CY7C64345-32LQXCT

Application Specific Microcontrollers Overview

The CY7C64345-32LQXCT is a USB interface integrated circuit belonging to the enCoRe V series. It functions as a Full Speed (FS) USB controller with an integrated M8C microcontroller core. The device features 16 kB of FLASH memory for firmware storage and operates within a 3V to 5.5V supply voltage range. It utilizes surface mount technology in a 32-pin UFQFN package with an exposed pad, suitable for applications requiring compact designs.

Application Specific Microcontrollers Feature Summary

• Integrates an M8C microcontroller core with 16 kB of non-volatile FLASH memory for embedded control logic.
• Supports Full Speed USB communication protocols for peripheral connectivity.
• Provides seamless power switchover capabilities between external and internal power sources.

Application Specific Microcontrollers Applications

• USB peripheral devices requiring embedded control
• Compact USB interface solutions
• Power-sensitive USB applications

Application Specific Microcontrollers Procurement Notes

Verify component authenticity through authorized Infineon distributors or certified partners. Confirm that the specific suffix LQXCT matches the required 32-pin UFQFN package and reel packaging format. Check current availability status as this part may be subject to limited supply conditions or end-of-life notices. Ensure compliance with RoHS directives and moisture sensitivity levels specified in the official datasheet before integration into production lines.

Application Specific Microcontrollers Selection Notes

Select this component when a combined USB controller and microcontroller solution is required in a small form factor. The integrated 16 kB FLASH allows for standalone operation without external memory. Consider the 32-pin UFQFN package constraints for PCB layout. Verify that the Full Speed USB requirement aligns with system bandwidth needs, as this device does not support High Speed transfers.

Application Specific Microcontrollers Part Context

This part belongs to the enCoRe V family of USB controllers from Infineon Technologies. These devices are designed to simplify USB implementation by integrating the controller logic and processing core on a single chip. The CY7C64345 variant specifically targets Full Speed applications, offering a cost-effective alternative to separate MCU and USB controller combinations.

Application Specific Microcontrollers Replacement Considerations

Consult official Infineon documentation for direct pin-to-pin replacements or functional equivalents within the enCoRe series. Verify compatibility regarding package dimensions and electrical characteristics if substituting with other variants such as the CY7C64345-32LQXC.
