A collaboration has been announced between Murata and Cypress Semiconductor, to develop the Type 1LV (CYW43012) solution, a low power, small form factor WiFi and Bluetooth module. This product improves battery life in wearables, smart home products, and portable audio applications.

When comparing Type 1LV (CYW43012) to the Type 1DX (CYW4343W), power usage in the previous is approximately 54% lower in DTIM 1, 60% in DTIM 3, up to 50% for 2.4GHz RX, and 28% for 2.4GHz TX.

Based on the Cypress CYW43012 combo chipset, the ultra-small dual-band WiFi 11a/b/g/n/ (11ac Friendly) +Bluetooth 5.0 module provides data transference rates up to 78Mbps on WiFi and 3Mbps on Bluetooth. The Type 1LV supports a broad range of popular processors including PSoC6, i.MX RT, STM32, i.MX, and IP Camera platforms, as well as Linux and RTOS based applications.

The Type 1LV uses highly sophisticated and enhanced hardware mechanisms and algorithms to ensure that WiFi and Bluetooth coexistence is optimised for maximum performance. An embedded Ipv6 network stack can be used to keep the host processor in sleep mode while maintaining network connections. The module also supports BLE 2Mbps, LE Secure Connections, LE Privacy 1.2, and LE Data Packet Length Extension.

The device operates seamlessly in dual-band networks with increased energy efficiency and enhanced security providing optimal performance in WiFi 5 networks. The module size is 10x7.2x1.4mm. It will have a reference antennae design for FCC/IC certifications and CE conducted test to provide a lower development cost and faster time to market.

“Teaming up with Cypress allows us to leverage our combined expertise in delivering breakthrough solutions that are game changers for the market,” said Koichi Sorada, Product Manager, Connectivity Solutions for Murata Europe. “Using our proprietary packaging and miniaturisation technologies, Murata leads in developing turnkey, transformational tools that ease integration and enable connectivity to help bring IoT to fruition. With this lowest WiFi power module, we now enable a new class of products that were previously designated for Bluetooth.”

Brian Bedrosian, Vice President of Marketing for the IoT Compute and Wireless Business Unit at Cypress, added: “The Cypress CYW43012 combo solution continues its forward momentum in the market as OEMs demand key benefits including best-in-class throughput and power efficiency. Our collaboration with Murata in integrating the CYW43012 delivers a compact, pre-tested solution that has helped position Cypress as the supplier of choice for OEMS delivering high performance, long battery-life IoT solutions in applications including cameras, music, healthcare, and security.”

The Type 1LV module is now in mass production.
