NJU6435

The NJU6435 is a 1/2 or 1/3 duty LCD driver for segment type LCD panel with key scan function.Display data and Key input data are communicated by serial data transmission,  therefore, the commmication between NJU6435 and MPU is performed by only 5 lines.80-segment or 120-segment  are displayed by 40-segment driver and 2- or 3-coiman driver.The key scan function scanning  up to  30 keys and the data is transferred to the MPU.The NJU6435 can design simple front panel,therefore it is easy to apply car mounted audio, general audio and other products which have a display and key input.

Features of the NJU6435 are:(1)40-segment drivers; (2)duty ratio and 1/2 duty, 1/2 bias  80-segment drive(version D),bias level 1/3 duty, 1/2 bias 120-segment drive(version E),1/3 duty, 1/3 bias 120-segment drive(version F); (3)30 Key scan function(6-out x 5-in matrix); (4)serial data transmission; (5)display off function(INH terminal); (6)operating voltage:5V±10%; (7)package outline:QFP 64; (8)C-MOS technology.

The absolute maximum ratings of the NJU6435 can be summarized as:(1)operating voltage Vdd:-0.3 to 7.0V;(2)storage temperature:-55 to +150;(3)operating temperature:-30 to 85 ;(4)output current:1.0mA;(5)input voltage:-0.3 to Vdd+7.0V.The information given herein, including the specifications and dimensions, is subject to change without prior notice to improve product characteristics.
