ATSAMA5D22A-CUR Übersicht
An MPU (microprocessor unit) is a system-on-chip category that integrates a CPU core, memory controller, peripherals, and optional accelerators onto a single die. Within the broader taxonomy, the ATSAMA5D22A-CUR sits under ARM Cortex-A application processors -> microprocessor unit -> integrated circuit. MPUs typically run Linux or other high-level operating systems, distinguishing them from microcontrollers (MCUs) which run bare-metal or RTOS firmware. The Cortex-A5 core implements the ARMv7-A architecture with TrustZone security extensions and a Memory Management Unit (MMU) for full virtual-memory operating systems such as Linux.
Key features include a Peripheral Touch Controller (PTC), embedded audio subsystem with I2S and Class D amplifier support, dual EMAC Ethernet, two HSIC USB ports, three HS/FS USB ports, two CAN-FD controllers, hardware AES-OTF (on-the-fly) encryption engine, 0.8 mm ball-pitch BGA package that simplifies PCB layout, and a simple power-management scheme. The SAMA5D2 architecture achieves ultra-low standby power of approximately 5 uA in backup mode with retention, enabling battery-backed designs that must survive months on a single cell.
Typical applications include HMI (human-machine interface) panels, IoT edge gateways, smart-home controllers, building-automation bridges, industrial-control HMIs, and connected medical devices. The on-chip graphics accelerator plus LCD controller supports up to WXGA (1280x768) displays without external graphics silicon, while the AES engine and secure-boot ROM simplify connected-product security.
When designing with this MPN, ensure the PCB uses 0.8 mm-pitch micro-via BGA fan-out routing and that the DDR interface is length-matched within the JEDEC JESD79 DDR specification. The 11x11 mm TFBGA has 196 balls on 0.8 mm pitch, so blind or buried vias are typically required for escape routing on a 4-layer board. Linux BSP support is available through the mainline kernel and Microchip's at91bootstrap bootloader, with mainline Device Tree bindings for all on-chip peripherals.

ATSAMA5D22A-CUR ist geeignet für 6 Anwendungs: Industrial HMI Panels, IoT Edge Gateways, Smart Home Controllers, Building Automation Bridges, Connected Medical Devices, Industrial Control / CAN Gateways.
Industrial HMI Panels
The ATSAMA5D22A-CUR's 500 MHz Cortex-A5 core, integrated WXGA LCD controller, and 2D graphics accelerator make it well-suited for industrial HMI panels running Linux with Qt or Web-based UIs. The on-chip LCD controller drives resolutions up to 1280x768 without external graphics silicon, lowering BOM cost. Two EMAC ports support redundant industrial Ethernet, while 2x CAN-FD enables connectivity to field-bus devices. The 105 C industrial temperature rating qualifies the part for factory-floor enclosures.

Designhinweise
Estimated: the 196-TFBGA at 0.8 mm ball pitch requires micro-via (laser-drilled) stack-ups to escape the inner-row balls on a 4-layer PCB. Use a 1-2-1 build with 0.2 mm via-pad diameter and 0.1 mm drill; avoid dog-bone fan-outs where possible because the 0.8 mm pitch is borderline for standard 0.3 mm-pitch vias. Reference Microchip's SAMA5D2 hardware design guide for length-matched DDR routing within the JEDEC JESD79 specification.
Estimated: at 500 MHz with all peripherals active, the ATSAMA5D22A-CUR dissipates approximately 0.5-1.0 W depending on DDR traffic and graphics load. The 196-TFBGA exposes a thermal pad through the central ball array; stitch thermal vias (0.3 mm drill, 1.0 mm pitch) to an inner copper pour to keep junction temperature below 125 C at the 105 C industrial ambient. Without thermal vias, expect a 10-15 C rise in junction temperature versus a properly stitched design.
The SAMA5D2 power tree requires at least three rails (VDDCORE ~1.0-1.2 V, VDDPLL, VDDIO at 1.8 V or 3.3 V) plus separate VDDBU for backup domain. Decouple each rail with 100 nF X7R ceramic placed within 2 mm of the supply pin, plus a bulk 10 uF per rail. The backup-mode 5 uA figure is only achievable with the slow-clock domain properly configured in the PMC; verify with the SAMA5D2 power-management chapter before claiming battery-life numbers.
Do not assume the ATSAMA5D22A-CUR is a microcontroller - it is an MPU with MMU and runs Linux; bare-metal code paths that work on Cortex-M parts will not port directly. JTAG/SWD use the chip's 4-wire debug port; configure bootstrap pins correctly for boot-from-SPI vs boot-from-e.MMC. The DDR calibration routine in at91bootstrap must run on every cold boot, or boot reliability will degrade in production.
Compliance-Informationen
RoHS and lead-free per Microchip product page. Not AEC-Q100 qualified - this is an industrial MPU, not an automotive grade; choose ATSAMA5D2xA-MVA grade for AEC-Q100 applications.
