GPLB32A5中文资料LCD Controller数据手册Generalplus规格书

描述 Description

The GPLB32A5, an 8-bit CMOS microprocessor, contains 1216 bytes of working RAM, 512K bytes of ROM, 8 I/Os, interrupt/wakeup controller, UART for serial communication and Serial SRAM interface for memory expansion, and automatic display controller/driver for LCD. It also features one PWM/DAC driver with two audio channels to produce attractive sound effects easily. Its large ROM area can be used to store both program and audio data. The built-in UART speeds up data transmission between two devices. Furthermore, a SLEEP (power-down) function is also built in to extend power life. The GPLB32A5 is designed with GENERALPLUS state-of-the-art technology to fulfill LCD application needs, specifically for hand-held products.
