CY7C68001-56LFXC - USB 2.0 ATA Controller | Infineon
MPN: CY7C68001-56LFXC ✓ AktifCY7C68001-56LFXC Ringkasan
A USB interface controller is a semiconductor that manages the physical and protocol-level connection between a USB host and an external peripheral. This CY7C68001 belongs to the EZ-USB SX2 family of high-speed USB interface devices. Its position in the hierarchy is USB interface controller, then interface controller, then integrated circuit. It is used where a compact embedded system needs to expose legacy parallel ATA storage through a standard USB 2.0 connection.
The principal feature is support for one ATA/ATAPI device alongside CompactFlash. An 8-bit or 16-bit parallel datapath provides flexibility for different parallel-interface implementations. The 3.3 V operating supply and 56-QFN surface-mount package suit compact embedded equipment, while board-level manufacturing test through USB can simplify production workflows by allowing fixture equipment to communicate with the assembled board.
The ATA interface can be placed in a high-impedance state. This feature allows an ATA bus to be shared with another controller, such as an IEEE-1394 controller, which is useful in systems that must select between two paths to the same storage device. The interface choice reduces the need for a separate external bus switch when both controllers can place their ATA outputs in the inactive high-impedance state.
Typical uses include USB-to-ATA storage adapters, CompactFlash readers, embedded data acquisition systems, industrial storage interfaces, board-level production fixtures, and legacy ATA equipment connected to modern USB hosts. The device is particularly relevant when a design must preserve ATA/ATAPI support while adding a USB-facing controller and compact surface-mount footprint.
When laying out the PCB, verify the exposed-pad and thermal requirements directly against the manufacturer datasheet before production. The supplied web results confirm the 56-QFN 8 mm by 8 mm package but do not provide a complete pin map, operating-temperature range, absolute maximum ratings, or detailed electrical limits. Confirm those items and the complete schematic interface before releasing a board design or approving a second-source device.
This product record combines verified distributor pricing, package information, functional capabilities, source links, and a conservative drop-in assessment. The alternative list is intentionally limited because the supplied cross-reference evidence did not establish five distinct, fully documented pin-compatible replacements, preventing unsupported substitution claims.

Aplikasi Umum
CY7C68001-56LFXC cocok untuk 6 aplikasis: USB-to-ATA Storage Adapter, CompactFlash USB Reader, Legacy ATA Equipment Interface, Shared ATA Bus Controller, Board-Level Manufacturing Test, Embedded Data Acquisition Storage.
USB-to-ATA Storage Adapter
The CY7C68001-56LFXC fits a USB-to-ATA storage adapter because it combines a USB 2.0 host interface with support for one ATA/ATAPI device in a compact 56-QFN package. The controller's 8-bit or 16-bit parallel datapath accommodates the parallel-storage side of the bridge, while the 3.3 V supply aligns with compact embedded USB equipment. Its ATA interface can enter a high-impedance state, which is useful when the storage bus must be shared with another controller. The principal design check is pin-level verification against the selected ATA connector and the manufacturer land pattern; the available sources do not establish every timing, current, or thermal limit.

CompactFlash USB Reader
The CY7C68001-56LFXC is appropriate for a CompactFlash reader that exposes removable storage through a USB 2.0 host. Verified product information specifically identifies CompactFlash support alongside one ATA/ATAPI device, allowing one controller design to cover both storage interfaces without changing the USB-facing architecture. Its 56-QFN 8 mm by 8 mm package helps reduce board area, and the 3.3 V operating supply is suitable for compact embedded products. Designers should confirm signal levels, timing, exposed-pad handling, and protection requirements directly in the manufacturer datasheet before laying out a production reader.

Legacy ATA Equipment Interface
The CY7C68001-56LFXC can modernize legacy ATA/ATAPI equipment by placing the EZ-USB SX2 USB 2.0 controller between a modern host and an existing parallel storage interface. Verified support for one ATA/ATAPI device provides a defined bridge function, while the selectable 8-bit or 16-bit datapath supports implementation flexibility. This use case is especially useful when replacing an obsolete host interface without redesigning the ATA side of the equipment. Because the supplied records do not list absolute maximum ratings, timing margins, or the complete pin map, the legacy interface must be qualified against the latest manufacturer datasheet.

Shared ATA Bus Controller
The CY7C68001-56LFXC fits a shared ATA-bus design because its ATA interface can be placed in a high-impedance state. According to the verified EZ-USB AT2LP bridge description, this allows the ATA bus to be shared with another controller such as an IEEE-1394 controller, avoiding contention when the second controller is inactive. The USB 2.0 interface remains the primary connection to a host in the selected operating mode. Board-level implementation must carefully coordinate enable, ownership, and high-impedance behavior; the supplied web data does not provide the corresponding timing or pin-state table.

Board-Level Manufacturing Test
The CY7C68001-56LFXC supports board-level manufacturing testing through its USB interface, reducing the need for a separate production-test interface on assembled boards. The controller can expose the ATA-connected circuitry to a USB-based fixture, which is useful in automated test systems and compact production adapters. Its 56-QFN 8 mm by 8 mm package and 3.3 V operating supply align with embedded test hardware. The manufacturing test procedure should be implemented only after confirming the supported commands, test-mode entry conditions, and board power requirements in the current manufacturer documentation.

Embedded Data Acquisition Storage
The CY7C68001-56LFXC can serve as the storage-facing USB interface in an embedded data-acquisition system that records to ATA/ATAPI or CompactFlash media. USB 2.0 provides the connection to a host computer, while the controller manages access to one supported ATA/ATAPI device. The 8-bit or 16-bit datapath and compact 56-QFN package make the device suitable for space-constrained instrumentation, provided the system does not exceed the controller's verified electrical and timing limits. Engineers should also account for ATA connector requirements, inrush behavior, and the thermal design of the exposed-pad land pattern.

Catatan Desain
Use the manufacturer's 56-QFN land pattern and exposed-pad layout for the CY7C68001-56LFXC. The supplied sources confirm a 56-QFN 8 mm by 8 mm package but do not provide the exact pad dimensions, pin numbering, or exposed-pad connection instructions. Download the current manufacturer package drawing before PCB release and verify that the via pattern satisfies its soldering and thermal requirements.
Route the USB and parallel ATA/ATAPI interfaces according to the manufacturer reference layout rather than inferring connectivity from the controller family. USB differential pairs require controlled geometry and reference-plane continuity, while ATA signals should be kept away from switching nodes where practical. Since the supplied evidence contains no complete pin map or trace-length requirements, these constraints must be taken from the datasheet and interface guidelines.
Do not approve a suffix or related-family substitution solely because both devices use a 56-QFN footprint. CY7C68001-56LTXC and CY7C68001-56LFC have the same package naming pattern, while the comparison with CY7C68015A-56LFXC explicitly identifies possible voltage-range and power-consumption differences. Confirm pin names, supply limits, timing, exposed-pad requirements, temperature grade, and qualification before calling any alternative a production drop-in.
Design the 3.3 V supply path with local decoupling and verify the capacitor values and effective capacitance against the manufacturer datasheet. The supplied records do not include input-voltage limits, quiescent current, or transient requirements, so values must not be inferred from the nominal 3.3 V description. Account for USB bus-powered and self-powered implementations separately because their source current and inrush behavior differ.
Informasi Konformitas
The supplied sources do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is marked not applicable because this is a general-purpose USB interface controller rather than an automotive-qualified device in the provided data.
