OVERVIEW
www.DataSheet4U.com
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.
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.
