Overview
PCA8576C Automotive LCD driver for low multiplex rates Rev.
3 — 8 April 2015 Product data sheet 1.
General description The PCA8576C 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 and can easily be cascaded for larger LCD applications.
The PCA8576C 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 and by hardware subaddressing.
For a selection of NXP LCD segment drivers, see Table 21 on page 45.
