AIROC™ CYW5591x connected MCUs for Healthcare and Industrial Applications
Connected MCU with Wi-Fi 6E tri-band and Bluetooth® Low-Energy 5.4
IoT products for Digital Health and Industrial applications require versatile solutions combining powerful, secure compute & control with high-quality wireless capabilites. These products must perform in challenging environments, ensuring reliable wireless connections on top of a secure platform to run the demanding applications needed for today's advanced use cases.
The AIROC™ CYW55913/2/1 are a family of connected MCUs that support 1x1 single-stream, tri-band (CYW555913), dual-band (CYW55912), and single-band (CYW55911), Wi-Fi 6/6E, IEEE 802.11ax-compliant, supporting up to 1024 QAM (MCS11) in 20MHz channels and Bluetooth® Core 5.4. The devices support a 192 MHz Arm® Cortex®-M33 processor with Arm® TrustZone CC312, and include 768 KB of SRAM, with a QSPI interface for expanding FLASH and PSRAM with eXecute-in-place (XIP) and on-the-fly (OTF) encryption and decryption. CYW55913/2/1 provide best in class Wi-Fi range and features a Bluetooth® Core 5.4 supporting Low Energy (LE) and Long Range. The devices are intended to be the primary MCU in the system, or to offload a host processor from Wi-Fi and networking functions.
The AIROC™ CYW5591x incorporates multi-layer security to protect your device at run time and through whole product life cycle. It supports PSA Level 2, RED and RSA certification to meet the demanding security requirements for Digital Health and Industrial applications.
The CYW5591x provides a fully tested and certified AIROC Bluetooth Stack and example code to shorten development cycle and time-to-market, and with pre-certified modules from third party partners like Ezurio and Azurewave, time-to-market can be further accelerated and development complexity reduced.
