www.DataSheet4U.com UC1681u 68x98RGB CSTN Controller-Driver UC1681u Single-Chip, Ultra-Low Power 68COM x 294SEG Matrix Passive Color LCD Controller-Driver INTRODUCTION UC1681u is an advanced high-voltage mixedsignal CMOS IC, especially designed for the display needs of ultra-low power hand-held devices. This chip employs UltraChip’s unique DCC (Direct Capacitor Coupling) driver architecture to achieve near crosstalk free images, with well balanced gray shades and vivid colors. In addition to low power COM and SEG drivers, UC1681u contains all necessary circuits for high-VLCD power supply, bias voltage generation, timing generation and graphics data memory. Advanced circuit design techniques are employed to minimize external component counts and reduce connector size while achieving extremely low power consumption. Support industry standard 2-wire, 3-wire, 2 3/4-wire, and 4-wire serial bus (I C, S9, S8uc, S8), and 8-bit/4-bit parallel bus (8080 or 6800). Special driver structure and gray shade modulation scheme. Ultra-low power consumption under all display patterns. No power consumption or image quality penalty when used with video rate CSTN Fully programmable Mux Rate, partial display window, Bias Ratio and Line Rate allow many flexible power management options. Software programmable four temperature compensation coefficients. Self-configuring 7x charge pump with onchip pumping capacitors Flexible data addressing/mapping schemes to support wide ranges of software models ...
