CYW4343X
Introduction
This document provides details of the functional, operational, and electrical characteristics of the Cypress CYW4343X. It is intended
for hardware design, application, and OEM engineers.
Cypress part numbering scheme
Cypress is converting the acquired IoT part numbers from Broadcom to the Cypress part numbering scheme. Due to this conversion,
there is no change in form, fit, or function as a result of offering the device with Cypress part number marking. The table provides
Cypress ordering part number that matches an existing IoT part number.
