产品信息

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. The internal oscillation circuit helps to reduce the number of external resistors and capacitors required. The chip shape is slim for COG (Chip-On-Glass) implementation. The operating temperature range is from -40°C to +105°C

Selectable 1/4-duty or 1/3-duty drive by the serial control data
When 1/4-duty : Capable of driving up to 208 segments
When 1/3-duty : Capable of driving up to 159 segments
1/3-bias only
Serial data input supports 'computer control bus' format communication with the system controller. (For 5 V operation only)
The power-saving mode is selectable by the serial control data, and supports low power consumption.
Adjustable the frame frequency of the common 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.
Shipping form: Chip with Au bumps in tray.
Allowable operating voltage (VDD, VDDI) : +4.5 V to +6.0 V
Allowable wide operating temperature ranges : -40°C to +105°C
