The new SAMA5D27 Wireless System-On-Module 1 (ATSAMA5D27-WLSOM1) is a small single-sided SOM based on our high-performance System-in-Package (SiP) 32-bit Arm® Cortex®-A5 processor-based MPU SAMA5D27 with 2 Gb LPDDR2 SDRAM running up to 500 MHz. The ATSAMA5D27-WLSOM1 is built on a common set of proven Microchip components to reduce your time to market by simplifying hardware design and software development. It is delivered with a free Linux® distribution and bare metal C examples.

As well as the SiP, the SOM integrates the following:
