Infineon AIROC™ CYW5551x Series Wi-Fi 6/6E and Bluetooth® 6.0 Solution

High performance wireless connectivity on a single chip

Infineon’s AIROC™ CYW5551x series brings the advanced features of Wi-Fi® 6 and Bluetooth® Low Energy 6.0 together in a single-chip solution, available in easy-to-integrate modules from Murata and Ezurio.

The AIROC CYW5551x chipsets are designed for reliable, high-performance wireless communication in space- and power-constrained applications such as IoT devices, smart home products, and wearables. These chips exceed the Wi-Fi 6/6E standard, enabling faster data transfers and improved performance in congested network environments.

The series includes three variants:

  • CYW55513 (tri-band 2.4 GHz / 5 GHz / 6 GHz)
  • CYW55512 (dual-band)
  • CYW55511 (single-band)

Each integrates an IEEE 802.11ax-compliant Wi-Fi 6/6E transceiver and Bluetooth/Bluetooth Low Energy (LE) v5.4 subsystem. A 192 MHz Arm® Cortex®-M33 processor handles Bluetooth system control and supports both hosted/controller and embedded Bluetooth operating modes.

Two module options are available:

  • Murata Type 2FY (LBEE5HY2FY-922): ultra-compact for power- and space-sensitive industrial applications (up to 85°C)
  • Ezurio Sona™ IF513 (453-00195): industrial-grade module with SDIO/UART interfaces, offered in pluggable card and SMT M.2 formats
