CMOS SINGLE-CHIP 8-BIT MICROCONTROLLER

1. OVERVIEW

1.1 Description

The HMS87C1X0XA is an advanced CMOS 8-bit microcontroller with 4K/2K bytes of EPROM. The Hynix

HMS87C1X0XA is a powerful microcontroller which provide a highly flexible and cost effective solution to many small

applications such as controller for battery charger. The HMS87C1X0XA provides the following standard features: 4K/2K

bytes of EPROM, 128bytes of RAM, 8-bit timer/counter, 8-bit A/D converter, 10-bit high speed PWM output, programmable

buzzer driving port, power-on reset circuit, on-chip oscillator and clock circuitry. In addition, the HMS87C1X0XA supports

power saving modes to reduce power consumption.

This document is only explained for the base of HMS87C1304A, the other’s eliminated functions are same as below.
