VFD Controller

1 General Description

The ePVP6810 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, 10-bit A/D

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

2. Feature
