| UC1605 80x128/4S Matrix LCD Controller-Drivers UC1605(i) Single-Chip, Ultra-Low Power 80COM x 128SEG Matrix Passive LCD Controller-Driver Special driver structure and gray shade modulation scheme. Sharp image and ultralow power consumption under all display patterns. Support four multiplexing rates (40, 50, 64, 80), four frame rates and 48-32-48 partial display function. Self-configuring 6x charge pump with onchip pumping capacitor requires only 3 external capacitors to operate. Flexible data addressing/mapping schemes to support wide ranges of software models and LCD layout placements. Software programmable 4 temperature compensation coefficients. On-chip bypass capacitor for VLCD makes VLCD bypass capacitor optional for small LCD panels. On-chip power-ON reset and software RESET commands, make RST pin optional. Very low pin count (9-pin, with I2C) allows exceptional image quality in COG format on conventional ITO glass. VDD (digital) range: 2.4V ~ 3.3V VDD (analog) range: 2.4V ~ 3.3V LCD VOP range: 6.5V ~ 11V Available in gold bump dies Bump pitch: 55uM min. Bump gap: 20uM min. INTRODUCTION UC1605(i) 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. In addition to low power COM and SEG drivers, UC1605(i) contains all necessary circuits for high-V LCD 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. MAIN APPLICATIONS Cellular Phones, Smart Phones, PDA and other battery operated palm top devices and/or portable Instruments FEATURE HIGHLIGHTS Single chip controller-driver supports 4shade-per-pixel, 80 COM x 128 SEG LCD, with vertical scroll and soft ICON support. Available either with or without I2C license. Support industry standard 8-bit parallel interface (8080 or 6800), 4-wire SPI (S8), 2 and 2-wire I C serial interface. Revision 1.5 1 ULTRACHIP High-Voltage Mixed-Signal IC (c)1999-2002 ORDERING INFORMATION Product ID UC1605IGAB UC1605xGAB Description 80 COM x 128 SEG LCD driver, with I2C interface license. 80 COM x 128 SEG LCD driver, no I2C interface license. Version 1.0 1.5 Contents First release Over all document revision Date of revision 10-30-2001 06-21-2002 General Notes APPLICATION INFORMATION For improved readability, the specification contains many application data points. When application information is given, it is advisory and does not form part of the specification for the device. USE OF I C The implementation of I C is already included and tested in all silicon. However, unless I C licensing obligation is 2 2 executed satisfactorily, it is not legal to use UltraChip product for I C applications. Unless I C version is ordered from UltraChip, the customer will take the responsibility for all such licensing liabilities. BARE DIE DISCLAIMER All die are tested and are guaranteed to comply with all data sheet limits up to the point of wafer sawing for a period of ninety (90) days from the date of UltraChip's delivery. There is no post waffle saw/pack testing performed on individual die. Although the latest modern processes are utilized for wafer sawing and die pick-&-place into waffle pack carriers, UltraChip has no control of third party procedures in the handling, packing or assembly of the die. Accordingly, it is the responsibility of the customer to test and quality their application in which the die is to be used. UltraChip assumes no liability for device functionality or performance of the die or systems after handling, packing or assembly of the die. LIFE SUPPORT APPLICATIONS These devices are not designed for use in life support appliances, or systems where malfunction of these products can reasonably be expected to result in personal injuries. Customer using or selling these products for use in such applications do so at their own risk. 2 2 2 2 Revision 1.5 UC1605 80x128/4S Matrix LCD Controller-Drivers BLOCK DIAGRAM PAGE ADDRESS GENERATOR ROW ADDRESS GENERATOR DATA RAM I/O BUFFER POWER-ON & RESET CONTROL COLUMN ADDRESS GENERATOR LEVEL SHIFTER CLOCK & TIMING GEN.
