Functional overview

3.28

Digital camera interface (DCMI)

The devices embed a camera interface that can connect with camera modules and CMOS

sensors through an 8-bit to 14-bit parallel interface, to receive video data. The camera

interface can achieve a data transfer rate up to 140 Mbyte/s using a 80 MHz pixel clock and

14-bit of data. It features:

•

Programmable polarity for the input pixel clock and synchronization signals

•

Parallel data communication can be 8-, 10-, 12- or 14-bit

•

Supports 8-bit progressive video monochrome or raw Bayer format, YCbCr 4:2:2

progressive video, RGB 565 progressive video or compressed data (like JPEG)

•

Supports continuous mode or snapshot (a single frame) mode

•

Capability to automatically crop the image

3.29

LCD-TFT display 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 up to

WXGA (1366×768) @60 fps resolution with the following features:

•

2 display layers with dedicated FIFO

•

Color look-up table (CLUT) up to 256 colors (256×24-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 4 programmable interrupt events

•

AXI master interface

3.30

True random number generator (RNG1, RNG2)

All the devices embed two RNG that deliver 32-bit random numbers generated by an

integrated analog circuit.

RNG1 can be defined (in ETZPC) as accessible by secure software only.
