Products - GPL08A2

General Description

The GPL08A2, a CMOS 8-bit single chip microprocessor, is designed for low power applications. With only one battery (1.5V), it is capable of processing remarkable LCD graphics. By using advanced technology and mechanism, it contains RAM, ROM, I/Os, an interrupt controller, and an automatic display controller/driver for LCD. In the GPL08A2, a software controllable standby switch is built-in to save the power. It is very suitable for LCD type hand-held products.
