This application note describes how the secure boot and secure flash features operate with the Cypress® CYW4390X family of embedded wireless system-on-a-chip (SoC) devices. This family includes the CYW43903, CYW43907, and CYW43909 devices. Secure boot and secure flash features are not required during the early product development phase. As feature functionality involves programming one-time programmable (OTP) nonvolatile memory, it is important to exercise diligent precautions before starting the process. This document is intended for design and applications engineers.
