GPL082A数据手册Generalplus中文资料规格书

描述 Description

GPL082A, a special designed CMOS 8-bit microprocessor by Generalplus, offers the best cost/performance ratio in the industry. It combines RAM, 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 1.2V ~ 1.7V and also operating under low power that is suitable for solar cell environment. It also builds in internal power switch to select two way power sources and facilitates user applying for solar cell and battery co-operation application. This device is capable for many application fields such as low power calculator, watch and other LCD related products required either only one solar cell or battery application, or even two way power source .
