Miniature Wi-Fi 6 combo module features integrated antennas

Insight SiP launched its ISP5261 Wi-Fi 6 module at Embedded World 2024. This module acts as a fully functioning Bluetooth LE and Wi-Fi radio node, capable of a long autonomous operation on battery power. It can form the core of an autonomous IoT device needing Bluetooth LE and Wi-Fi connectivity.

This device uses SiP technology to deliver state-of-the-art integration and miniaturisation of RF technologies. It also benefits from the company's proprietary, industry-leading 'antenna-in-package' techniques.

The module is based on NXP Semiconductors RW612 single-chip Wi-Fi/Bluetooth LE/802.15.4 Wireless MCU SoC. It integrates a 32-bit ARM Cortex-M33 CPU running at 260MHz, an additional 4MB of QSPI flash memory, 1.2MB SRAM, and analog and digital peripherals. Its powerful processor and ample memory permit this module to be used as the core of a sophisticated IoT application.

Despite its small size of 12mm x 12mm x 1.8mm, the module integrates decoupling capacitors, 40MHz crystal for Wi-Fi and Bluetooth LE and 32.768kHz crystal for low-power timing, DC-DC converters, RF matching circuits, and a dual-band (2.4GHz and 5GHz) antenna. Therefore, this module offers class-leading performance and miniaturisation.

Low power consumption and advanced power management enable AA batteries to last several months. Wi-Fi communication is compliant with the Wi-Fi Alliance specifications for Wi-Fi 6, including the following protocols: IEEE 802.11ax/ac/n/a/g/b/e/i/k/v/w.

Bluetooth LE connectivity is compliant with Bluetooth 5.4, enabling Long-Range communication. The ISP5261 Bluetooth LE section can be used either in peripheral or central roles and can handle up to 16 simultaneous central/peripheral connections. The Matter and Thread protocols, which enable easy internet access and support for SmartHome applications, are also supported.

The odule features prominent security features, including an ARM TrustZone processor and an NXP Edgelock hardware security module that supports Root of Trust, secure communication, and update verification.

Nick Wood, VP Marketing at Insight SiP, said, "We are delighted to launch this module with the next generation of Wi-Fi 6 and BLE technology. Wi-Fi has diverse uses, but the new Wi-Fi 6 is clearly aimed at IoT applications and use cases. With security built-in, this is a Wi-Fi solution customers can trust."

"Insight SIP's miniature integrate module will bring new opportunities for design to our customers across the industrial and IoT markets," said Larry Olivas, vice president and general manager for Wireless Connectivity Solutions, NXP Semiconductors. "With secure connectivity across the most important protocols, including Thread, Wi-Fi, Bluetooth and Matter, this will help simplify design and reduce the complexity of supporting Matter, making it easier to bring new products to market faster."
