CY7C68320C-100AXA - USB 2.0 ATA Bridge | Infineon
MPN: CY7C68320C-100AXA ✓ सक्रियCY7C68320C-100AXA अवलोकन
A USB-to-ATA bridge is a specialized interface IC that translates USB transactions into ATA and ATAPI commands. This capability allows legacy parallel storage equipment to operate through a USB connection without redesigning the storage subsystem. The device therefore belongs to the hierarchy of USB interface controllers, peripheral interface ICs, interface adapters, and general-purpose semiconductors used in data-transfer and storage applications.
The CY7C68320C-100AXA operates from a 3.3 V supply and supports full-speed and high-speed USB 2.0 operation. Its ATA/ATAPI side provides the command and data interface expected by compatible storage devices, while the USB side manages enumeration and data transfer with a USB host. The 100-pin TQFP package offers ample routing capacity for signal, control, power, and interface functions in systems that require a dedicated USB storage interface rather than a simpler general-purpose USB-to-serial converter.
Typical uses include USB-connected external storage, industrial data acquisition systems, kiosk peripherals, legacy equipment modernization, and embedded systems that need to expose an ATA device through USB. The controller can also be considered for service and recovery equipment intended to read, initialize, or diagnose ATA-compatible media. Implementation requires careful USB signal routing, controlled 3.3 V power delivery, and firmware or operating-system support for the selected USB mass-storage behavior.
Designers should verify the complete pin assignment, supported ATA device modes, USB enumeration behavior, and required external components against the manufacturer datasheet before layout release. USB differential pairs should be routed as controlled-impedance, length-matched traces, while the ATA and ATAPI signals require adequate grounding and short return paths. Power sequencing and signal-integrity margins are especially important when the bridge is placed between a host connector and external storage media.

सामान्य अनुप्रयोग
CY7C68320C-100AXA के लिए उपयुक्त है 6 अनुप्रयोगs: USB-Connected External Storage, Industrial Data Acquisition, Kiosk and Self-Service Peripherals, Legacy Equipment Modernization, ATA Media Diagnostics and Recovery, Embedded USB Storage Gateway.
USB-Connected External Storage
The CY7C68320C-100AXA fits legacy external-storage products that expose an ATA-compatible device through a USB 2.0 host connection. Its full-speed and high-speed USB 2.0 support provides the required host-side transfer path, while the ATA/ATAPI interface handles commands and data on the storage side. The 3.3 V supply and 100-TQFP package make it suitable for a dedicated bridge section in an enclosure, dock, or service appliance. Implementation must confirm media compatibility, descriptors, enumeration behavior, and host-driver expectations before production.
Industrial Data Acquisition
Industrial acquisition equipment can use the CY7C68320C-100AXA when legacy ATA equipment must communicate with a modern USB host. The controller separates USB enumeration and transfer functions from ATA and ATAPI device commands, reducing the need to place a host controller beside the storage interface. Its specified 0-to-70 C operating range suits systems whose internal ambient remains inside that envelope. Layout should preserve controlled-impedance USB routing and provide stable 3.3 V power, while software must be validated against the attached industrial media and control software.
Kiosk and Self-Service Peripherals
The CY7C68320C-100AXA is applicable to kiosks, self-service terminals, and payment-adjacent peripherals that rely on ATA-compatible removable media or legacy storage hardware. The USB side allows the host processor to manage the device through USB 2.0, while the ATA/ATAPI side supports direct attachment of compatible storage. A dedicated bridge can simplify enclosure wiring compared with exposing a parallel ATA bus to the main board. For public installations, enclosure temperature, media reliability, USB connection security, and operating-system support should be addressed during system validation.
Legacy Equipment Modernization
Equipment modernization projects can place the CY7C68320C-100AXA between an existing ATA-based subsystem and a USB-capable controller. This arrangement allows a proven storage mechanism to remain in service while the external connection changes to USB 2.0. The device's EZ-USB AT2LP identity and ATA/ATAPI function make it appropriate where a direct USB-to-serial converter would be functionally incorrect. The migration should include complete pinout, timing, power, media, and operating-system checks rather than relying on package similarity alone.
ATA Media Diagnostics and Recovery
The CY7C68320C-100AXA can serve as the interface in service equipment intended to access ATA-compatible media for initialization, diagnosis, or recovery. USB 2.0 provides a practical connection to a service computer, and the dedicated ATA/ATAPI interface supports the device commands expected by the media. The controller does not itself make every drive recoverable, so compatibility must be tested with the exact media generation and command set. Thermal management, ESD protection, and safe connector sequencing remain important in a service enclosure.
Embedded USB Storage Gateway
An embedded gateway can use the CY7C68320C-100AXA when it must present ATA-compatible storage through USB to a host processor. The dedicated bridge role reduces the host's need to generate ATA signals directly, while full-speed and high-speed USB operation supports the two principal USB 2.0 transfer modes. The 100-TQFP footprint requires careful fanout and short routes for storage-side signals. Firmware should validate descriptors, media initialization, disconnect behavior, and recovery from host or bus resets for reliable unattended operation.

डिज़ाइन नोट्स
Route the USB D+ and D- conductors as a controlled-impedance differential pair from the connector or transceiver interface to the corresponding controller pins. Match length and maintain continuous reference-plane geometry to minimize skew and reflections. Keep ATA and ATAPI traces away from the differential pair where practical, and minimize stubs created by test pads or unnecessary via transitions.
Build the 3.3 V rail around the supply limits and decoupling recommendations in the manufacturer datasheet. Place required local capacitors at the associated power and ground pins with short current loops, and provide adequate source current for the controller and attached interface circuitry. Verify startup and hot-plug behavior with the complete storage-device load rather than only the controller in isolation.
Treat the 100-pin TQFP layout as a high-speed mixed-interface design rather than a generic parallel bus. Check every ATA and ATAPI net for adequate edge-rate bandwidth, series termination requirements, and return-path continuity. Place protection devices where their capacitance will not compromise USB signal integrity, and validate the completed board across the intended storage-device and USB-host combinations.
Do not infer pin compatibility from a similar package or a similarly named controller. Confirm that the exact MPN, USB signals, ATA and ATAPI functions, control pins, clock requirements, supply rails, and exposed or auxiliary connections agree with the installed design. Also verify media compatibility and host enumeration behavior, because electrical pin compatibility alone does not guarantee interchangeable firmware behavior.
