1. OVERVIEW
1.1 Description
The GMS81C5108 is an advanced CMOS 8-bit microcontroller with 8K bytes of ROM. The device is one of GMS800 fam-
ily. The Hynix GMS81C5108 is a powerful microcontroller which provides a high flexibility and cost effective solution to
many LCD applications. The GMS81C5108 provides the following standard features: 8K bytes of ROM, 192 bytes of RAM,
37 Nibbles of Display RAM, 8/16-bit timer/counter, on-chip oscillator and clock circuitry. In addition, the GMS81C5108
supports power saving modes to reduce power consumption.
This document is only explained for the base of GMS81C5108, the eliminated functions are same as below.
