TXA5
Processor
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 comprehensive peripheral set
includes 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,
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.
