NTRODUCTION
UC1682 is an advanced high-voltage mixed-
signal 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.

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.

ISCLAIMER
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 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 OTP memory cell is sensitive to photon excitation. Under extended exposure to strong ambient light, the OTP cells
can lose its content before the specified memory retention time span. The system designer is advised to provide proper
light shields to realize full OTP content retention performance.
