W66881CF GENERAL DESCRIPTION The W66881CF is a VFD (Vacuum Fluorescent Display) controller/driver. It has two operation configurations: (1) 8×16 Configuration which replaces the W66880CF without the necessity of changing the original driver program for W66880CF, and (2) 8×20 Configuration which provides more segment drivers, and can be programmed to drive a VFD from 4 grids by 20 segments to 8 grids by 18 segments. The W66881CF also includes a 24-key key scan circuit, four LED ports and four general purpose input ports. Data communication with the W66881CF is via a serial interface.
