PCA85233
Automotive 80 × 4 LCD driver for low multiplex rates
Rev. 5 — 12 November 2018
Product data sheet
1. General description
The PCA85233 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 PCA85233 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 28 on page 46.
