1. General description
The PCF85176 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 40 segments. It can be easily
cascaded for larger LCD applications. The PCF85176 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).
2. Features and benefits
Single chip LCD controller and driver
Selectable backplane drive configuration: static, 2, 3, or 4 backplane multiplexing
Selectable display bias configuration: static,
