Description
The Atmel | SMART SAMA5D2 Series is a high-performance, power-efficient embedded MPU based on the ARM
Cortex-A5 processor. It integrates the ARM NEON SIMD engine for accelerated multimedia and signal processing,
a configurable 128-Kbyte L2 cache, a floating point unit for high-precision computing and reliable performance, as
well as high data bandwidth architecture. The device features an advanced user interface and connectivity
peripherals. Advanced security is provided by powerful cryptographic accelerators, by the ARM TrustZone
technology securing access to memories and sensitive peripherals, and by several hardware features that
safeguard memory content, authenticate software reliability, detect physical attacks and prevent information
leakage during code execution.
The SAMA5D2 features an internal multilayer bus architecture associated with 2 x 16 DMA channels and
dedicated DMAs for the communication and interface peripherals required to ensure uninterrupted data transfers
with minimal processor overhead. The device supports DDR2, DDR3, DDR3L, LPDDR1, LPDDR2, LPDDR3, and
SLC/MLC NAND Flash memory up to 32-bit ECC.
The comprehensive peripheral set includes an LCD TFT controller with overlays for hardware-accelerated image
composition, an image sensor controller, audio support through I
2
S, SSC, a stereo Class D amplifier and a digital
microphone. Connectivity peripherals include a 10/100 EMAC, USBs, CAN-FDs, FLEXCOMs, UARTs, SPIs and
two QSPIs, SDIO/SD/e.MMCs, and TWIs/I
2
C.
Protection of code and data is provided by automatic scrambling of memories and an Integrity Check Monitor
(ICM) to detect any modification of the memory contents. The SAMA5D2 also supports execution of encrypted
code (QSPI or one portion of the DDR) with an “on-the-fly” encryption-decryption process.
With its secure design architecture, cryptographic acceleration engines, and secure boot loader, the SAMA5D2 is
the ideal solution for point-of-sale (POS), IoT and industrial applications requiring anti-cloning, data protection and
secure communication transfer.
SAMA5D2 devices feature 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.
In Ultra-low-power-mode 0, the processor is stopped while all other functions are clocked at 512 Hz and interrupts
or peripherals can be configured to wake up the system based on events, including partial asynchronous wakeup
(SleepWalking).
In Ultra-low-power mode 1, all clocks and functions are stopped but some peripherals can be configured to wake
up the system based on events, including partial asynchronous wakeup (SleepWalking).
In Backup mode, RTC and wakeup logic are active. The Backup mode can be extended to feature DDR in Self-
refresh mode.
SAMA5D2 devices also include an Event System that allows peripherals to receive, react to and send events in
Active and Idle modes without processor intervention.
