29 LCD - Liquid Crystal Display Driver
29.1 Introduction
29.2 Features
2010-09-06 - d0001_Rev1.00
The LCD driver is capable of driving a segmented LCD display with up to 4x40 segments. A voltage
boost function enables it to provide the LCD display with higher voltage than the supply voltage for the
device. In addition, an animation feature can run custom animations on the LCD display without any
CPU intervention. The LCD driver can also remain active even in Energy Mode 2 and provides a Frame
Counter interrupt that can wake-up the device on a regular basis for updating data.
• Up to 4x40 segments.
• Configurable multiplexing (1, 2, 3, 4)
• Configurable bias/voltage levels settings
• Configurable clock source prescaler
• Configurable Framerate
• Segment lines can be enabled or disabled in groups of 4
• Blink capabilities
• Integrated animation functionality
• Voltage boost capabilities
• Possible to run on external power
• Programmable contrast
• Frame Counter

What?
The LCD driver can drive up to 4x40
segmented LCD directly. The LCD driver
consumes less than 900 nA in EM2. The
animation feature makes it possible to have
active animations without CPU intervention.
Why?
Segmented LCD displays are common way to
display information. The extreme low-power
LCD driver enables a lot of applications to
utilize an LCD display even in energy critical
systems.
How?
The low frequency clock signal, low-power
waveform, animation and blink capabilities
enable the LCD driver to run autonomously
in EM2 for long periods. Adding the flexible
frame rate setting, contrast control, and
different multiplexing modes make the
EFM32G the optimal choice for battery-driven
systems with LCD panels.
