Description

General part information

ATWINC3400-IC Series

Microchip's ATWINC3400 is an IEEE 802.11 b/g/n plus Bluetooth 5 Core Specification, Internet of Things (IoT) network controller module. It is the ideal add-on to existing microcontroller (MCU) solutions, offering Wi-Fi® and Bluetooth® Low Energy (BLE) network capabilities through a SPI-to-Wi-Fi interface. The ATWINC3400 connects to any Microchip PIC® or SAM MCU with minimal resource requirements. A MCU host driver can be found in the [Advanced Software Framework](https://www.microchip.com/en-us/tools-resources/develop/libraries/advanced-software-framework) (ASF) and in MPLAB(r) [Harmony v3](https://www.microchip.com/en-us/tools-resources/configure/mplab-harmony).

The ATWINC3400’s most advanced mode is a single-stream 1 x 1 802.11n mode. The ATWINC3400 features a fully integrated power amplifier, LNA, switch and power management. The ATWINC3400 also features an on-chip processor and integrated Flash memory for system software with built-in coexistence mechanism for concurrent Wi-Fi and BLE functionality. The only external clock source needed for the ATWINC3400 is a high-speed crystal or oscillator. The ATWINC3400 is available in a 36-pin module with dimensions of 22.4 x 14.7 mm.

Microchip's complimentary and confidential [Wireless Check online design review service](https://www.microchip.com/en-us/support/design-help/design-check-services) is available for customers who have selected our products for their application design-in\*.
