CY7C68300A-56PVC - USB 2.0 to ATA Bridge | Infineon
Référence : CY7C68300A-56PVC ✓ ActifCY7C68300A-56PVC Présentation
A USB-to-ATA bridge is an interface controller that translates USB traffic into ATA commands and data transfers. Within the product hierarchy, it is a USB interface bridge, then a storage interface controller, then an integrated circuit and semiconductor. This device is particularly relevant to legacy embedded platforms, industrial equipment, and storage peripherals designed around the ATA/ATAPI command set before USB mass-storage became dominant.
The available specifications identify USB 2.0 on the host side, ATA and ATAPI support on the storage side, a 3.3 V supply, and a 56-pin SSOP package. The operating-temperature range reported by the distributor data is 0°C to 70°C, placing the specified device in a commercial-temperature environment. These characteristics make the controller suitable for USB-to-ATA adapters, embedded storage subsystems, and equipment requiring compatibility with existing ATA/ATAPI storage peripherals.
The controller is intended to absorb protocol conversion between the USB host domain and the parallel ATA device domain. This separation allows a USB-capable processor or embedded host to manage removable or fixed ATA storage without implementing the ATA electrical interface directly. System designers must still validate command support, media compatibility, power sequencing, and cable or connector behavior in the final equipment.
Typical implementations include USB storage adapters, embedded data-acquisition systems, industrial control equipment, and legacy computing platforms being extended with USB connectivity. The 56-SSOP package offers a high pin count for external interface, power, control, and data connections, but it requires careful high-density PCB layout and appropriate connector signal-integrity practices.
A primary design consideration is that USB and ATA are both sensitive to voltage, timing, and signal-integrity requirements. Validate input and output capacitance, cable behavior, pull-up and pull-down networks, supply sequencing, ground return paths, and enclosure or shield termination against the manufacturer datasheet before production. This page consolidates the verified distributor data, strict drop-in candidates, comparison parameters, and application guidance into an engineering-focused purchasing reference.

Applications typiques
CY7C68300A-56PVC convient pour 6 applications: Legacy USB-to-ATA Storage Adapter, Embedded Industrial Data Acquisition, USB-Enabled Legacy Controller, ATA Storage Test and Service Fixture, Instrumentation Data Archive, Retrofitted Computer Storage Expansion.
Legacy USB-to-ATA Storage Adapter
The CY7C68300A-56PVC fits a USB-to-ATA adapter because it provides a USB 2.0 host-facing interface and an ATA/ATAPI device-facing controller in one 56-SSOP package. The bridge can translate commands between a USB-capable host and conventional ATA storage instead of requiring the host processor to implement parallel ATA signaling directly. Its specified 3.3 V supply simplifies integration with modern embedded systems, while the 56-pin package provides the external interface and control connections needed by the bridge. During design, verify the USB connector, device detection, media enumeration, transfer-rate limits, and power-removal behavior with the manufacturer datasheet. The supplied sources do not provide maximum transfer rates or complete electrical limits, so those constraints must be confirmed before selecting enclosure, cable, or ATA-device combinations.
Recommandé
Embedded Industrial Data Acquisition
The CY7C68300A-56PVC is appropriate for industrial data-acquisition equipment that retains ATA or ATAPI storage for logs, calibration records, or buffered measurement data. Its USB 2.0 interface can connect the equipment to a host computer, while the ATA/ATAPI side accommodates established storage hardware and existing mechanical layouts. The reported 0°C to 70°C operating range suits many controlled industrial environments without an extended-temperature claim. Engineers should plan for industrial qualification at the equipment level, including vibration, power interruption, brownout recovery, grounding, and enclosure temperature. Because the verified data does not specify ATA transfer rate, USB signaling details, or ATA power sequencing, these points require confirmation from the manufacturer datasheet and testing with the intended media.
Recommandé
USB-Enabled Legacy Controller
The CY7C68300A-56PVC can add USB connectivity to a legacy embedded controller that already relies on ATA or ATAPI storage. Placing the bridge between the USB host and the storage device isolates the original controller from direct USB protocol handling and allows a USB-capable computer or service terminal to access the storage subsystem. The 3.3 V operating supply and surface-mount 56-SSOP package support integration into a modern control board. Firmware must support the bridge's USB enumeration and storage-access workflow, while the original platform must continue presenting the expected ATA device behavior. Prototype validation should cover hot-plug behavior, media-change notification, suspend and resume, unexpected disconnect, filesystem compatibility, and data integrity after power cycling.
Recommandé
ATA Storage Test and Service Fixture
The CY7C68300A-56PVC can serve as the storage bridge in a test fixture for exercising legacy ATA or ATAPI equipment through USB. The USB 2.0 side provides a convenient connection to a laptop or automated test system, while the controller handles the ATA-facing side of the storage subsystem. This arrangement can reduce the need for a full legacy motherboard when the objective is media enumeration, read or write verification, firmware update, or service diagnostics. A useful fixture should include deterministic power controls, cable strain relief, accessible storage connectors, and status indication for enumeration and I/O faults. Validate whether the bridge supports the exact ATA modes, command sets, and media types used by the legacy system. The available distributor information confirms the ATA/ATAPI function but does not provide a complete command-support matrix.
Recommandé
Instrumentation Data Archive
The CY7C68300A-56PVC is suitable for instrumentation systems that need to move measurement archives from ATA-based storage to a USB-connected workstation. A USB 2.0 host link can provide a convenient path for transferring files, while ATA/ATAPI compatibility allows use of established storage media and existing storage conventions. The controller's 3.3 V supply and 56-SSOP surface-mount package suit compact instrument designs, although high-density PCB layout requires controlled escape routing for USB and ATA signals. Engineering validation should address ground bounce, connector insertion events, simultaneous USB and ATA activity, file-system compatibility, and retention of metadata after interrupted transfers. Because transfer-rate and electrical-characteristic data are absent from the supplied sources, determine the achievable throughput from the manufacturer datasheet rather than relying on the USB 2.0 label alone.
Recommandé
Retrofitted Computer Storage Expansion
The CY7C68300A-56PVC can support retrofits that add USB storage access to an older computer or control system using ATA/ATAPI peripherals. The controller provides a defined bridge between the modern USB host and the legacy parallel storage bus, avoiding a full motherboard redesign when only a new host connection is needed. The nominal 3.3 V supply allows integration with current embedded logic, and the 56-SSOP package supports compact board construction. System-level verification is essential because ATA cable length, connector keying, media power, termination, and USB host behavior can constrain reliability. Use shielded or short interconnect arrangements where appropriate, provide solid ground references, and test every intended ATA device under repeated insertion and removal. The reported 0°C to 70°C range applies to the controller specification, not necessarily to the complete retrofit assembly.

Notes de conception
Treat the USB and ATA interfaces as separate high-speed or high-fanout signal groups. Confirm the manufacturer-specified trace lengths, impedance targets, series terminations, and connector topology before routing. Keep the 56-SSOP footprint on a continuous ground plane, minimize stub branches, and place required support components close to their associated pins. The supplied data does not include a complete pinout, so no individual power or signal assignment should be inferred from the package drawing.
Design a 3.3 V supply path that accommodates the final USB and ATA load rather than the nominal interface label alone. Because input current, USB output current, ATA output current, and power dissipation are not specified in the supplied sources, obtain the manufacturer limits before setting regulator capacity or copper area. Include local bulk and high-frequency bypassing according to the reference circuit, and verify startup, suspend, resume, and storage-media power-state transitions with the complete assembly.
Do not treat an EZ-USB AT2-family ordering code as a guaranteed drop-in replacement. The supplied cross-reference comparison warns that main parameters and circuit structures can differ even when functional characteristics appear similar. For any candidate in the alternatives list, verify the numbered pinout, USB descriptors, ATA command support, timing, clock requirements, supply sequencing, package dimensions, and firmware dependencies. Also confirm the manufacturer's lifecycle and availability status before committing to production.
Informations de conformité
The supplied distributor snippets do not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is treated as not applicable because this is an industrial interface controller rather than an automotive-qualified device; no automotive qualification claim is made.
