1. Overview
1.1 Overview
The Cypress CYW43570 single-chip device provides the highest level of integration for a mobile or handheld wireless system, with
integrated IEEE 802.11 a/b/g/n/ac MAC/baseband/radio and Bluetooth 4.1 + EDR. It provides a small form-factor solution with
minimal external components to drive down cost for mass volumes and allows for handheld device flexibility in size, form, and function.
Comprehensive power management circuitry and software ensure the system can meet the needs of highly mobile devices that require
minimal power consumption and reliable operation.
Figure 2 shows the interconnect of all the major physical blocks in the CYW43570 and their associated external interfaces, which are
described in greater detail in the following sections.
