Low Current Consumption
High Speed Operation in Low Voltage
DESCRIPTION
The S1C63408 is a microcomputer which has a high-performance 4-bit CPU S1C63000 as the core CPU, code
ROM, RAM, data ROM, serial interface, watchdog timer, programmable timer, time base counters (2 systems)
and a dot-matrix LCD driver. Furthermore, the built-in reset circuit (with power-on reset function) can detect the
power supply voltage to reset the S1C63408 when the power is turned on or an instantaneous power
interruption occurs. The S1C63408 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.
