The GPL02E2 is a CMOS 8-bit single chip micro-processor. With GENERALPLUS state-of-the-art technology, it contains RAM, ROM, I/Os, one interrupt controller, two tone-generator, one noise generator, and one automatic display controller/driver. In addition, both PWM and current DAC audio outputs are provided in GPL02E2. Depending on the application, users are welling to select one of the audio types through mask option. To reduce power consumption, a software controllable standby switch is built-in to save the power. The GPL02E2 is a low cost but powerful IC that targets to fulfill various LCD application needs.
