sets the device in the Write Disable mode. - At Power-up and Power-down, the device must not be selected (that is, Chip Select Input (S) must be driven Low) until the supply voltage reaches the operating value VCC specified in Table 9. to Table 11.. - When VCC reaches its valid level, the device is properly reset (in the Write Disable mode) and is ready to decode and execute incoming instructions. For the M93Cx6 devices (5V range) the POR threshold voltage is around 3V. For the M93Cx6W (3V range) and M93Cx6-R (2V range) the POR threshold voltage is around 1.5V.
Note: 1. See PACKAGE MECHANICAL section for package dimensions, and how to identify pin-1. 2. DU = Don't Use.
The DU (Don't Use) pin does not contribute to the normal operation of the device. It is reserved for use by STMicroelectronics during test sequences. The pin may be left unconnected or may be connected to VCC or V SS. Direct connection of DU to VSS is recommended for the lowest stand-by power consumption.

INSTRUCTIONS
The instruction set of the M93Cx6 devices contains seven instructions, as summarized in Table 5. to Table 7.. Each instruction consists of the following parts, as shown in Figure 4.: s Each instruction is preceded by a rising edge on Chip Select Input (S) with Serial Clock (C) being held Low. s A start bit, which is the first `1' read on Serial Data Input (D) during the rising edge of Serial Clock (C). s Two op-code bits, read on Serial Data Input (D) during the rising edge of Serial Clock (C). (Some instructions also use the first two bits of the address to define the op-code). Table 5. Instruction Set for the M93C46

The address bits of the byte or word that is to be accessed. For the M93C46, the address is made up of 6 bits for the x16 organization or 7 bits for the x8 organization (see Table 5.). For the M93C56 and M93C66, the address is made up of 8 bits for the x16 organization or 9 bits for the x8 organization (see Table 6.). For the M93C76 and M93C86, the address is made up of 10 bits for the x16 organization or 11 bits for the x8 organization (see Table 7.). The M93Cx6 devices are fabricated in CMOS technology and are therefore able to run as slow as 0 Hz (static input signals) or as fast as the maximum ratings specified in Table 20. to Table 23..

Read The Read Data from Memory (READ) instruction outputs data on Serial Data Output (Q). When the instruction is received, the op-code and address are decoded, and the data from the memory is transferred to an output shift register. A dummy 0 bit is output first, followed by the 8-bit byte or 16bit word, with the most significant bit first. Output data changes are triggered by the rising edge of Serial Clock (C). The M93Cx6 automatically increments the internal address register and clocks out the next byte (or word) as long as the Chip Select Input (S) is held High. In this case, the dummy 0 bit is not output between bytes (or words) and a continuous stream of data can be read. Erase/Write Enable and Disable The Erase/Write Enable (EWEN) instruction enables the future execution of erase or write instructions, and the Erase/Write Disable (EWDS) instruction disables it. When power is first applied, the M93Cx6 initializes itself so that erase and write instructions are disabled. After an Erase/Write Enable (EWEN) instruction has been executed, erasing and writing remains enabled until an Erase/ Write Disable (EWDS) instruction is executed, or until V CC falls below the power-on reset threshold voltage. To protect the memory contents from accidental corruption, it is advisable to issue the Erase/Write Disable (EWDS) instruction after every write cycle. The Read Data from Memory (READ) instruction is not affected by the Erase/ Write Enable (EWEN) or Erase/Write Disable (EWDS) instructions.

Erase The Erase Byte or Word (ERASE) instruction sets the bits of the addressed memory byte (or word) to 1. Once the address has been correctly decoded, the falling edge of the Chip Select Input (S) starts the self-timed Erase cycle. The completion of the cycle can be detected by monitoring the Ready/ Busy line, as described in the READY/BUSY STATUS section. Write For the Write Data to Memory (WRITE) instruction, 8 or 16 data bits follow the op-code and address bits. These form the byte or word that is to be written. As with the other bits, Serial Data Input (D) is sampled on the rising edge of Serial Clock (C). Figure 5. ERASE, ERAL Sequences
ERASE S CHECK STATUS D 1 1 1 An A0
After the last data bit has been sampled, the Chip Select Input (S) must be taken Low before the next rising edge of Serial Clock (C). If Chip Select Input (S) is brought Low before or after this specific time frame, the self-timed programming cycle will not be started, and the addressed location will not be programmed. The completion of the cycle can be detected by monitoring the Ready/Busy line, as described later in this document. Once the Write cycle has been started, it is internally self-timed (the external clock signal on Serial Clock (C) may be stopped or left running after the start of a Write cycle). The cycle is automatically preceded by an Erase cycle, so it is unnecessary to execute an explicit erase instruction before a Write Data to Memory (WRITE) instruction.

Erase All The Erase All Memory (ERAL) instruction erases the whole memory (all memory bits are set to 1). The format of the instruction requires that a dummy address be provided. The Erase cycle is conducted in the same way as the Erase instruction (ERASE). The completion of the cycle can be detected by monitoring the Ready/Busy line, as described in the READY/BUSY STATUS section. Write All As with the Erase All Memory (ERAL) instruction, the format of the Write All Memory with same Data (WRAL) instruction requires that a dummy address be provided. As with the Write Data to Memory (WRITE) instruction, the format of the Write All Memory with same Data (WRAL) instruction requires that an 8-bit data byte, or 16-bit data word, be provided. This value is written to all the addresses of the memory device. The completion of the cycle can be detected by monitoring the Ready/Busy line, as described next.

READY/BUSY STATUS
While the Write or Erase cycle is underway, for a WRITE, ERASE, WRAL or ERAL instruction, the Busy signal (Q=0) is returned whenever Chip Select Input (S) is driven High. (Please note, though, that there is an initial delay, of tSLSH, before this status information becomes available). In this state, the M93Cx6 ignores any data on the bus. When the Write cycle is completed, and Chip Select Input (S) is driven High, the Ready signal (Q=1) indicates that the M93Cx6 is ready to receive the next instruction. Serial Data Output (Q) remains set to 1 until the Chip Select Input (S) is brought Low or until a new start bit is decoded.
CLOCK PULSE COUNTER
In a noisy environment, the number of pulses received on Serial Clock (C) may be greater than the number delivered by the master (the microcontroller). This can lead to a misalignment of the instruction of one or more bits (as shown in Figure 7.) and may lead to the writing of erroneous data at an erroneous address. To combat this problem, the M93Cx6 has an onchip counter that counts the clock pulses from the start bit until the falling edge of the Chip Select Input (S). If the number of clock pulses received is not the number expected, the WRITE, ERASE, ERAL or WRAL instruction is aborted, and the contents of the memory are not modified. The number of clock cycles expected for each instruction, and for each member of the M93Cx6 family, are summarized in Table 5. to Table 7.. For example, a Write Data to Memory (WRITE) instruction on the M93C56 (or M93C66) expects 20 clock cycles (for the x8 organization) from the start bit to the falling edge of Chip Select Input (S). That is: 1 Start bit + 2 Op-code bits + 9 Address bits + 8 Data bits
COMMON I/O OPERATION
Serial Data Output (Q) and Serial Data Input (D) can be connected together, through a current limiting resistor, to form a common, single-wire data bus. Some precautions must be taken when operating the memory in this way, mostly to prevent a short circuit current from flowing when the last address bit (A0) clashes with the first data bit on Serial Data Output (Q). Please see the application note AN394 for details.
