1. general description the pca85262 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 32 segments. it can be easily cascaded for larger lcd applications. t he pca85262 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, 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. features and benefits ? aec-q100 grade 2 compliant for automotive applications ? single chip lcd controller and driver ? selectable backplane drive configuration: static, 2, 3, or 4 backplane multiplexing ? selectable display bias configuration: static, 1 2 , or 1 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 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 105 ? c ? 400 khz i 2 c-bus interface ? no external components required ? manufactured in silicon gate cmos process pca85262 32 x 4 automotive lcd driver for low multiplex rates rev. 1 ? 11 february 2014 product data sheet 1. the definition of the abbreviations and acronyms used in this data sheet can be found in section 22 .
