PCA85276 Automotive 40 x 4 LCD driver Rev. 2 9 April 2015 Product data sheet 1. General description The PCA85276 is a peripheral device which interfaces to almost any Liquid Crystal 1 Display (LCD) 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. It can be easily cascaded for larger LCD applications. The PCA85276 is compatible with most 2 microcontrollers and communicates via the two-line bidirectional I C-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 24 on page 46. 2.
