LCD-TFT controller (LTDC)

The LCD-TFT display controller provides a 24-bit parallel digital RGB (red, green, blue) and

delivers all signals to interface directly to a broad range of LCD and TFT panels with the

following features:

•

Two displays layers with dedicated FIFO (64 x 32-bit)

•

Color look-up table (CLUT) up to 256 colors (256 x 24-bit) per layer

•

Up to 8 input color formats selectable per layer

•

Flexible blending between two layers using alpha value (per pixel or constant)

•

Flexible programmable parameters for each layer

•

Color keying (transparency color)

•

Up to four programmable interrupt events

DSI Host (DSIHOST)

The DSI Host is a dedicated IP that interfaces with the MIPI® DSI compliant displays. It

includes a dedicated video interface internally connected to the LTDC and a generic APB

interface that can be used to transmit information to the display.

The interfaces are as follows:

•

LTDC interface:

–

Used to transmit information in Video Mode, in which the transfers from the host

processor to the peripheral take the form of a real-time pixel stream (DPI)

–

Used to transmit information in full bandwidth in the Adapted Command Mode

(DBI) through a custom mode

•

APB slave interface:

–

Allows the transmission of generic information in Command mode, and follows a

proprietary register interface

–

Can operate concurrently with either LTDC interface in either Video Mode or

Adapted Command Mode

•

Video mode pattern generator:

–

Allows the transmission of horizontal/vertical color bar and D-PHY BER testing

pattern without any kind of stimuli
