The PCF21xxC family are single-chip 16-bit high-performance LCD drivers suitable for a wide range of applications. These devices are highly integrated, low-power, and offer serial data input, CBUS control, a single-point built-in oscillator, stand-alone or expanded system, power-on reset clear, and other features.
The PCF21xxC family consists of single-chip, silicon gate CMOS LCD driver circuits designed for serial data transfer with microcontrollers via a 3-line bus (CBUS) structure. These devices offer low current consumption and include a one-point built-in oscillator. They are compatible with CMOS/NMOS inputs and provide power-on reset clear functionality. The family includes specific models for 40, 64, and 32 LCD segments, superseding the earlier PCF21xx family with a reduced maximum operating voltage of 6.0 V.
