www.DataSheet4U.com UC1681 68x98RGB CSTN Controller-Driver UC1681s INTRODUCTION Single-Chip, Ultra-Low Power 68COM x 294SEG Matrix Passive Color LCD Controller-Driver x x Support both row ordered and column ordered display buffer RAM access. Support industry standard 3-wire, 4-wire serial bus (S9, S8, S8uc) 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 8x charge pump with onchip pumping capacitors Flexible data addressing/mapping schemes to support wide ranges of software models and LCD layout placements. Very low pin count (10 pins with S9) allows exceptional image quality in COG format on conventional ITO glass. Many on-chip and I/O pad layout features to support optimized COG applications. VDD (digital) range: 1.8V ~ 3.3V VDD (analog) range: 2.5V ~ 3.3V 4.8V ~ 11.8V LCD VOP range: MTP VLCD trimming circuit to support precise LCD contrast matching Available in gold bump dies and COF: Bump pitch: 38 PM Bump gap: 15 PM 2 Bump surface: > 2369 PM UC1681s is an advanced high-voltage mixedsignal CMOS IC, especially designed for the display needs of ultra-low power hand-held devices.
