ATSAMA5D43B-CU 概要
What is an ARM Cortex-A5 microprocessor? An ARM Cortex-A5 is a 32-bit application-class processor core implementing the ARMv7-A architecture. It sits in the Cortex-A family hierarchy (A5 < A7 < A8 < A9 < A15) as the entry-level application core, above microcontroller-class Cortex-M cores. Microprocessors in the SAMA5 family target Linux- and Android-capable human-machine interface (HMI) and edge-node applications, where a Cortex-A5 supplies more compute than a Cortex-M and lower cost/power than a Cortex-A7/A9.
Key features of the ATSAMA5D43B-CU include ARM Cortex-A5 core running at up to 600 MHz with NEON media engine, hardware floating-point (VFPv4), 32 KB I-cache and 32 KB D-cache with MMU, integrated TFT LCD controller up to WVGA (2048x2048 max), built-in 10/100 Ethernet MAC with GMII/RGMII/MII interface, three USB 2.0 high-speed ports, image sensor interface (ISI), CAN, I2S audio, SD/MMC, NAND/NOR flash controllers, and a security subsystem with secure boot and hardware crypto accelerators (AES, SHA, TRNG).
Architecturally, the SAMA5D43B silicon uses a 65 nm low-power CMOS process. The core operates from a 1.2 V internal rail, the memory interface from 1.2/1.8/3.3 V, and most I/O from 3.3 V. Per Microchip documentation, the device draws roughly 200 mA active at 600 MHz and supports deep-sleep modes drawing under 1 mA, making it suitable for fanless industrial designs with proper thermal management.
Typical applications for the ATSAMA5D43B-CU include industrial HMI panels, building automation gateways, smart energy concentrators, medical patient-interface displays, and ruggedized handheld terminals. The integrated display, touchscreen, and Ethernet make it well suited for Linux-driven HMI, while the secure-boot and crypto engines support payment- and access-control appliances.
When designing with this MPU, allocate four-layer PCB stack-up with continuous GND planes under the BGA to provide both return paths and thermal dissipation, and follow Microchip's SAMA5D4 hardware design checklist for DDR2/LPDDR signal routing. Ensure proper decoupling per the reference schematic and validate boot media (NAND/SD/eMMC) against the BSP you intend to use (mainline Linux, Buildroot, or Microchip's AT91 distribution).

主な用途
ATSAMA5D43B-CU の用途: 6 件s: Industrial HMI Panels, Building Automation Gateways, Medical Patient-Interface Displays, Smart Energy Concentrators, Ruggedized Handheld Terminals, Secure Payment Terminals.
Industrial HMI Panels
The ATSAMA5D43B-CU is purpose-built for industrial HMI panels requiring a Linux-capable Cortex-A5 core with integrated graphics and touchscreen support. Its integrated WVGA-class LCD controller with hardware 2D acceleration drives TFT displays up to 2048x2048, while the 600 MHz ARM Cortex-A5 with NEON handles Qt/GTK framebuffers smoothly. The 10/100 Ethernet MAC enables real-time Modbus/TCP, EtherNet/IP, or PROFINET connectivity, and the industrial -40C to +85C temperature grade supports factory-floor deployment. Three USB 2.0 ports (one HSIC) allow barcode scanners, RFID readers, and external storage simultaneously. The 128 KB on-chip ROM enables secure-boot flows required in IIoT gateways.
おすすめ
Building Automation Gateways
In building-automation gateways, the ATSAMA5D43B-CU runs Linux with BACnet, KNX, or LonWorks stacks, aggregating data from HVAC, lighting, and access-control subsystems. The hardware crypto engine (AES, SHA, TRNG) supports TLS 1.3 termination for cloud connectivity, while secure-boot prevents firmware tampering. The 10/100 Ethernet MAC and three USB 2.0 ports provide multiple physical interfaces, and the CAN bus peripheral integrates with industrial HVAC equipment. Deep-sleep modes below 1 mA allow the gateway to remain network-responsive while reducing energy bills by 30-50% versus always-on designs.
おすすめ
Medical Patient-Interface Displays
Medical patient-interface displays benefit from the ATSAMA5D43B-CU's integrated touchscreen controller, hardware encryption, and long-life industrial temperature support. The Cortex-A5 at 600 MHz drives Qt-based UIs for infusion pumps, patient monitors, and diagnostic terminals while consuming under 250 mW active. The image-sensor interface (ISI) allows direct connection to a camera for telemedicine endpoints. Hardware secure-boot and AES/SHA accelerators meet FDA cybersecurity premarket guidance. The 289-LFBGA package enables compact 5-inch handheld form factors with single-board layouts.
おすすめ
Smart Energy Concentrators
Smart energy concentrators aggregate data from electricity, water, and gas meters over M-Bus, Wireless M-Bus, or PLC links. The ATSAMA5D43B-CU runs DLMS/COSEM stacks on Linux with its 600 MHz Cortex-A5 and 128 KB on-chip SRAM boot ROM. The hardware crypto accelerator handles TLS and DTLS handshakes required for AMI backhaul to utility head-end systems. Industrial temperature rating and LFBGA packaging suit outdoor meter-data concentrator enclosures. The three USB 2.0 ports and Ethernet MAC allow redundant WAN paths (cellular modem + Ethernet).
おすすめ
Ruggedized Handheld Terminals
Ruggedized handheld terminals - used in warehouses, field service, and logistics - leverage the ATSAMA5D43B-CU's low-power deep-sleep modes, industrial temperature range, and integrated peripherals. The image-sensor interface connects directly to a barcode/2D imager, while the LCD controller drives 4-7 inch sunlight-readable displays. Three USB 2.0 ports support charging cradles, RFID readers, and Wi-Fi dongles. Hardware encryption and secure-boot protect sensitive shipment data. The 289-LFBGA enables a slim handheld PCB less than 80x140 mm with BGA-internal routing only.
おすすめ
Secure Payment Terminals
POS and payment terminals benefit from the ATSAMA5D43B-CU's hardware secure-boot chain, AES/SHA accelerators, and tamper-resistant boot ROM. The 600 MHz Cortex-A5 runs Android or Linux payment applications with PCI PTS 5.x certified firmware stacks. Integrated LCD and touchscreen support drive signature-capture displays, while the image-sensor interface attaches to camera modules for QR-code payment flows. The 10/100 Ethernet plus three USB 2.0 ports support chip-card readers, NFC modules, and receipt printers simultaneously. Hardware TRNG meets payment-industry cryptographic randomness requirements.

- In-family lower-speed migration path （vs ATSAMA5D42B-CU)
設計ノート
Use a 4-layer PCB stack-up with continuous GND planes directly beneath the 289-LFBGA footprint. Route DDR2/LPDDR signals on the top layer with reference to inner GND, keep matched lengths within 25 mil (0.635 mm), and use 100-ohm differential impedance for HSIC. Place eight 100 nF + four 4.7 uF decoupling capacitors within 5 mm of the BGA balls, distributed around the four BGA quadrants per Microchip's SAMA5D4 hardware design checklist.
Estimated: At 600 MHz active with VDDCORE at 1.2 V drawing ~200 mA (~240 mW) plus DDR2 I/O, total dissipation is roughly 400-500 mW. The 289-LFBGA's typical theta_JA of ~28 C/W on a 4-layer JEDEC board yields a junction-to-ambient rise of about 14C - well within industrial limits - but in sealed enclosures with no airflow, derate clock speed or add a small copper-pour heatsink. Use the SAMA5D4 BSDL/JTAG thermal diode for production testing.
Do not omit the external 32.768 kHz low-frequency crystal on the SAMA5D4 - it is required for the RTC, deep-sleep wakeup timers, and slow-clock domains. Do not boot from SD card without setting the BMS (Boot Mode Select) pins correctly via external pull resistors - the B-silicon revision defaults to NAND boot. Verify that the 1.2 V core regulator has at least 500 mA capacity and 3% accuracy across load transients to avoid LFSR errors during DDR2 training.
