Infineon Technologies AIROC™ CYW55913/2/1 Connected Microcontrollers

Infineon Technologies AIROC™ CYW55913/2/1 Connected Microcontrollers (MCUs) 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® Low Energy 5.4. The devices support a 192MHz Arm® Cortex®-M33 processor with Arm TrustZone® CC312, and include 768KB of SRAM, featuring a QSPI interface for expanding Flash and PSRAM with eXecute-in-place (XIP) and on-the-fly (OTF) encryption and decryption. The Infineon Technologies CYW55913/2/1 offers the best-in-class Wi-Fi range and features Bluetooth Low Energy 5.4, supporting long-range connectivity. The devices are intended to be the primary MCU in the system, or to offload a host processor from Wi-Fi and networking functions.
