CMOS SINGLE-CHIP 8-BIT MICROCONTROLLER
1. OVERVIEW
1.1 Description
The HMS87C1X04B/08B/16B is an advanced CMOS 8-bit microcontroller with 4K/8K/16K bytes of ROM. The MagnaChip semicon-
ductor’s HMS87C1X04B/08B/16B is a powerful microcontroller which provides a highly flexible and cost effective solution to many em-
bedded control applications. The HMS87C1X04B/08B/16B provides the following standard features: 4K/8K/16K bytes of ROM, 448
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 HMS87C1X04B/08B/16B support power saving modes to re-
duce power consumption.
