ATSAMW25-MR210PB

IEEE 802.11 b/g/n SmartConnect Wi-Fi Module

DATASHEET

Description

The Atmel® | SMART SAMW25 module is based on the industry-leading low­power 2.4GHz IEEE® 802.11 b/g/n Wi-Fi® ATWINC1500 SoC (System on Chip)
combined with the ARM® Cortex®-M0+ based microcontroller technology from
Atmel.

This turnkey system provides an integrated software solution with application and
security protocols such as TLS and integrated network services (TCP/IP stack)
which are all available through Atmel Studio 6 integrated development
environment (IDE). The Atmel SmartConnect modules offer the ideal solutions for
designers seeking to add Wi-Fi connectivity with minimal previous experience in

802.11, IP Stack, or RF. Atmel SmartConnect Wi-Fi opens the door of the
Internet of Things (IoT) to the vast array of battery-powered devices and
applications requiring the integration of WLAN connectivity without compromising
on cost or power consumption. While we compete with other Wi-Fi modules on
size, RF performance, cost, and other characteristics, the Atmel SmartConnect
product family has a distinctive advantage when it comes to power consumption
and power saving modes. The ATSAMW25 device is a standalone end point,
where a complete small application can be executed on the module by itself.
