PIC Microcontrollers with LCD

Segemented Displays

Segmented displays are used in a wide variety of

applications, ranging from meters to portable medical

devices to thermostats to exercise equipment. PIC MCUs

with integrated LCD drivers can directly drive segmented

displays with letters, numbers, characters and icons. The

main features of Microchip’s LCD portfolio include:

■ Flexible LCD segments

• 28 pins: up to 72 segments

• 44 pins: up to 116 segments

• 64 pins: up to 184 segments

• 80 pins: up to 192 segments

• 100 pins: up to 480 segments

■ Variable clock inputs

■ Integrated voltage bias generation

■ Direct drive for both 3V and 5V powered displays

■ Software contrast control for boosting or dimming for

different temperature or lighting conditions

■ Drive LCD while conserving power in Sleep mode

■ Integrated real time clock and calendar for displaying

time and date information

■ mTouch capacitive touch sensing capability

■ Crystal-free USB 2.0 options

Direct Drive for Segmented Displays

The LCD PIC microcontrollers support direct LCD panel

drive capability with no external components needed,

lowering total system cost. They have integrated voltage

bias generation which allows the MCU to generate the

different voltage levels that are required to drive the LCD

segment pins and provide good contrast for the display.

The LCD MCUs support a range of fixed and variable bias

options as well as variable clock inputs, giving you the

flexibility to work with many different glass vendors.

Contrast Control

Software contrast control is a key feature using firmware

to either boost or dim the contrast of the display. Boost

the contrast up to VDD or beyond if you are using one

of the MCUs with an integrated charge pump. Software

contrast control allows you to vary the contrast on the

LCD to account for different operating conditions such as

temperature, lighting and humidity. Also, software contrast

control can be invaluable for portable applications. As the

battery level starts to drop, the firmware can apply a boost

to the contrast helping extend the battery life while still

producing a crisp image on the display.
