New Japan Radio Co., Ltd. announces the NJU6541A/B, LCD controller driver with key scan function which can display 480-Segment (max.) by One chip.
Recently, the increasing of digital audio and radio's popularity demands car-mounted LCD panels capable of displaying ever-growing volumes of text.
And due to fashion-oriented design, it is moving toward multi-segment type LCD panel integrating clock, air-conditioner and audio displays, called information panel. Additionally, high quality displays with wide view angle range are also in demand in information panel, so low duty ratio operating and multi-segment display are necessary functions in LCD control driver by above reasons. The NJU6541A and NJU6541B are 480-Segment (4Com×120Seg) LCD controller drivers developed to meet the market requests.
The NJU6541A/B have LCD controller/driver, electric volume for contrast control, power on reset circuit and key scan circuit. They are housed in LQFP144(22.0×22.0×1.75mm) package and can display 480-segment (4Com×120Seg Max.) LCD by One chip.Due to low duty ratio operation of static, 1/2, 1/3 and 1/4, the high display quality (wide view angle range) required for the information panel is achieved.
And the NJU6541A/B further incorporate a key scan circuit(5-out×6-in Matrix) and I2C interface(NJU6541A), so they lighten designer's burden. The operating temperature range is -40 to +105°C centigrade required from car audio equipments.The NJU6541A/B with multi-segment display function and high display quality, are suitable for car-mounted LCD panel called information panel.The NJU6541A/NJU6541B features;
|Function||4Com×120Seg (Max.480Seg) LCD Controller Driver|
