CY7C65223-24LTXI

Controllers Overview

The CY7C65223-24LTXI is an automotive-grade, single-channel USB-UART bridge controller compliant with the USB 2.0 Full-Speed specification (12 Mbps). It features a configurable UART interface supporting data rates up to 3 Mbps and RS232/RS422/RS485 signaling. The device integrates a 48 MHz oscillator, 512-byte flash for configuration storage, and supports software/hardware flow control. Operating voltage ranges from 1.71 V to 5.5 V, with an extended temperature range of -40°C to 105°C.

Controllers Feature Summary

• Supports RS232, RS422, and RS485 serial interfaces with configurable data formats and parity options.
• Integrates Battery Charger Detection (BCD) compliant with USB battery charging specification rev. 1.2.
• Includes internal flash memory for storing VID, PID, and unique serial numbers to fix COM port assignments.

Controllers Applications

• Automotive infotainment systems
• Medical and healthcare devices
• Point-of-Sale (POS) terminals
• Test and measurement systems

Controllers Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel versus tray packing configurations. Ensure the selected variant meets the required operating temperature grade for your application environment. Cross-reference the ordering code with the manufacturer's current product status to confirm availability and lifecycle stage before finalizing procurement plans.

Controllers Selection Notes

Select this component when an automotive-grade USB-to-serial bridge with RS485 support is required. Verify that the 4 GPIO pins meet interface needs or can be repurposed if using minimal UART pin counts. Confirm compatibility with the Windows configuration utility for setting custom descriptors and BCD parameters during system integration.

Controllers Part Context

This part belongs to the EZ-USB Serial Bridge Controller family, designed for legacy peripheral connectivity without firmware development. Unlike lower-pin-count variants, it specifically targets automotive environments with extended temperature ratings. It serves as a drop-in replacement for standard USB-UART controllers in applications requiring robust serial communication over USB.

Controllers Replacement Considerations

CY7C65223-24LQXS: Identical functional specifications; verify packaging differences such as tray versus tape-and-reel delivery methods.

Controllers FAQ

Does the CY7C65223 support hardware flow control?

Yes, the device supports both software flow control (XON/XOFF) and hardware flow control using RTS#/CTS# signal pairs.

What is the maximum UART baud rate supported?

The UART interface supports asynchronous serial communication with data rates up to 3 Mbps.

Can the COM port number be fixed permanently?

Yes, the device supports a unique serial number feature that allows the COM port number to remain constant when plugged into a PC as a CDC device.
