Simplifying Embedded LINUX MPU Designs

Introducing the Microchip SAMA5D27 SOM1 System-on-Module

The SAMA5D27 SOM1 (168-2814) is a small single-sided System-On-Module (SOM) featuring an ARM-based MPU Microchip and 1Gb DDR2 SDRAM running up to 500 MHz. The module is a small-single sided PCB, 40mm x 38mm, industrial temperature grade (-40/+85C) and requires a single 3.3V power supply for operation. 

Designers can consider the SoM (System on Module) to be just one of the components they require to build their product, longevity of supply is assured via Microchip’s history of long-term supply.

 Linux Ready

A ready-to-go Linux solution is supplied with Microchip’s commitment to in-house Linux support. Microchip contributes to the Linux Mainline and offers a Yocto-based build manager, allowing developers to build their own Linux distribution. Microchip have done all the very complex design work leaving users to simply place the module onto their application board.

Microchip components onboard

The SAMA5D27 SOM1 includes industry standard ARM MPU with DDR Memory, 10/100Mbit Ethernet PHY, (MAC address is programmed into a small serial EEPROM), a power-management controller, and non-volatile boot memory.

For the more adventurous, the SOM can be used as a reference design: Microchip provides a reference implementation with full access to design files for those who want to consider making modifications or migrate to discrete designs.

ATSAMA5D27-SOM1-EK1 - fast LINUX development

For fast development, Microchip offers the ATSAMA5D27-SOM1-EK1 (165-5130) which incorporates the SoM. This board is backed by a Board Support Package (BSP) with Linux kernel and drivers for the SoM’s MPU peripherals and integrated circuits.
