Features, Applications

The S3C70F2/C70F4 single-chip CMOS microcontroller has been designed for high-performance using Samsung's newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers). The S3P70F4 is the microcontroller which has 4 Kbyte one-time-programmable ROM and the functions are the same to S3C70F2/C70F4. With a four-channel comparator, eight LED direct drive pins, serial I/O interface, and its versatile 8-bit timer/counter, the S3C70F2/C70F4 offers an excellent design solution for a wide variety of general-purpose applications. to 24 pins of the 30-pin SDIP package can be dedicated to I/O. Five vectored interrupts provide fast response to internal and external events. In addition, the S3C70F2/C70F4's advanced CMOS technology provides for very low power consumption and a wide operating voltage range all at a very low cost.

SAM47 CPU All S3C7-series microcontrollers have the advanced SAM47 CPU core. The SAM47 CPU can directly address 32 K bytes 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 operations in two cycles. CPU REGISTERS Program Counter A 11-bit program counter (PC) stores addresses for instruction fetch during program execution. Usually, the PC is incremented by the number of bytes of the instruction being fetched. An exception is the 1-byte instruction REF which is used to reference instructions stored in a look-up table in the ROM. Whenever a reset operation or an interrupt occurs, bits PC11 through PC0 are set to the vector address. Bit PC1312 is reserved to support future expansion of the device's ROM size. Stack Pointer An 8-bit stack pointer (SP) stores addresses for stack operations. The stack area is located in the generalpurpose data memory bank 0. The SP is read or written by 8-bit instructions and SP bit 0 must always be set to logic zero. During an interrupt or a subroutine call, the PC value and the program status word (PSW) are saved to the stack area in RAM. 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 regardless of data memory access enable flag status. Since the reset value of the stack pointer is not defined in firmware, it is recommended that the stack pointer be initialized 00H by program code. This sets the first register of the stack area to data memory location 0FFH. PROGRAM MEMORY In its standard configuration, the 8-bit ROM is divided into three functional areas: 16-byte area for vector addresses 96-byte instruction reference area 1920-byte general purpose area (S3C70F2) 3968-byte general purpose area (S3C70F4) The vector address area is used mostly during reset operations and interrupts. These 16 bytes can also be used as general-purpose ROM. The REF instruction references 1-byte and 2-byte instructions stored in locations 0020H007FH. The REF instruction can also reference 3-byte instructions such JP or CALL. In order for REF to be able to reference these instructions, however, JP or CALL must be shortened 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 locations in the instruction reference area can be allocated to general-purpose use.
