CY7C68000-56PVXC USB 2.0 Transceiver | Infineon
N.º da peça: CY7C68000-56PVXC ✓ AtivoCY7C68000-56PVXC Visão geral
A USB transceiver is an interface IC that manages the physical-layer signaling between a USB host or controller and peripheral logic. The CY7C68000-56PVXC belongs to the broader hierarchy of interface ICs, USB interface controllers, USB-to-storage bridges, and semiconductors. Its USB 2.0 full-duplex architecture targets legacy storage peripherals that use the ATA parallel interface rather than modern native USB storage.
Key documented capabilities include full-duplex USB 2.0 operation, support for CompactFlash, support for one ATA or ATAPI device, board-level manufacturing test through USB, and ATA-bus high-impedance sharing with another controller such as IEEE 1394. The verified distributor record identifies the device as a 1/1 transceiver in a 56-SSOP package, while an inventory record reports 9,852 pieces available for immediate shipment.
Typical uses include legacy ATA and ATAPI storage adapters, CompactFlash readers, industrial data-acquisition equipment, embedded test systems, and legacy computer peripherals. The ATA interface can be electrically isolated, allowing the bus to be shared with another controller while the USB path remains the active communication link.
When designing a replacement board, engineers should verify the complete 56-SSOP footprint, exposed-pad requirements, USB differential-routing geometry, ATA signal integrity, crystal or clock implementation, and power rails against the manufacturer datasheet. The verified search results include a Cypress/Infineon datasheet listing with 14 pages and a 333 kbyte file, but no verified document number, revision, clock requirement, voltage values, or complete pin table was supplied.
This page consolidates distributor availability, the identified bridge features, and verified same-package cross-reference results. It also distinguishes the supported 56-SSOP variants from a separately listed LFXC package that cannot be treated as a footprint-compatible drop-in replacement.

Aplicações típicas
CY7C68000-56PVXC é adequado para 6 aplicaçãos: Legacy ATA Storage Adapter, CompactFlash Card Reader, Industrial USB-to-ATA Data Acquisition, USB Manufacturing and Production Test, ATA Bus Sharing Adapter, Legacy Computer Peripheral Upgrade.
Legacy ATA Storage Adapter
The CY7C68000-56PVXC fits a USB-to-ATA bridge because it combines a USB 2.0 full-duplex interface with support for one ATA or ATAPI device. Placing it between a USB host and a legacy parallel storage device avoids redesigning the storage connector and power path. Its ATA high-impedance capability is particularly useful when the parallel bus must remain available to another controller. The designer must still verify the ATA data and control timing, power rails, and termination against the full datasheet before release.
Recomendado
CompactFlash Card Reader
The documented CompactFlash support makes the CY7C68000-56PVXC applicable to a USB CompactFlash reader or removable-media adapter. Its USB interface provides the host-facing path while the bridge manages the legacy storage side of the design. The high-impedance ATA interface can also isolate the bus during card detection or when another controller temporarily owns it. Production designs should validate insertion, removal, power sequencing, and signal integrity under repeated connector cycling.
Recomendado
Industrial USB-to-ATA Data Acquisition
The CY7C68000-56PVXC is suitable for industrial adapters that bridge a modern USB host to a legacy ATA or ATAPI peripheral. Its full-duplex USB 2.0 interface supports bidirectional control and data transfer, while the ATA interface supports the older storage device. The ATA high-impedance function can permit controlled bus sharing with an additional controller. For industrial deployment, verify operating-temperature limits, transient protection, grounding, and sustained-load behavior, since those figures were not included in the supplied verified records.
Recomendado
USB Manufacturing and Production Test
The CY7C68000-56PVXC supports board-level manufacturing test through its USB interface, allowing production systems to exercise a populated board without a separate dedicated test fixture. A USB-connected test host can use this path for initialization checks and peripheral verification. The USB high-impedance ATA function is also useful during test because it can prevent the bridge from contending with another controller. Test software and production fixtures should still be validated against the manufacturer's documented test sequence.
Recomendado
ATA Bus Sharing Adapter
The CY7C68000-56PVXC can be used where an ATA bus must be shared between a USB path and another controller, with IEEE 1394 identified as one example in the verified feature description. Its high-impedance ATA interface allows the bridge to disengage electrically while USB remains active. This is useful in transitional systems where legacy storage must coexist with a newer transport. Firmware must manage ownership and contention correctly, and both controllers must use compatible voltage levels and signaling conventions.
Recomendado
Legacy Computer Peripheral Upgrade
The CY7C68000-56PVXC enables a modern USB host to retain access to an ATA or ATAPI peripheral that predates native USB storage. This makes it useful in retrocomputing, industrial refurbishment, and specialized data-recovery equipment. The bridge provides the protocol and physical interface while the host sees a USB device, avoiding replacement of the legacy drive connector. Deployment should account for boot-loader support, USB enumeration behavior, hot-plug requirements, and the limited 7.50 mm package width.

Principais diferenciais
- Direct USB-to-ATA/ATAPI bridge integration (vs General-purpose USB interface controllers)
- ATA interface can enter a high-impedance state (vs Bus controllers without a shared-bus isolation mode)
- Board-level test access through USB (vs Interfaces requiring separate production-test fixtures)
- CompactFlash and ATA support in one bridge (vs Single-media USB storage bridges)
Notas de projeto
Route the USB differential pair as a controlled-impedance pair with minimal length mismatch and continuous reference to a solid ground plane. Keep the USB connector, protection devices, and CY7C68000-56PVXC input path in the same physical region to minimize loop area and radiated emissions. Do not copy USB routing into the parallel ATA region; the ATA bus requires its own length, stub, and timing review.
Use the ATA high-impedance function only after confirming that the alternate controller can safely own the shared bus and that software will not enable both drivers simultaneously. Review the datasheet for required series termination, drive-strength settings, and bus turnaround timing. The verified data confirms high-impedance support but does not provide edge rates, propagation delays, or recommended termination values.
Separate analog-sensitive and digital switching paths in the power tree so USB activity does not inject noise into the ATA or attached storage-device rails. Place local bypass capacitors at the device supply pins and route return currents without sharing narrow neckdowns with USB and ATA return paths. Voltage ratings, capacitor values, and startup requirements were not included in the verified data and must be taken from the manufacturer datasheet.
Do not treat CY7C68000-56PVXCT as a functional alternative when building an approved-parts list; it is the tape-and-reel ordering form of the target device. Conversely, do not treat CY7C68000A-56LFXCT as a drop-in replacement because its LFXC package differs from the 56-SSOP footprint. Confirm the full order code, package drawing, pin assignments, and firmware compatibility before releasing a substitution.
The 56-SSOP package is only 7.50 mm wide, so connector placement and assembly access require careful planning. Check the manufacturer land pattern, solder-mask and paste recommendations, and whether any exposed thermal or structural pad is required. A footprint drawing was not present in the verified records, so the package drawing and pin table must be checked against the official 56-SSOP data.
Informações de conformidade
The supplied search excerpts reference RoHS and REACH comparison fields but do not state the compliance results for this exact order code. The device is an interface IC rather than an automotive-qualified power device, but no AEC-Q100 claim was provided. Compliance documentation must be obtained from the manufacturer or distributor for the exact CY7C68000-56PVXC order code.
