SOMs Simplify Industrial-Grade Linux Designs

To remove the traditional design complexity associated with industrial-grade Linux-based designs, Microchip Technology offers a system on module (SOM) featuring the SAMA5D2 MPU. The ATSAMA5D27-SOM1 contains the ATSAMA5D27C-D1G-CU System in Package (SiP), and integrates power management, non-volatile boot memory, Ethernet PHY and high-speed DDR2 memory onto a small, single-sided Printed Circuit Board (PCB).


The Arm Cortex-A5-based SAMA5D2 SiP, mounted on the SOM PCB or available separately, integrates 1 Gb DDR2 memory. Impedance matching is done in the package, not manually during development, so the system will function properly at normal and low-speed operation. Three DDR2 memory sizes (128 Mb, 512 Mb and 1 Gb) are available for the SAMA5D2 SIP and optimized for bare metal, Real-time Operating System (RTOS) and Linux implementations.


Sensors 2018 Hits Silicon Valley June 26-28!

Join thousands of engineers this June in San Jose at the sensor industry’s biggest event! With 65+ Technical Sessions, 100+ Leading Speakers, and 300+ Interactive Exhibits, there’s more opportunity than ever to connect with this booming industry and the technologies driving it. See thousands of the newest technologies in action, learn about the latest applications, including AI, Autonomous Vehicles, IoT, and Medical, and develop invaluable partnerships at the only event dedicated to sensors, connectivity, and systems.


The SAMA5D2 family features high levels of security including PCI compliance. With integrated Arm TrustZone and capabilities for tamper detection, secure data and program storage, hardware encryption engine, secure boot and more, customers can work with Microchip’s security experts to evaluate their security needs and implement the level of protection that’s right for their design. The SAMA5D2 SOM also contains Microchip’s QSPI NOR Flash memory, a Power Management Integrated Circuit (PMIC), an Ethernet PHY and serial EEPROM memory with a Media Access Control (MAC) address to expand design options.


The SOM1-EK1 development board provides a convenient evaluation platform for both the SOM and the SiP. A free Board Support Package (BSP) includes the Linux kernel and drivers for the MPU peripherals and integrated circuits on the SOM. Schematics and Gerber files for the SOM are also available.


Pricing and Availability


The ATSAMA5D2 SiP is available in four variants starting with the ATSAMA5D225C-D1M-CU in a 196-lead BGA package for $8.62 each in 10,000 unit quantities. The ATSAMA5D27-SOM1 is available now for $39 each/100 and the ATSAMA5D27-SOM1-EK1 development board is available for $245 each. More information and specs abound!
