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.
