CY7C68310-80AXC 概要
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.

主な用途
CY7C68310-80AXC の用途: 6 件s: 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.
おすすめ
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.
おすすめ
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.
おすすめ
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.
おすすめ
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.
おすすめ
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.

選定ガイド
主な差別化要因
- 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)
設計ノート
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.
コンプライアンス情報
The supplied verified results do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Obtain current compliance declarations from Infineon/Cypress or the authorized distributor.
