Liquid Crystal Display (S08LCDV1)
9.1.1 Features
The LCD module driver module features include:
• Low-power LCD waveform mode
• LCD waveforms functional in wait and stop3 low-power modes
• Selectable frontplane/backplane configuration
— Up to 41 frontplanes
— Up to 4 backplanes
• Programmable LCD frame frequency
• Programmable blink modes and frequency
— Independent blink control for each LCD segment
— Blink function remains active in stop3 mode
• Programmable LCD power supply switch making it an ideal solution for battery powered and
board level applications
— Requires only four external capacitors
— Internal LCD power using V_DD (1.8 to 3.6 V)
— External V_LCD power supply option (0.9 to 1.8 V)
• Integrated charge pump for LCD
— Hardware configurable to drive 3-V or 5-V LCD panels
— On-chip generation of bias voltages, adjustable charge pump frequency
• Dedicated LCD RAM
• LCD frame frequency interrupt event
• Internal ADC channels are connected to V_LL1 and V_LCD to monitor their magnitudes.This feature
makes it possible to adjust the contrast by software.
• Low-power, low-voltage CMOS technology
