ATSAMA5D27-WLSOM1

Overview

The ATSAMA5D27-WLSOM1 is a single-sided System-on-Module based on the Microchip SAMA5D27 MPU and an integrated ATWILC3000 Wi-Fi/BT module. It features a 32-bit ARM Cortex-A5 processor running at 500 MHz, paired with 2 Gbit LPDDR2 SDRAM within a System-in-Package (ATSAMA5D27C-LD2G-CU). The module integrates a 64 Mb Serial Quad I/O Flash memory, a KSZ8081 Ethernet PHY, and an ATECC608A Secure Element. Designed for industrial applications, it operates between -40°C and 85°C with a main supply voltage of 3.0V to 5.5V.

Feature Summary

• Integrated wireless connectivity via IEEE 802.11 b/g/n Wi-Fi and Bluetooth module (ATWILC3000-MR110UA)
• System-in-Package (SiP) combining SAMA5D27 MPU and 2 Gbit LPDDR2 SDRAM
• Hardware security provided by ATECC608A CryptoAuthentication secure element
• On-board power management unit (MCP16502) supporting multiple independent voltage domains

Applications

• Industrial Control and Automation
• Smart Appliances
• Human Machine Interfaces (HMI)
• IoT Gateway
• Access Control Panels

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or direct channels. Confirm that the specific revision matches the required hardware design specifications. Ensure compliance with RoHS directives and relevant environmental standards before integration into final products.

Selection Notes

Select this module when both wired Ethernet and wireless connectivity are required in a compact form factor. It is suitable for designs needing robust hardware security features like secure boot and key storage. Consider the 40.8 x 40.8 mm footprint and 0.8mm pitch for PCB layout constraints.

Part Context

This module belongs to the SAMA5D2 Wireless SOM1 series, designed to simplify Linux-based embedded development. It builds upon the standard SAMA5D27 SOM1 architecture by adding integrated wireless capabilities, reducing the need for separate radio subsystems on the host application board.

Replacement Considerations

For non-wireless requirements, consider the ATSAMA5D27-SOM1. For higher memory configurations, evaluate the ATSAMA5D27C-D1G-CU SiP variants. Verify pin compatibility if migrating from older SOM generations.
