ATSAMA5D26B-CUR 概要
An ARM Cortex-A5 MPU (Microprocessor Unit) is an applications-class CPU core implementing the ARMv7-A architecture with optional NEON SIMD and VFPv4 floating-point support. The Cortex-A5 sits within the broader hierarchy: Cortex-A5 -> 32-bit applications core -> ARM Cortex family -> MPU -> system-on-chip. SAMA5D2 MPUs from Microchip integrate the Cortex-A5 with DDR/LPDDR controllers, image sensor interfaces, LCD controllers, Ethernet MAC, USB, and hardware crypto accelerators, replacing discrete host processors in embedded designs.
Key features of the ATSAMA5D26B-CUR include: 500 MHz maximum CPU clock, hardware cryptography (AES, SHA, TRNG), dual CAN-FD controllers, a 1 Gbps Ethernet MAC with 1588 PTP support, a 12-bit ISP image sensor pipeline, an LCD controller up to WXGA (1280x720), 5 uA backup-mode current for battery applications, and a low-power 0.8 mm ball-pitch package. The device operates from a single 1.2 V core supply with 1.8 V/3.3 V I/O rails.
The SAMA5D2 architecture pairs the Cortex-A5 core with tightly-coupled SRAM, a multi-layer AHB/APB bus matrix, dedicated peripheral DMA, and on-chip OTP for secure key storage. This heterogeneous fabric enables deterministic interrupt latency suitable for industrial HMI and motor-control co-processing while sustaining Linux/Android class application workloads.
Typical applications include industrial HMI panels, smart energy gateways, building automation controllers, medical patient monitors, point-of-sale terminals, and ruggedized IoT edge nodes. The wide operating temperature and integrated security engine also make it suitable for automotive aftermarket telematics and fleet-management gateways.
When designing with this MPU, ensure the 0.8 mm BGA is mounted on at least a 4-layer PCB with microvia-in-pad capability for the inner-row balls. Provide a low-noise LDO for the 1.2 V core rail and follow Microchip's power-sequencing recommendations in the datasheet to avoid latch-up during warm reset.

設計ノート
The 289-LFBGA 14x14 mm package uses 0.8 mm ball pitch. Microchip recommends at least a 4-layer PCB stack-up with microvia-in-pad for the inner-row balls, and a 1.6 mm finished board thickness to ensure reliable BGA soldering. Escape routing on the top layer should use 4-mil traces with 4-mil spacing to fan out from the inner balls; consult the SAMA5D2 hardware design guide for via pattern templates. Use ENIG surface finish for industrial-grade reliability.
Power sequencing is critical: VDDCORE (1.2 V) must rise before VDDIO (3.3 V / 1.8 V), with a maximum delay of 50 ms specified in the datasheet. Use a dedicated PMIC such as the Microchip MCP16502 or a discrete LDO+sequencer pair. The backup mode draws 5 uA from the backup battery rail; ensure a low-leakage Schottky diode isolates this rail from the main supply during power-down to maximize RTC retention.
Estimated thermal analysis: with VDDCORE 1.2 V at 500 MHz full-load, the MPU dissipates approximately 0.6-0.9 W depending on peripheral utilization. With the LFBGA package theta_JA of approximately 25 C/W on a 4-layer JEDEC test board, junction temperature rise is roughly 15-23 C above ambient. For -40C to +85C industrial operation, derating to 70 C ambient is recommended; for sealed enclosures, route thermal vias under the exposed die pad to an internal copper plane.
Common pitfalls when designing with the ATSAMA5D26B-CUR: (1) DDR3L vs LPDDR2 power-rail differences - the SAMA5D26 supports both but boot ROM configuration differs; (2) JTAG/SWD pin sharing with SDMMC - isolate with series resistors if both interfaces are used during development; (3) BOOT pins must be pulled to known states via 10k resistors to select the correct boot source (NAND, SD, SPI flash, or USB); (4) the NRST input is sensitive to noise - decouple with 100 nF directly at the pin.
