PCA85262

Automotive 32 x 4 LCD driver for low multiplex rates

Rev. 3 — 12 November 2018

Product data sheet

1. General description

The PCA85262 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 32 segments. It can be easily

cascaded for larger LCD applications. The PCA85262 is compatible with most

microcontrollers and communicates via the two-line bidirectional I²C-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).

For a selection of NXP LCD segment drivers, see Table 23 on page 46

2. Features and benefits

 AEC-Q100 grade 2 compliant for automotive applications

 Single chip LCD controller and driver

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

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

 Internal LCD bias generation with voltage-follower buffers

 32 segment drives:

 Up to 16 7-segment numeric characters

 Up to 8 14-segment alphanumeric characters

 Any graphics of up to 128 segments/elements

 32  4-bit RAM for display data storage

 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 8.0 V for guest-host LCDs and high-threshold twisted nematic LCDs

 Low power consumption

 Extended temperature range up to 105 C

 400 kHz I²C-bus interface

 No external components required
