1. OVERVIEW
1.1 Description
The HMS87C1304A and HMS87C1302A are an advanced CMOS 8-bit microcontroller with 4K/2K bytes of EPROM. The
HYUNDAI MicroElectronics HMS87C1304A and HMS87C1302A are powerful microcontroller which provides a highly
flexible and cost effective solution to many small applications such as controller for battery charger. The HMS87C1304A
and HMS87C1302A provide 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 HMS87C1304A and HMS87C1302A supports power saving modes to
reduce power consumption.
