CMOS SINGLE- CHIP 8-BIT MICROCONTROLLER

FOR UNIVERSAL REMOTE CONTROLLER

1. OVERVIEW

1.1 Description

The HMS81004E/08E/16E/24E/32E is an advanced CMOS 8-bit microcontroller with 4/8/16/24/32K bytes of ROM. The

device is one of GMS800 family. The HYNIX HMS81004E/08E/16E/24E/32E is a powerful microcontroller which provides

a highly flexible and cost effective solution to many UR applications.The HMS81004E/08E/16E/24E/32E provides the fol-

lowing standard features: 4/8/16/24/32K bytes of ROM, 448 bytes of RAM, 8-bit timer/counter, on-chip oscillator and clock

circuitry. In addition, the HMS81004E/08E/16E/24E/32E supports power saving modes to reduce power consumption.
