PRODUCT DESCRIPTION
The WFP6852A is a 6-bit, 300-channel signal
driver designed for low power SVGA TFT-LCD
panel applications. The WFP6852A’s form factor
has been optimized for low-cost, bending TCP
applications.
The input pin order and timing are
compatible with drivers from TI and NEC.
The WFP6852A’s internal architecture includes a
resistor-string DAC with the value of the individual
resistor segments weighted to reduce signal
driver power dissipation by as much as 20% to
60% when compared to non-weighted resistor
string DAC architectures.
The input pin order and timing of the WFP6852A
allows the panel maker to get the benefits of the
Winbond architecture (such as superior uniformity,
low power dissipation, and 2.5V interface for
reduced EMI and power) while maintaining multi-
source compatibility.
The WFP6852A also provides input selectable
double edge clocking and data inversion features.
These may be employed in applications that don’t
need TI/NEC compatibility.
