GPL811P04A(OTP)数据手册Generalplus中文资料规格书

描述 Description

GPL811P04A, a special designed CMOS 8-bit microprocessor by Generalplus, offers the best cost/performance ratio in the industry. It combines RAM, one-time programmable (OTP) ROM, I/Os, an interrupt controller, and an automatic display controller/driver in a small device.Its extraordinary features is the capability of operating in low voltage range from 2.2V ~ 3.6V and also operating under low power. This device is capable for many application fields such as low power watch and other LCD related products.
