GMS87C1404 / GMS87C1408

CMOS SINGLE-CHIP 8-BIT MICROCONTROLLER

1. OVERVIEW

1.1 Description

The GMS87C1404 and GMS87C1408 are an advanced CMOS 8-bit microcontroller with 4K/8K bytes of EPROM. The

HYUNDAI MicroElectronics GMS87C1404 and GMS87C1408 are a powerful microcontroller which provides a highly

flexible and cost effective solution to many small applications such as controller for battery charger. The GMS87C1404 and

GMS87C1408 provide the following standard features: 4K/8K bytes of EPROM, 192 bytes of RAM, 8-bit timer/counter, 8-

bit A/D converter, 10-bit high speed PWM output, programmable buzzer driving port, 8-bit serial communication port, on-

chip oscillator and clock circuitry. In addition, the GMS87C1404 and GMS87C1408 supports power saving modes to reduce

power consumption.
