Controllers Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to ensure correct package type and temperature grade. Confirm that the component meets RoHS compliance requirements for your target market. Cross-reference the datasheet revision history to ensure compatibility with existing design files and driver libraries.

Controllers Selection Notes

Select this component when a single-channel USB-to-serial bridge with integrated touch sensing is required. Ensure the application utilizes UART, SPI, or I2C protocols within the specified speed limits. Verify that the system power budget accommodates the operating voltage range and current consumption profiles defined in the electrical specifications.

Controllers Part Context

This part belongs to the EZ-USB Serial Bridge Controller series designed for legacy peripheral connectivity. It serves as a bridge between USB hosts and serial devices without requiring complex firmware development on the host side. The device simplifies integration by providing pre-certified USB drivers and a configuration utility for parameter customization.

Controllers Replacement Considerations

The CY7C65211A-24LTXI is a functional variant within the same package offering RS485 support. Verify if the additional RS485 capability is necessary for the design. Other members of the EZ-USB Serial Bridge family may offer different channel counts or interface combinations but require separate validation.
