General Description
GPL813P01A, a CMOS 8-bit microprocessor, combines RAM, ROM, I/Os, an interrupt controller, and an automatic display controller/driver in a small device. The extraordinary features allow system to operate under a voltage range from 2.0V ~ 5.5V. This device is applicable for many application fields such as low power watch and other LCD related products.
