The CYW43438 chipset provides 802.11n Wi-Fi with algorithms to support simultaneous Bluetooth 4.1 operations such as audio streaming and low-power Bluetooth Low Energy (BLE) connections to smartphones, sensors and other low-power devices.
The chip provides up to 150Mbit/s PHY data rates and coexistence management for advanced Wi-Fi and Bluetooth streaming applications.
Eben Upton, CEO of Raspberry Pi Trading, writes:
“With Cypress’ combo solution on board, Raspberry Pi Zero W allows designers to connect to the most pervasive Wi-Fi networks for infrastructure connections and offers Bluetooth to connect to smartphones and other low-power smart devices.”
“The highly integrated solution enabled us to offer our boards at the right price points for wide scale adoption by IoT developers, eliminating the need for them to purchase wireless dongles that can cost more than the boards themselves.”
The Raspberry Pi Zero W features a 1GHz, single-core CPU, 512MB RAM, Mini-HDMI and Micro-USB ports, composite video and reset headers and a CSI camera connector, along with 802.11n wireless LAN and Bluetooth 4.1 wireless connectivity.
Wi-Fi and Bluetooth chips from Cypress were also used on the Raspberry Pi 3.
