ATSAMA5D27-SOM1-EK1 Descripción general
An evaluation kit (EK) is a printed-circuit-board hardware development platform that integrates the target SoC/SiP with power, memory, debug, and standard I/O headers so engineers can validate firmware and applications before designing a custom carrier. The ATSAMA5D27-SOM1-EK1 sits at the top of the SAMA5D2 evaluation hierarchy above discrete SAMA5D2 Xplained boards, providing the lowest-effort path to running embedded Linux on a Cortex-A5 with hardware-floating-point and rich connectivity.
Key features of the baseboard include an on-board debugger, multiple mikroBUS sockets, an LCD/touch connector, USB device and host ports, Ethernet (GMII/RGMII expansion), CAN, two SD card slots, JTAG/SWD, audio codec interface, and expansion headers that map nearly every SAMA5D2 signal to a 0.1-inch header. The integrated Power Management IC and secure-element footprints on the ATSAMA5D27-SOM1 module simplify power-tree design and security key storage for IoT edge nodes.
The SAMA5D27 SiP architecture pairs the Cortex-A5 core with a peripheral set including 12-bit ADC, hardware crypto accelerators (AES, SHA, TRNG), and a 24-bit peripheral-touch controller, allowing the same evaluation kit to be reused across HMI, connectivity gateway, and secure-credential prototypes. The DDR2 interface is fully validated at 500 MHz, removing the timing and signal-integrity work normally needed for production designs.
Typical applications include industrial HMI panels, smart-home gateways, edge IoT sensors with secure boot, Linux-based point-of-sale terminals, and connected-utility metering. Designers also reuse the kit as a low-volume ODM reference for products based on the ATSAMA5D27 SiP. A single design consideration dominates: when migrating to production, swap the kit's baseboard for a custom carrier that hosts the ATSAMA5D27-SOM1 module directly - the pinout is documented in the SOM1 datasheet.

Aplicaciones típicas
ATSAMA5D27-SOM1-EK1 es adecuado para 6 aplicacións: Embedded Linux Prototyping, Industrial HMI Development, Smart Home Gateway Reference, Secure Edge IoT Node, Connected Utility Metering, Low-Volume ODM Reference Design.
Embedded Linux Prototyping
The ATSAMA5D27-SOM1-EK1 is the canonical Microchip platform for embedded Linux bring-up on the SAMA5D27 SiP. The on-board debugger, pre-validated 1-Gbit DDR2 interface, and 64-Mbit NOR Flash allow engineers to boot mainline Linux, Buildroot, or Yocto images in minutes without designing custom power, reset, or boot-memory circuits. The 500 MHz Cortex-A5 with hardware floating-point is fast enough to validate userspace applications, device drivers, and kernel subsystems before porting to a custom carrier. Compared with bare Xplained boards, the EK1 removes the DDR2 layout risk that dominates first-pass bring-up on Cortex-A designs.
Recomendado
Industrial HMI Development
The ATSAMA5D27-SOM1-EK1 baseboard exposes an LCD/touch connector, audio codec interface, and multiple mikroBUS sockets that map directly to typical industrial-HMI architectures. The Cortex-A5 core runs LVGL, Qt, or WebKit-based GUI stacks comfortably, while the 1-Gbit DDR2 provides enough headroom for 800x480 and small 1080p framebuffers. The on-board peripherals let engineers prototype resistive and capacitive touch panels plus rotary encoders without spinning a custom PCB. Drop the production carrier around the ATSAMA5D27-SOM1 module and the same firmware ports unchanged.
Recomendado
Smart Home Gateway Reference
With the ATSAMA5D27-SOM1-EK1's GMII/RGMII Ethernet expansion, dual CAN, USB host/device, and SD card slots, the kit doubles as a smart-home gateway reference. The SAMA5D27 SiP's hardware crypto accelerators (AES, SHA, TRNG) plus the module's secure-element footprint support secure boot and TLS at the edge. Linux-friendly networking stacks (iptables/nftables, OpenWRT) run on the Cortex-A5 at 500 MHz with margin for routing, MQTT brokering, and local automation. The EK1 is widely used to de-risk production gateways before the custom carrier is built.
Recomendado
Secure Edge IoT Node
The ATSAMA5D27-SOM1-EK1 validates secure-boot flows and hardware-trusted execution on the SAMA5D27. The module's secure-element footprint and PMIC simplify power-tree and key-storage design for tamper-resistant IoT nodes. Engineers use the kit to prototype OTA update flows with signed images, hardware-bound keys, and TRNG-seeded session keys. Compared with discrete SAMA5D2 boards, the EK1 also exposes the on-board debugger for fast secure-state inspection.
Recomendado
Connected Utility Metering
For utility metering prototypes, the ATSAMA5D27-SOM1-EK1 provides dual CAN (for in-vehicle or field-bus networks), Ethernet expansion, and a low-power profile that fits battery-assisted metering designs. The 24-bit peripheral-touch controller and 12-bit ADC on the SAMA5D27 SiP connect to metering front-ends without external DSP, and the secure boot path is suitable for metrology certification. The kit lets engineers validate the entire metering stack - acquisition, signed telemetry, and secure provisioning - on production-equivalent silicon.
Recomendado
Low-Volume ODM Reference Design
Design houses use the ATSAMA5D27-SOM1-EK1 as the reference for low-volume ODM products built around the ATSAMA5D27-SOM1 module. The baseboard's expansion headers expose nearly every SAMA5D2 signal, which accelerates carrier-board schematic and layout reuse. After firmware is validated on the EK1, the production team spins a custom carrier that hosts the same SOM module, eliminating the DDR2 layout risk that normally dominates Cortex-A carrier design. This kit-to-SOM-to-product flow is the documented Microchip migration path for SAMA5D2 designs.

Notas de diseño
Power the EK1 baseboard from a regulated 5 V DC barrel jack (center-positive, 2.1 mm). The on-board PMIC inside the ATSAMA5D27-SOM1 module then generates all SAMA5D27 SiP and DDR2 rails. Estimated: at 500 MHz core with Ethernet and LCD active, total board power is approximately 4-5 W, so a 5 V/2 A supply provides comfortable margin. Do not back-feed 3.3 V from external sources; the PMIC's sequencing is required for clean DDR2 bring-up and safe boot.
When porting the EK1 design to a custom carrier, place the ATSAMA5D27-SOM1 module socket (or solder footprint) over a continuous ground plane and route the 1-Gbit DDR2 signals with 50 ohm controlled impedance and length matching per the SAMA5D27 datasheet. Estimated: keep DDR2 traces under 50 mm to maintain signal integrity. Add a 4-layer stack-up with dedicated ground and power planes; the EK1 reference layout is the recommended starting point.
Do not boot the SAMA5D27 SiP from 1.8 V microSD cards without re-validating the boot mode straps; the EK1 default uses an SD card boot image with specific pull-ups. Also, when migrating firmware from the EK1 to a bare ATSAMA5D27C-D1G-CU design, ensure the external PMIC is sequenced exactly like the SOM1 module's on-board PMIC - DDR2 training fails if the supply ramp timing is off by more than a few milliseconds.
The GMII/RGMII Ethernet expansion header on the EK1 is not impedance-controlled by default; use short flying leads (under 25 mm) to the PHY or, for production, replicate the EK1's reference stack-up. Estimated: RGMII edges have ~2 ns setup/hold budget, so any extra stub from the expansion header can cause CRC errors. Keep the optional 125 MHz clock trace short and matched within 25 mil.
