Description



Features:

• Single chip controller-driver for 80x104 matrix C-STN LCD with comprehensive support for input format and color depth: 8-bit RGB: 256 color 12-bit RGB: 4K color 16-bit RGB: 56K color (dithering) 24-bit RGB: 221K color (dithering)
• One software readable ID pin to support configurable vender identification.
• Partial scroll function and programmable data update window to support flexible manipulation of screen data.
• 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.
• Fully programmable Mux Rate, partial display window, Bias Ratio and Line Rate allow many flexible power management options.
• Software programmable frame rates up to 250Hz. Support the use of fast Liquid Crystal material for speedy LCD response.
• Software programmable four temperature compensation coefficients.

Description

UC1682 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, UC1682 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.
