PCA8576C
Automotiove LCD driver for low multiplex rates
Rev. 2 — 16 December 2013
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 I
2
C-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.
