Product details
Overview
ATSAMA5D22A-CUR from Microchip Technology is an ultra-low-power Arm Cortex-A5-based microprocessor unit (MPU) operating at up to 500 MHz, featuring integrated DDR2/DDR3L/LPDDR2/LPDDR3 memory controller, 10/100 Ethernet MAC (GMAC), dual CAN-FD controllers, USB high-speed host/device ports, and hardware crypto accelerators (AES-256, SHA-256, TRNG). It targets secure industrial HMI, IoT gateway, and point-of-sale terminals requiring real-time connectivity and tamper-resistant firmware execution.
For engineers reviewing the ATSAMA5D22A-CUR datasheet, ATSAMA5D22A-CUR pinout, ATSAMA5D22A-CUR application, or ATSAMA5D22A-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 CAN-FD, 5 UARTs, 2 QSPI, 12-bit ADC with touchscreen), and two documented alternative MPUs for design flexibility.
Technical Context
The ATSAMA5D22A-CUR implements an Armv7-A architecture Cortex-A5 core with TrustZone security, NEON SIMD engine, and floating-point unit (FPU), paired with a 32-KB L1 instruction cache, 32-KB L1 data cache, and configurable 128-KB L2 cache usable as SRAM. Its multilayer bus architecture supports concurrent high-bandwidth transfers via two 16-channel DMA controllers and dedicated peripheral DMAs.
It integrates dual MCAN controllers compliant with non-ISO CAN FD frame format (not ISO 16845-1:2016 conformant), a 10/100 Ethernet MAC with IEEE 802.1AS timestamping and 802.1Qav traffic shaping, and a 12-channel 12-bit ADC with resistive touchscreen support. Security is enforced via on-the-fly AES encryption/decryption of DDR and QSPI memories, 5-KB scrambled secure SRAM, eight tamper-detection pins (PIOBU0–7), and Integrity Check Monitor (ICM) using SHA-256.

FAQ
What is the maximum operating frequency of the ATSAMA5D22A-CUR?
The ATSAMA5D22A-CUR operates at up to 500 MHz on its Arm Cortex-A5 core. This frequency is achievable under typical conditions with appropriate voltage scaling and thermal management. The device also supports lower-frequency operation in ultra-low-power modes, such as ULP0 (512 Hz system clock) and ULP1 (all clocks stopped), to minimize energy consumption during idle periods. ATSAMA5D22A-CUR maintains full peripheral functionality at reduced frequencies where applicable.
Does the ATSAMA5D22A-CUR support ISO 16845-1:2016 CAN FD conformance testing?
No, the ATSAMA5D22A-CUR implements MCAN controllers using the non-ISO CAN FD frame format and therefore does not pass the CAN FD Conformance Test according to ISO 16845-1:2016. This is explicitly documented in the official datasheet. ATSAMA5D22A-CUR remains suitable for applications requiring CAN FD data rates and flexible DLC, but system-level compliance validation must account for this deviation from the ISO standard.
Which package type is used by the ATSAMA5D22A-CUR?
The ATSAMA5D22A-CUR uses a 256-ball thin fine-pitch ball grid array (TFBGA) package measuring 8 mm × 8 mm with 0.4 mm pitch and 1.05 mm thickness. This package is qualified for extended industrial temperature operation (−40°C to +105°C) and provides 105 user-accessible I/O pins. It is distinct from the 196-ball and 289-ball variants used by other SAMA5D2 family members.
What security features are integrated into the ATSAMA5D22A-CUR?
The ATSAMA5D22A-CUR includes hardware-enforced security features: Arm TrustZone, 5-KB scrambled secure SRAM (1 KB nonerasable on tamper), eight tamper-detection pins (PIOBU0–7), Integrity Check Monitor (ICM) using SHA-256, on-the-fly AES encryption/decryption of DDR and QSPI memories, and a secure bootloader in 64-KB ROM. These features collectively support secure boot, runtime firmware protection, and physical intrusion response. ATSAMA5D22A-CUR is designed for applications requiring anti-cloning and data confidentiality.
Can the ATSAMA5D22A-CUR run Linux out of the box?
Yes, the ATSAMA5D22A-CUR is delivered with a free Linux distribution and bare metal C examples from Microchip. Its memory management unit (MMU), 32-KB L1 caches, configurable 128-KB L2 cache, and DDR memory controller fully support mainstream Linux kernels. Pre-verified BSPs, device tree files, and Yocto Project layers are available for rapid development of production-grade embedded Linux systems. ATSAMA5D22A-CUR has been validated for use with Linux in industrial and IoT reference designs.
