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 (built-in resistor and capacitor for oscillation)
7. Selectable fundamental clock operating modes by serial data: internal oscillator operating mode or external clock
operating mode
8. Input of serial data supports CCB* format (for 5V and 3V)
9. Selectable voltage range of power supply for logic block by setting REGE pad
(VDD): +4.5V to +5.5V (5V power supply (REGE=VDD))
+2.7V to +3.6V (3V power supply (REGE=VSS))
10. Built-in quadruple and quintuple voltage booster with discharge function
Base voltage of boosting (VBTI2): +3.2V (Typ.) (5V power supply (REGE=VDD))
(VBTI1=VBTI2): +2.7V to VDD[V] (3V power supply (REGE=VSS))
11. Power supply for LCD driver block (VLCD): +16.0V (Typ.) (VDD=5V, Quintuple voltage booster is used.)
+16.5V
(VDD=3.3V, Quintuple voltage booster is used.)
+4.5V to +16.5V (range with external power supply)
