PCF85133
Universal LCD driver for low multiplex rates
Rev. 3 — 4 July 2014
Product data sheet
1. General description
The PCF85133 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 80 segments and can easily
be cascaded for larger LCD applications. The PCF85133 is compatible with most
microcontrollers and communicates via the two-line bidirectional I2C-bus. Communication
overheads are minimized by a display RAM with auto-incremental addressing, by
hardware subaddressing and by display memory switching (static and duplex drive
modes).
For a selection of NXP LCD segment drivers, see Table 27 on page 45.
2. Features and benefits
Single-chip LCD controller and driver
Selectable backplane drive configuration: static or 2, 3, or 4 backplane multiplexing
Selectable display bias configuration: static, 12, or 13
Selectable frame frequency: 82 Hz or 110 Hz
Internal LCD bias generation with voltage-follower buffers
80 segment drives:
Up to 40 7-segment numeric characters
Up to 20 14-segment alphanumeric characters
Any graphics of up to 320 elements
80 4 bit RAM for display data storage
Auto-incremental display data loading across device subaddress boundaries
Display memory bank switching in static and duplex drive modes
Versatile blinking modes
Independent supplies possible for LCD and logic voltages
Wide power supply range: from 1.8 V to 5.5 V
Wide logic LCD supply range:
From 2.5 V for low-threshold LCDs
Up to 6.5 V for guest-host LCDs and high-threshold twisted nematic LCDs
Low power consumption
400 kHz I2C-bus interface
May be cascaded for large LCD applications (up to 5120 elements possible)
May be cascaded with PCF8532 to gain more flexibility in the number of addressable
segments
