Infineon Technologies AG has announced the company’s new AIROC CYW5591x Connected Microcontroller (MCU) product family.

The new family integrates robust, long-range Wi-Fi 6/6E and Bluetooth Low Energy 5.4 along with a secured and versatile MCU to allow customers to build cost-optimised, power-efficient, small form-factor products for smart home, industrial, wearables, and other IoT applications. The flexible platform accelerates customers’ time-to-market with ModusToolbox  software, RTOS and Linux host drivers, a fully validated Bluetooth stack and multiple sample code examples, Matter software enablement, and support for Infineon’s worldwide partner network.

“As an IoT leader with more than a billion Wi-Fi devices deployed worldwide, Infineon is committed to driving decarbonisation and digitalisation with low-power solutions that connect products to the cloud,” said Sivaram Trikutam, Vice President of Wi-Fi Products, Infineon Technologies. “The combination of our easy-to-use software, along with industry’s best wireless performance and lowest power consumption allows best-in-class IoT products to be built using the AIROC CYW5591x Connected MCU family.”

This flexible device family can be used as the main processor in an IoT device or as a subsystem in more complex designs to fully offload connectivity for IoT applications. The product family is available in 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) support.

Key features

Other key features of the new devices include:

  • An Arm  Cortex  M33 192MHz MCU with TrustZone  CC312 with 768 KB SRAM
