System-on-Chip
Color LCD Controller (CLCDC)
connects to the AHB. It translates pixel-coded data into
the required formats and timings to drive single/dual
monochrome and color LCD panels. Packets of pixel-
coded data are fed, via the AHB interface, to two inde-
pendently programmable, 32-bit-wide DMA FIFOs.
Each FIFO is 16 words deep by 32 bits wide.

interrupt condition becomes true for upper/lower panel

tion, vertical compare, or bus error.

ADVANCED LCD INTERFACE
connection to ultra-thin panels that do not include a tim-
ing ASIC. It converts TFT signals from the Color LCD
controller to provide the proper signals, timing and levels
for direct connection to a panel’s Row and Column driv-
ers for AD-TFT, HR-TFT, or any technology of panel that
allows for a connection of this type. The ALI also pro-
vides a bypass mode that allows interfacing to the built-
in timing ASIC in standard TFT and STN panels.
NOTES:
1. The Advanced LCD Interface pertains to the LH75401 and
2. VGA and XGA modes require 66 MHz core speed.
