PCA85134H/Q900/1,1

PCA85134 Automotive 60 x 4 LCD segment driver for multiplex rates up to 1:4 Rev. 2 — 6 May 2014 Product data sheet 1. General description The PCA85134 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 60 segments. It can be easily cascaded for larger LCD applications. The PCA85134 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 26 on page 45. 2. Features and benefits                   1.
