CY7C68300C-56LFXC - USB 2.0 ATA Bridge | Infineon
Teilenummer: CY7C68300C-56LFXC ✗ AbgekündigtCY7C68300C-56LFXC Übersicht
A USB-to-ATA bridge is an interface controller that bridges the protocol and electrical differences between USB and ATA storage. USB provides a host-controlled peripheral connection, while ATA/ATAPI is used with compatible storage devices. This bridge controller therefore belongs to the broader USB interface IC and data-transfer controller hierarchy, reducing the need for a host system to implement the storage-facing protocol directly.
The principal specifications are its USB 2.0 interface support, ATA/ATAPI bridge function, 3.15 V to 3.45 V operating supply range, 50 mA operating supply current, and 56-QFN-EP surface-mount package. The compact 8 mm by 8 mm outline supports space-conscious USB storage equipment, while the exposed pad provides the thermal and electrical connection required by the package construction.
The C revision is associated with the EZ-USB AT2LP family of USB-to-ATA storage controllers. The available product records identify the same USB 2.0 ATA-interface function for CY7C68300C and CY7C68301C, while CY7C68300B is described as a low-power USB peripheral variant. These family comparisons are useful for revision and sourcing reviews, but detailed differences in clocking, signaling, and feature support should be checked against the relevant manufacturer datasheet before a replacement is approved.
Typical applications include USB-connected hard-disk and removable-storage systems, ATA/ATAPI storage adapters, embedded data-logging equipment, and legacy computer peripherals that require a USB 2.0 storage interface. The 3.15 V to 3.45 V operating range is suitable for regulated 3.3 V system rails, allowing the bridge to share a conventional 3.3 V supply architecture when the complete system design permits it.
The 56-QFN exposed-pad footprint requires careful PCB layout and thermal design. Place the device’s decoupling capacitors close to the supply pins, provide a low-impedance ground connection, and follow the manufacturer’s exposed-pad land-pattern and assembly guidance. Because the recorded operating temperature range is 0 °C to 70 °C, verify the complete enclosure temperature and thermal rise before using the part in industrial or automotive environments.
This product record combines the USB 2.0 ATA-bridge identity, package data, lifecycle information, cross-reference candidates, and practical design considerations needed for legacy-system review. Because the component is recorded as obsolete, engineers should confirm availability, inspect the original ATA/ATAPI interface requirements, and verify every pin and timing constraint against the manufacturer datasheet before beginning a new design.

Typische Anwendungen
CY7C68300C-56LFXC ist geeignet für 6 Anwendungs: USB 2.0 Hard-Disk Interface, Removable Storage Adapter, Embedded Data-Logging System, Legacy Computer Peripheral, USB Storage Test Equipment, Industrial Retrofit Controller.
USB 2.0 Hard-Disk Interface
The CY7C68300C-56LFXC fits legacy USB-to-ATA storage designs because it bridges a USB 2.0 host connection to an ATA/ATAPI device. Its listed 3.15 V to 3.45 V operating range is centered on a 3.3 V rail, allowing integration with regulated storage-controller power when the board architecture supports that level. The 56-QFN-EP package occupies an 8 mm by 8 mm footprint. During implementation, confirm that the attached disk uses compatible ATA or ATAPI signaling and that the host software supports the bridge. Place the required bypass capacitors close to the device and use the manufacturer exposed-pad land pattern to avoid signal-integrity and thermal problems.
Empfohlen
Removable Storage Adapter
The CY7C68300C-56LFXC can serve as the controller in a removable ATA/ATAPI storage adapter connected through USB 2.0. The bridge function avoids implementing both protocol layers in an external host processor, while the 3.3 V-class operating range supports conventional embedded power rails. The device is supplied in a compact 56-QFN-EP package, but its exposed pad requires careful land-pattern execution and adequate ground-plane continuity. Engineering validation should cover hot-plug behavior, cable noise, power sequencing, and the command set used by the removable medium. Because the lifecycle status is obsolete, the adapter should be treated as a maintenance-oriented design unless an early-production allocation is secured.
Empfohlen
Embedded Data-Logging System
The CY7C68300C-56LFXC is appropriate for a legacy embedded logger that exposes an ATA/ATAPI storage device through USB 2.0 to a host computer. Its 50 mA listed operating current provides a defined starting point for the 3.15 V to 3.45 V supply budget, while the ATA/ATAPI bridge function reduces host-side protocol complexity. The package's exposed thermal pad should be connected according to the manufacturer layout so that power and ground paths remain low impedance. Validation should include sustained write activity, USB suspend and resume behavior, brownout recovery, and error handling for an unexpected removal of the storage medium. A temperature check is required if the logger enclosure can exceed the recorded 0 °C to 70 °C range.
Empfohlen
Legacy Computer Peripheral
The CY7C68300C-56LFXC can bridge a USB 2.0 port to ATA/ATAPI storage in a legacy computer peripheral that lacks a native storage interface. Its operating range of 3.15 V to 3.45 V suits a regulated 3.3 V rail, and the 56-QFN-EP body provides a compact solution for space-constrained boards. The design team must verify USB enumeration, legacy operating-system driver expectations, cable-length behavior, and the electrical requirements of the selected media. Since the component is marked obsolete, preserve the footprint in maintenance revisions and qualify a documented same-package replacement before changing the controller. Do not assume pin compatibility from package identity alone; review all signal assignments in the manufacturer datasheet.
Empfohlen
USB Storage Test Equipment
The CY7C68300C-56LFXC can be used in a USB storage test fixture where a host must exercise an ATA/ATAPI device through a USB 2.0 bridge. Its fixed 3.15 V to 3.45 V supply range and 50 mA operating-current listing simplify initial power planning for a 3.3 V test fixture. The compact 56-QFN-EP package also leaves board space for test connectors and measurement circuitry. Use the manufacturer pinout and exposed-pad guidance when laying out the prototype, and include accessible test points for supply, ground, reference clock, USB, and ATA signals. A production release should compare the exact controller revision with the selected storage media because the available family comparison does not document every timing and feature difference.
Empfohlen
Industrial Retrofit Controller
The CY7C68300C-56LFXC may be used in a retrofit controller that adds USB storage access to older ATA/ATAPI equipment. Its 50 mA listed operating current and 3.15 V to 3.45 V supply range fit a controlled 3.3 V retrofit power plan. Before deployment, verify that the enclosure remains within the recorded 0 °C to 70 °C operating range and account for self-heating around the exposed pad. Because the device is obsolete and documented drop-in candidates have only been identified at family level, maintenance programs should archive the original datasheet and complete a signal-by-signal substitution review. A rugged installation also benefits from careful ground-plane continuity and tested surge, brownout, and USB disconnection behavior.

Designhinweise
Use the manufacturer exposed-pad land pattern and preserve a continuous ground connection beneath the 56-QFN-EP device. Place required bypass capacitors adjacent to the associated supply and ground pins, and route high-speed USB and ATA signals over uninterrupted reference planes. Do not substitute a generic 56-QFN footprint without comparing pad dimensions, exposed-pad geometry, solder-mask clearance, and paste volume.
Calculate junction temperature from actual power dissipation and the PCB-specific thermal resistance rather than assuming the package rating alone. The listed 50 mA operating current applies to the stated 3.15 V to 3.45 V operating condition; actual dissipation also depends on the bridge's internal activity and system power architecture. Verify that the recorded 0 °C to 70 °C operating range is preserved at the hottest internal location.
Do not treat same-package family members as automatic replacements. Before fitting CY7C68301C-56LFXC or CY7C68300B-56LFXC, compare supply pins, clock requirements, USB differential routing, ATA and ATAPI signals, interrupts, programming interface, and reset behavior. Check the manufacturer datasheet for any firmware, driver, or media-command changes that could affect an existing host system.
Keep USB and ATA routing away from noisy power-switching nodes and maintain continuous reference planes beneath high-speed traces. Follow the manufacturer's trace-length, impedance, branch, and connector guidance where specified. Because this is an obsolete legacy interface, validate the complete storage path with the intended cable, connector, enclosure, and storage medium rather than relying only on bench-level controller testing.
Compliance-Informationen
