Infineon Technologies expands its AIROC Wi-Fi 6/6E portfolio with the powerful CYW5591x family of wireless microcontrollers

[Munich, Germany, June 28, 2024] Infineon Technologies AG, a global semiconductor leader in power systems and the Internet of Things, recently launched the new AIROC™ CYW5591x wireless microcontroller (MCU) product series . The new series integrates powerful long-range Wi-Fi 6/6E with low-power Bluetooth 5.4 and secure multi-function MCUs, enabling customers to create lower-cost, energy-efficient, and small-size products for smart homes, industries, wearables, and other IoT applications. The platform is highly flexible and can speed up the time to market for customer products. This is inseparable from Infineon's ModusToolbox™ software, RTOS and Linux host drivers, fully verified Bluetooth protocol stacks and multiple sample codes, support for Matter software, and support from Infineon's global partners.

CYW5591x Wireless MCU

“As a semiconductor leader in the IoT, with more than 1 billion Wi-Fi devices deployed worldwide, Infineon is committed to driving decarbonization and digitalization with low-power solutions that connect products to the cloud,” said Sivaram Trikutam, Vice President Wi- Fi Products at Infineon Technologies AG. “Customers can create best-in-class IoT products with the AIROC™ CYW5591x wireless MCU family, thanks to our easy-to-use software, industry-leading wireless performance and very low power consumption.”

This flexible wireless MCU family can be used as the main processor of an IoT device or as a subsystem in a more complex design to provide wireless connectivity for IoT applications. The family currently has three versions: CYW55913 for tri-band (2.4/5/6 GHz), CYW55912 for dual-band (2.4/5 GHz) and CYW55911 for single-band (2.4GHz).

Main Features

Other key features of the new product line include:
