■ DESCRIPTION
The E0C63358 is a microcomputer which has a high-performance 4-bit CPU E0C63000 as the core CPU, ROM
(8,192 words × 13 bits), RAM (512 words × 4 bits), serial interface, watchdog timer, programmable timer, time
base counter (1 system), SVD circuit, a segment type LCD driver that can drive a maximum 32 segments × 4
commons, a 4-channel A/D converter and a special input port that can implement key position discrimination
function using with the A/D converter. The E0C63358 features low voltage/high speed (4MHz Max.) operation
and low current consumption while the LCD is ON (current consumption in HALT: 2.5µA), this makes it suitable
for battery driven portable equipment such as a head phone stereo.
