CYW55573MIFFBGT

RF Transceiver ICS Overview

The CYW55573MIFFBGT is a Wi-Fi 6 Combo System-on-Chip from Infineon's AIROC family, designed for IoT applications. It integrates Wi-Fi 6E (802.11ax) and Bluetooth 6.0 capabilities into a single silicon component. The device supports tri-band operation across 2.4GHz, 5GHz, and 6GHz frequencies with a 1x1 antenna configuration. It features an ARM Cortex-M33 core, 512 KB SRAM, and 2 MB ROM. The chip utilizes SDIO and PCIe interfaces for data transmission and UART/PCM/I2S for Bluetooth connectivity. Operating within a voltage range of 3 V to 4.8 V, it is housed in a compact FCFBGA-289 package measuring 12 x 12 mm with a 0.2 mm pitch, suitable for temperatures between -40 °C and 85 °C.

RF Transceiver ICS Procurement Notes

Verify the specific suffix MIFFBGT against official Infineon documentation to confirm the exact package type and pinout configuration. Ensure compatibility with the target operating system requirements, specifically Linux or Android support as documented. Confirm that the design accommodates the thermal and power specifications associated with the FCFBGA-289 package during integration.

RF Transceiver ICS Selection Notes

Select this component when a combined Wi-Fi 6E and Bluetooth 6.0 solution is required for space-constrained IoT designs. It is appropriate for applications needing tri-band wireless connectivity without external radios. Consider the 1x1 antenna configuration and interface options like SDIO and PCIe when evaluating board layout constraints and system performance needs.

RF Transceiver ICS Part Context

This part belongs to the CYW5557x series, which includes variants such as CYW55571 and CYW55572. These components share the same AIROC architecture but differ in package types and interface configurations. The MIFFBGT suffix specifically denotes the FCFBGA-289 package variant, distinguishing it from WLCSP or WLBGA options available in the broader product line.

RF Transceiver ICS Replacement Considerations

Direct substitutes within the same series include CYW55571MIFFBGT and CYW55572MIFFBGT. Verify functional equivalence regarding interface support and package dimensions before substitution. Cross-model generic features do not guarantee identical performance characteristics.
