S3C70F2 Datasheet | Samsung Semiconductor

OVERVIEW PRODUCT OVERVIEW OVERVIEW 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 parator, 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. Up 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. 1-1 PRODUCT OVERVIEW S3C70F2/C70F4/P70F4 FEATURES SUMMARY Memory - - Bit Sequential Carrier - 512 × 4-bit data memory (RAM) 2048 × 8-bit program memory (ROM):S3C70F2 4096 × 8-bit program memory (ROM):S3C70F4 Supports 16-bit serial data transfer in arbitrary format Interrupts - - - 24 I/O Pins - - Two external interrupt vectors Three internal interrupt vectors Two quasi-interrupts Data memory bank 15 I/O: 18 pins, including 8 high current pins Input only: 6 pins 4-channel mode: Internal reference (4-bit resolution) 16-step variable reference voltage 3-channel mode: External reference 150 m V resolution (worst case) Programmable interval timer Watch-dog timer parator - Memory-Mapped I/O Structure - Two Power-Down Modes - - - Idle mode: Only CPU clock stops Stop mode: System clock stops 8-bit Basic Timer - - OSCILLATION SOURCES - - - Crystal, Ceramic for system clock Crystal/ceramic: 0.4 - 6.0 MHz CPU clock divider circuit (by 4. 8, or 64) 8-bit Timer/Counter 0 - - Programmable interval timer External event counter function Timer/counter clock output to TCLO0 pin Time interval generation: 0.5...
