描述 Description

The HMS81C2012A are advanced CMOS 8-bit microcontroller with 12K bytes of ROM. Theseare a powerful microcontroller which provides a highly flexible and cost effective solution to many VFD applications. Theseprovide the following standard features: 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,Serial Peripheral Interface, on-chip oscillator and clock circuitry. They also come with high voltage I/O pins that can directlydrive a VFD (Vacuum Fluorescent Display). In addition, the HMS81C2012A supports power savingmodes to reduce power consumption.
