For engineers reviewing the ATSAMA5D22B-CUR datasheet, ATSAMA5D22B-CUR pinout, ATSAMA5D22B-CUR application, or ATSAMA5D22B-CUR equivalent, this page delivers verified technical context, validated package mapping (256-ball TFBGA, 8×8 mm, 0.4 mm pitch), confirmed low-power modes (ULP0/ULP1/Backup), exact peripheral count (2 QSPI, 2 SDMMC, 5 FLEXCOM, 2 CAN-FD), and real-world security implementation details including on-the-fly DDR/QSPI encryption and 5-Kbyte scrambled SRAM with tamper detection.
Technical Context
The ATSAMA5D22B-CUR implements a full Armv7-A architecture with MMU, NEON SIMD engine, and floating-point unit (FPU), enabling Linux® OS execution and high-precision signal processing. Its multilayer bus architecture integrates two 16-channel 64-bit Central DMA Controllers and dedicated peripheral DMAs for zero-overhead data movement between GMAC, ISC, LCDC, and audio interfaces.
Security is enforced via Arm TrustZone partitioning, a dedicated Secure Advanced Interrupt Controller (SAIC), Integrity Check Monitor (ICM) with SHA256, and hardware-accelerated cryptographic engines compliant with FIPS PUB 197 (AES), FIPS PUB 180-2 (SHA), and NIST SP 800-22 (TRNG). The device supports secure boot with encrypted code execution from QSPI or DDR memory using AESB bridge.

FAQ
What is the maximum operating frequency of the ATSAMA5D22B-CUR?
The ATSAMA5D22B-CUR operates at a maximum CPU frequency of 500 MHz. This speed is achievable under typical thermal conditions with appropriate voltage regulation (VDDCORE = 1.25 V) and supported memory configurations (e.g., DDR3L at 1.35 V). The device includes dynamic voltage and frequency scaling (DVFS) support through its Power Management Controller (PMC), allowing runtime adjustment to balance performance and power consumption in battery-operated applications.
Does the ATSAMA5D22B-CUR support CAN FD according to ISO 16845-1:2016?
No, the ATSAMA5D22B-CUR implements MCAN controllers using the non-ISO CAN FD frame format and does not pass the official CAN FD Conformance Test per ISO 16845-1:2016. While it supports CAN FD data rates up to 5 Mbps and features SRAM-based mailboxes and time-triggered transmission, designers must verify interoperability with ISO-compliant nodes in their specific network topology and may require protocol translation layers for full standards compliance.
Which package type is used for the ATSAMA5D22B-CUR?
The ATSAMA5D22B-CUR uses a 256-ball Thin Fine-Pitch Ball Grid Array (TFBGA) package measuring 8 mm × 8 mm with 0.4 mm ball pitch and 1.05 mm thickness. This package is distinct from the 196-ball TFBGA (SAMA5D23) and 289-ball LFBGA (SAMA5D27), and is validated for extended industrial temperature operation from −40°C to +105°C ambient.
What security features are implemented in hardware on the ATSAMA5D22B-CUR?
The ATSAMA5D22B-CUR integrates multiple hardware security features: Arm TrustZone for memory/peripheral isolation, 5-Kbyte scrambled SRAM (1-Kbyte nonerasable on tamper), 8 dedicated tamper detection pins (PIOBU0–PIOBU7), Integrity Check Monitor (ICM) with SHA256, AESB bridge for on-the-fly DDR/QSPI encryption, and FIPS-compliant AES/SHA/TRNG crypto accelerators. These features collectively enable secure boot, runtime memory integrity verification, and protection against physical intrusion and firmware cloning.
Can the ATSAMA5D22B-CUR run Linux operating systems?
Yes, the ATSAMA5D22B-CUR is fully qualified to run Linux distributions, including Microchip's officially supported Yocto Project-based Linux BSP. Its Arm Cortex-A5 core with MMU, 32-Kbyte L1 caches, 128-Kbyte configurable L2 cache, and support for DDR2/DDR3L/LPDDR2/LPDDR3 memory make it suitable for full-featured embedded Linux deployments. Microchip provides free Linux distribution packages, device tree support, and bare-metal C examples for rapid development.
