GMS81C7208/16
CMOS SINGLE-CHIP 8-BIT MICROCONTROLLER
WITH LCD DRIVER & A/D CONVERTER
1. OVERVIEW
1.1 Description
The GMS81C7208/7216 is advanced CMOS 8-bit microcontrollers with 8K/16K bytes of ROM. There are a powerful microcontroller
which provides a highly flexible and cost effective solution to many LCD applications. These provide the following standard features:8K/
16K bytes of mask type ROM or 16K bytes OTP ROM, 448 bytes of RAM, 8-bit Timer/Counter, 8-bit A/D converter, programmable buzz-
er driving port, 8-bit basic interval timer, watch dog timer, serial peripheral interface, on chip oscillator and clock circuitry. They also come
with 4com/17seg LCD driver. In addition, it support power saving mode to reduce power consumption.
