CY7C65213-32LTXI

Controllers Overview

The CY7C65213-32LTXI is a USB-to-UART bridge controller manufactured by Cypress Semiconductor. It integrates a USB 2.0 Full-Speed (12 Mbps) controller, UART transceiver, internal regulator, oscillator, and 512-byte flash within a 32-pin QFN package. The device supports data rates up to 3 Mbps with 256-byte transmit and receive buffers. It accommodates 2, 4, 6, or 8-pin UART configurations and handles parity, overrun, and framing errors. The component enables UART-based devices to interface with USB hosts using minimal external components.

Controllers Feature Summary

• Integrates USB 2.0 Full-Speed controller with UART transceiver and internal memory for descriptor storage
• Supports configurable UART interfaces including RS232 and RS422 signaling modes
• Includes built-in Virtual COM Port drivers for simplified PC application integration

Controllers Applications

• Upgrading legacy UART-based hardware to USB connectivity
• Industrial automation serial communication gateways
• Embedded system debugging and programming interfaces

Controllers Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature range. Ensure compatibility with required USB descriptors stored in the internal flash. Confirm that the single-channel RS232/RS422 support meets the target application's signal requirements rather than assuming broader protocol support.

Controllers Selection Notes

Select this model when a compact solution is needed to bridge UART peripherals to USB without external crystals or regulators. Verify that the 512-byte flash capacity suffices for custom vendor descriptors. Consider the CY7C65213A variant if RS485 multi-drop communication is required, as the base model does not support that protocol.

Controllers Part Context

This component belongs to the Cypress USB-UART LP Bridge Controller family. It serves as a drop-in replacement for older discrete USB-to-serial chips, reducing bill-of-materials count. The device is part of Cypress's broader portfolio of connectivity solutions designed for embedded systems requiring reliable serial data transfer over USB buses.

Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in verified documentation.
