A USB-to-ATA bridge is a controller within the USB interface-controller and mass-storage interface hierarchy. Its purpose is to translate USB host transactions into ATA or ATAPI commands for compatible storage devices. This USB-to-ATA bridge category falls under interface ICs, semiconductor controllers, and data-transfer interface devices. Such controllers are used to connect external storage hardware to a USB-capable computer, embedded system, or portable electronics platform without requiring a conventional internal storage interface.
The CY7C68301B family supports USB 2.0 mass-storage applications and is offered in lead-free 56-pin SSOP and 56-pin QFN package options. The CY7C68301B-56PVXC is the SSOP configuration, while the separate -56LFXC ordering code identifies a QFN package. Its USB 2.0 ATA-interface positioning makes it suitable for portable and embedded storage equipment requiring a host-side USB connection to an ATA or ATAPI-compatible drive.
The controller is intended for ATA/ATAPI-6 compliant mass-storage devices, including portable storage applications associated with battery-powered designs. A typical system places the bridge between a USB connector and an ATA-compatible drive interface, allowing a USB host to enumerate and transfer data to the attached storage device. The 56-pin SSOP package supports compact, surface-mount assembly while providing enough pins for the USB, ATA, storage-interface, clock, power, and configuration functions defined by the family.
Potential uses include USB-connected portable drives, card-reader systems, embedded data loggers, industrial storage equipment, and legacy ATA storage adapters. Because it targets ATA and ATAPI storage rather than modern SATA or NVMe interfaces, system compatibility must be confirmed before deployment. The bridge should also be checked against the host operating system, drive interface, power requirements, and required USB enumeration behavior.
A key design consideration is that the -56PVXC and -56LFXC suffixes identify different package constructions rather than electrically identical drop-in land patterns. Confirm the mechanical drawing, pin assignment, PCB footprint, and exposed or non-exposed package details before schematic capture. Review the manufacturer pin-description table when assigning ATA signals, USB data lines, control inputs, and supply pins.
This page consolidates the verified USB 2.0 ATA-interface description, package distinctions, related controller options, and design guidance into an engineer-focused component reference. It also distinguishes same-footprint family alternatives from QFN variants and separates documented specifications from parameters that still require confirmation against the manufacturer datasheet.

典型應用
CY7C68301B-56PVXC 適用於 6 應用s: Portable USB Mass-Storage Adapter, ATA-Compliant Data Logger, Embedded Industrial Storage Controller, USB Card-Reader System, USB-to-ATA Legacy Storage Bridge, Battery-Powered Portable Media Device.
Portable USB Mass-Storage Adapter
The CY7C68301B-56PVXC fits a portable adapter that exposes an ATA/ATAPI-compatible drive through USB 2.0. Its 3.3 V nominal supply and 3.15 V to 3.45 V operating range align with compact battery-powered equipment, while the 56-pin SSOP supports surface-mount assembly. The bridge handles the command translation between the USB host and ATA device, avoiding a separate host-side storage controller. Validation should cover enumeration, suspend and resume behavior, cable detachment, and drive-power sequencing under battery discharge conditions.
推薦
ATA-Compliant Data Logger
A data logger can use the CY7C68301B-56PVXC to connect a removable ATA or ATAPI-6 storage device to a USB 2.0 host. The bridge's 56-pin SSOP package permits a compact interface section, while its USB 2.0 to ATA translation provides a practical path for field retrieval of recorded data. Because the design must tolerate repeated insertion and removal, firmware and electrical validation should include hot-plug behavior, write-caching reliability, bus-power availability, and recovery after an unexpected host shutdown.
推薦
Embedded Industrial Storage Controller
The CY7C68301B-56PVXC can bridge an ATA-compatible disk to a USB 2.0 service or configuration port in embedded industrial equipment. Its documented 3.3 V operation and 56-pin SSOP outline support controlled compact layouts, while USB connectivity simplifies maintenance access and data transfer. An industrial implementation should verify operating-temperature limits, brownout behavior, electromagnetic compatibility, grounding, and the ATA signal integrity of the implemented topology before production release.
推薦
USB Card-Reader System
A legacy card-reader or removable-media system can use the CY7C68301B-56PVXC when its storage interface is ATA/ATAPI rather than SATA or NVMe. The controller provides the USB 2.0 bridge between the host and an ATA-compliant device, making it appropriate for equipment designed around older removable-disk architectures. Firmware must support the device class, media-change behavior, and media insertion sequence expected by the host. The 56-pin SSOP footprint also allows reuse of an existing USB-to-ATA circuit board.
推薦
USB-to-ATA Legacy Storage Bridge
The CY7C68301B-56PVXC is useful in a legacy-storage bridge that connects an ATA/ATAPI-6 device to a USB 2.0 host. This application preserves the mechanical and electronic interface of an established ATA product while adding a modern external connection. The 3.15 V to 3.45 V operating range and 56-pin SSOP package align with compact bridge boards. Engineering validation should include drive identification, command timing, power consumption, connector shielding, and compatibility with current host operating systems.
推薦
Battery-Powered Portable Media Device
Battery-powered media equipment benefits from the CY7C68301B family because the CY7C68301B-56PVXC is specifically identified for battery-powered designs. Its 3.3 V nominal operation and low-voltage 3.15 V to 3.45 V range permit integration with a regulated portable power rail, and the 56-pin SSOP supports compact board construction. The bridge connects a compatible ATA/ATAPI storage device to a USB 2.0 host. Power-budget analysis should include drive startup current, USB suspend current, regulator dropout, and the controller's own operating consumption.

主要差異化特點
- Battery-powered design focus within the USB-to-ATA bridge family (對比CY7C68300B-56PVXC)
- Native 56-pin SSOP package (對比CY7C68301B-56LFXC)
- ATA/ATAPI-6 mass-storage positioning (對比CY7C68320B-56PVXC)
設計說明
Confirm the SSOP mechanical drawing before releasing the PCB footprint, and do not substitute the 56LFXC QFN land pattern. Place the controller and its required support components close to the associated ATA and USB routing regions. Keep USB differential routing away from drive power converters and high-current motor or spindle paths to reduce susceptibility to switching noise and ground bounce.
Use the documented 3.15 V to 3.45 V operating range to size the 3.3 V supply. Estimated power-budget review: calculate the bridge dissipation from the actual supply voltage, output current, and efficiency, then add the attached drive's startup demand rather than its average current. Battery-powered equipment must prevent the drive and bridge loads from forcing the supply below the lower operating limit.
Do not treat a 56-pin SSOP controller as interchangeable with a 56-pin QFN controller merely because both have 56 leads. Verify pin numbering, ATA signal mapping, USB data routing, configuration straps, clock requirements, and exposed-pad or thermal-land details. Also confirm that the target system uses ATA or ATAPI storage rather than SATA or NVMe before designing the connector and storage interface.
Implement the USB differential pair as a controlled-impedance route on a continuous reference plane, and keep return-path discontinuities away from the connector and bridge. Provide the decoupling and clock components at the locations specified by the manufacturer application schematic. ATA traces attached to storage devices should be checked for length mismatch, ringing, and coupling from adjacent switching circuitry.
合規資訊
The manufacturer datasheet listing identifies lead-free 56-pin SSOP and QFN package options. RoHS, REACH, halogen-free, and conflict-minerals status require confirmation from the current manufacturer product documentation.
