GPL873P12A, a CMOS 8-bit microprocessor, combines RAM, External 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 1.1V ~ 1.8V. This device is applicable for many application fields such as low power watch and other LCD related products.
- adjustable CPU clock speed: 1, 1/2, 1/4, 1/8, 1/16 for ROSC
