GPL15B1中文资料96dots 8bits LCD controller, up to 72KB ROM LCD Game, TOY, Time-Piece数据手册Generalplus规格书

描述 Description

The GPL15B1 is a CMOS 8-bit single chip microprocessor which contains RAM, ROM, I/Os, interrupt controller, 8-bit PWM audio output and automatic display controller/driver for LCD. For power saving, a software controllable standby switch is also built-in. This chip is implemented with advanced design and process technology. It is very suitable for LCD type handheld products. The ROM space of this chip can be used to store program or audio data. (The speech data is about 18 seconds at 7KHz sampling rate by using 4bit-ADPCM)
