Design win; Cypress’ wireless silicon on Raspberry Pi Zero W IoT board
Cypress’ CYW43438 combo solution provides 802.11n Wi-Fi for Internet coonectivity, along with 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.
Eben Upton, CEO of Raspberry Pi Trading comments, “The highly integrated Cypress 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.”
Cypress adds, “The Raspberry Pi 3 has shipped more than four million units to date, and we expect the new Raspberry Pi Zero W and future boards will encourage users from their diverse customer base in education, industrial and mass-market IoT to look at other Cypress solutions as well.”
The Raspberry Pi Zero W features a 1 GHz, single-core CPU, 512 MB 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 combo solution integrates IEEE 802.11n Wi-Fi and Bluetooth in a single-chip solution to enable small-form-factor IoT designs. The solution provides up to 150 Mbps PHY data rates and coexistence management for advanced Wi-Fi and Bluetooth streaming applications. The combo solution is supported on Cypress’ Wireless Internet Connectivity for Embedded Devices (WICED) Software Development Kit (SDK), which provides code examples, tools and development support.
