CY7C68301C-56PVXC

Controllers Overview

The CY7C68301C-56PVXC is a fixed-function USB 2.0 to ATA/ATAPI bridge controller from the EZ-USB AT2LP family, manufactured by Cypress Semiconductor. It operates at High Speed (480 Mbps) or Full Speed (12 Mbps) and supports ATA/ATAPI-6 compliant mass storage devices. The device features a 4 KB FIFO buffer, requires no firmware, and utilizes an external serial EEPROM for configuration. It supports PIO Modes 0, 3, and 4, Multiword DMA Mode 2, and UDMA Modes 2, 3, and 4. The component is housed in a 56-pin SSOP package and is designed for battery-powered applications.

Controllers Feature Summary

• Fixed-function architecture eliminating the need for custom firmware development
• Supports both self-powered and USB bus-powered operational modes
• Backward pin-compatible with the legacy EZ-USB AT2 (CY7C68300A)
• Compliant with USB Mass Storage Class Bulk-Only Transport specification

Controllers Applications

• Bus powered Compact Flash readers
• Portable USB hard drives
• ATA/ATAPI to USB bridges for CD/DVD drives
• MP3 players and personal media players

Controllers Procurement Notes

Verify the specific suffix PVXC confirms the 56-pin SSOP Pb-free package type. Confirm the manufacturer origin as Cypress Semiconductor or Infineon Technologies, noting that Cypress was acquired by Infineon. Ensure the component meets RoHS compliance standards required for modern electronics manufacturing.

Controllers Selection Notes

Select this model over the CY7C68300C variant when the design specifically targets battery-powered applications due to optimized power characteristics. Ensure the design accommodates the 56-pin SSOP footprint and includes provisions for an external serial EEPROM to store USB descriptors and device configuration data.

Controllers Part Context

This component belongs to the EZ-USB AT2LP series, which serves as a cost-effective replacement for older ISD-300A1 and EZ-USB AT2 designs. It provides a direct migration path for existing hardware while adding support for high-speed USB 2.0 transfers and improved power management capabilities compared to its predecessors.
