2 GENERAL DESCRIPTION

The PCF21xxC family are single-chip, silicon gate CMOS
LCD driver circuits. A 3-line bus (CBUS) structure enables
serial data transfer with microcontrollers. All inputs are
CMOS/NMOS compatible.

The devices have the same function and performance as
those of the PCF21xx family, which they supersede.
The maximum operating voltage required is reduced from

6.5 to 6.0 V.
