Techwell,Inc. TW8816 Evaluation Board User’s Manual
Different kinds of LCD panels usually require their specific connectors. Since there are no
standard connectors, the evaluation board has generic interfaces which are 8bits per color single
pixel LVDS, 6bit per colors single pixel TTL, and 8bits per color single pixel output pins for the
daughter boards. If the board was not provided with a proper cable for your panel, you need to
build a cable yourself.

6. Built-in Microcontroller Interface
The evaluation board has connectors on the left side of the board with reference CN14 and CN15.
These connectors may be used with the “Embed MCU with TW9910 daughter card” to utilize the
built-in microcontroller and the shared digital video interface available on the TW8816.
The built-in microcontroller may be used with the daughter card and the appropriate firmware.
Some of the features are:
-
Operation Keys ( 8 keys )
-
GPIOs
-
Remocon IR Receiver
-
UART
