GPL08A5中文资料Low power 8 bit LCD controller w/ VLCD Regulator, Max 3072dots, up to 160KB ROM Calculator, Time-Piece数据手册Generalplus规格书

描述 Description

The GPL08A5, 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 GPL08A5, a software controllable standby switch is built-in to save the power.  It is very suitable for LCD type hand-held products.
