GPLB30A中文资料LCD Controller数据手册Generalplus规格书

描述 Description

The GPLB30A, an 8-bit CMOS microprocessor, contains 2752 bytes working RAM, 96K bytes ROM, 7 I/Os, interrupt/wakeup controller, UART for serial communication, Serial SRAM interface and Bus memory interface for memory expansion, and automatic display controller/driver for LCD. It also features one PWM 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 GPLB30A is designed with state-of-the-art technology to fulfill LCD application needs, especially for hand-held products.
