Functional overview

STM32F479xx

44/217

DocID028010 Rev 3

The major features are:

•

Combined Rx and Tx FIFO size of 4 KB with dynamic FIFO sizing

•

Supports the session request protocol (SRP) and host negotiation protocol (HNP)

•

8 bidirectional endpoints

•

16 host channels with periodic OUT support

•

Software configurable to OTG1.3 and OTG2.0 modes of operation

•

USB 2.0 LPM (Link Power Management) support

•

Internal FS OTG PHY support

•

External HS or HS OTG operation supporting ULPI in SDR mode. The OTG PHY is

connected to the microcontroller ULPI port through 12 signals. It can be clocked using

the 60 MHz output.

•

Internal USB DMA

•

HNP/SNP/IP inside (no need for any external resistor)

•

for OTG/Host modes, a power switch is needed in case bus-powered devices are

connected

2.37

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 sustain a data transfer rate up to 54 Mbyte/s at 54 MHz. 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 black & white.

2.38

Cryptographic accelerator

The devices embed a cryptographic accelerator. This cryptographic accelerator provides a

set of hardware acceleration for the advanced cryptographic algorithms usually needed to

provide confidentiality, authentication, data integrity and non repudiation when exchanging

messages with a peer.

•

These algorithms consists of:

Encryption/Decryption

–

DES/TDES (data encryption standard/triple data encryption standard): ECB

(electronic codebook) and CBC (cipher block chaining) chaining algorithms, 64-

,128- or 192-bit key

–

AES (advanced encryption standard): ECB, CBC, GCM, CCM, and CTR (counter

mode) chaining algorithms, 128, 192 or 256-bit key
