PCF85132

LCD driver for low multiplex rates

Rev. 3 — 15 July 2013

Product data sheet

1. General description

The PCF85132 is a peripheral device which interfaces to almost any Liquid Crystal

Display (LCD)¹with low multiplex rates. It generates the drive signals for any static or

multiplexed LCD containing up to four backplanes and up to 160 segments. It can easily

be cascaded for larger LCD applications. The PCF85132 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).

2. Features and benefits

 Single-chip LCD controller and driver for up to 640 elements

 Selectable backplane drive configuration: static, 2, 3, or 4 backplane multiplexing

 160 segment drives:

 Up to 80 7-segment numeric characters

 Up to 40 14-segment alphanumeric characters

 Any graphics of up to 640 elements

 May be cascaded for large LCD applications (up to 5120 elements possible)

 160  4-bit RAM for display data storage

 Software programmable frame frequency in steps of 5 Hz in the range of 60 Hz to

90 Hz; factory calibrated

 Wide LCD supply range: from 1.8 V for low threshold LCDs and up to 8.0 V for

guest-host LCDs and high threshold (automobile) twisted nematic LCDs

 Internal LCD bias generation with voltage-follower buffers

 Selectable display bias configuration: static, ¹⁄₂, or ¹⁄₃

 Wide power supply range: from 1.8 V to 5.5 V

 LCD and logic supplies may be separated

 Low power consumption, typical: I_DD= 4 A, I_DD(LCD)= 30 A

 400 kHz I²C-bus interface

 Auto-incremental display data loading across device subaddress boundaries

 Versatile blinking modes

 Compatible with Chip-On-Glass (COG) technology

 No external components required

 Two sets of backplane outputs for optimal COG configurations of the application
