The Liquid Crystal Display (LCD) controller
directly drives LCD displays through the segment (SEG) and common (COM) voltage
signals. The controller can support 2-mux to 8-mux LCD glasses. The main features of
the LCD controller are:
- Display memory
- Standby mode support
- Configurable SEG and COM pins
- Automatic signal generation
- Configurable frame frequency
- Blinking of individual segments with separate blinking memory for static and 2-4 mux LCD
- Blinking of complete display for 5-8 mux LCDs
- Regulated charge pump up to 3.6V (typical)
- Internal resistor divider for generating bias voltages
- Internal charge pump for
generating bias voltages
- Contrast control by software
- Ability to use LCD IOs as GPIOs or analog signals when pins are not used for LCD operation
- Supports static, 1/3 and 1/4 bias
modes. 1/2 bias mode is not supported.
