Microchip SAMA5D44
SAMA5D4 Series
SAMA5D41 /42 /43 /44
The SAMA5D4 Series is a high-performance, power-efficient Arm® Cortex®-A5 processor-based MPU capable of run-
ning 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 fre-
quency. 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 hard-
ware-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 detec-
tion 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.
