• Includes Battery Charging Detection (BCD) functionality to manage power source identification.
• Provides up to 12 general-purpose input/output pins for flexible system interfacing.
• Features ultra-low power consumption with a standby current specification of 5 uA.

Controllers Applications

• Automotive infotainment systems requiring USB-to-serial bridging.
• Industrial networking equipment utilizing USB peripherals.
• Medical and healthcare devices needing reliable serial communication interfaces.

Controllers Procurement Notes

Verify the specific suffix 'STXUMA1' against official Infineon documentation to confirm automotive qualification and tape-and-reel packaging specifications. Ensure compatibility with AEC-Q100 requirements for your target application environment. Cross-reference the Mouser part number 726-CY7C65211A24LTIT if alternative availability is required, noting potential differences in packaging or regional distribution status.

Controllers Selection Notes

Select this component when designing automotive or industrial systems that require a compact USB-to-UART/I2C/SPI bridge solution. The inclusion of CAPSENSE and BCD features makes it suitable for applications integrating user interface controls and power management without additional discrete components. Consider the 24-pin QFN footprint for PCB layout constraints and verify thermal dissipation requirements for the intended operating temperature range.

Controllers Part Context

This part belongs to the EZ-USB Serial Bridge Controller family, specifically the CY7C65211 series. It serves as a specialized variant optimized for automotive environments, distinguishing itself from standard commercial versions through enhanced reliability testing and qualification processes. The device complements other Infineon interface solutions by providing a complete USB peripheral controller with embedded sensing and charging detection capabilities.

Controllers Replacement Considerations

The CY7C65211-24LTXI is a commercially graded equivalent within the same product family. Verify if automotive qualification is strictly required before substituting, as the base model lacks specific automotive certifications. Both parts share identical functional pinouts and core specifications.
