　The GMS81C2020 and GMS81C2120 are an advanced CMOS 8-bit microcontroller with 20K/12K 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: 20K/12K 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 Basic Interval Timer, 7-bit Watch dog Timer,8-bit, 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 GMS81C2020 and GMS81C2120 support power saving modes to reduce power consumption.
