Murata Manufacturing Co., Ltd. reported that it collaborated with Cypress Semiconductor Corp. to develop the Type 1LV (CYW43012) solution that the companies say is the lowest power, small form factor Wi-Fi® and Bluetooth® module.
This product improves battery life in wearables, smart home products, and portable audio applications. When comparing Type 1LV (CYW43012) to the previous model, Type 1DX (CYW4343W), power consumption in the new module 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 Wi-Fi 11a/b/g/n/ (11ac Friendly™) +Bluetooth 5.0 module provides data transference rates up to 78Mbps on Wi-Fi and 3Mbps on Bluetooth. The WLAN section supports SDIO v2.0 SDR25 interface and the Bluetooth section supports high-speed 4-wire UART interface and PCM for audio data. In IEEE 802.11ac-friendly mode, the WLAN operation supports MCS8 (256 QAM) in 20MHz channel for data rate up to 78Mbps.
The Type 1LV utilizes sophisticated and enhanced hardware mechanisms and algorithms to ensure that Wi-Fi and Bluetooth coexistence is optimized for maximum performance.
An embedded Ipv6 network stack can be used to keep the host processor in sleep mode while maintaining network connections.
The Type 1LV supports popular processors including PSoC6, i.MX RT, STM32, i.MX, and IP Camera platforms, as well as Linux and RTOS based applications.
Measuring 10.0mm x 7.2mm x 1.4mm, the module operates seamlessly in dual-band networks with increased energy efficiency and enhanced security providing optimal performance in Wi-Fi 5 networks. It will have a reference antennae design for FCC/IC certifications and a CE-conducted test to provide a lower development cost and faster time to market.
In addition to Bluetooth 5.0 2Mbps PHY support, it supports all of optional Bluetooth 4.2 features, LE Secure Connections, LE Privacy 1.2, and LE Data Packet Length Extension.
“Teaming with Cypress allows us to leverage our combined expertise in delivering breakthrough solutions that are game-changers for the market,” said Mehul Udani, Director, Connectivity Solutions for Murata Americas. “Using our proprietary packaging and miniaturization technologies, Murata leads in developing turnkey, transformational tools that ease integration and enable connectivity to help bring IoT to fruition. With this lowest Wi-Fi power module, we now enable a new class of products that were previously designated for Bluetooth.”
“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,” said Brian Bedrosian, Vice President of Marketing for the IoT Compute and Wireless Business Unit at Cypress. “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.”
