s DESCRIPTION

The S1C60N08 Series is a single-chip microcomputer made up of the 4-bit core CPU S1C6200C, ROM (4,096

words

× 12 bits), RAM (832 words × 4 bits), LCD driver, serial interface, event counter with dial input function,

watchdog timer, and two types of time base counter. Because of its low-voltage operation and low power consump-

tion, this series is ideal for a wide range of applications, and is especially suitable for battery-driven systems.

The S1C60R08 is a microcomputer with a CMOS 4-bit core CPU S1C6200C as main component, and a built-in

programmable RAM (ROM emulator). The S1C60R08 has almost the same functions as the S1C60N08/60A08.

The mask ROM in the S1C60N08/60A08 has been changed to a ROM emulator that allows the user to rewrite

programs using a Serial EEPROM.
