com Single-Chip, Ultra-Low Power 128COM x 128SEG Matrix Passive LCD Controller-Driver INTRODUCTION UC1617s is an advanced high-voltage mixedsignal CMOS IC, especially designed for the display needs of low power hand-held devices.
This chip employs UltraChip’s unique DCC (Direct Capacitor Coupling) driver architecture and FRM (Frame Rate Modulation) gray-shade modulation scheme to achieve near crosstalk free images, with well balanced gray shades.
In addition to low power COM and SEG drivers, UC1617s contains all necessary circuits for highV LCD power supply, bias voltage generation, temperature compensation, 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.
x Special driver structure and gray shade modulation scheme.
Consistent low power consumption under all display patterns.
Fully programmable Mux Rate, partial display window, Bias Ratio and Line Rate allow many flexible power management options.
Four software programmable frame rates up to 201Hz.
Support the use of fast Liquid Crystal material for speedy LCD response.
Software programmable 4 temperature compensation coefficients.
On-chip Power-ON Reset and Software RESET command, make RST pin optional.
Self-configuring 9x charge pump with onchip pumping capacitors.
Only 3 external capacitors are required to operate.
Flexible data addressing/mapping schemes to support wide ranges of software models and LCD layout placements.
Very low pin count (9~10 pins with S8, S9, or I2C) 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.
