HMS81C2012A/HMS81C2020A
CMOS Single-Chip 8-Bit Microcontroller
with A/D Converter & VFD Driver
1. OVERVIEW
1.1 Description
The HMS81C2012A and HMS81C2020Aare advanced CMOS 8-bit microcontroller with 12K/20K bytes of ROM. These
are a powerful microcontroller which provides a highly flexible and cost effective solution to many VFD applications. These
provide the following standard features: 12K/20K bytes of ROM, 448 bytes of RAM, 8-bit timer/counter, 8-bit A/D convert-
er, 10-bit High Speed PWM Output, Programmable Buzzer Driving Port, 8-bit Basic Interval Timer, 7-bit Watch dog Timer,
Serial Peripheral Interface, on-chip oscillator and clock circuitry. They also come with high voltage I/O pins that can directly
drive a VFD (Vacuum Fluorescent Display). In addition, the HMS81C2012A and HMS81C2020A support power saving
modes to reduce power consumption.
