INFRARED REMOTE CONTROL TRANSMITTERS

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.
