This`advanced,`highly`integrated`LCD`controller`drives`up`to`eight`backplanes,`up`to`44`segments,`

and`up`to`320`elements,`and`provides`an`on-chip,`6-channel`PWM`controller`for`LED`illumination.`

Compatible`with`most`MCUs,`it`simplifies`design,`reduces`power,`and`minimizes`communication`

overhead.

The`NXP`PCx8536`is`a`peripheral`device,`equipped`with``

drives`almost`any`LCD`display`with`multiplex`rates`up`to`1:8.`

The`device`is`available`in`two`types,`one`for`industrial`

(PCF8536)`and`one`for`automotive`applications`(PCA8536).``

The`automotive`type`supports`an`extended`operating`

temperature`range`up`to`95`°C,`and`is`AEC`Q100`compliant.`

Both`types`are`also`compatible`with`most`microcontrollers`and`

communicate`via`standard`serial`interfaces.`The`AT`versions`

versions`use`the`three-line`unidirectional`SPI-bus`(5`MHz).`

Communication`overheads`are`minimized`by`using`a`320-bit`

display`RAM`with`auto-incremented`addressing.

An`on-chip`PWM`controller`for`LED`backlight`illumination``

is`included.`The`PWM`has`six`outputs`with`7-bit`resolution``

(128`steps)`ideal`to`drive`external`transistors.`Up`to`six`

independent`channels`can`be`configured.`The`128`levels``
