Microchip has recently launched the System on Module (PN: ATSAMA5D27-SOM1ATSAMA5D27-SOM1) which targets embedded Linux applications. Featuring an ARM-based MPU Microchip have done all the very complex design work leaving users to simply place the module onto their application board.
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.
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.
The module includes several components from Microchip.
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.
For fast development, Microchip offers the ATSAMA5D27-SOM1-EK1 ATSAMA5D27-SOM1-EK1 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.
