36.1 LCD_C Introduction
The LCD_C controller directly drives LCD displays by automatically creating the ac segment and common voltage signals. The LCD_C controller can support static and 2-mux to 8-mux LCD glasses.
The LCD_C controller features are:
- Display memory
- Automatic signal generation
- Configurable frame frequency
- Blinking of individual segments with separate blinking memory for static, and 2- to 4-mux LCDs
- Blinking of complete display for 5- to 8-mux LCDs
- Regulated charge pump up to 3.44 V (typical)
- Contrast control by software
- Support for the following types of LCDs
- Static
- 2-mux, 1/2 bias or 1/3 bias
- 3-mux, 1/2 bias or 1/3 bias
- 4-mux, 1/2 bias or 1/3 bias
- 5-mux, 1/3 bias
- 6-mux, 1/3 bias
- 7-mux, 1/3 bias
- 8-mux, 1/3 bias
The differences between LCD_B and LCD_C are listed in Table 36-1.
Table 36-1 Differences Between LCD_B and LCD_C
| Feature | LCD_B | LCD_C |
|---|---|---|
| Supported types of LCDs | Static, 2-, 3-, 4-mux | Static, 2-, 3-, 4-, 5-, 6-, 7, 8-mux |
| Maximum VLCDx settings | 001111b | 001111b |
| Maximum LCD voltage (VLCD,typ) | 3.44 V | 3.44 V |
| Supported biasing schemes for 5-mux to 8-mux | 5- to 8-mux not supported | 1/3 biasing |
Figure 36-1 shows the LCD controller block diagram.
NOTE
Maximum LCD Segment Control
The maximum number of segment lines and memory registers available differs with device. See the device-specific data sheet for available segment pins and the maximum number of segments supported.
