CY7C68320C-56LTXC

Controllers Overview

The CY7C68320C-56LTXC is a USB high-speed peripheral controller from the EZ-USB AT2LP family, manufactured by Infineon Technologies. It integrates an 8051 microcontroller core with dedicated USB 2.0 High-Speed (480 Mb/s) interface logic. The device operates within a supply voltage range of 3 V to 3.6 V and draws approximately 50 mA during operation. Designed for surface-mount installation, it is housed in a 56-pin VFQFN package with exposed pad. The component supports an operating temperature range from 0°C to +70°C and complies with RoHS standards.

Controllers Feature Summary

• Integrates an 8051 microcontroller core with USB 2.0 High-Speed PHY for direct peripheral control
• Supports bulk, interrupt, and isochronous data transfer modes via standard USB endpoints
• Features programmable I/O ports and DMA channels for efficient data handling without CPU intervention

Controllers Applications

• High-speed USB storage devices such as flash drives and external SSDs
• USB-to-ATA/ATAPI bridge controllers for hard disk and optical drive interfaces
• Custom USB peripherals requiring embedded processing capabilities

Controllers Procurement Notes

Verify component authenticity through authorized distributors or original manufacturer channels due to end-of-life status. Confirm moisture sensitivity level handling requirements prior to assembly. Check for specific revision markings on the package to ensure compatibility with existing design files. Request lot traceability documentation for quality assurance purposes before final procurement decisions.

Controllers Selection Notes

Select this model when a combined MCU and USB HS controller is required in a compact QFN footprint. Compare against the CY7C68013A series if lower pin counts or different packaging are preferred. Ensure the application does not require Low-Speed or Full-Speed only operation, as this part is optimized for High-Speed performance. Verify that the 56-pin thermal pad design fits the target PCB layout constraints.

Controllers Part Context

This component belongs to the EZ-USB AT2LP family, which succeeded earlier FX2LP variants. It was originally developed by Cypress Semiconductor Corp before the company's acquisition by Infineon Technologies. The CY7C68320C variant specifically targets storage bridge applications, differing from general-purpose USB controllers by including optimized ATA command translation logic within the firmware architecture.

Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Due to the End-of-Life status indicated for related models in the same series, alternative sourcing may require checking distributor surplus stocks or evaluating newer generation USB controllers from Infineon.
