LC450029PKB Overview
ENA1916 LC450029PKB CMOS IC 1/4 and 1/3-Duty General-Purpose LCD Display Driver http://onsemi. Overview The LC450029PKB is 1/4 duty and 1/3 duty general-purpose microcontroller-controlled LCD drivers that can be used in applications such as frequency display in products with electronic tuning. In addition to being capable to drive up to 208 segments directly.
LC450029PKB Key Features
- Selectable 1/4-duty or 1/3-duty drive by the serial control data
- 1/3-bias only
- Serial data input supports CCB- format munication with the system controller. (For 5V operation only)
- The power-saving mode is selectable by the serial control data, and supports low power consumption
- Adjustable the frame frequency of the mon and segment output waveforms by the serial control data
- Selectable the internal oscillator operating or external clock operating mode by the serial control data
- High generality, since display data is displayed directly without the intervention of a decoder circuit
- The INH pad allows all LCD segments to be forced to the off state
- With a built-in oscillator circuit (External resistors and capacitors are unnecessary.)
- The stability of the LCD bias voltage is high by a built-in LCD bias generator with voltage-follower buffers
