DESCRIPTION
The S1C88816 microcomputer features the S1C88 (MODEL 3) CMOS 8-bit core CPU along with a 116K bytes
of ROM, an 8K bytes of RAM, three different timers, a serial interface with optional asynchronization or clock
synchronization, a melody generator and an A/D converter. The S1C88816 has large capacity of ROM and
RAM and fully operable over a wide range of voltages. Furthermore, it can perform high speed operations even
at low voltage. Like all the equipment in the S1C Family, these microcomputers have low power consumption.
