PCF8562
Universal LCD driver for low multiplex rates
Rev. 6 — 16 June 2011
Product data sheet
1. General description
The PCF8562 is a peripheral device which interfaces to almost any Liquid Crystal
Display (LCD)
1
with low multiplex rates. It generates the drive signals for any static or
multiplexed LCD containing up to four backplanes and up to 32 segments. The PCF8562
is compatible with most microcontrollers and communicates via the two-line bidirectional
I
2
C-bus. Communication overheads are minimized by a display RAM with
auto-incremented addressing, by hardware subaddressing and by display memory
switching (static and duplex drive modes).
