PCF2201
LCD FLAT-PANEL ROW/COLUMN DRIVER
GENERAL DESCRIPTION
The PCF2201 is a row or column LCD driver, designed to drive LCD flat-panels at multiplex rates
of up to 1 : 256. The PCF2201 converts serial or parallel 4-bit display data into parallel LCD drive wave-
forms, capable of driving up to 81 rows or 80 columns of an LCD matrix. The PCF2201 is cascadable,
enabling it to drive any LCD flat-panel matrix. The PCF2201 is controlled by an alphanumeric/graphic
controller.
