Passive Color LCD Controller-Driver

I
NTRODUCTION
UC1698u is an advanced high-voltage mixed-signal CMOS IC,
specially designed for the display needs of low power hand-
held devices.
In addition to low power COM and SEG drivers, UC1698u
contains all necessary circuits for high-V LCD power supply,
bias voltage generation, temperature compensation, timing
generation, and graphics data memory.
UC1698u employs UltraChip’s unique DCC (Direct Capacitor
Coupling) driver architecture and LRM (Line Rate Modulation)
gray-shade modulation scheme to achieve well balanced
shading, vivid colors, and natural-looking images while
supporting very fast Liquid Crystal material for video
applications.
With UC1698u, LCD makers can now achieve TFT-like image
quality, support video applications while maintaining the same
STN advantages in power consumption, unit cost, ease of
customization and production flexibility.

• Single chip controller-driver for 160x128 matrix C-STN
LCD with comprehensive support for input format and
color depth:
12-bit RGB: 4K-color
16-bit RGB: 64K-color
• Support monochrome STN and video rate CSTN
applications.
• Window-write, window-skip functions to support flexible
video applications such as OSD, dynamic service
provider screen saver for cell phone and others.
• ID pin (ID1)-switched input data sets (D[7:0] or D[0, 2, 4,
6, 8, 10, 12, 14]) for 8-bit mode.
• One ID pin (ID0) plus two programmable ID flags, totally
4 software-readable ID bits to support configurable
vender identification.
• Partial scroll function and programmable data update
window to support flexible manipulation of screen data.
• Supports both row-ordered and column-ordered display
buffer RAM access.
• Supports industry standard 4-wire, 3/4-wire, and 3-wire
serial buses (S8, S8uc, S9) and 16-bit/8-bit parallel
buses (8080 or 6800).
• Special driver structure and gray shade modulation
scheme. 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.
• Four software programmable temperature
compensation coefficients.
• Software programmable, self-configuring 10x charge
pump.
• Flexible data addressing/mapping schemes to support
wide ranges of software models and LCD layout
placements.
• Pad layouts support COG applications.

NFORMATION
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.

All die are tested and are guaranteed to comply with all data sheet limits up to the point of wafer sawing. There is no post waffle saw/pack testing
performed on individual die. Although the latest 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
qualify their applications 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.

ENSITIVITY
The MTP memory cell is sensitive to photon excitation and ESD. Under extended exposure to strong ambient light, or when TST4 pin is exposed to
ESD strikes, the MTP cells can lose its content before the specified memory retention time span. The system designer is advised to provide proper
light & ESD shields to realize full MTP content retention performance.
