The new AIROC™ CYW5591x Connected MCU product 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-optimized, power-efficient, small form-factor products for smart home, industrial, wearables, and other IoT applications.

The flexible MCU 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 decarbonization and digitalization 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 (2.4 GHz) support.

The CYW5591x includes an Arm ® Cortex ® M33 192 MHz MCU with TrustZone ® CC312 with 768 KB SRAM; quad-SPI with XIP with on-the-fly encryption/decryption for FLASH and PSRAM; up to +24 dBm transmit power for Wi-Fi for best-in-class range, and support for 6 GHz (Wi-Fi 6E) greenfield spectrum for lower congestion and reduced latency.

The devices provide Matter-over-Wi-Fi support as well as hardware support for AES, RSA, ECC, ECDHA, ECDSA, and Root-of-Trust.

The integrated Bluetooth Low Energy 5.4 supports Bluetooth low energy 2 Mbps, LE Long Range, Advertising Extensions, and Advertising code selection for LE Long Range. Bluetooth Low Energy range and power are also optimized with up to +19 dBm transmit power. The devices provide best-in-class LE Long Range sensitivity of -111.5 dBm.

Extensive peripherals and GPIO support includes: 3xSCB(I2C/SPI/UART), TCPWM, 7 channel 12-bit ADC, Digital Microphone support, TCM (I2S/PCM), and up to 47 GPIOs

PSA Level 2 Certifiable, CYW5591x Connected MCU family offer multi-layer security supporting lifecycle management, secured boot with firmware authentication and encryption, anti-rollback, crypto key establishment, and management.

An extensive module and platform partners ecosystem that meet the customers’ specific application requirements is also offered. The CYW55913/2/1 is now sampling to alpha customers.
