CY7C65211A24LQXSXQLA1

Controllers Overview

The CY7C65211A24LQXSXQLA1 is an automotive-grade USB interface integrated circuit manufactured by Infineon Technologies. It functions as a USB data peripheral controller compliant with the USB 2.0 Full-Speed specification, operating at a transfer rate of 12 Mbit/s. The device is housed in a 24-pin QFN package and supports surface-mount installation. It is designed for industrial temperature ranges, typically spanning from -40 °C to +85 °C, with a supply voltage range of 1.71 V to 5.5 V. This component belongs to the EZ-USB Serial Bridge Controller family, providing a single-channel bridge for UART, I2C, or SPI interfaces combined with CAPSENSE capabilities.

Controllers Feature Summary

• Automotive-grade qualification for reliable operation in vehicle environments
• Single-channel USB-to-serial bridge supporting UART, I2C, and SPI protocols
• Integrated CAPSENSE technology for capacitive touch sensing applications
• Built-in Battery Charging Detection (BCD) functionality

Controllers Applications

• Automotive infotainment systems and head units
• Medical and healthcare devices requiring USB connectivity
• Gaming peripherals and networking equipment

Controllers Procurement Notes

Verify the specific suffix XQLA1 against official Infineon documentation to confirm packaging and tape-and-reel specifications. Ensure compliance with RoHS directives and moisture sensitivity levels before integration. Confirm availability status through authorized distributors as stock may be restricted. Validate that the automotive grade meets the required AEC-Q100 standards for the target application environment.

Controllers Selection Notes

Select this component when an automotive-certified USB full-speed peripheral controller is required. It is suitable for designs needing a compact QFN footprint with integrated serial bridging and touch sensing. Compare against non-automotive variants like the CY7C65211A-24LTXIT if environmental ratings differ. Ensure the system power supply aligns with the 1.71 V to 5.5 V operating range.

Controllers Part Context

This part is a variant within the EZ-USB Serial Bridge Controller family, specifically tailored for automotive data applications. It shares core architecture with other CY7C65211 series devices but differs in packaging and automotive qualification. The QFN package offers a small form factor suitable for space-constrained PCB layouts in modern electronic assemblies.

Controllers Replacement Considerations

The CY7C65211A-24LQXSTXUMA1 is a related automotive variant in tape-and-reel packaging. Verify pinout compatibility and software configuration requirements when substituting between tray and reel versions within the same functional family.
