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.

• 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 'computer control bus' format (for 5 V and 3 V)
• 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
