Product details
Overview
ATSAMA5D22A-CU from Microchip Technology is an ultra-low-power Arm Cortex-A5-based microprocessor unit (MPU) operating at up to 500 MHz, integrating DDR3L/LPDDR2/LPDDR3 memory controllers, 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 delivers secure embedded computing for industrial HMI, IoT gateways, and point-of-sale terminals requiring real-time connectivity and tamper-resistant firmware execution.
For engineers reviewing the ATSAMA5D22A-CU datasheet, ATSAMA5D22A-CU pinout, ATSAMA5D22A-CU application, or ATSAMA5D22A-CU equivalent, this page provides 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, 10 UARTs, 12-channel 12-bit ADC), and two field-validated alternative MPUs with documented functional trade-offs.
Technical Context
The ATSAMA5D22A-CU 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 2 × 16-channel DMA controllers for zero-overhead peripheral data transfers.
It integrates a dedicated security subsystem including 5 KB scrambled SRAM (1 KB nonerasable on tamper), 8 tamper detection pins (PIOBU0–7), Integrity Check Monitor (ICM) with SHA-256, on-the-fly AES encryption/decryption for DDR and QSPI, and a secure bootloader in 64-KB masked ROM. The device supports IEEE 802.1AS timestamping, AVB traffic shaping (IEEE 802.1Qav), and PTP v2 for deterministic networking.

Equivalent & Alternatives
The following parts are listed as comparable options for similar MPU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATSAMA5D27A-CU | 289-ball LFBGA, 128 GPIOs, dual CAN-FD, 2× QSPI, 2× SDMMC, extended environmental monitors (temp/voltage/frequency) | Required for designs needing >105 I/Os, dual SD card slots, or die-level environmental monitoring for safety-critical certification | Select when board layout allows larger 14×14 mm package and application demands enhanced tamper resilience or wider I/O expansion |
| i.MX6ULL | Arm Cortex-A7 @ 900 MHz, single-core, no TrustZone, no hardware AES/SHA, 1× CAN, no tamper pins, 14x14 mm 289-BGA | Suitable for cost-sensitive Linux applications without cryptographic acceleration or physical security requirements | Choose only if AES/SHA/TRNG, tamper detection, or TrustZone isolation are not required - lacks IEC 60730 Class B safety features present in ATSAMA5D22A-CU |
Compared with ATSAMA5D22A-CU, ATSAMA5D27A-CU adds environmental monitoring and I/O headroom but increases footprint and cost; i.MX6ULL offers higher CPU clock but omits all hardware security accelerators, tamper detection, and safety diagnostics - making it unsuitable for certified POS or industrial safety applications.

FAQ
What is the maximum operating frequency of the ATSAMA5D22A-CU?
The ATSAMA5D22A-CU operates at up to 500 MHz on its Arm Cortex-A5 core. This frequency is sustained under typical industrial conditions with appropriate power delivery and thermal management. The device also includes a 600–1200 MHz system PLL and a dedicated 480 MHz USB PLL to support high-speed peripheral operation without core clock dependency.
Does the ATSAMA5D22A-CU support DDR3L memory?
Yes, the ATSAMA5D22A-CU supports DDR3L memory via its high-bandwidth 16-bit DDR controller, which is explicitly qualified for DDR3L operation at 1.35 V. The controller supports DLL-off mode only and includes on-the-fly AES encryption/decryption (AESB) for secure data handling in external memory.
How many CAN-FD interfaces does the ATSAMA5D22A-CU provide?
The ATSAMA5D22A-CU integrates two host CAN-FD (MCAN) controllers, each with SRAM-based mailboxes and support for time- and event-triggered transmission. These controllers implement the non-ISO CAN FD frame format and do not pass ISO 16845-1:2016 conformance testing - a documented limitation per Microchip's datasheet.
What security features are implemented in hardware on the ATSAMA5D22A-CU?
The ATSAMA5D22A-CU includes hardware AES-256/192/128, SHA-1/224/256/384/512, TDES, and TRNG compliant with NIST SP 800-22. It also features 5 KB of tamper-responsive scrambled SRAM, 8 dedicated tamper pins (PIOBU0–7), Integrity Check Monitor (ICM), secure bootloader in masked ROM, and TrustZone-enabled memory/peripheral isolation.
Which package type is used for the ATSAMA5D22A-CU?
The ATSAMA5D22A-CU 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 rated for industrial temperature range (-40°C to +105°C) and is pin-compatible with other SAMA5D22 variants in the same footprint.
