ATWINC15x0/ATWINC3400

Integrated Serial Flash and Memory Download Procedure

Introduction

The ATWINC15x0/ATWINC3400 features an on-chip microcontroller and integrated SPI Flash memory for

the system firmware. The serial Flash memory also stores the root certificate required for the TLS/SSL

connection and the power gain values used by the transceiver. This application note details the download

procedure of firmware, TLS/SSL root certificates, and TX power gain values into WINC serial Flash

through different supported serial interfaces like SPI/UART. This document also covers some useful

troubleshooting tips for download failures.

Note: This Flash memory download procedure is applicable for both the ATWINC15x0 and

ATWINC3400 boards. The ATWINC15x0 is used for demonstrating the download procedure.
