LC450210PCH: Dot-Matrix LCD Controller Driver, 1/8 to 1/16 Duty
The LC450210PCH is the 1/8 to 1/16 duty dot matrix LCD controller driver. By controlling this driver with a microcontroller, it is used in applications such as character display and simple graphic display etc. This driver can drive a LCD panel of up to 3,200 dots (16 x 16 dot font: 1-line display of up to 12 digits and 128 segments, 5 x 7 dot font: 2-line display of up to 40 digits). The operating temperature range is from -40 to +105 [°C].
Features- Selectable duty ratio by serial data : 1/8 duty to 1/16 duty
- Selectable LCD bias voltage ratio by serial data : 1/4 bias or 1/5 bias
- Selectable inversion drive of LCD drive waveform by serial data : line inversion or frame inversion
- Adjustable frame frequency of common and segment output waveforms and clock frequency of voltage booster by serial data, for preventing interference with the frequency of the backlight.
- Selectable operation modes by serial data :power-saving mode (maintains display data), the state of display (ON, all ON, all OFF, all forced OFF)
- Built-in oscillator circuit (built-in resistor and capacitor for oscillation)
- Selectable fundamental clock operating modes by serial data :internal oscillator operating mode or external clock operating mode
- Input of serial data supports CCB format (for 5V and 3V)
- Selectable voltage range of power supply for logic block by setting REGE pad (VDD)
- Built-in quadruple and quintuple voltage booster with discharge function
- Power supply for LCD driver block (VLCD)
- Built-in contrast adjuster
- The initialization of this driver and the prevention of an unintended display are controllable by setting RES pad.
- Wide range of operating temperature: -40 to +105 [°C]
- CMOS process and chip with Au bumps
