KS57C0404/C0408/P0408 MICROCONTROLLER PRODUCT OVERVIEW 1 PRODUCT OVERVIEW The KS57C0404/C0408 single-chip CMOS microcontroller has been designed for very high-performance using Samsung's newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers). The KS57P0408 is the microcontroller which has 8K-bytes one-time-programmable ROM and the functions are same to KS57C0404/C0408. With two 8-bit timer/counters, an 8-bit serial I/O interface, and eight software n-channel open-drain I/O pins, the KS57C0404/C0408 offers an excellent design solution for a wide variety of general-purpose applications. Up to 36 pins of the 42-pin SDIP or 44-pin QFP package can be dedicated to I/O. Seven vectored interrupts provide fast response to internal and external events. In addition, the KS57C0404/C0408's advanced CMOS technology provides for low power consumption and a wide operating voltage range. 1-1 PRODUCT OVERVIEW KS57C0404/C0408/P0408 MICROCONTROLLER FEATURES SUMMARY Memory * * * 512 x 4-bit RAM 4096 x 8-bit ROM: KS57C0404 8192 x 8-bit ROM: KS57C0408 Bit Sequential Carrier * Supports 16-bit serial data transfer in arbitrary format Interrupts * * * 3 external interrupt vectors 4 internal interrupt vectors 2 quasi-interrupts 36 I/O Pins * * * Input only: 4 pins I/O: 24 pins N-channel open-drain I/O: 8 pins Power-Down Modes * * Idle: Only CPU clock stops Stop: System clock stops Memory-Mapped I/O Structure * Data memory bank 15 8-Bit Basic Timer * 4 interval timer functions Oscillation Sources * * * Crystal or Ceramic for system clock Oscillation frequency : 0.4 - 6.0MHz CPU clock divider circuit (by 4. 8, or 64) Two 8-Bit Timer/Counters * * * Programmable interval timer External event counter function Timer/counters clock outputs to TCLO0 and TCLO1 pins Instruction Execution Times * * 0.95, 1.91, 15.3 s at 4.19 MHz 0.67, 1.33, 10.7 s at 6.0 MHz Watch Timer * * Time interval generation: 0.5 s, 3.9 ms at 4.19 MHz 4 frequency outputs to the BUZ pin Operating Temperature * - 40 C to 85 C Operating Voltage Range * * 1.8 V to 5.5 V (Main) 2.0 V to 5.5 V (OTP) 8-Bit Serial I/O Interface * * * 8-bit transmit/receive mode 8-bit receive mode LSB-first or MSB-first transmission selectable Package Types * 42-pin SDIP, 44-pin QFP 1-2 KS57C0404/C0408/P0408 MICROCONTROLLER PRODUCT OVERVIEW FUNCTION OVERVIEW SAM47 CPU All KS57-series microcontrollers have the advanced SAM47 CPU core. The SAM47 CPU can directly address up to 32K-byte of program memory. The arithmetic logic unit(ALU) performs 4-bit addition, subtraction, logical, and shift-and-rotate operations in one instruction cycle and most 8-bit arithmetic and logical operation in two cycles. CPU REGISTERS program counter A 12-bit program counter (PC) stores addresses for instruction fetches during program execution. Usually, the PC is incremented by the number of bytes of the fetched instruction. The one instruction fetch that does not increment the PC is the 1-byte REF instruction which references instruction stored in a look-up table in the ROM. Whenever a reset operation or an interrupt occurs, bits PC12 though PC0 are set to the vector address. Stack pointer An 8-bit stack pointer (SP) stores addresses for stack operation. The stack area is located in general-purpose data memory bank 0. The SP is 8-bit read/writeable and SP bit 0 must always be logic zero. During an interrupt or a subroutine call, the PC value and the PSW are written to the stack area. When the service routine has completed, the values referenced by the stack pointer are restored. Then, the next instruction is executed. The stack pointer can access the stack despite data memory access enable flag status. Since the reset value of the stack pointer is not defined in firmware, you use program code to initialize the stack pointer to 00H. This sets the first register of the stack area to data memory location 0FFH. PROGRAM MEMORY In its standard configuration, the 4096 x 8-bit (KS57C0404), 8192 x 8-bit (KS57C0408) ROM is divided into four areas: 16-byte area for vector addresses 96-byte instruction reference area 16-byte general-purpose area (0010 - 001FH) 3968-byte area for general-purpose program memory (KS57C0404) 8064-byte area for general-purpose program memory (KS57C0408) The vector address area is used mostly during reset operation and interrupts. These 16 bytes can alternately be used as general-purpose ROM. The REF instruction references 2x1-byte or 2-byte instruction stored in reference area location 0020H - 007FH. REF can also reference three-byte instruction such as JP or CALL. So that a REF instruction can reference these instruction, however, the JP or CALL must be shortened to a 2-byte format. To do this, JP or CALL is written to the reference area with the format TJP or TCALL instead of the normal instruction name. Unused location in the REF instruction look-up area can be allocated to general-purpose use. 1-3 PRODUCT OVERVIEW KS57C0404/C0408/P0408 MICROCONTROLLER DATA MEMORY Overview The 512 x 4bit data memory has five areas: 32 x 4-bit working register area 224 x 4-bit general-purpose area in bank 0 which is also used as the stack area 256 x 4-bit general-purpose area in bank 1 128 x 4-bit area in bank 15 for memory-mapped I/O addresses The data memory area is also organized as three memory banks bank0, bank1, and bank15. You use the select memory bank instruction (SMB) to select one of the banks as working data memory. Data stored in RAM location are 1-, 4-, and 8-bit addressable. After a hardware reset, data memory initialization values must be defined by program code. Data Memory addressing modes The enable memory bank (EMB) flag controls the addressing mode for data memory banks 0, 1, or 15. When the EMB flag is logic zero, only location 00H-7FH of bank 0 and bank 15 can be accessed. When the EMB flag is set to logic one, all three data memory banks can be accessed based on the current SMB value. Working registers The RAM's working register area in data memory bank 0 is also divided into four register banks. Each register bank has eight 4-bit registers. Paired 4-bit registers are 8-bit addressable. Register A can be used as a 4-bit accumulator and double register EA as an 8-bit extended accumulator; double registers WX, WL, and HL are used as address pointers for indirect addressing. To limit the possibility of data corruption due to incorrect register addressing, it is advisable to use bank 0 for main programs and banks 1, 2, and 3 for interrupt service routines. Bit sequential carrier The bit sequential carrier (BSC) mapped in data memory bank 15 is a 16-bit general register that you can manipulate using 1-, 4-, and 8-bit RAM control instructions. Using the BSC register, addresses and bit location can be specified sequentially using 1-bit indirect addressing instructions. In this way, a program can generate 16-bit data output by moving the bit location sequentially, incrementing or decrementing the value of the L register. You can also use direct addressing to manipulate data in the BSC. 1-4 KS57C0404/C0408/P0408 MICROCONTROLLER PRODUCT OVERVIEW CONTROL REGISTERS Program Status Word The 8-bit program status word (PSW) controls ALU operation and instruction execution sequencing. It is also used to restore a program's execution environment when an interrupt has been serviced. Program instructions can always address the PSW regardless of the current value of data memory access enable flags. Before an interrupt is processed, the PSW is pushed onto the stack in data memory bank 0. When the routine is completed, PSW values are restored. IS1 C IS0 SC2 EMB SC1 ERB SC0 Interrupt status flags (IS1, IS0), the enable memory bank and enable register bank flags (EMB, ERB), and the carry flag ( C ) are 1- and 4-bit read/write or 8-bit read-only addressable. Skip condition flags (SC0-SC2) can be addressed using 8-bit read instructions only. Select Bank (SB) Register Two 4-bit location called the SB register store address values used to access specific memory and register banks: the select memory bank register, SMB, and the select register bank register, SRB. 'SMB n' instructions select a data memory bank (0, 1, or 15) and store the upper four bits of the 12-bit data memory address in the SMB register. The 'SMB n' instruction is used to select register bank 0, 1, 2, or 3, and to store the address data in the SRB. The instructions 'PUSH SB' and 'POP SB' move SMB and SRB values to and from the stack for interrupts and subroutines. CLOCK CIRCUITS System oscillation circuit generates the internal clock signals for the CPU and peripheral hardwares. The system clock can use a crystal, ceramic, or RC oscillation source, or an externally-generated clock signal. To drive KS57C0404/C0408 using an external clock source, the external clock signal should be input to Xin, and its inverted signal to Xout. A 4-bit power control register is used to enable or disable oscillation, and to select the CPU clock. The internal system clock signal (fx) can be divided internally to produce three CPU clock frequencies fx/4, fx/8, or fx/64. INTERRUPTS Interrupt requests can be generated internally by on-chip processes (INTB, INTT0, INTT1, and INTS) or externally by peripheral devices (INT0, INT1, and INT4). There are two quasi-interrupts: INT2 and INTW. INT2/KS0-KS7 detects rising/falling edges of incoming signals and INTW detects time intervals of 0.5 seconds of 3.91 milliseconds at 4.19MHz. The following components support interrupt processing: Interrupt enable flags Interrupt request flags Interrupt priority registers Power-down termination circuit 1-5 PRODUCT OVERVIEW KS57C0404/C0408/P0408 MICROCONTROLLER POWER-DOWN To reduce power consumption, there are two power-down modes: idle and stop. The IDLE instruction initiates idle mode and the STOP instruction initiates stop mode. In idle mode, only the CPU clock stops while peripherals and the oscillation source continue to operate normally. Stop mode effects only the system clock. In stop mode system clock oscillation stops completely, halting all operations except for a few basic peripheral functions. RESET or an interrupt (with the exception of INT0) can be used to terminate either idle or stop mode. RESET When a RESET signal occurs during normal operation or during power-down mode, the CPU enters idle mode when the reset operation is initiated. When the standard oscillation stabilization interval (31.3 ms at 4.19 MHz) has elapsed, normal CPU operation resumes. I/O PORTS The KS57C0404/C0408 has 9 I/O ports. Pin addresses for all I/O ports are mapped to locations FF0H-FFCH in bank 15 of the RAM. There are 4 input pins, 24 configurable I/O pins, and 8 software n-channel open-drain I/O pins, for a total of 36 I/O pins. The contents of I/O port pin latches can be read, writen, or tested at the corresponding address using bit manipulation instructions. TIMERS AND TIMER/COUNTERS The timer function has four main components: an 8-bit basic interval timer, two 8-bit timer/counters, and a watch timer. The 8-bit basic timer generates interrupt requests at precise intervals, based on the selected CPU clock frequency. The programmable 8-bit timer/counters are used for external event counting, generation of arbitrary clock frequencies for output, and dividing external clock signals. The 8-bit timer/counter 0 generates a clock signal (SCK) for the serial I/O interface. The watch timer has an 8-bit watch timer mode register, a clock selector, and a frequency divider circuit. Its functions include real-time and watch-time measurement, and frequency outputs for buzzer sound. SERIAL I/O INTERFACE The serial I/O interface supports the transmission or reception of 8-bit serial data with an external device. The serial interface has the following functional components: 8-bit mode register Clock selector circuit 8-bit buffer register 3-bit serial clock counter The serial I/O circuit can be set either to transmit-and-receive or to receive-only mode. MSB-first or LSB-first transmission is also selectable. The serial interface operates with an internal or an external clock source, or using the clock signal generated by the 8-bit timer/counter 0. To modify transmission frequency, the appropriate bits in the serial I/O mode register (SMOD) must be manipulated. 1-6 KS57C0404/C0408/P0408 MICROCONTROLLER PRODUCT OVERVIEW BLOCK DIAGRAM BASIC TIMER INT0, INT1, INT2,INT4 8-BIT TIMER/ COUNTER 0 Xin Xout WATCH TIMER RESET P0.0 / SCK I/O PORT 0 INTERRUPT CONTROL BLOCK CLOCK INSTRUCTION REGISTER P0.1 / SO P0.2 / SI P0.3 / BTCO 8-BIT TIMER/ COUNTER 1 INTERNAL INTERRUPTS P4.0 - 4.3 P5.0 - 5.3 I/O PORT 4 INSTRUCTION DECODER I/O PORT 5 ARITHMETIC P6.0 - 6.3 / KS0 - S3 P7.0 - 7.3 / KS4 - S7 AND I/O PORT 6 LOGIC UNIT PROGRAM COUNTER SERIAL I/O P1.0 / INT0 P1.1 / INT1 P1.2 / INT2 P1.3 / INT4 P2.0 / TCLO0 INPUT PROGRAM STATUS WORD PORT 1 I/O PORT 2 STACK POINTER I/O PORT 3 P2.1 / TCLO1 P2.2 / CLO P2.3 / BUZ P3.0 / TCL0 P3.1 / TCL1 P3.2 P3.3 I/O PORT 7 P8.0 - 8.3 I/O PORT 8 512 x 4-BIT DATA MEMORY PROGRAM MEMORY 4 KBYTE: KS57C0404 8 KBYTE: KS57C0408 Figure 1-1.
