Wi-Fi & Bluetooth Combo Chip Powers New Raspberry Pi IoT board


Cypress announced that its Wi-Fi and Bluetooth combo chip has been used to offer robust wireless connectivity to the new Raspberry Pi 3 Model B+ IoT board.

The board with the CYW43455 combo SoC allows developers to quickly prototype industrial IoT systems and smart home products that leverage the benefits of 802.11ac such as faster downloads, better range, and lower power consumption by quickly exploiting deep sleep modes.

The CYW43455 can operate 802.11ac Wi-Fi at 2.4 and 5GHz, as well as simultaneous Bluetooth and Bluetooth Low Energy (BLE).


Previously, Raspberry Pi used the CYW43438 802.11n 2.4GHz Wi-Fi and Bluetooth combo chip.

“802.11ac­ Wi-Fi allows faster Internet connections, advanced coexistence algorithms for simultaneous Bluetooth and Bluetooth Low Energy (BLE) operations such as audio and video streaming, and low-power BLE connections to smartphones, sensors, and Bluetooth Mesh networks”, Cypress noted.

“Achieving reliable wireless connectivity in crowded airwaves is a foremost concern for developers of industrial IoT and smart home systems, which lead us to select Cypress’ 802.11ac combo SoC for the Raspberry Pi 3 Model B+ board,” said Eben Upton, CEO of Raspberry Pi Trading. “Our new board democratizes high-performance, interoperable and highly reliable 802.11ac Wi-Fi for use across a huge range of IoT products.”

The Raspberry Pi 3 Model B+ board features a 64-bit, quad-core processor running at 1.4GHz, 1GB RAM, full size HDMI and 4 standard USB ports, Gigabit Ethernet over USB2, Power over Ethernet capability, CSI camera connector and a DSI display connector. The platform’s resources, together with its 802.11ac wireless LAN and Bluetooth/BLE wireless connectivity, provide a compact solution for the intelligent edge of connected devices.

Cost Effective Power Modules For Space Critical Applications

The SoC is also supported in Cypress’ all-inclusive, turnkey Wireless Internet Connectivity for Embedded Devices (WICED) software development kit (SDK).
