Description
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.
