SmartConnect WINC3400
Wireless Network Controller
The Atmel® SmartConnect ATWINC3400 is a single-chip IEEE 802.11 b/g/n RF/Baseband/MAC network controller and Bluetooth®
4.0 Low Energy (BLE) compliant module optimized for low-power mobile applications. It supports single stream 1x1 802.11n mode,
providing up to 72 Mbps throughput. The ATWINC3400 device features a fully integrated power amplifier, LNA, switch and power
management, as well as an on-chip microcontroller (MCU) and integrated Flash memory for system software. Implemented in 65nm
CMOS technology, it offers very low power consumption while simultaneously providing high performance and a minimal bill of materials.
The ATWINC3400 wireless network controller utilizes highly optimized coexistence protocols. It provides multiple peripheral interfaces,
including UART, SPI, I2C, and SDIO. For simplicity, both Wi-Fi and BLE can run on a single peripheral interface (SPI).
The only external clock sources required is a high-speed crystal or oscillator with a wide range of reference clock frequencies supported
(14-40 MHz) and a 32.768 kHz clock for sleep operation. The device is available in QFN packaging.

Power Architecture and Consumption
The ATWINC3400 has multiple device states, depending on the state of the 802.11 and Bluetooth subsystems. It is possible for both
subsystems to be active at the same time. To simplify the device power consumption breakdown, the following basic states—for which
only one subsystem can be active at a time—are defined as follows:
•
•
•
•
•
•
WiFi_ON_Transmit: Device is actively transmitting an 802.11 signal
WiFi_ON_Receive: Device is actively receiving an 802.11 signal
BT_ON_Transmit: Device is actively transmitting a Bluetooth signal
BT_ON_Receive: Device is actively receiving a Bluetooth signal
Doze: Device is neither transmitting nor receiving (device state is retained)
Power_Down: Device is powered down with CHIP_EN low and supplies connected
Accelerating RF Design
To help designers accelerate development, the ATWINC3400A-MU is offered as a single chip, module, or evaluation kit for fast integration.
