Products - GPL10B1

General Description

The GPL10B1 is a CMOS 8-bit single chip micro-controller which contains LCD drivers, ROM, SRAM, I/O, timer/counter and tone output for directly driving buzzer on a single chip. The GPL10B1 is designed to drive LCD directly and performs efficient controller function as well as arithmetic function. With the on chip crystal oscillator, the real time clock is easily realized. For power saving, a software controllable standby switch is also built-in. The GPL10B1 is widely used in electronic products requiring very low power consumption, for example, multi-function watch, calendar, calculator, and thermometer or LCD game with audio output.
