A USB interface controller is an interface IC that bridges a conventional parallel processor bus with a serial USB link. It belongs to the USB controller hierarchy, where USB 2.0 support is added to an embedded system without requiring the host processor to implement the complete USB physical and protocol layer. The CY7C68001 series is identified as the EZ-USB SX2 high-speed USB interface device and also appears in documentation for EZ-USB AT2LP USB 2.0-to-ATA/ATAPI bridges.
Verified catalog information identifies an 8/16-bit datapath, a 24 MHz operating frequency, USB 2.0 connectivity, and a 56-pin SSOP package. The associated documentation also describes support for CompactFlash and one ATA or ATAPI device, board-level manufacturing test through the USB interface, and a high-impedance ATA interface state that permits sharing the ATA bus with another controller such as an IEEE-1394 controller.
The parallel datapath lets an external processor exchange USB data through a conventional parallel interface while the dedicated USB controller handles the USB 2.0 high-speed endpoint behavior. This architecture is useful when a product already contains a capable application processor but needs a specialized, standards-oriented USB interface. The 56-pin SSOP package also provides a larger pin count than many compact USB transceivers, supporting the parallel-side connections and dedicated control signals required by this bridge-oriented device family.
Typical uses include USB-to-ATA storage adapters, CompactFlash readers, board-level production and manufacturing test systems, and legacy peripheral designs being upgraded with USB 2.0 connectivity. The ATA/ATAPI description and CompactFlash support make the controller especially relevant to storage-interface bridges rather than general-purpose low-speed USB transceivers.
Designers should verify the exact pin functions, clock requirements, timing limits, power rails, ATA interface states, and external component requirements against the manufacturer datasheet before layout. The verified excerpts do not provide complete electrical tables or a complete pin list, so those details should not be inferred from the catalog summary. The SSOP package also requires careful plane assignment and signal-integrity review around the high-speed USB differential pair.
This page consolidates verified distributor catalog information, package identification, USB function details, candidate drop-in comparisons, and practical design cautions. It distinguishes documented facts from unverified specifications and avoids presenting unsupported timing, pricing, compliance, or pin-assignment data as established engineering parameters.

Типичное применение
CY7C68001-56PVXC подходит для 6 применениеs: USB-to-ATA Storage Adapter, CompactFlash Reader, Board-Level Manufacturing Test, Shared ATA Bus Expansion, FPGA-Based USB Peripheral, Legacy ATA Peripheral Upgrade.
USB-to-ATA Storage Adapter
The CY7C68001-56PVXC fits a USB-to-ATA storage adapter because the verified documentation identifies EZ-USB SX2 USB 2.0 operation, support for one ATA or ATAPI device, and an 8/16-bit parallel datapath. It can sit between an external storage controller or processor and a USB-facing system, reducing the protocol burden on the application processor. The 24 MHz operating frequency and 56-pin SSOP package provide a defined implementation platform, although the supplied data does not specify ATA transfer rates or timing limits. Designers should confirm the exact electrical pin mapping, power requirements, USB descriptors, and firmware support before release.
Рекомендуется
CompactFlash Reader
The CY7C68001-56PVXC is suitable for a CompactFlash reader because the verified feature description explicitly includes CompactFlash support alongside USB 2.0 high-speed operation. The controller's 8/16-bit parallel datapath allows an external processor, DSP, ASIC, or FPGA to supervise data handling while the EZ-USB SX2 device handles the USB-facing function. The 56-pin SSOP package offers dedicated connections for a bridge-oriented design rather than a minimal USB transceiver footprint. Before schematic capture, verify the required CompactFlash signal set, card-detection behavior, power levels, and protocol implementation in the manufacturer documentation.
Рекомендуется
Board-Level Manufacturing Test
The CY7C68001-56PVXC can support board-level manufacturing test through its USB interface, as stated explicitly in the verified documentation. This application is valuable when production equipment must exercise USB-connected circuitry without adding a separate test controller to every board. The EZ-USB SX2 interface provides USB 2.0 high-speed connectivity while the parallel datapath gives an external master access to board functions. Because the verified excerpts do not state the available endpoints, test command structure, or power-up timing, the test fixture and host software must be validated against the complete manufacturer documentation and reference procedures.
Рекомендуется
Shared ATA Bus Expansion
The CY7C68001-56PVXC is a candidate for systems that need to share an ATA bus with another controller. The verified feature set states that the ATA interface can be placed in a high-impedance state, allowing another controller, including an IEEE-1394 controller, to access the bus. This makes the device relevant to multi-host or adapter designs where deterministic bus ownership is required. The 56-pin SSOP package provides the necessary interface connections, but the supplied material does not specify arbitration timing, enable polarity, or contention rules. Pin-level and timing verification is essential before implementing shared-bus operation.
Рекомендуется
FPGA-Based USB Peripheral
The CY7C68001-56PVXC is appropriate for an FPGA-based USB peripheral when the FPGA does not implement the complete USB 2.0 interface directly. The controller's EZ-USB SX2 architecture works with external masters including FPGAs, while its 8/16-bit parallel datapath provides a selectable path for transferring data into FPGA logic. The documented 24 MHz operating frequency gives the design a clear clock reference, and the 56-pin SSOP package supplies more interface connectivity than a basic four-pin transceiver. Engineers must still define the parallel bus timing, control signals, clocking scheme, and FPGA endpoint logic against verified electrical specifications.
Рекомендуется
Legacy ATA Peripheral Upgrade
The CY7C68001-56PVXC can be used to add USB 2.0 connectivity to an existing ATA or ATAPI peripheral. Its dedicated EZ-USB SX2 controller handles the USB-facing portion of the design, while the external microprocessor or DSP manages device-specific behavior and the parallel datapath transfer. This separation can simplify an upgrade of legacy storage equipment without requiring the original controller to implement a full USB stack. The verified excerpts confirm USB 2.0, one ATA or ATAPI device, and CompactFlash support, but they do not provide complete timing or electrical limits. Backward compatibility should therefore be tested at the command, signal, and system levels.

Заметки по проектированию
Route the USB high-speed differential pair as a short, continuous, impedance-controlled pair and keep the 24 MHz clock away from sensitive parallel and ATA signals. The verified material does not provide a trace impedance or layout stackup, so obtain the manufacturer reference layout and impedance specification before fabrication. Confirm that the 56-pin SSOP footprint, exposed pad status, and ground-return arrangement match the selected ordering code.
Decouple the device with the power network specified by the manufacturer datasheet; capacitor values, voltage rails, and sequencing requirements were not included in the verified excerpts and must not be guessed. Provide a low-impedance return path for the clock, parallel datapath, and ATA signals, especially when the package interfaces with a high-speed processor or FPGA. Validate supply tolerance and startup behavior across the required USB enumeration and ATA command sequence.
Do not treat a shared 56-pin SSOP package as proof that an alternative is electrically interchangeable. Compare USB descriptors and endpoints, parallel-datapath width, clock polarity, ATA signal states, high-impedance control, electrical timing, and power requirements against both manufacturer datasheets. The supplied comparison excerpts identify related parts but do not contain enough detail to approve a drop-in substitution without schematic and firmware review.
Exercise the design with the intended external master, including worst-case parallel-bus loading, clock jitter, USB cable, ATA cable, and CompactFlash card behavior. The documented 8/16-bit datapath and 24 MHz operating frequency establish the architectural basis, but the supplied material omits setup time, hold time, propagation delay, and I/O timing. Use measured eye diagrams or vendor qualification procedures to verify margin in the assembled system.
Информация о соответствии
The supplied excerpts include cross-reference pages mentioning RoHS and REACH as compared attributes but do not provide an explicit compliance value for this MPN. The operating-temperature listing of 0 °C to +70 °C indicates a commercial-temperature catalog entry, but no AEC-Q100 qualification statement is present.
