ATSAMA5D4-EK 概要
An ARM Cortex-A5 MPU is a 32-bit application-class processor based on the ARMv7-A architecture that supports full operating systems such as Linux and Android. It sits hierarchically within MPU (microprocessor unit) -> application processor -> SoC -> semiconductor, providing much higher computational throughput than Cortex-M microcontrollers while retaining deterministic interrupt response through the NEON media engine for SIMD-accelerated codecs, image processing, and DSP workloads.
Key features of the ATSAMA5D4-EK include a 600 MHz Cortex-A5 core with NEON, 128 KB L2 cache, FPU, on-board DDR2/LPDDR2 memory expansion, an LCD interface with maXTouch support, HDMI output, two Ethernet ports, USB host/device, SD card storage, and a JTAG/SWD debug interface. The integrated peripherals are exposed through MikroElektronika-style headers, an Arduino R3-compatible shield interface, and the Xplained extension connector for rapid prototyping of HMI and connectivity-rich applications.
From an architectural perspective, the ATSAMA5D44 silicon combines the application-class Cortex-A5 cluster with a dedicated system-bus matrix, a graphics LCD controller (LCDC) with overlays for video pipelines, a high-speed USB 2.0 OTG controller, and a sophisticated power-management unit (PMU) that supports low-power standby modes. The board exposes these buses through the Xplained Ultra-style headers so engineers can reuse the same physical interface for industrial gateways, smart appliances, and connected medical devices.
Typical applications include Linux-based human-machine interface (HMI) panels, industrial IoT gateways, smart-home control panels, point-of-sale terminals, machine-vision edge nodes, and audio/video streaming appliances. The board is a drop-in reference design used by OEMs to validate their custom SAMA5D4 carrier boards before tape-out, accelerating time-to-market for ultra-low-power Cortex-A5 products.
When designing with this kit, pay close attention to the on-board DDR2/LPDDR2 routing topology and length matching, since signal integrity at 200 MHz memory clock is critical for Linux boot stability. Use the supplied AT91Bootstrap, U-Boot, and Linux4SAM distribution images from the manufacturer website to avoid pin-mux conflicts during initial bring-up.

主な用途
ATSAMA5D4-EK の用途: 7 件s: Linux-based HMI Touch Panels, Industrial IoT Gateways, Smart Home Control Panels, Point-of-Sale Terminals, Machine Vision Edge Nodes, Connected Medical Devices, Audio/Video Streaming Appliances.
Linux-based HMI Touch Panels
The ATSAMA5D4-EK is purpose-built for industrial human-machine interface (HMI) touch panels where a 600 MHz Cortex-A5 with NEON SIMD and a 128 KB L2 cache provides enough headroom for Qt/Embedded, LVGL, or WebKit-based graphics stacks. Its integrated LCD controller with maXTouch support directly drives capacitive touchscreens, while the HDMI output enables dual-display designs for retail and factory automation. Designers can validate their UI stack on this reference platform before committing to a custom carrier, shortening HMI time-to-market by several months.
おすすめ
Industrial IoT Gateways
For industrial IoT gateways that aggregate Modbus/TCP, OPC-UA, MQTT, and BACnet traffic at the edge, the ATSAMA5D4-EK's 600 MHz Cortex-A5 with floating-point unit handles encryption (TLS/DTLS), JSON/XML parsing, and lightweight database operations without skipping real-time cycles. The board's Gigabit Ethernet and dual USB 2.0 ports accommodate cellular modems, Wi-Fi modules, and RS-485 adapters, while the DDR2/LPDDR2 interface keeps memory bandwidth high enough for cloud protocol buffering.
おすすめ
Smart Home Control Panels
Smart-home control panels benefit from the ATSAMA5D4-EK's combination of low-power Cortex-A5 cores, LCD with capacitive touch, and rich connectivity. The kit runs Linux4SAM and Matter/Thread stacks, while its HDMI and LCD outputs let integrators prototype wall-mounted touch controllers that orchestrate lighting, HVAC, and security subsystems. The NEON engine accelerates on-device voice wake-word and acoustic-event detection, allowing the panel to act as both UI and always-on listening node.
おすすめ
Point-of-Sale Terminals
Point-of-sale (POS) terminals require cryptographic performance, reliable touch input, and multiple I/O options for barcode scanners, receipt printers, and NFC readers. The ATSAMA5D4-EK's 600 MHz Cortex-A5 plus NEON accelerates AES/SHA primitives used by EMV and PCI-PTS transactions, while the LCD with maXTouch delivers the responsive customer-facing display. The kit's USB OTG and SD/MMC storage accommodate firmware updates and audit-log retention required by retail payment certification.
おすすめ
Machine Vision Edge Nodes
For machine-vision edge nodes that perform barcode reading, optical inspection, or simple object recognition at line speed, the ATSAMA5D4-EK's Cortex-A5 with NEON SIMD delivers measurable OpenCV acceleration versus Cortex-M microcontrollers. The board's HDMI output streams inspection images to a local monitor, and the Gigabit Ethernet forwards only metadata and pass/fail decisions upstream. This keeps network bandwidth low while still benefiting from on-device image processing latency under 50 ms.
おすすめ
Connected Medical Devices
Connected medical devices such as patient monitors, infusion pumps, and diagnostic kiosks benefit from the ATSAMA5D4-EK's deterministic interrupt response and full Linux OS support for FDA/IEC 62304 software life-cycle documentation. The kit's isolated USB and Ethernet ports ease IEC 60601-1 compliance work, while the LCD with capacitive touch delivers the high-contrast UI clinicians expect. The Cortex-A5 + FPU runs signal-processing algorithms for ECG, SpO2, and capnography without offloading to a separate DSP.
おすすめ
Audio/Video Streaming Appliances
Audio/video streaming appliances that decode H.264 or VP8 streams for digital signage or in-vehicle infotainment benefit from the ATSAMA5D4-EK's NEON SIMD engine and hardware-accelerated video pipelines. The HDMI output drives external displays, while the LCD interface supports an integrated control panel. With DDR2/LPDDR2 bandwidth headroom and GbE throughput, the kit serves as a reference for low-cost signage players and kiosks where Linux SDK availability matters.

設計ノート
The ATSAMA5D4-EK is designed for the commercial 0-70 C ambient range when operated with the on-board DDR2/LPDDR2 memory populated. Estimated: at full 600 MHz Cortex-A5 utilization with HDMI and GbE active, the silicon dissipates approximately 1.5 W; the EK board exposes a thermal pad under the MPU and a heatsink footprint, so engineers porting to a custom carrier should preserve at least 4-layer PCB copper pour (1 oz, 2 sq in) under the BGA to stay within the 85 C junction rating for industrial-grade variants like ATSAMA5D44A-CUR.
DDR2/LPDDR2 traces on the EK reference design are length-matched to within 25 mil across the byte lanes, with reference planes on layers 2 and 4. Estimated: replicating this topology on a custom carrier requires layer-by-layer impedance control of 50 ohm single-ended and 100 ohm differential, plus series-termination resistors on the clock pair. Skipping these rules typically results in Linux boot failures that manifest as U-Boot 'DRAM not recognized' errors.
The EK board uses an Arduino R3-compatible shield interface plus a MikroElektronika click-board socket, both of which share GPIO lines with the LCD controller. Estimated: stacking a click-board that reassigns those pins without checking the pin-mux table in the ATSAMA5D44 datasheet will silently disable the maXTouch interrupt and freeze the touch UI. Always grep the Linux device tree (at91-sama5d4ek.dts) before adding expansion boards.
The HDMI output on the EK uses an ADV7511 transmitter reference design with controlled-impedance 100 ohm differential pairs routed over an unbroken ground plane. Estimated: keep-out zones of 5 mm around the HDMI connector are required to pass HDMI 1.4 compliance eye-pattern tests; placing a switching regulator or noisy GPIO trace within that keep-out will degrade the TMDS eye to the point of failing sink-device authentication on certain monitors.
The Gigabit Ethernet PHY on the EK uses the KSZ9031RNX with RGMII traces length-matched to within 50 mil. Estimated: when porting to a custom board, route the RGMII clock with 50 ohm controlled impedance and source termination within 5 mm of the MPU ball; otherwise CRC errors will appear under heavy TCP load and are notoriously hard to diagnose without an oscilloscope and BERT pattern generator.
