Atmel | SMART ARM-based Embedded MPU
DATASHEET
Description
The Atmel® | SMART SAMA5D4 Series is a high-performance, power-efficient
ARM® Cortex®-A5 processor-based MPU capable of running at up to 600 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 devices have three software-selectable low-power modes: Idle,
Ultra-low-power, and Backup. In Idle mode, the processor is stopped while all
other functions can be kept running at normal operating bus frequency. In Ultra-
low-power mode, the processor is stopped while all other functions can be kept
running at minimum operating bus frequency. In Backup mode, only the real-time
clock, real-time timer, backup SRAM, backup registers, and wakeup logic are
running.
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 touchscreen 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 include 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, SHA function and TRNG. These features protect the system against
counterfeiting, safeguard sensitive data, authenticate safe programs and 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 make the SAMA5D4 well
suited for secure gateways or for the IoT.
