SPL10A1

7.5KB LCD CONTROLLER/DRIVER

GENERAL DESCRIPTION

The SPL10A1 is a CMOS 8-bit single chip micro-controller which contains LCD drivers,

ROM, SRAM, I/O, timer/counter and audio output on a single chip.

The SPL10A1 is designed to drive LCD directly and perform efficient controller function

as well as arithmetic function. With the on chip crystal oscillator, the clock function is

easily realized. For power saving, a software controllable standby switch is also built-in.

The SPL10A1 is widely used in electronic products requiring very low power operation, for

example, multi-function watch, calendar, calculator, thermometer or LCD game with audio

output.
