Overview
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 16 dot font: 1-line display of up to 12 digits and 128 segments, 5 7 dot font: 2-line display of up to 40 digits). The operating temperature range is from -40 to +105 [C].
Features
1. Selectable duty ratio by serial data: 1/8 duty to 1/16 duty
1/8 duty: 8 200 = 1,600 dots
1/11 duty: 11 200 = 2,200 dots
1/14 duty: 14 200 = 2,800 dots
1/9 duty: 9 200 = 1,800 dots
1/12 duty: 12 200 = 2,400 dots
1/15 duty: 15 200 = 3,000 dots
1/10 duty: 10 200 = 2,000 dots
1/13 duty: 13 200 = 2,600 dots
1/16 duty: 16 200 = 3,200 dots
2. Selectable LCD bias
voltage ratio by serial data: 1/4 bias or 1/5 bias
3. Selectable inversion drive of LCD drive waveform by serial data: line inversion or frame inversion
4. 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.
5. Selectable operation modes by serial data: power-saving mode (maintains display data),
the state of display (ON, all ON, all OFF, all forced OFF)
6. Built-in oscillator circuit ...
