GPLB30B中文资料640 Dots LCD Controller with 48KB ROM数据手册Generalplus规格书

描述 Description

The GPLB30B, an 8-bit CMOS microprocessor, contains 2240 bytes working RAM, 48K bytes ROM, 16 I/Os, interrupt/wakeup controller, and automatic display controller/driver for LCD. Furthermore, a SLEEP (power-down) function is also built in to extend power life. The GPLB30B is designed with state-of-the-art technology to fulfill LCD application needs, especially for hand-held products.
