GMS81C1404 / GMS81C1408
CMOS SINGLE-CHIP 8-BIT MICROCONTROLLER
1. OVERVIEW
1.1 Description
The GMS81C1404 and GMS81C1408 are an advanced CMOS 8-bit microcontroller with 4K/8K bytes of ROM. The Hynix
semiconductor’s GMS81C1404 and GMS81C1408 are a powerful microcontroller which provides a highly flexible and cost
effective solution to many small applications such as controller for battery charger. The GMS81C1404 and GMS81C1408
provide the following standard features: 4K/8K bytes of ROM, 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 GMS81C1404 and GMS81C1408 supports power saving modes to reduce power consump-
tion.
