Microchip Technology SAMA5D27 SOM1 System-On-Module

Microchip Technology SAMA5D27 SOM1 System-On-Module is based on the 32-bit Arm® Cortex®-A5 SAMA5D27 and 1Gb DDR2 SDRAM running up to 500MHz. The SAMA5D27 SOM1 can reduce time to market by simplifying hardware design and software development. The SOM also limits the design rules of the main application board, reducing overall PCB complexity and cost. The board features a wide range of peripherals, a user interface, and expansion options. The SAMA5D27 SOM1 comes with a free Linux distribution and bare metal C examples to easily get started with development.
