Wide view angle, key scan function and I 2C BUS control lighten designer's burden March 19,2009 New Japan Radio releases the NJU6541A,NJU6541B, 480-Segment LCD controller driver with key scan function 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 I 2C 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; • 4Com×120Seg (max.

• 30Key scan function (5-out×6-in Matrix). • Duty: Static,1/2,1/3,1/4 • Electric volume 8 levels. • Operation Wave Pattern Selectivity: A wave and B wave • Wide Operating Temperature Range: -40 to 105°C Product Name NJU6541A NJU6541B Function 4Com×120Seg (Max.480Seg) LCD Controller Driver Applications I 2C Interface Serial Interface Package Outline [ Features and Characteristics ] • LCD Operating Output 4Com×120Seg(Max.480Seg) • 30 Key scan function 5-output ×6-input Matrix • Interface NJU6541A: I 2C Interface / NJU6541B: Serial Interface • Programmable Duty Ration • Static: max.120Segments • 1/2 duty ratio: max. 240Segments • 1/3 duty ratio: max. 360Segments • 1/4 duty ratio: max. 480segments • Programmable Bias ratio 1/2 and 1/3 Bias ratio • Electric volume 8 Levels • Operation Wave Pattern Selectivity 'A' wave and 'B' wave • Serial Data Forwarding Shift clock 2MHz Max. • Oscillator • CR Oscillation with external R and C or External oscillation signal input • Operating Voltage 3V / 5V • CMOS Technology(P-Sub) • Package Outline LQFP144(22.0×22.0×1.75mm 0.50mm pitch) [ BLOCK DIAGRAM ].
