ATSAMA5D43A-CUR Übersicht
An ARM Cortex-A5 microprocessor (MPU) is a high-performance 32-bit application-class processor core built on the ARMv7-A architecture. Within the broader taxonomy, the Cortex-A5 sits inside the Cortex-A series -> ARM application-class CPUs -> 32-bit RISC processors -> microprocessors -> integrated circuits. MPUs differ from microcontrollers (MCUs) by lacking on-chip flash, instead booting from external DDR/NAND/NOR memory, which makes them well-suited to Linux and other rich-OS workloads that exceed the memory capacity of typical MCUs.
Key features of the ATSAMA5D43A-CUR include an ARM Cortex-A5 core with NEON, a 2D graphics accelerator, hardware video decoder for H.264 / MPEG-4 / MPEG-2 / VC-1, a 24-bit LCD controller with overlays, dual EMAC for Gigabit Ethernet, two High-Speed USB 2.0 ports (one Host, one OTG), and multiple connectivity options including CAN, UART, SPI, I2C, I2S, and SDIO. It supports up to 1 GB of DDR2/LPDDR/LPDDR2 memory through a 16-bit external bus and operates from a 3.3 V core/IO supply with internal LDO regulators.
Architecture-wise, the SAMA5D4 series combines the Cortex-A5 core with dedicated multimedia IP blocks, allowing simultaneous video decode and LCD composition without loading the CPU. The high-bandwidth multi-layer bus matrix gives the LCD controller and the CPU concurrent access to DDR, which prevents display tearing in WVGA-class human-machine interfaces (HMIs).
Typical applications include industrial HMI panels, home automation gateways, medical patient monitors, point-of-sale terminals, smart energy gateways, and ruggedized portable data terminals. The on-chip video decoder and LCD controller make it particularly attractive for products that must drive a large color display and decode a camera or video stream in parallel.
When designing with the ATSAMA5D43A-CUR, plan the PCB layout around the 289-ball LFBGA; this package has a 0.8 mm pitch and demands at least 4-layer routing with buried vias for reliable manufacturing. Use the Microchip SAMA5D4 Software Package (at91bootstrap, U-Boot, Linux mainline) and the ATSAMA5D4-XULT or AC320005-5 development kits as reference designs.

Typische Anwendungen
ATSAMA5D43A-CUR ist geeignet für 7 Anwendungs: Industrial HMI Touch Panels, Smart Home / Building Automation Gateways, Medical Patient Monitoring Terminals, Point-of-Sale (POS) Terminals, Industrial Printer Control Boards, Smart Energy Gateways and Sub-Station RTUs, Ruggedized Handheld Data Terminals.
Industrial HMI Touch Panels
The ATSAMA5D43A-CUR drives 5-inch to 7-inch WVGA industrial HMI panels by combining the on-die maXTouch controller with the 24-bit LCD controller and 2D graphics accelerator. With a 600 MHz Cortex-A5 plus NEON, the part handles LVGL/Qt GUI rendering at 60 fps while leaving CPU headroom for EtherCAT slave, PROFINET, or Modbus TCP industrial Ethernet protocols on the dual GMAC. Reference design AC320005-5 + ATSAMA5D4-XULT gives a known-good BOM for panel builders. Operating temperature -40C to +85C covers factory floor enclosures without conformal coating rework.

Smart Home / Building Automation Gateways
As a gateway hub, the ATSAMA5D43A-CUR aggregates Zigbee, Z-Wave, KNX, and Wi-Fi sub-systems through its USB 2.0, SDIO, and UART/SPI/I2C interfaces, then exposes a unified cloud API over the dual Gigabit EMAC. The 600 MHz core runs OpenWrt or Buildroot Linux with full mainline support, while the 128 KB on-chip ROM houses the secure bootloader for signed firmware update. Hardware video decode lets the same gateway drive a wall-mounted touch display, removing the need for a separate panel processor and reducing BOM cost by roughly $5-10 per unit.

Medical Patient Monitoring Terminals
The ATSAMA5D43A-CUR powers bedside patient monitors by processing multi-lead ECG, SpO2, and NIBP waveforms through its NEON-accelerated DSP libraries, then rendering the waveforms in real time on the 24-bit LCD with maXTouch overlay. The 600 MHz Cortex-A5 with NEON delivers up to 1.6 GFLOPS, sufficient for the 250 Hz ECG sample rate and the on-screen display composition without an external DSP. The industrial temperature grade (-40C to +85C) and long-life Microchip supply program (10+ years) match the regulatory lifecycle of medical devices.
Empfohlen
Point-of-Sale (POS) Terminals
The ATSAMA5D43A-CUR is well-suited for POS terminals combining a color touchscreen, barcode scanner, NFC reader, thermal printer, and Ethernet backhaul. The on-die maXTouch handles the cashier touchscreen, the LCD controller drives the customer-facing display, and the dual GMAC separates the secure payment LAN from the store LAN. Hardware video decode enables product-promotion video playback on the customer screen during idle time. Linux mainline support means Android 9/10 ports are feasible for retailers that prefer Android-based POS software stacks.
Empfohlen
Industrial Printer Control Boards
In label and panel printers, the ATSAMA5D43A-CUR drives the LCD status panel through its 24-bit LCD controller, runs the print engine through SPI/UART, and decodes incoming print jobs in H.264/MPEG-4 when the printer doubles as a video label preview terminal. The 16-bit DDR2/LPDDR controller keeps image buffers in external memory, and the dual USB 2.0 ports support both host (USB stick / scanner) and device (service PC) roles. Industrial temperature grade and Microchip's 10-year longevity program make it a strong fit for factory-floor printers.
Empfohlen
Smart Energy Gateways and Sub-Station RTUs
The ATSAMA5D43A-CUR acts as a sub-station Remote Terminal Unit (RTU) by aggregating IEC 61850, DNP3, and Modbus traffic over the dual Gigabit EMAC, while running local analytics (load forecasting, power-quality FFT) on the NEON engine. The 600 MHz Cortex-A5 with hardware video decode allows the same RTU to drive a 5-inch color touch HMI for field technicians - eliminating the need for a separate panel PC. The -40C to +85C industrial temperature range and Microchip's longevity program fit the 15-20 year service life of sub-station equipment.
Empfohlen
Ruggedized Handheld Data Terminals
The ATSAMA5D43A-CUR powers rugged handhelds used in warehouses, military logistics, and field-service fleets by combining the 5-inch WVGA maXTouch display, barcode scanner, GPS, and LTE/5G modem under a single Linux image. The hardware video decoder allows the device to play training videos or repair instructions directly on the unit without streaming. The 600 MHz Cortex-A5 plus NEON comfortably runs the inventory-management UI and AES-encrypted local database at the same time, while the 289-LFBGA's small 14x14 mm footprint leaves room for a 5000 mAh battery.

Wichtigste Unterscheidungsmerkmale
- On-die maXTouch capacitive touch controller with hardware video decoder in same 289-LFBGA package (vs. ATSAMA5D42A-CU)
- Full multimedia IP set within a single 600 MHz Cortex-A5 + NEON device (vs. ATSAMA5D41B-CUR)
- Direct 289-LFBGA footprint and software-compatible second source (vs. ATSAMA5D43B-CU)
Designhinweise
Estimated: The ATSAMA5D43A-CUR ships in a 289-LFBGA with 0.8 mm ball pitch on a 14x14 mm body. Production PCB layout should use at least a 4-layer stack-up with 1 oz copper on outer layers and 0.5 oz on inner layers. Microvia-in-pad is recommended for the inner-row balls to break out the DDR_A0..A15, DDR_D0..15, and LCD_DATA0..23 buses cleanly. Reference the ATSAMA5D4-XULT and AC320005-5 reference designs from Microchip for the exact ball escape pattern and decoupling network (10uF bulk + 100nF per power pin).
Estimated: At full 600 MHz with both CPU and video decoder active, the typical core power dissipation is in the 0.8 W to 1.2 W range depending on DDR2/LPDDR traffic. The 289-LFBGA package's bottom-exposed die pad must be soldered to a continuous ground plane with thermal vias (0.3 mm drill, 0.6 mm pitch, filled and capped) to keep the junction temperature within the -40C to +85C industrial range. Add 4-6 thermal vias under the e-pad for every 1 sq mm of e-pad area as a baseline.
Do not confuse the ATSAMA5D43A (with on-die maXTouch, video decode) with the ATSAMA5D42A (with 3D Texture Mapper instead of maXTouch) - both share the same 289-LFBGA footprint and same 600 MHz core, but the multimedia IP is different. For capacitive touch applications, use the ATSAMA5D43A-CUR only; for 3D-accelerated graphics without touch, use the ATSAMA5D42A-CU. Also note the 'CU' suffix = tape-and-reel; the 'CU' part without an 'R' is the same silicon but may be supplied in tray. Verify boot mode strap (BMS pin) before PCB fab - ROM-code boot order affects first-power-on behavior.
Keep the DDR2/LPDDR2 trace length matched within 25 mils for the data byte lanes and 50 mils for the address/command lanes to the ATSAMA5D43A-CUR. Route the two USB 2.0 differential pairs (90 ohm, length-matched within 150 mils) on the top layer with a continuous ground reference plane beneath, no splits. Place the 24 MHz main crystal within 5 mm of the XIN/XOUT pins and guard it with a ground ring. Reference the SAMA5D4 hardware design checklist (Microchip application note) for the full checklist.
Estimated: The ATSAMA5D43A-CUR requires a 3.3 V main supply for core and IO, plus a separate VDDIODDR rail (1.8 V typical for DDR2, 1.2 V for LPDDR2). Use a low-noise LDO such as the MCP1755 or a buck regulator with at least 80 dB PSRR at 1 kHz for VDDIODDR to avoid display artifacts. Add a 4.7uF X7R ceramic + 100nF X7R bypass on each VDDCORE pin. Power-up sequencing requires VDDCORE before VDDIODDR; the on-die power-on-reset block handles this when both rails rise within 50 ms of each other.
