描述 Description

GPL083B1, 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 include the capability of operating in low voltage range from 1.15V ~ 3.6V and also operating under low power that is suitable for solar cell environment.  It also provides built-in internal power switch to select two-way power sources automatically and facilitates user applying for solar cell and battery cooperation application.  This device is suitable for many application fields such as low power calculator and other LCD related products requiring either only one solar cell or battery application, or even two-way power source.
