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.

2. Limited feature compared to SAMA5D2 due to the WLSOM1 internal use of specific functionality, for example,
QSPI, GMAC.
3. Limited feature compared to SAMA5D2 due to the use of a part of the functionality for other features in the
WLSOM1, for example, GMAC, ISC, FLEXCOM, etc.
