PCA85162 32 x 4 automotive LCD driver for low multiplex rates Rev. 4.1 16 September 2021 Product data sheet 1 General description The PCA85162 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 32 segments. It can be easily cascaded for larger LCD applications. The PCA85162 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. 2 Features and benefits AEC-Q100 compliant for automotive applications Single chip LCD controller and driver Selectable backplane drive configuration: static, 2, 3, or 4 backplane multiplexing 1 1 Selectable display bias configuration: static, , or 2 3 Internal LCD bias generation with voltage-follower buffers 32 segment drives: Up to 16 7-segment numeric characters Up to 8 14-segment alphanumeric characters Any graphics of up to 128 segments/elements 32 4-bit RAM for display data storage Display memory bank switching in static and duplex drive modes Versatile blinking modes Independent supplies possible for LCD and logic voltages Wide power supply range: from 1.8 V to 5.5 V Wide logic LCD supply range: From 2.5 V for low-threshold LCDs Up to 8.0 V for guest-host LCDs and high-threshold twisted nematic LCDs Low power consumption Extended temperature range up to 95 C 2 400 kHz I C-bus interface No external components required Manufactured in silicon gate CMOS process 1 The definition of the abbreviations and acronyms used in this data sheet can be found in Section 21.NXP Semiconductors PCA85162 32 x 4 automotive LCD driver for low multiplex rates 3 Ordering information Table 1.Ordering information Type number Topside Package mark Name Description Version PCA85162T/ PCA85162T plastic thin shrink small outline package 48 leads SOT362-1 TSSOP48 Q900/1 body width 6.1 mm 3.1 Ordering options Table 2.Ordering options Type number Orderable part Package Packing method Minimum Temperature 1 number order quantity PCA85162T/ PCA85162T/ TSSOP48 tape and reel, 13 inch 2000 T = -40 C to +95 C amb 2 Q900/1 Q900/1,1 PCA85162T/ PCA85162T/ TSSOP48 reel 13 inch q1 dry pack 2000 T = -40 C to +95 C amb Q900/1 Q900/1Y 1 Standard packing quantities and other packaging data are available at www.nxp.com/packages/ 2 Discontinuation notice 202107021DN - drop-in replacement is PCA85162T/Q900/1Y - this is documented in PCN202102010F01.
