GPL12A/B中文资料360dots 8bits LCD controller, up to 8KB ROM LCD Game, TOY, Time-Piece数据手册Generalplus规格书

描述 Description

Generalplus GPL12A is the mask-version of GPL11B(OTP) which features a CMOS 8-bit single chip Micro-controller containing LCD drivers, 8K bytes ROM, SRAM, I/O, timer/counter, PLL/ROSC, audio/remote control out, and resistor to frequency converter (RFC) function, all in one chip.  The GPL12A is designed to drive LCD directly and to perform sophisticated functions as well as complex arithmetic.  With the on-chip crystal oscillator, the real-time clock can be easily approached.  For power savings, several power-down modes are controllable by software.  The GPL12A is widely used for low power electronic products, e.g. remote controller and general-purpose LCD controller.
