The Atmel? SMART SAMA5D4 Series is a high-performance, power- efficient ARM?

Cortex?-A5 processor MPU capable of running up to 528 MHz. It integrates the ARM

NEON? SIMD engine for accelerated signal processing, multimedia and graphics as well

as a 128 KB L2-Cache for high system performance. The device features the ARM

TrustZone? enabling a strong security perimeter for critical software, as well as several

hardware security features. The device also features advanced user interface and

connectivity peripherals.

The SAMA5D4 features an internal multi-layer bus architecture associated with 32 DMA

channels to sustain the high bandwidth required by the processor and the high-speed

peripherals. The device supports DDR2/LPDDR/LPDDR2 and SLC/MLC NAND Flash

memory with 24-bit ECC.

The comprehensive peripheral set includes a 720p hardware video decoder, an LCD

controller with overlays for hardware- accelerated image composition, a resistive touch

screen function, and a CMOS sensor interface. Connectivity peripherals include a dual

10/100 Ethernet MAC with IEEE1588, three HS USB ports, UARTs, SPIs and I2Cs.

Security features includes an “on

-the-

fly” encryption

-decryption process from the external

DDR memory, tamper detection pins, secure storage of critical data, an integrity check

monitor (ICM) to detect modification of the memory contents and a secure boot. The

product also includes a dedicated coprocessor for public key cryptography such as RSA

and elliptic curves algorithms (ECC), as well as AES, 3DES, hashing function and TRNG.

These features permit to protect the system against counterfeiting, to safeguard sensitive

data, authenticate safe program or secure external data transfers.

The SAMA5D4 series is optimized for control panel/HMI applications needing video

playback and applications that require high levels of connectivity in the industrial and

consumer market. Its security features makes the SAMA5D4 well suited for secure

gateways or for the IoT.
