onductor.The GN1621 LCD Driver with SSOP-48 is a RoHS-compliant device manufactured by GN Semiconductor. It is designed for driving and interfacing with active matrix liquid-crystal displays. This device features an industry-standard serial peripheral interface (SPI), 48-pin small outline package (SSOP) with power integrity, low EMI emissions, and good power dissipation. The GN1621 controls polarity and brightness of display elements, and can drive in the range of 2V to 5.5V. Its LCD driving current of up to 25 mA enables fast response time and display accuracy. The GN1621 also features an integrated charge pump which allows the LCD driving voltage to be generated from a single +4.5 V to +5.5V power supply. This device is designed to use a SPI interface for data communication and control. Furthermore, the GN1621 is suitable for embedded LCD display applications in consumer electronic products.
