CY7C65221-24LTXIT

Controllers Overview

The CY7C65211-24LTXIT is a USB-Serial single-channel bridge controller from Infineon Technologies, operating at Full-Speed (12 Mbps) compliant with USB 2.0 standards. It integrates UART, I2C, and SPI interfaces within a 24-pin QFN package. The device supports configurable data rates up to 3 Mbps for UART and includes Battery Charger Detection (BCD) per USB BC 1.2 specifications. It features an integrated 48-MHz oscillator, 512-byte flash memory for configuration storage, and CAPSENSE™ capabilities for up to five buttons. Operating voltage ranges from 1.71 V to 5.5 V, with industrial temperature support from -40°C to 85°C.

Controllers Feature Summary

• Integrates a single-channel serial communication block supporting configurable UART, I2C, and SPI protocols.
• Includes Battery Charger Detection (BCD) functionality compliant with USB Battery Charging Specification Rev 1.2.
• Features integrated CAPSENSE™ technology allowing smart sensing algorithm auto-tuning without manual calibration.
• Provides ten general-purpose input/output (GPIO) pins with flexible configuration options including LED driving and power control.

Controllers Applications

• Medical and healthcare devices requiring USB connectivity
• Point-of-sale (POS) terminals and gaming systems
• Industrial automation and networking equipment
• Enabling USB connectivity in legacy peripherals

Controllers Procurement Notes

Verify the specific ordering suffix 'T' indicates tape-and-reel packaging when sourcing this component. Confirm that the base model CY7C65211 matches the required interface capabilities, noting that the 'A' variant adds RS485 support if needed. Ensure compatibility with the Windows configuration utility for VID/PID customization before finalizing procurement orders.

Controllers Selection Notes

Select the CY7C65211-24LTXIT for applications requiring a single-channel bridge with integrated CAPSENSE™ and BCD. Choose the CY7C65211A variant if RS485 interface support is necessary, as the standard CY7C65211 does not support it. Consider the 24-pin QFN package dimensions for PCB layout constraints and verify thermal requirements for the specified operating temperature range.

Controllers Part Context

This component belongs to the EZ-USB Serial Bridge Controller family by Infineon Technologies. It serves as a cost-effective solution for adding USB connectivity to serial peripherals. The series includes variants like the CY7C65213 and CY7C65223, which offer different channel counts or interface specializations such as LP bridges or automotive-grade certifications.

Controllers Replacement Considerations

The CY7C65211A-24LTXI is a functional alternative within the same family but includes RS485 support. Verify pinout compatibility and software driver availability when substituting. No other direct cross-model replacements are confirmed in public documentation.
