ATWINC3400 Wi-Fi® Network Controller Software Design Guide

PublishTime：2021-10-26

Microchip’s SmartConnect ATWINC3400 is an IEEE® 802.11 b/g/n network controller SoC and Bluetooth ® Smart BLE network controller for Internet of Things (IoT) applications. It is an ideal add-on to the existing microcontroller (MCU) solutions bringing BLE, Wi-Fi and network capabilities through an SPI-to-Wi-Fi/BLE interface. The ATWINC3400 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
■ Discovery and Provisioning via Smartphone using BLE
■ 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 Internal Flash Memory
■ 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
