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.
