1OUTLINE
The S1C63406 is a microcomputer which has a high-performance 4-bit CPU S1C63000 as the core
CPU, code ROM (6,144 words
× 13 bits), RAM (1,024 words × 4 bits), data ROM (3,072 words × 4 bits),
serial interface, watchdog timer, programmable timer, time base counters (2 systems) and a dot-matrix
LCD driver that can drive a maximum 60 segments
× 9 commons. Furthermore, the built-in reset circuit
(with power-on reset function) can detect the power supply voltage to reset the S1C63406 when the
power is turned on or an instantaneous power interruption occurs. The S1C63406 features high speed
operation with a low operating voltage (1.3 V to 3.6 V) and low current consumption, this makes it
suitable for applications working with batteries, such as portable MD and CD player systems.
