CYUSB4011FCAXIXQMA1

Application Specific Microcontrollers Overview

The CYUSB4011FCAXIXQMA1 is a USB interface integrated circuit manufactured by Infineon Technologies, belonging to the EZ-USB FX3S family. It functions as a high-performance USB 3.2 Gen 1 device controller designed for applications requiring 5 Gbps data rates. The component integrates an ARM Cortex-A8 processor core with DMA engines and multiple peripheral interfaces. It operates within a supply voltage range of 1.62 V to 3.63 V and supports industrial temperature ranges from -40°C to +85°C. The device is housed in a 169-ball FBGA package, providing a compact solution for high-speed data transfer requirements.

Application Specific Microcontrollers Feature Summary

• Integrates an ARM Cortex-A8 processor core for efficient data processing and control

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'QMA1' against official Infineon documentation to confirm automotive or extended temperature qualifications if required. Ensure compatibility with the 169-ball FBGA footprint during PCB layout. Confirm RoHS compliance status through the manufacturer's latest product qualification reports before finalizing procurement plans.

Application Specific Microcontrollers Selection Notes

Select this model when a balance between processing power and pin count is needed for USB 3.0 designs. The FX3S series offers lower pin counts compared to the FX3, simplifying board space constraints. Verify that the host system supports USB 3.2 Gen 1 signaling. Consider thermal management requirements given the FBGA package density and operating temperature range.

Application Specific Microcontrollers Part Context

This part belongs to the EZ-USB FX3S family, which serves as a cost-effective alternative to the full-featured FX3 controllers. It retains key USB 3.0 capabilities while reducing complexity for simpler peripheral designs. The FX3S line is widely used in consumer electronics and industrial applications where moderate processing overhead is sufficient for USB bridging tasks.

Application Specific Microcontrollers Replacement Considerations

Direct replacements include other variants within the EZ-USB FX3S family, such as CYUSB4011FCAXI. Cross-family migration to FX3 requires significant schematic and firmware adjustments due to increased pin count and memory resources. Verify pin-to-pin compatibility only if the substitute shares the exact FBGA-169 footprint and electrical characteristics.
