PCF85162 32 4 universal LCD driver for low multiplex rates Rev. 5.1 2 September 2021 Product data sheet 1 General description The PCF85162 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 PCF85162 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 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 6.5 V for guest-host LCDs and high-threshold twisted nematic LCDs Low power consumption 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 20.NXP Semiconductors PCF85162 32 4 universal LCD driver for low multiplex rates 3 Ordering information Table 1.Ordering information Type number Topside mark Package Name Description Version PCF85162T/1 PCF85162T SOT362-1 TSSOP48 plastic thin shrink small outline package, 48 leads body width 6.1 mm Standard packing quantities and other packaging data are available at www.nxp.com/ packages/. 3.1 Ordering options Table 2.Ordering options Type number Orderable part number Package Packing method Minimum Temperature order quantity 1 PCF85162T/1 PCF85162T/1,118 TSSOP48 reel 13 inch q1 non 2000 T = -40 C to +85 C amb dry pack PCF85162T/1Y TSSOP48 reel 13 inch q1 dry 2000 T = -40 C to +85 C amb pack 1 Discontinuation Notice 202107021DN - drop in replacement is PCF85162T/1Y - this is documented in PCN202102010F01.
