CY7C68320-100AXC - USB 2.0 to ATA Bridge | Infineon
MPN: CY7C68320-100AXC ✓ AktifCY7C68320-100AXC Genel Bakış
A USB-to-ATA bridge is a storage-interface controller within the broader USB interface-controller and data-conversion IC hierarchy. Its primary role is to translate USB transactions and descriptors into ATA or ATAPI commands, allowing compatible storage equipment to appear as a USB peripheral. This device class is useful when legacy or removable storage interfaces must be connected through a standardized USB high-speed host port.
The verified listings identify the CY7C68320-100AXC as a Cypress Semiconductor EZ-USB AT2LP USB 2.0 to ATA/ATAPI bridge. Related listings describe the corresponding CY7C68320C-100AXC as a 100-pin USB-to-ATA bridge, providing confirmation of the interface function, family positioning, and package format. The commercial-grade operating-temperature information listed for the closely identified CY7C68320C-100AXC is 0°C to 70°C, while the exact specification for the non-C target order code remains to be confirmed from its manufacturer datasheet.
Architecturally, this controller sits between a USB host and an ATA/ATAPI storage device. USB provides the external connection and enumeration boundary, while ATA commands operate internally through the bridge's ATA-compatible interface. The integration can shorten firmware and hardware development for USB storage products by consolidating protocol handling in a dedicated controller instead of implementing the complete bridge function in a separate microcontroller.
Typical use cases include USB-connected external storage, embedded data-logging systems, industrial storage adapters, legacy ATA equipment modernization, and test fixtures that require a USB front end for an ATA peripheral. In each case, system design must still provide the required USB termination, ATA signal routing, storage connector, power architecture, and firmware support for the selected device configuration.
The primary design consideration is package verification. Distributor records alternate between CY7C68320-100AXC and CY7C68320C-100AXC, and the available search results do not provide a verified pin-by-pin comparison for every order code. Engineers should therefore confirm the exact MPN, pinout, electrical limits, supported ATA modes, and firmware compatibility against the applicable manufacturer datasheet before releasing a PCB or production order.
This page consolidates verified distributor and manufacturer-document discovery records with package-aware selection guidance, practical integration considerations, and an explicit separation of confirmed facts from unresolved data. It is intended to accelerate engineering review while avoiding unsupported claims about lifecycle, pricing, pin assignments, or drop-in substitution.

Tipik Uygulamalar
CY7C68320-100AXC için uygundur 6 uygulamas: USB External Storage Adapter, Industrial Data Logging, Legacy ATA Equipment Modernization, USB Storage Test Fixture, Embedded Portable Storage, USB-to-ATA Storage Adapter.
USB External Storage Adapter
The CY7C68320-100AXC fits a USB-to-ATA storage adapter because it provides a dedicated USB 2.0 high-speed bridge and ATA/ATAPI interface in a 100-LQFP package. According to the verified product description, the device implements the EZ-USB AT2LP USB-to-ATA function, allowing a USB host to communicate with a compatible storage peripheral without implementing the entire protocol bridge in an external microcontroller. The resulting USB 2.0 link has a maximum signaling rate of 480 Mbit/s, although real transfer speed remains constrained by the attached ATA device, command latency, firmware, and host overhead. Before layout release, verify the exact order-code revision, pin assignments, required external components, and firmware support against the applicable manufacturer documentation.
Industrial Data Logging
The CY7C68320-100AXC is appropriate for industrial data-logging equipment that stores records on an ATA-compatible drive while presenting a USB interface to a host computer. Its verified USB 2.0 to ATA/ATAPI bridging function separates the external storage protocol from the logging application and avoids building a complete USB storage controller around a separate microcontroller. The 100-LQFP package provides enough pin count for the USB, ATA, control, and supporting interface signals required by this bridge class. At the 480 Mbit/s maximum USB high-speed rate, sustained logging performance will usually be governed by the slower storage media and host stack. Designers should also plan power-loss protection, write-cache behavior, enclosure grounding, and operating-system driver validation.
Legacy ATA Equipment Modernization
The CY7C68320-100AXC can bridge legacy ATA equipment to a modern USB host, which makes it useful for instrument upgrades, factory-floor retrofits, and specialized data-acquisition systems. According to the verified indexed datasheet, the EZ-USB AT2LP family translates USB transactions into ATA and ATAPI commands, providing a defined interface between two different bus families. The target's 100-LQFP package is intended for surface-mount PCB integration rather than simple adapter construction. Because legacy storage may use older modes, timing margins, or connector wiring, engineers must confirm supported ATA modes, media behavior, and firmware requirements. A controlled migration plan should include prototype testing, brownout analysis, connector shielding, and long-duration read/write qualification.
USB Storage Test Fixture
The CY7C68320-100AXC can be used in a USB storage test fixture that exposes an ATA peripheral to a host computer for validation, recovery, or production testing. The verified listings identify the controller as a USB 2.0 to ATA/ATAPI bridge, enabling test software to access a removable or embedded drive through a standard USB connection. The 100-LQFP footprint supports compact fixture electronics, although a complete fixture still needs the ATA connector, drive power, USB routing, and accessory drive. Maximum USB high-speed signaling is 480 Mbit/s, but fixture throughput depends on the selected media. Production engineers should verify the exact MPN, validate hot-plug behavior if required, and protect the ATA bus from electrostatic discharge and ground-potential differences.
Embedded Portable Storage
The CY7C68320-100AXC can support a portable embedded-storage product that needs to exchange files with a USB-capable host. Its verified USB high-speed interface and dedicated ATA/ATAPI bridge role provide a focused solution for portable diagnostics, service tools, and compact data collectors. The 100-LQFP package is a surface-mount component and therefore supports repeatable automated assembly, unlike a connector-only passive adapter. Engineers should design the power path for both USB bus power and any separately powered storage device, because the ATA interface and USB controller have distinct current requirements that are not provided in the verified records. Enclosure grounding, ESD protection, cable shielding, and host compatibility are equally important for reliable field operation.
USB-to-ATA Storage Adapter
The CY7C68320-100AXC directly addresses a dedicated USB-to-ATA storage adapter, where its EZ-USB AT2LP bridging function provides the central conversion between a USB host and an ATA peripheral. According to the verified manufacturer-document index, the device supports USB 2.0 high-speed signaling at up to 480 Mbit/s and communicates with ATA or ATAPI storage devices. The 100-LQFP package is appropriate for a compact adapter PCB with surface-mount assembly. A production design must still implement connector routing, storage power control, ESD protection, and the required firmware image. Because the supplied data does not resolve every difference between CY7C68320-100AXC and CY7C68320C-100AXC, procurement and engineering teams should treat the exact ordering code as a controlled configuration item.

Tasarım Notları
Treat the 100-LQFP footprint as a controlled mechanical and electrical interface. The verified data confirms a 14 x 20 mm package but does not provide its pin table or exposed-pad details. Before routing, download the datasheet applying to the exact CY7C68320-100AXC order code and verify every USB, ATA, power, ground, clock, and configuration signal against the manufacturer pinout. Do not copy a layout or symbol solely from the CY7C68320C-100AXC listing because the supplied data does not prove identical pin assignments.
Plan the USB and ATA power paths independently rather than assuming either interface can source the other domain. The supplied records identify the controller as a 3.3 V-family USB interface device but do not provide complete current limits, voltage tolerances, load-switch requirements, or ATA power-sequence details. Confirm quiescent current, operating current, bus-powered current, and storage-media startup demand in the exact manufacturer datasheet. Include local bulk and bypass capacitance according to that document and verify brownout behavior during hot-plug or power-loss events.
Keep USB and ATA routing away from noisy power stages and maintain the return-current path referenced by each interface. USB high-speed edges can couple into adjacent ATA signals, while ATA cable or connector transitions can introduce reflections if terminations are incorrect. The verified records do not identify the required USB termination topology, ATA cable length, signal-rate limits, or impedance guidance, so those details must come from the exact datasheet and reference design. Use a solid ground plane, short high-speed connections, controlled escape routing, and connector ESD protection appropriate to the exposed environment.
The biggest procurement and design risk in the supplied records is confusion between CY7C68320-100AXC and CY7C68320C-100AXC. Both strings appear in distributor results, but the data does not establish that they are interchangeable. Distinguish the exact MPN on the purchase order, BOM, artwork, firmware release, and test documentation. Do not approve a substitute solely because it is also described as a 100-pin USB-to-ATA bridge; verify package drawing, pin-by-pin connectivity, electrical ratings, firmware compatibility, and lifecycle status first.
Uyumluluk Bilgisi
The supplied verified records do not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is marked not applicable because the product is not identified as an automotive-qualified device; this is not an automotive qualification claim. Compliance declarations must be confirmed from the exact manufacturer product page or declaration.
