ePVP6200

VFD Controller

1 General Description

The ePVP6200 is an 8-bit RISC type vacuum fluorescent display (VFD) controller equipped

with low power consumption and high speed CMOS technology. This integrated single chip

features on_chip watchdog timer (WDT), one time programming ROM (OTP), data RAM,

programmable real time clock/counter, internal interrupt, power down mode, built-in four-wire

SPI, IR detector, and high voltage output for VFD application.

2. Feature

2.1 CPU

Clock source：Crystal Oscillator

Crystal Oscillator (32.768KHz): with a external crystal

8k x 13 on chip Program ROM.
