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 MagnaChip HMS87C1X0XA is a
powerful microcontroller which provide a highly flexible and cost effective solution to many small applications such as controller for bat-
tery 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, 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 the HMS87C1304A,
the other’s eliminated functions are same as below.
