ATWINC3400 Wi-Fi/BLE Network Controller - Software

Design Guide

User Guide

Introduction

Atmel® SmartConnect ATWINC3400 SoC is an IEEE® 802.11 b/g/n and

Bluetooth® Smart BLE network controller for applications in the Internet-of-

Things. It is an ideal add-on to existing MCU solutions bringing Wi-Fi® and

network capabilities through an SPI- -to Wi-Fi interface. The WINC3400 AT

connects to any Atmel AVR® or Atmel | SMART MCU with minimal resource ™

requirement s.

Features

 Wi-Fi IEEE® 802.11 b/g/n STA AP modes and

 Wi-Fi Protected Setup (WPS)

 Discovery and provisioning via Smartphone using BLE

 Support of WEP WPA/WPA2 personal security and

 Embedded network stack protocols to ooad work from the host MCU. This

allows operation with a wide range of MCUs including low end MCUs.

 Embedded 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 optional provisioning using AP mode

 Ultra-low cost IEEE 802.11 b/g/n RF/PH/MAC SoC

 Ultra-low power Bluetooth SMART (BLE 4.0 SoC with Integrated MCU, )

Transceiver, Modem, MAC, PA, TR Switch, and Power Management Unit

 Fast boot from on-chip Boot ROM

 8Mb internal Flash memory

 Low power consumption with dierent power saving modes

 SPI, I2C, and UART support

 Low footprint host driver with the following capabilities:

– Can run on 8, 16, and 32 bit MCU

– Little and Big endian support

– Consumes about 8KB of code memory and 1KB of data memory on host
