SAMA5D27 Wireless SOM1

ATSAMA5D27-WLSOM1

Introduction

The Microchip SAMA5D27 Wireless System-On-Module 1 (ATSAMA5D27-WLSOM1) is a small single-sided

SOM based on the high-performance System-in-Package (SiP) 32-bit Arm® Cortex®-A5 processor-based MPU

SAMA5D27, 2 Gb LPDDR2-SDRAM running up to 500 MHz, and Wi-Fi® plus Bluetooth® (Wi-Fi/BT) Wireless

module.

The ATSAMA5D27-WLSOM1 is built on a common set of proven Microchip components to reduce time to market by

simplifying hardware design and software development.

The ATSAMA5D27-WLSOM1 also limits design rules of the main application board, reducing overall PCB complexity

and cost. The ATSAMA5D27-WLSOM1 is delivered with a free Linux® distribution and bare metal C examples.
