CY7C68310-80AXC Présentation

The Infineon Technologies CY7C68310-80AXC is a low-power USB 2.0 to ATA/ATAPI bridge integrated circuit with a 2.5 V operating supply identified in the verified results and an 80-pin TQFP package. It is designed to provide a bridge between a USB 2.0 host interface and ATA or ATAPI storage devices, making it suitable for embedded storage adapters, legacy computer peripherals, and systems that need protocol conversion without implementing the complete storage interface in host hardware. The verified sources identify the part as an ISD-300LP Low-Power USB 2.0 to ATA/ATAPI Bridge IC.

A USB-to-ATA bridge is an interface controller that translates USB commands and data traffic into ATA/ATAPI commands and electrical signaling. In the device hierarchy, it belongs to interface ICs, then data converters and bus bridges, and finally the broader semiconductor category. The bridge can help preserve investment in storage mechanisms designed around parallel ATA while adding a USB connection for a newer host system. Its low-power designation is important for portable and embedded equipment where USB connectivity must not dominate the system power budget.

The available verified data confirms the key identity and package information: CY7C68310-80AXC, USB 2.0, ATA/ATAPI bridge operation, 2.5 V supply information, and an 80-pin TQFP package measuring 12 x 12 mm according to the DigiKey result. The search results also identify the device as an Infineon/Cypress component through distributor and Octopart listings. Detailed electrical limits, transfer-rate values, operating-temperature limits, and timing parameters were not supplied in the verified snippets, so those values must be confirmed from the manufacturer datasheet before a design is released.

Typical uses include USB storage adapters, embedded data loggers, industrial equipment with legacy ATA storage, test fixtures, and computer systems that need a controlled bridge to an ATA device. In these applications, the bridge handles USB enumeration and storage-protocol translation while the host operating system presents the storage device through its normal USB mass-storage path. Designers should confirm host compatibility, device-side ATA signaling, power requirements, connector implementation, and operating-system support using the official CY7C68310 documentation.

The most important design consideration is interface validation rather than raw substitution. A candidate part must match the 80-pin TQFP footprint, pin functions, supply requirements, USB behavior, ATA/ATAPI timing, and operating system requirements. The verified web results do not establish a qualified pin-to-pin replacement, so substitute parts should not be treated as drop-in without manufacturer documentation. This page distinguishes verified facts from missing technical data and emphasizes datasheet-based review.

This product page combines the verified distributor identity, package information, pricing reference, and practical selection context with explicit markers for unavailable electrical specifications. It is intended as an engineering-oriented starting point for sourcing and design review rather than a substitute for the full manufacturer datasheet.

Applications typiques

CY7C68310-80AXC convient pour 6 applications: USB Storage Adapter, Embedded Data Logger, Legacy Computer Peripheral, Industrial Storage Interface, Test and Measurement Fixture, USB-to-ATA Development Platform.

💾

USB Storage Adapter

CY7C68310-80AXC fits a USB storage adapter that lets a USB host communicate with an ATA or ATAPI device. Its verified USB 2.0 and ATA/ATAPI positioning matches the required protocol bridge, while the 80-pin TQFP package supports a dedicated surface-mount layout. The adapter designer must still validate USB enumeration, device compatibility, power, connector routing, and host mass-storage support. The principal benefit is reuse of an established ATA storage architecture behind a USB connection rather than redesigning the storage bus into the host controller.

🖥️

Embedded Data Logger

The bridge can be considered for an embedded data logger that records to an ATA-based storage medium while exposing a USB service connection to a host computer. USB 2.0 provides the host-side transport identified in the verified data, and the ATA/ATAPI side provides the storage-device path. The 80-pin TQFP footprint leaves a substantial routing requirement, so the PCB must follow the official pinout and reference design. Validate write timing, power-loss behavior, thermal conditions, and operating-system compatibility before production.

💻

Legacy Computer Peripheral

CY7C68310-80AXC is relevant when a legacy computer peripheral needs to preserve an ATA storage interface while adding USB connectivity. The verified source identifies the part as a USB 2.0 to ATA/ATAPI bridge in an 80-pin TQFP, which is suitable for a dedicated interface card rather than a minimal breadboard experiment. Integration requires careful validation of voltage levels, signal timing, connector standards, and operating-system drivers. The design benefit is protocol reuse, while the tradeoff is a relatively complex bridge footprint and dependence on the exact device implementation.

🏭

Industrial Storage Interface

The bridge may be used in an industrial storage interface when an ATA-based device must be connected to a USB-capable controller or service port. Its low-power identification is useful for embedded equipment, but the supplied data does not provide industrial temperature limits, isolation ratings, or EMC test results. Engineers should therefore treat the device as a board-level protocol bridge rather than assume industrial ruggedness. Validate environmental limits, grounding, cable length, transient protection, and enclosure heat dissipation using the manufacturer documentation.

🔧

Test and Measurement Fixture

A test fixture can use CY7C68310-80AXC when a fixture must access an ATA or ATAPI device through USB for manufacturing, programming, or diagnostic operations. The USB 2.0 host interface simplifies connection to a test computer, while the bridge preserves the target storage protocol. The 80-pin TQFP package requires careful breakout or fixture routing, and the design must account for signal integrity, supply sequencing, device power, and insertion tolerance. Because no transfer-rate or timing figures were supplied, bench validation should precede high-volume fixture release.

🧩

USB-to-ATA Development Platform

CY7C68310-80AXC can serve as the bridge element in a development platform for prototyping USB-to-ATA storage behavior. The verified 2.5 V identity and 80-pin TQFP package make it suitable for a controlled prototype only after the complete supply and pin requirements are confirmed. Development boards should provide accessible USB, ATA connectors, test points, decoupling, and configurable power rails. Avoid copying generic schematics from unrelated USB controllers; use the official CY7C68310 reference information to ensure signal mapping and protocol behavior are correct.

What is the CY7C68310-80AXC?
The CY7C68310-80AXC is a low-power USB 2.0 to ATA/ATAPI bridge IC. According to the verified distributor and datasheet-index results, it belongs to the ISD-300LP family and is packaged in an 80-pin TQFP. The IC is intended to translate between a USB host connection and an ATA or ATAPI storage interface, which is useful when a system needs USB connectivity for an ATA-based storage device.
What package does CY7C68310-80AXC use?
The CY7C68310-80AXC uses an 80-pin TQFP package measuring 12 x 12 mm, as stated in the verified DigiKey result. The package is a surface-mount TQFP with 80 leads. Before PCB release, engineers should obtain the official manufacturer pinout and land pattern because the supplied verified results do not include the complete pin numbering, exposed-pad details, or package drawing.
Where can I find the CY7C68310 datasheet PDF?
The CY7C68310 datasheet PDF can be accessed through the verified datasheet-index result at https://www.alldatasheet.com/datasheet-pdf/pdf/84495/CYPRESS/CY7C68310.html. The search results identify it as the ISD-300LP Low-Power USB 2.0 to ATA/ATAPI Bridge IC datasheet. Download the current manufacturer document when possible and verify revision and document status against the Infineon or Cypress source.
Is CY7C68310-80AXC a USB 2.0 part?
Yes. The verified distributor and datasheet-index results explicitly describe CY7C68310-80AXC as a USB 2.0 to ATA/ATAPI bridge. The USB 2.0 designation identifies the host-side interface, while the ATA/ATAPI side provides storage-device connectivity. Actual transfer performance depends on the complete system design, attached storage device, cable, host controller, and operating-system support.
What is the supply voltage of CY7C68310-80AXC?
The verified FindIC result identifies the CY7C68310-80AXC as a 2.5 V device. That value should be treated as a verified search-result identity detail, not a complete power specification. The input-voltage tolerance, core and I/O voltage requirements, sequencing, current consumption, and regulator requirements must be confirmed in the manufacturer datasheet before schematic release.
What can replace CY7C68310-80AXC?
No verified drop-in replacement for CY7C68310-80AXC was identified in the supplied cross-reference results. A valid replacement would need the same 80-pin TQFP footprint, pin-to-pin mapping, USB 2.0 behavior, ATA/ATAPI support, electrical limits, timing, and firmware or host compatibility. Do not install a similar USB storage controller solely because it has the same package; verify the official datasheet and qualification first.
Is CY7C68310-80AXC in stock?
The verified LCSC result states that CY7C68310-80AXC is in stock and lists a starting price of $2.1494. The result does not state the quantity available, regional inventory, lead time, or whether stock remains available at the time of purchase. Confirm current stock and delivery terms directly with the distributor, and treat the listed price as a reference as of 2026-10-23.
What is the price of CY7C68310-80AXC?
The verified LCSC result lists CY7C68310-80AXC from $2.1494. This is a distributor reference price, not a guaranteed XAIPART quote, and the supplied data does not provide volume pricing. Pricing as of 2026-10-23 should be confirmed at the point of order because distributor pricing, currency, inventory, and quantity breaks can change.
What is the lead time for CY7C68310-80AXC?
The supplied verified data does not state a guaranteed lead time for CY7C68310-80AXC. The LCSC listing indicates that the part is in stock, but it does not provide a dated lead-time commitment. Request a written quotation and delivery estimate for your exact quantity, shipping destination, and packaging configuration.
Is CY7C68310-80AXC suitable for a USB storage adapter?
The CY7C68310-80AXC is functionally suited to a USB storage adapter that connects a USB host to an ATA or ATAPI storage device.

Confirm signal integrity, power supply design, device support, connector requirements, and operating-system behavior in the complete design.
What is the pinout of CY7C68310-80AXC?
The complete CY7C68310-80AXC pinout is not included in the supplied verified web snippets. The verified results confirm an 80-pin TQFP package, but they do not provide the 80 numbered pin names or descriptions. Use the official CY7C68310 datasheet pinout and package drawing for PCB layout; the pinout is therefore not reproduced here to avoid inventing pin assignments.
How does CY7C68310-80AXC compare with a generic USB-to-ATA bridge?
CY7C68310-80AXC is a specific 80-pin TQFP USB 2.0 to ATA/ATAPI bridge in the ISD-300LP family, whereas a generic USB-to-ATA bridge may use a different package, interface generation, or command set. A meaningful comparison requires verified USB speed, ATA timing, pin mapping, power requirements, and host compatibility. Those alternative specifications were not provided, so no numerical drop-in comparison can be made.
When should I choose CY7C68310-80AXC?
Choose CY7C68310-80AXC when a design specifically requires a USB 2.0 to ATA/ATAPI bridge and can accommodate an 80-pin TQFP layout. The part is especially relevant to embedded storage adapters and systems retaining ATA storage. It is not a universal USB-to-storage substitute; verify electrical limits, pinout, device support, power, and lifecycle availability before committing to it.
What are the key specifications engineers should know about CY7C68310-80AXC?
The verified identity points are USB 2.0 connectivity, ATA/ATAPI bridging, a 2.5 V supply reference, and an 80-pin TQFP package measuring 12 x 12 mm. The device is also identified as a low-power ISD-300LP bridge. Transfer rate, operating temperature, current consumption, logic levels, timing, and lifecycle status were not supplied in the verified data and must be taken from the manufacturer datasheet.
Does CY7C68310-80AXC require special PCB layout?
Yes, the device requires a layout based on its official 80-pin TQFP datasheet and reference circuitry. USB and ATA signals are high-speed or timing-sensitive interfaces, so trace routing, return paths, decoupling, grounding, connector placement, and impedance control must follow the manufacturer recommendations. Because the supplied snippets do not include layout values or pin definitions, those details cannot be specified reliably from the provided data.

Guide de sélection

Choose CY7C68310-80AXC when the design specifically needs a USB 2.0 host connection to an ATA or ATAPI storage device and the PCB can accommodate an 80-pin TQFP. Its verified package and protocol identity make it a strong candidate for embedded storage adapters, legacy peripherals, data loggers, and test fixtures. Do not select it as a generic USB-to-SATA or USB-to-NVMe controller; the storage-side protocol must match. No verified drop-in alternatives were identified, so replacement should be based on manufacturer documentation rather than package similarity. Confirm the complete pinout, electrical limits, operating temperature, lifecycle status, storage-device support, and host compatibility before committing to production.

Principaux différenciateurs

  • Specific USB 2.0 to ATA/ATAPI bridge function (vs Generic USB-to-storage bridge)
  • Dedicated 80-pin TQFP integration (vs Small-package USB storage controller)
  • Low-power ISD-300LP positioning (vs Higher-power storage bridge)

Notes de conception

Start the layout from the official CY7C68310 80-pin TQFP pinout and package drawing rather than from a generic USB controller footprint. Keep USB and ATA routing away from noisy power-converter regions, provide continuous return paths, and place required decoupling at the device pins. Because the supplied verified data does not include pin definitions or reference-layout values, exact trace widths, spacing, and component placements must come from the manufacturer documentation.

Validate the complete power tree before schematic release. The verified search result identifies a 2.5 V reference, but it does not specify the input range, internal rails, I/O levels, sequencing, or current limits. Confirm every rail required by USB, ATA, and the attached storage device, then include local bulk and high-frequency decoupling with placement verified against the datasheet. Do not infer the USB connector or ATA-device power requirements from the bridge supply alone.

Treat USB and ATA connections as interface signals whose routing quality affects enumeration, command transfer, and data integrity. Keep connector and protection-device paths short, maintain return-path continuity, avoid unnecessary stubs, and use controlled-impedance routing where the implementation requires it. The verified snippets do not provide rise-time, impedance, timing, or maximum-cable values, so signal-integrity targets must be established from the official electrical tables and the selected storage device.
