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
ď‚· Wi-Fi Protected Setup (WPS)
ď‚· Discovery and provisioning via Smartphone using BLE
ď‚· 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.
ď‚· Embedded TCP/IP stack with BSD-style socket API
ď‚· Embedded network protocols
– DHCP client/server
– DNS resolver client
– SNTP client for UTC time synchronization
ď‚· Embedded TLS security abstracted behind BSD-style socket API
ď‚· HTTP Server for optional provisioning using AP mode
ď‚· Ultra-low cost IEEE 802.11 b/g/n RF/PH/MAC SoC
ď‚· Ultra-low power Bluetooth SMART (BLE 4.0 SoC with Integrated MCU, )
Transceiver, Modem, MAC, PA, TR Switch, and Power Management Unit
ď‚· Fast boot from on-chip Boot ROM
ď‚· 8Mb internal Flash memory
 Low power consumption with dierent power saving modes
ď‚· SPI, I2C, and UART support
ď‚· 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
MCU
