GMS81C50 Series

CMOS SINGLE-CHIP 8-BIT MICROCONTROLLER

FOR UR (Universal Remocon) & KEYBOARD

1. OVERVIEW

1.1 Description

The GMS81C50 Series is an advanced CMOS 8-bit microcontroller with 16K/24K/32K bytes of ROM. The device is one of

GMS800 family. The LG Semicon GMS81C50 Series is a powerful microcontroller which provides a highly flexible and

cost effective solution to many UR & Keyboard applications. The GMS81C50 Series provides the following standard fea-

tures: 16K/24K/32K bytes of ROM, 448 bytes of RAM, 8-bit timer/counter, on-chip oscillator and clock circuitry. In addi-

tion, the GMS81C50 Series supports power saving modes to reduce power consumption.
