Product details
Overview
ATSAMA5D22B-CNR from Microchip Technology is an ultra-low-power Arm Cortex-A5-based microprocessor unit (MPU) operating at up to 500 MHz, featuring a 16-bit DDR bus, 105 GPIOs, dual CAN-FD controllers, 10/100 Ethernet MAC (GMAC), and hardware crypto acceleration (AES-256, SHA-256, TRNG). It targets secure industrial HMI, IoT gateways, and point-of-sale terminals requiring Linux support, tamper-resistant boot, and extended temperature operation (-40°C to +105°C).
For engineers reviewing the ATSAMA5D22B-CNR datasheet, ATSAMA5D22B-CNR pinout, ATSAMA5D22B-CNR application, or ATSAMA5D22B-CNR 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), real-world peripheral integration (ISC, LCDC, SDMMC), and two rigorously validated alternative MPUs for functional migration paths.
Technical Context
The ATSAMA5D22B-CNR implements an Armv7-A architecture with TrustZone security, NEON SIMD engine, and floating-point unit (FPU), enabling deterministic real-time processing in Linux environments. Its memory subsystem includes 32-KB L1 instruction/data caches, configurable 128-KB L2 cache (usable as SRAM), and a high-bandwidth 16-bit DDR controller supporting DDR3L/LPDDR2/LPDDR3 with on-the-fly AES encryption.
System-level features include dual MCAN controllers compliant with non-ISO CAN FD frame format, IEEE 802.1AS timestamping for AVB Ethernet, and a dedicated Event System allowing peripherals to exchange signals without CPU intervention in Active or Idle mode. Security is enforced via 5-KB scrambled SRAM (1-KB nonerasable on tamper), Integrity Check Monitor (ICM), and secure bootloader with fuse-based JTAG protection.

FAQ
What is the maximum supported DDR memory configuration for ATSAMA5D22B-CNR?
The ATSAMA5D22B-CNR supports up to 512 Mbytes of DDR2, DDR3, DDR3L, LPDDR1, LPDDR2, or LPDDR3 memory via its 16-bit DDR controller. It operates with DLL-off timing only for DDR3/DDR3L and includes on-the-fly AES encryption/decryption for DDR and QSPI memories using the AESB module. The controller also supports "on-the-fly" scrambling and ECC for enhanced data integrity.
Does ATSAMA5D22B-CNR support IEEE 1588 Precision Time Protocol?
Yes, ATSAMA5D22B-CNR integrates IEEE 1588 Precision Time Protocol (PTP) support within its GMAC peripheral. It provides hardware timestamping for both transmit and receive packets, along with IEEE 802.1AS timestamping for Audio Video Bridging (AVB) compliance. This enables sub-microsecond synchronization accuracy in time-sensitive industrial networking applications without CPU intervention.
How does ATSAMA5D22B-CNR implement tamper detection and response?
ATSAMA5D22B-CNR features up to eight dedicated tamper pins (PIOBU0–PIOBU7) supporting static or dynamic intrusion detection. Upon tamper event, 1 Kbyte of internal scrambled SRAM becomes nonerasable and 4 Kbytes is erased. The device also includes environmental monitors (temperature, voltage, frequency) and an active die shield on select versions. RTC logs intrusion timestamps, and the fuse box (544 bits) enables permanent JTAG disable.
What power management ICs are recommended for ATSAMA5D22B-CNR?
Microchip recommends the MCP16502AA and MCP16501A PMICs for ATSAMA5D22B-CNR. Both provide pin-selectable VDDIODDR (1.2 V / 1.35 V / 1.8 V) to match DDR3L/LPDDR2/LPDDR3 requirements, leakage-free I²C control in all power modes, and dedicated rails for VDDCORE, VDDIO, and VDDFUSE. The MCP16502AA supports four DC-DC converters; the MCP16501A offers three in a 4×4 mm QFN24 package.
Is ATSAMA5D22B-CNR compatible with Linux distributions out of the box?
Yes, ATSAMA5D22B-CNR is delivered with a free, production-ready Linux distribution from Microchip, including kernel drivers, device tree support, Yocto Project integration, and bare-metal C examples. The MPU's MMU, 32-KB L1 caches, and 128-KB configurable L2 cache ensure efficient Linux execution, while the secure bootloader validates signed images during boot, enabling trusted execution environments.
