The CYW43438 integrates IEEE 802.11n Wi-Fi and Bluetooth in a single chip to enable small-form-factor IoT designs, according to Cypress.
Raspberry Pi has selected a chipset from Cypress Semiconductor to provide Bluetooth and Wi-Fi interfaces on its new Raspberry Pi Zero W board for IoT applications.
The Cypress CYW43438 combo chip provides 802.11n Wi-Fi for developers to connect their applications to the Internet, along with advanced coexistence algorithms enabling 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. Raspberry Pi's original board with Wi-Fi and Bluetooth connectivity, the Raspberry Pi 3, also uses a Cypress wireless solution.
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.
Cypress' CYW43438 integrates IEEE 802.11n Wi-Fi and Bluetooth in a single chip to enable small-form-factor IoT designs. The solution provides up to 150Mbps PHY data rates and coexistence management for advanced Wi-Fi and Bluetooth streaming applications.
The chip is supported on Cypress' Wireless Internet Connectivity for Embedded Devices (WICED) Software Development Kit (SDK), which provides code examples, tools and development support, according to Cypress.
