UC8276
All-in-one driver IC with Timing Controller for
White/Black/Red Dot-Matrix Micro-Cup ESL
I
NTRODUCTION
The UC8276 is an all-in-one driver with timing controller for
ESL. Its output is of 1-bit white/black and 1-bit red resolution
per pixel. The timing controller provides control signals for
source driver and gate driver.
The DC-DC controller allows it to generate the source
output voltage VSH/VSL (±2.4V~±15.0V) and VDHR
(2.4V~15.0V). The chip also includes an output buffer for
the supply of the COM electrode (AC-VCOM or DC-VCOM).
The system is configurable through a 3-wire/4-wire (SPI)
serial interface.
