| www..com UC1602 65x102 Matrix LCD Controller-Drivers UC1602(i) Single-Chip, Ultra-Low Power 65COM x 102SEG Passive Matrix LCD Controller-Driver INTRODUCTION UC1602(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, UC1602(i) contain all necessary circuits for highV LCD power supply, bias voltage generation, timing generation and graphics data memory. * Support industry standard 8-bit parallel interface (8080 or 6800), 4-wire SPI (S8), 2 and 2-wire I C serial interface. Two multiplexing rates (49, 65). 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. * * * * Advanced circuit design techniques are employed to minimize external component counts * On-chip bypass capacitor for VLCD makes .com and reduce connector size while achieving VLCD bypass capacitor optional for small extremely low power consumption. LCD panels. MAIN APPLICATIONS * Cellular Phones, Smart Phones, and other battery operated devices and/or portable Instruments * * On-chip Power-ON Reset and Software RESET commands, make RST pin optional. VDD (digital) range: 2.4V ~ 3.3V VDD (analog) range: 2.4V ~ 3.3V LCD VOP range: 4.5V ~ 10.5V Available in gold bump dies Bump pitch: 55M min. Bump gap: 20M min.
