Introduction

Microchip’s SmartConnect ATWINC15x0 is an IEEE

®

802.11 b/g/n network controller SoC for Internet of Things

(IoT) applications. It is an ideal add-on to the existing microcontroller (MCU) solutions bringing Wi-Fi and network

capabilities through an SPI-to-Wi-Fi interface. The ATWINC15x0 connects to any Microchip AVR

®

or Microchip

SMART

™

MCU with minimal resource requirements.

Features

•Wi-Fi IEEE 802.11 b/g/n STA, and AP modes

•Wi-Fi Protected Setup (WPS)

•Support of WEP, WPA/WPA2 Personal, and WPA/WPA2 Enterprise Security

–EAP-TLS

–EAP-PEAPv0/1 with TLS

–EAP-TTLSv0 with MSCHAPv2

–EAP-PEAPv0/1 with MSCHAPv2

•Embedded network stack protocols to offload work from the MCU (minimize the host CPU requirements). This

allows the Wi-Fi Network Controller (WINC) to operate with a wide range of MCUs including low-end MCUs.

•Embedded uIP TCP/IP stack with BSD-Style socket API

•Embedded network protocols

–DHCP client/server

–DNS resolver client

–SNTP client for UTC time synchronization

•Embedded TLS security abstracted behind BSD-style socket API

•HTTP server for provisioning over AP mode

•Ultra-low C IEEE 802.11 b/g/n RF/PH/MAC SoC

•Fast boot from On-Chip boot ROM

•8 Mb (WINC1510) and 4 Mb (WINC1500) internal Flash memory with Over-the-Air (OTA) firmware upgrade

•WINC1510 support Host File Download feature which can be used for host MCU over the air firmware update

•Low-power consumption with different Power Save modes

•Low footprint host driver with the following capabilities:

–Can run on 8-, 16-, and 32-bit MCU using SPI interface

–Little- and big-endian support
