CY7C68300C-56LTXC USB 2.0 ATA Bridge | Infineon
Référence : CY7C68300C-56LTXC ✓ ActifCY7C68300C-56LTXC Présentation
A USB-to-ATA bridge is an interface controller that translates USB transactions into ATA and ATAPI commands. It sits between a USB host and a disk drive or storage subsystem, allowing equipment that lacks a native ATA interface to communicate with conventional mass-storage devices. Within the hierarchy of USB interface controllers, the CY7C68300 family belongs to the broader category of USB-to-storage bridge controllers and mass-storage interface semiconductors.
The CY7C68300C-56LTXC supports USB 2.0 full-speed and high-speed operation, ATA/ATAPI bridging, and a 3.3 V supply. The commercial-temperature ordering code corresponds to an operating range of 0°C to 70°C. The 56-pin QFN package exposes a high number of ATA data, control, and power connections while maintaining a compact board area suitable for portable storage products. The exposed thermal pad also provides a direct heat-transfer path into the PCB copper plane.
Typical uses include USB external enclosures, personal-media players, portable disk systems, industrial data-acquisition equipment, and embedded ATA storage. The bridge is most appropriate when an existing USB host must communicate with an ATA or ATAPI peripheral through a cable rather than mounting the drive directly on a host bus. Its design converts a general-purpose USB connection into the command and data protocol expected by the storage device.
Circuit design should preserve the voltage, signal-integrity, and decoupling requirements specified by the manufacturer datasheet. The ATA interface is a high-speed parallel bus, so controlled impedance routing, short point-to-point connections, solid ground-plane continuity, and careful separation between sensitive supply paths and fast data lines are essential. Place the required input, output, and interface capacitors close to their associated pins, and connect the exposed pad to the recommended ground-plane construction.
This product page combines the exact ordering information, package details, and verified listing links for CY7C68300C-56LTXC with practical USB-to-ATA implementation guidance. It also identifies the confirmed same-family alternatives that can support sourcing evaluation while emphasizing that firmware support, ATA protocol details, exposed-pad layout, and signal timing must be checked before any replacement is approved.

Applications typiques
CY7C68300C-56LTXC convient pour 6 applications: USB External Storage Enclosure, Portable Media Player, Industrial Data Acquisition, Embedded ATA Storage Controller, USB Card Reader and Media Adapter, Test and Measurement Data Storage.
USB External Storage Enclosure
The CY7C68300C-56LTXC fits a USB storage enclosure that connects an ATA or ATAPI disk drive to a computer or host controller. Its USB 2.0 full-speed and high-speed operation provides the appropriate host-facing interface, while the 3.3 V supply matches modern USB storage electronics. Place the controller and storage interface on a controlled-impedance PCB, follow the manufacturer capacitor placement guidance, and provide a continuous ground plane beneath the 56-QFN. Verify drive power-on behavior, cable shielding, connector grounding, and operating-system media-access compatibility before production.
Recommandé
Portable Media Player
The CY7C68300C-56LTXC can serve as the USB-to-storage interface in a portable media player that exposes ATA memory to a USB host. Its full-speed/high-speed USB 2.0 support and 56-pin QFN construction make it suitable for compact embedded equipment, while the 8 mm by 8 mm package preserves board area. The 0°C to 70°C commercial range is appropriate for typical indoor portable products. Account for enclosure heat buildup, connector insertion forces, ESD protection, and the precise exposed-pad and capacitor layout prescribed by the manufacturer datasheet.
Recommandé
Industrial Data Acquisition
The CY7C68300C-56LTXC is applicable to industrial data-acquisition equipment that records information to ATA or ATAPI storage while presenting a USB interface to a host computer. USB 2.0 full-speed and high-speed modes support standard removable or embedded storage workflows, and the 3.3 V operating supply simplifies integration with contemporary controller logic. Design the ATA segment for controlled impedance and minimize stubs, keep the exposed pad thermally coupled to solid ground copper, and validate file-system behavior, write reliability, and bus compatibility across the full intended operating range.
Recommandé
Embedded ATA Storage Controller
The CY7C68300C-56LTXC can bridge an embedded ATA/ATAPI storage device to a USB host in appliances, test systems, and compact embedded platforms. The controller separates the storage bus from the host-facing USB interface, reducing the need for a host processor to implement ATA protocol handling directly. Because the bridge depends on precise timing, supply integrity, and media-access behavior, route the high-speed parallel ATA signals on a controlled-impedance board and confirm device firmware support for the selected media before design freeze.
Recommandé
USB Card Reader and Media Adapter
The CY7C68300C-56LTXC can support a USB storage adapter that connects an ATA/ATAPI device to a host over USB 2.0. Its full-speed and high-speed operation covers standard USB storage transfers, while the compact QFN-56 package provides numerous ATA and control connections in an 8 mm by 8 mm area. Use the manufacturer pin description to assign ATA data, control, power, and ground functions, and maintain short return paths and stable decoupling. Media-format support and enumeration behavior should be verified with every intended drive or memory configuration.
Recommandé
Test and Measurement Data Storage
The CY7C68300C-56LTXC can provide USB-to-ATA storage connectivity in test and measurement equipment that retains large captured datasets on conventional disk media. USB 2.0 high-speed operation is suited to bulk storage transfers, while the ATA/ATAPI side supports connection to compatible storage devices. In a high-density instrument, prioritize uninterrupted ground planes, controlled-impedance ATA routing, and the specified 3.3 V decoupling. Confirm sustained-transfer behavior, media power requirements, and thermal performance inside the enclosure before production testing.

Notes de conception
Use the manufacturer land pattern and exposed-pad instructions exactly, because the 56-pin QFN requires a dedicated copper connection rather than a simple pad-by-pad footprint. Extend the exposed pad into the ground plane with multiple short thermal vias where the datasheet permits, and preserve pin 1 orientation using the package marking. Confirm paste-release behavior and solder-reflow profile during assembly qualification.
Treat the ATA interface as a high-speed parallel bus. Use a continuous reference plane, avoid splits beneath data nets, keep device-to-connector traces short, and match impedance according to the board stack-up and the manufacturer interface requirements. Place termination or damping components only where the reference design and signal-integrity analysis support them; incorrect source termination can reduce the usable rise and fall-time margin.
Implement the 3.3 V supply with the decoupling values and placement specified by the manufacturer datasheet. Keep each capacitor adjacent to its intended power pin, use a low-impedance ground return, and isolate the controller's switching and interface currents from sensitive analog circuitry. Check the inrush and operating-current behavior of the attached ATA drive because storage-media startup can create a load step much larger than the bridge controller's own consumption.
