PCF8536

I²C/SPI LCD and PWM LED controller for

industrial and automotive applications

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.

Key features

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

a`low-power`serial`interface`(I²C-`or`SPI-bus),`that`controls`and`

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

``Single-chip`320`segment`LCD`controller`and`driver

``6-channel`PWM`generator`for`backlight`LED`illumination`

``AEC`Q100`compliant`for`automotive`applications`(PCA8536)

``Selectable`display`bias`conﬁguration

``Wide`digital`supply`voltage`range:`1.8`to`5.5`V

``Wide`LCD`supply`voltage`range:`2.5`to`9.0`V

``Choice`of`serial`interface:`I²C`(PCx8536AT)`or`SPI`

(PCx8536BT)`

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.`

``Low`power`consumption

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

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

use`the`two-line`bidirectional`I²C-bus`(400`kHz),`while`the`BT`

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.

``Operating`temp`up`to`85`°C`(PCF8536)`or`95`°C`(PCA8536)

``Silicon`gate`CMOS`process

Applications

``Industrial`version`(PCF8536)

-`White`goods

-`Consumer`products

``Automotive`version`(PCA8536)

-`Car`radio

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``

-`Climate`control

-`Dashboard`display

per`channel`allow`to`control`2`RGB`backlights`with`a`spectrum` Hz.`The`reference`oscillator`is`factory`calibrated.`The`device`

of`more`than`2`million`colors.`Each`channel`can`also`be`used`

for`static`LED`drive`or`as`logic`output.

compensates`the`DC`offset`voltage`across`the`LCD`in`line`

inversion`mode,`or`in`frame`inversion`mode`(selectable).

The`PCx8536`generates`the`drive`signals`for`any`multiplexed`

LCD`containing`up`to`eight`backplanes,`up`to`44`segments,`

and`up`to`320`elements.`4,`6,`or`8`backplanes`can`be`driven.`

The`LCD`supply`range`from`2.5`V,`for`use`with`low-threshold`

LCDs,`up`to`9.0`V`for`high-threshold`TN`LCDs.`The`digital`

power`supply`can`be`from`1.8`to`5.5`V,`and`the`logic`supply`

can`be`separated`from`the`LCD`supply.`Also,`to`avoid`ﬂicker`

The`320`segments`can`include`up`to`40`seven-segment`digits,` of`the`display,`the`PWM`and`LCD`frame`frequencies`can`be`

up`to`20`fourteen-segment`alphanumeric`characters,`or`any`

graphic`of`up`to`320`elements.`The`frame`frequency`can`

be`programmed`in`the`range`of`60`to`300`Hz`in`steps`of`10`

set`independently.`Backplane`swapping`eases`PCB`design`

by`making`it`possible`to`move`the`backplane`and`segment`

outputs`from`one`side`to`the`other.`
