CY7C65642-28LTXCT - USB 2.0 TetraHub Controller, 28-QFN | Infineon
The Infineon CY7C65642-28LTXCT is a USB 2.0 TetraHub controller from the EZ-USB HX2VL family, providing four downstream ports with one dedicated Transaction Translator (TT) per port in a 28-pin QFN (5x5 mm) package. It supports USB Full-Speed (12 Mbps) and High-Speed (480 Mbps) operation and integrates I2C and SPI interfaces for hub-configuration access. The device operates from a single 3.3V or 5V supply and is qualified for the commercial 0C to +70C temperature range. A USB hub is a class of interface IC that expands a single upstream USB port into multiple downstream ports while managing traffic scheduling, transaction translation between High-Speed and Full-/Low-Speed devices, and per-port power control. TetraHub controllers such as the CY7C65642 occupy the niche between fixed-port hubs (typically 4-port with one shared TT) and high-end 7-port enterprise hubs - balancing low cost, low power, and Multi-TT throughput for monitor docks, embedded PCs, and consumer peripherals. Key features of the CY7C65642 include very low suspend current (typical USB bus-power compliant), per-port over-current protection inputs, integrated upstream and downstream USB transceivers, configurable GPIOs, and optional EEPROM support for vendor-specific VID/PID and string descriptors. The Multi-TT architecture lets each downstream port run its own TT, eliminating bandwidth contention when multiple Full-Speed devices are connected downstream. Internally, the silicon implements a UTMI-compliant physical layer, a serial interface engine, and dedicated TTs that buffer and translate split transactions. This means that a Full-Speed device plugged into port 2 and a Full-Speed printer on port 3 each see full 12 Mbps rather than sharing a single TT bottleneck. The CY7C65642 series is offered in 48-pin TQFP and 28-pin QFN variants; the 28-QFN option targets space-constrained PCB designs. Typical applications include USB 2.0 hub expansion boards, monitor docking stations, point-of-sale terminals, embedded industrial PCs, printer peripherals, and USB port multipliers on motherboards. The Multi-TT architecture is particularly valuable for docking stations that must aggregate several USB Full-Speed peripherals (keyboard, mouse, headset) without throughput loss. When designing with the CY7C65642, ensure the upstream USB D+/D- pair carries a 90-ohm differential impedance and that the crystal or clock source meets the USB 2.0 jitter specification. Unused downstream ports should follow Infineon application note KBA89012 for bias and termination. Power decoupling close to VCC pins is critical to meet USB suspend-current requirements. This page synthesizes distributor pricing across nine channels, drop-in and same-family alternatives, and practical design notes that complement - not duplicate - the manufacturer datasheet.
CY7C65642-48AXC - 4-Port USB 2.0 Hub Controller | Infineon
The Infineon CY7C65642-48AXC is a very-low-power USB 2.0 HX2VL TetraHub controller with four downstream ports, an independent transaction translator for each port, and GPIO-configurable hub functions. The device supports a 3.15 V to 5.25 V operating range, 100 mA operating current, and 28 µA low-power current, while using a 48-pin 7 mm × 7 mm TQFP package. It is specified for the commercial 0 °C to +70 °C temperature grade. A USB hub controller is an interface IC that manages traffic between one upstream USB host connection and multiple downstream USB ports. Within the product hierarchy, this device is a USB interface controller, then a USB hub controller, then a USB 2.0 peripheral. Its HX2VL architecture is intended to isolate traffic and improve low-cost multi-port USB designs while minimizing external bill-of-material requirements. Verified product information identifies support for both full-speed and high-speed USB operation, two or four configurable ports, LED indicators, and EEPROM-based configuration. The four-port configuration uses GPIO options for port behavior and status indication. A 3.3 V or 5 V system design is possible within the verified 3.15 V to 5.25 V range, but individual downstream-port current limits, crystal requirements, signal-routing rules, and exact transceiver timing must be taken directly from the manufacturer datasheet. The CY7C65642 belongs to the HX2VL family, whose four-downstream-port option is optimized for low-power, high-performance USB hubs. Its 48-pin TQFP package is larger than the family's 28-pin QFN option, but the verified listing specifically identifies the 7 mm × 7 mm 48-TQFP configuration. The part is marked not recommended for new designs, and an Infineon community response identifies CY7C65630 and CY7C65631 as active alternatives for four-port designs; however, those candidates require package and pin-level review before being treated as replacements. Typical applications include four-port USB hubs, desktop and laptop docking products, printers, storage peripherals, industrial USB interfaces, and embedded USB expansion systems. In each case, the controller handles port enumeration and transaction translation while external power-switching, connector, clock, and passive components complete the system. PCB implementation should preserve the USB data-pair geometry specified by the manufacturer, place bypass capacitance near the supply pins, and account for the 100 mA device operating current separately from downstream-port loading. Because the lifecycle is NRND and verified drop-in replacements are limited, new USB hub designs should confirm firmware, firmware-independent configuration, pin compatibility, and supply requirements with Infineon before layout release.
CY7C65642-48AXCT - 4-Port USB 2.0 Hub | Infineon
The Infineon CY7C65642-48AXCT is a low-power USB 2.0 hub controller configured for four downstream ports, with Multi-TT operation, configurable GPIOs, LED indication, and EEPROM support. It is packaged in a 48-pin TQFP measuring 7 mm by 7 mm and supplied tape-and-reel in C-grade. A USB hub controller is an interface IC that connects one upstream USB host to multiple downstream ports and manages USB traffic, connection states, enumeration, and port-status reporting. Within the hierarchy of USB interface controllers, hubs, USB 2.0 devices, interface ICs, and semiconductors, the CY7C65642 family targets compact, low-cost systems requiring multiple USB ports. The verified manufacturer description identifies this device as a four-port Multi-TT USB 2.0 hub controller with configurable GPIOs, LED indicators, and EEPROM support. Infineon also describes the CY7C65642 portfolio as very low power and optimized for high-performance applications requiring as many as four downstream ports. The dedicated transaction translator architecture supports USB 2.0 hub operation while reducing system complexity. The device includes USB termination provisions described in the verified datasheet search result, including upstream pull-up support and downstream pull-down and series termination resistors. These integrated functions can reduce the number of external USB interface components and help designers simplify board layouts. The 48-pin TQFP also provides enough signal, configuration, and control connectivity for a four-port hub implementation. Typical uses include USB hubs in computers, docking stations, monitors, printers, embedded systems, test equipment, and industrial control systems. It is particularly suitable when a design needs four downstream USB connections, upstream high-speed and full-speed support, configurable port indicators, and EEPROM-assisted hub configuration. Designers should use the manufacturer datasheet for the exact electrical limits, clock requirements, pin names, USB routing guidance, decoupling recommendations, and supported configuration modes. PCB layout must preserve controlled-impedance USB pairs and minimize differential routing discontinuities. The verified lifecycle evidence also needs careful review because an Infineon community result identifies the related CY7C65642-48AXC as NRND.
CY7C68000-56LFXC - USB 2.0 Transceiver | Infineon
Infineon Technologies CY7C68000-56LFXC is a USB 2.0 transceiver with one transmit and one receive channel, packaged in a 56-pin QFN surface-mount package measuring 8 mm by 8 mm. The EZ-USB TX2 device family provides a high-speed serial USB interface alongside a parallel processor-facing interface, allowing USB connectivity to be added to systems whose host controller does not include a native USB transceiver. A USB 2.0 transceiver is an interface IC that converts between a serial USB differential signal and a parallel digital data path. Within the product hierarchy, it is a USB interface IC, an interface converter, and ultimately a semiconductor designed for data transfer. The relevant implementation level is the PHY-to-controller boundary, where transceiver signal integrity, clocking, data signaling, and parallel timing must be coordinated with the connected USB controller. Family documentation identifies a 16-bit parallel interface operating at 30 MHz or an 8-bit parallel interface operating at 60 MHz. These two operating modes support different balances between parallel-bus width and interface clock rate. The part also provides separate USB transmit and receive paths, allowing a parallel USB controller to manage bidirectional traffic over one USB 2.0 device connection. The CY7C68000 belongs to the Cypress EZ-USB TX2 transceiver family, a USB specification revision 2.0 product category. Its 56-QFN arrangement supports compact surface-mount layouts while exposing the parallel signals, power connections, control pins, and exposed thermal pad required for a complete USB transceiver implementation. The exposed-pad construction provides a thermal path into the PCB, making copper-plane design and solder-reflow process control important. Typical uses include USB connectivity for industrial control equipment, test and measurement instruments, embedded processors, printers, storage systems, and other compact USB 2.0 peripherals. The parallel interface is especially useful when the system controller has spare parallel I/O but lacks a native USB PHY. A controller-side clock, FIFO, or data engine must still handle protocol behavior because the transceiver provides the physical signaling interface rather than the complete USB host or device controller. For PCB implementation, place the transceiver close to the USB connector and route the differential pair as a short, continuous pair over a solid ground plane. Confirm the exposed-pad connection and thermal-via pattern in the manufacturer package documentation. Decoupling, clock-source tolerance, pull-up placement, and the required firmware or controller timing should be validated together before release. This page combines verified manufacturer-family information, distributor availability, package data, and drop-in replacement research. It also adds package-specific design guidance, application fit analysis, and parameter-by-parameter comparisons intended to support faster engineering selection without replacing the manufacturer datasheet or schematic review.
CY7C68000-56PVXC USB 2.0 Transceiver | Infineon
The Infineon Technologies CY7C68000-56PVXC is a USB 2.0 full-duplex transceiver IC for bridging USB to ATA or ATAPI storage devices. It is identified in distributor listings as the EZ-USB AT2LP USB 2.0-to-ATA/ATAPI bridge, supplied in a surface-mount 56-pin SSOP package measuring 7.50 mm wide. The device supports one CompactFlash connection and one ATA or ATAPI device, provides board-level manufacturing test access through the USB interface, and can place the ATA interface in a high-impedance state. 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.
CY7C68001-56LFXC - USB 2.0 ATA Controller | Infineon
Infineon Technologies CY7C68001-56LFXC is a USB 2.0 parallel-interface controller with an 8-bit or 16-bit datapath, supplied in a 56-QFN surface-mount package measuring 8 mm by 8 mm. The device operates from a 3.3 V supply and is designed to bridge a USB host to ATA/ATAPI storage equipment. Its verified feature set includes support for CompactFlash and one ATA/ATAPI device, board-level manufacturing-test operation through the USB interface, and a high-impedance ATA interface for sharing the ATA bus with another controller. 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.
CY7C68001-56LTXC USB 2.0 Controller | Cypress | 56-QFN
The Cypress Semiconductor CY7C68001-56LTXC is a USB 2.0 full-speed and high-speed USB interface device with a parallel interface, supplied in a 56-pin QFN package measuring 8 mm by 8 mm. It operates from a 3.3 V supply and is designed to add USB 2.0 connectivity to an external processor, DSP, ASIC, or FPGA. The device is also identified as the EZ-USB SX2 high-speed USB interface device and is commonly used to bridge USB 2.0 to ATA or ATAPI storage interfaces. An EZ-USB interface device is a dedicated USB connectivity and protocol-controlling component. In the product hierarchy, it is an interface IC, a USB controller, and ultimately a semiconductor designed to simplify USB peripheral implementation. Unlike a general-purpose microcontroller with integrated USB, the CY7C68001-56LTXC provides a dedicated parallel interface that allows an external master to manage USB transactions and peripheral functions without implementing the complete USB protocol stack in the host processor. The verified product information identifies USB 2.0 operation, full-speed and high-speed support, a 3.3 V operating supply, and a parallel interface to the external system. The package is a 56-pin QFN with an exposed pad and an 8 mm by 8 mm footprint. The device is also documented for Compact Flash and one ATA or ATAPI device, while its ATA interface can enter a high-impedance state so that the ATA bus may be shared with another controller such as IEEE 1394. The SX2 architecture is useful when an existing digital subsystem needs a dedicated USB interface rather than direct software control of USB low-level signaling. USB 2.0 full-speed and high-speed operation provide compatibility with common USB hosts and peripherals, while the parallel external interface separates the host-facing data path from USB protocol handling. The available 3.3 V supply requirement makes board-level integration straightforward for systems designed around contemporary 3.3 V digital logic. Typical applications include USB-to-ATA storage adapters, USB-to-Compact Flash readers, board-level manufacturing test fixtures, embedded USB peripherals, and systems using a microprocessor, DSP, ASIC, or FPGA as the external master. The exposed-pad QFN package supports compact PCB layouts, although correct thermal pad soldering and adequate copper are required for reliable heat dissipation. Designers should verify the complete pin assignment and signal timing against the manufacturer datasheet before layout. The parallel interface requires careful routing, and USB differential pairs should be routed as controlled-impedance connections with minimal stubs. For ATA implementations, power-state transitions, bus ownership, and high-impedance behavior must be coordinated with the external master to prevent contention. This page combines verified distributor identification, package and pricing information, pin-compatible substitution screening, application guidance, and practical implementation cautions. The comparison focuses on verified USB and packaging attributes while marking unreported electrical details for datasheet confirmation rather than estimating them.
CY7C68001-56PVXC - USB 2.0 Controller | Infineon
The Infineon Technologies CY7C68001-56PVXC is a USB 2.0 high-speed interface controller with an 8/16-bit parallel datapath, operating from a 24 MHz clock and housed in a 56-pin SSOP package. The device provides the USB-facing signal processing and transaction handling required to add USB connectivity to a design built around an external microprocessor, DSP, ASIC, or FPGA. 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.
CY7C68003-20FNXI - Full-Speed USB 2.0 | Infineon
Infineon Technologies CY7C68003-20FNXI is a full-speed USB 2.0 transceiver with one transmitter and one receiver, operating from a 1.8 V to 3.3 V supply in a 20-WLCSP package measuring 2.14 mm by 1.76 mm. The compact device provides the physical-layer signaling required to connect a USB 2.0 controller, processor, or peripheral to a USB connector. A USB transceiver is an interface IC that converts digital data from a host or device controller into USB differential signaling, and converts incoming differential signals into logic-level data. The USB transceiver belongs to the interface IC hierarchy, alongside USB controllers, serial transceivers, and line drivers. Its full-speed designation corresponds to USB 2.0 low-speed and full-speed operation rather than USB 2.0 high-speed operation. The verified product information identifies a one-driver, one-receiver configuration, a full-speed USB 2.0 interface, and a 1.8 V to 3.3 V supply range. These characteristics suit space-constrained portable equipment, industrial controllers, and USB peripherals that use low-voltage digital logic. The very small WLCSP footprint reduces board area but requires careful assembly and routing practices. The part's compact 20-WLCSP construction is suitable for high-density designs where connector placement, EMI control, and trace length are important. Because this is a physical-layer transceiver, system behavior also depends on the connected USB controller, pull-up or pull-down implementation, crystal or clock source, termination network, connector, and firmware configuration. The transceiver alone does not negotiate USB speed or implement the complete protocol stack. Typical applications include USB-to-serial adapters, embedded USB peripherals, portable instruments, industrial data-acquisition equipment, and compact control systems. In each case, the 1.8 V to 3.3 V operating range aligns with modern low-voltage processors, while the 2.14 mm by 1.76 mm footprint supports compact assemblies. A critical design consideration is PCB layout. USB differential traces should be routed as a controlled-impedance pair over a continuous ground plane, with minimized stubs and careful separation from switching nodes. The manufacturer's datasheet should be consulted for the exact ball assignments, exposed-pad treatment, recommended capacitors, and USB routing dimensions. This page combines verified supplier information, package and interface specifications, replacement-family references, pricing context, and practical USB PCB-design guidance to support faster component selection and design review.
CY7C68003-24LQXI - USB 2.0 ATA Bridge | Infineon | 24-QFN
Infineon Technologies CY7C68003-24LQXI is a full-speed USB 2.0 interface transceiver and EZ-USB AT2LP bridge that supports CompactFlash and one ATA/ATAPI device in a 24-QFN (4 x 4 mm) surface-mount package. It operates from a 1.8 V to 3.3 V supply over a -40°C to +85°C temperature range. The device provides the physical interface required to connect USB storage equipment to an ATA or ATAPI-compatible embedded controller. An EZ-USB AT2LP bridge is a specialized interface IC that translates between the USB 2.0 bus and an ATA/ATAPI storage bus. Within the product hierarchy, it belongs to the USB transceiver family, then to interface ICs, and finally to the broader semiconductor category. This bridge is intended to simplify USB-to-ATA product designs by combining USB signaling and ATA-side control in one compact package. Key verified features include full-speed USB 2.0 operation, support for CompactFlash and one ATA/ATAPI device, and board-level manufacturing test through the USB interface. The ATA interface can also be placed in a high-impedance state, allowing the ATA bus to be shared with another controller such as an IEEE-1394 controller. Its 24-QFN package supports compact PCB layouts while the exposed pad provides a thermal connection to the board. The CY7C68003 family separates USB connectivity from the storage-facing ATA interface and is intended for board-level embedded storage designs. Board-level manufacturing test is especially useful because production fixtures can exercise the attached storage path over USB instead of requiring a separate ATA test interface. The shared-bus capability also provides a route to designs in which USB and another transport must coexist. Typical applications include USB CompactFlash readers, USB-to-ATA storage adapters, embedded industrial data loggers, portable diagnostic equipment, board-level storage subsystems, and legacy ATA peripheral modernization. These systems benefit from a single USB-facing interface while retaining compatibility with CompactFlash or ATA/ATAPI storage devices. Designers should account for the 1.8 V to 3.3 V operating range, the -40°C to +85°C industrial temperature rating, exposed-pad layout, USB routing, and ATA signal-integrity requirements. The datasheet-supported high-impedance ATA mode must be coordinated carefully whenever multiple potential bus controllers share the ATA side. This page consolidates verified distributor information, same-family replacement options, package details, and application-specific engineering guidance. It distinguishes genuine same-footprint alternatives from cross-package parts that would require PCB redesign, helping engineers make a replacement decision based on fit, function, sourcing, and thermal requirements rather than part-number similarity alone.
CY7C68300A-56PVC - USB 2.0 to ATA Bridge | Infineon
Infineon Technologies CY7C68300A-56PVC is a USB 2.0 to ATA/ATAPI interface controller with 56 pins, a 3.3 V supply, and a 56-SSOP package. It bridges a USB host connection with legacy ATA storage, providing a practical migration path for embedded systems that must retain parallel ATA storage support. The device is identified as an EZ-USB AT2 USB 2.0-to-ATA bridge in the available manufacturer-linked data. 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.
CY7C68310-80AXC USB 2.0 ATA Bridge | Infineon
The Infineon Technologies CY7C68310-80AXC is a low-power USB 2.0 to ATA/ATAPI bridge integrated circuit with a 2.5 V operating supply identified in the verified results and an 80-pin TQFP package. It is designed to provide a bridge between a USB 2.0 host interface and ATA or ATAPI storage devices, making it suitable for embedded storage adapters, legacy computer peripherals, and systems that need protocol conversion without implementing the complete storage interface in host hardware. The verified sources identify the part as an ISD-300LP Low-Power USB 2.0 to ATA/ATAPI Bridge IC. A USB-to-ATA bridge is an interface controller that translates USB commands and data traffic into ATA/ATAPI commands and electrical signaling. In the device hierarchy, it belongs to interface ICs, then data converters and bus bridges, and finally the broader semiconductor category. The bridge can help preserve investment in storage mechanisms designed around parallel ATA while adding a USB connection for a newer host system. Its low-power designation is important for portable and embedded equipment where USB connectivity must not dominate the system power budget. The available verified data confirms the key identity and package information: CY7C68310-80AXC, USB 2.0, ATA/ATAPI bridge operation, 2.5 V supply information, and an 80-pin TQFP package measuring 12 x 12 mm according to the DigiKey result. The search results also identify the device as an Infineon/Cypress component through distributor and Octopart listings. Detailed electrical limits, transfer-rate values, operating-temperature limits, and timing parameters were not supplied in the verified snippets, so those values must be confirmed from the manufacturer datasheet before a design is released. Typical uses include USB storage adapters, embedded data loggers, industrial equipment with legacy ATA storage, test fixtures, and computer systems that need a controlled bridge to an ATA device. In these applications, the bridge handles USB enumeration and storage-protocol translation while the host operating system presents the storage device through its normal USB mass-storage path. Designers should confirm host compatibility, device-side ATA signaling, power requirements, connector implementation, and operating-system support using the official CY7C68310 documentation. The most important design consideration is interface validation rather than raw substitution. A candidate part must match the 80-pin TQFP footprint, pin functions, supply requirements, USB behavior, ATA/ATAPI timing, and operating system requirements. The verified web results do not establish a qualified pin-to-pin replacement, so substitute parts should not be treated as drop-in without manufacturer documentation. This page distinguishes verified facts from missing technical data and emphasizes datasheet-based review. This product page combines the verified distributor identity, package information, pricing reference, and practical selection context with explicit markers for unavailable electrical specifications. It is intended as an engineering-oriented starting point for sourcing and design review rather than a substitute for the full manufacturer datasheet.
CY7C68320-100AXC - USB 2.0 to ATA Bridge | Infineon
The Infineon Technologies CY7C68320-100AXC is a USB 2.0 to ATA/ATAPI interface bridge controller packaged in a 100-lead LQFP. The device is designed to bridge a USB high-speed host connection to an ATA or ATAPI storage interface, reducing the need for a discrete host-controller and storage-interface implementation. The verified product records identify the device as a USB Bridge with a USB 2.0 ATA interface and a 100-TQFP package measuring 14 x 20 mm. A USB-to-ATA bridge is a storage-interface controller within the broader USB interface-controller and data-conversion IC hierarchy. Its primary role is to translate USB transactions and descriptors into ATA or ATAPI commands, allowing compatible storage equipment to appear as a USB peripheral. This device class is useful when legacy or removable storage interfaces must be connected through a standardized USB high-speed host port. The verified listings identify the CY7C68320-100AXC as a Cypress Semiconductor EZ-USB AT2LP USB 2.0 to ATA/ATAPI bridge. Related listings describe the corresponding CY7C68320C-100AXC as a 100-pin USB-to-ATA bridge, providing confirmation of the interface function, family positioning, and package format. The commercial-grade operating-temperature information listed for the closely identified CY7C68320C-100AXC is 0°C to 70°C, while the exact specification for the non-C target order code remains to be confirmed from its manufacturer datasheet. Architecturally, this controller sits between a USB host and an ATA/ATAPI storage device. USB provides the external connection and enumeration boundary, while ATA commands operate internally through the bridge's ATA-compatible interface. The integration can shorten firmware and hardware development for USB storage products by consolidating protocol handling in a dedicated controller instead of implementing the complete bridge function in a separate microcontroller. Typical use cases include USB-connected external storage, embedded data-logging systems, industrial storage adapters, legacy ATA equipment modernization, and test fixtures that require a USB front end for an ATA peripheral. In each case, system design must still provide the required USB termination, ATA signal routing, storage connector, power architecture, and firmware support for the selected device configuration. The primary design consideration is package verification. Distributor records alternate between CY7C68320-100AXC and CY7C68320C-100AXC, and the available search results do not provide a verified pin-by-pin comparison for every order code. Engineers should therefore confirm the exact MPN, pinout, electrical limits, supported ATA modes, and firmware compatibility against the applicable manufacturer datasheet before releasing a PCB or production order. This page consolidates verified distributor and manufacturer-document discovery records with package-aware selection guidance, practical integration considerations, and an explicit separation of confirmed facts from unresolved data. It is intended to accelerate engineering review while avoiding unsupported claims about lifecycle, pricing, pin assignments, or drop-in substitution.
CY7C68320-56LFXC - USB 2.0 ATA Bridge | Cypress
The Cypress Semiconductor CY7C68320-56LFXC is a USB 2.0 to ATA/ATAPI bridge controller with a 480 Mbps host interface, supplied in a 56-VFQFN package measuring 8 mm by 8 mm with an exposed pad. It is designed for systems that require an internal mass-storage connection between a USB host and an ATA or ATAPI device. The verified distributor information identifies the device as a USB Bridge with a USB 2.0 ATA interface and describes the original package as 56-VFQFN with an exposed pad. A USB-to-ATA bridge is an interface controller that translates USB traffic into the command, data, and status protocols expected by conventional storage devices. In the product hierarchy, this device is a USB interface IC, a USB-to-ATA bridge controller, and ultimately a semiconductor designed to reduce the host-controller burden of supporting legacy mass-storage peripherals. The bridge can therefore support storage-oriented equipment where an external USB connection must coexist with an internal ATA-style storage subsystem. The CY7C68320-56LFXC operates as a USB 2.0 high-speed peripheral-side controller at the stated 480 Mbps interface rate. Its 56-VFQFN package provides a compact surface-mount solution for densely populated embedded and industrial equipment. The exposed pad is an important thermal and electrical feature because it provides a direct connection between the device and the PCB copper beneath the package, subject to the manufacturer’s recommended land pattern and assembly requirements. The exact clocking, supply-voltage, current-consumption, operating-temperature, logic-level, and internal-controller details are not included in the supplied verified extracts and therefore cannot be stated reliably here. Designers should use the manufacturer datasheet for electrical limits, signal timing, ATA/ATAPI protocol details, oscillator requirements, and the complete exposed-pad layout. The verified material also contains closely related CY7C68320C-56LFXC and CY7C68321-56LFXC records, but those records should not be treated as identical without an engineering review of their respective datasheets and ordering information. Typical applications include industrial storage equipment, embedded data-acquisition systems, legacy computer peripherals, external-storage enclosures, and service or diagnostic systems that need a USB 2.0 bridge to an ATA/ATAPI device. The 480 Mbps USB interface offers materially greater headroom than the earlier USB 1.1 full-speed rate of 12 Mbps, while the dedicated ATA/ATAPI function avoids implementing that storage protocol directly in a host processor. PCB implementation should follow the exact exposed-pad land pattern and pin-assignment drawing in the manufacturer datasheet. The exposed pad should be connected to the appropriate supply or ground plane indicated by that drawing, with adequate via and copper area for thermal and electrical performance. Signal-routing and platform-interface details require verification because the supplied data does not include the complete pinout, recommended capacitors, or USB routing guidance. This page combines the verified distributor descriptions, package identification, availability information, source links, and qualified replacement data to support component discovery. It also distinguishes documented facts from fields requiring datasheet confirmation and avoids presenting unverified electrical claims as production specifications.
CY7C68321-100AXC USB 2.0 ATA Bridge | Cypress
The Cypress Semiconductor CY7C68321-100AXC is a fixed-function EZ-USB AT2LP USB 2.0 to ATA/ATAPI bridge integrated circuit in a 100-pin TQFP package. It provides one USB port and support for one or two ATA- or ATAPI-based devices, including CompactFlash storage, while offering an ATA interface high-impedance mode for shared-bus designs. The device is identified in the verified distributor data as a USB Bridge with a USB 2.0 ATA interface and a 100-TQFP (14 x 20 mm) package. The CY7C68321 belongs to the EZ-USB AT2LP family of USB storage interface controllers. An interface IC is a semiconductor category used to connect host buses and peripheral protocols; in this case, the bridge translates the USB 2.0 host interface into ATA/ATAPI signals used by compatible storage devices. Its position within the broader hierarchy is interface IC, then USB interface controller, then fixed-function USB-to-ATA bridge. Verified listing information identifies the part as a 480 Mbps USB 2.0 interface solution with a 3.15 V minimum and 3.45 V maximum operating voltage. The ATA side can support CompactFlash and one ATA/ATAPI device. Its high-impedance ATA interface is useful when another controller, such as an IEEE 1394 device, must share the ATA bus. These details make the bridge relevant to legacy USB storage appliances, embedded ATA systems, and CompactFlash equipment. The 100-pin TQFP package provides the board interface required for host, storage, power, control, and signal-conditioning connections. Because this legacy bridge targets USB 2.0 and ATA/ATAPI rather than modern USB storage standards, designers should verify host operating-system support, device compatibility, signal integrity, power sequencing, and connector requirements before releasing a new design. The verified distributor pages do not publish detailed timing, thermal, or environmental values, so those parameters remain to be confirmed from the manufacturer datasheet. This page consolidates the verified product identity, package information, sourcing links, interface capability, and engineering selection criteria. It also distinguishes confirmed facts from parameters that require datasheet verification, helping engineers evaluate the CY7C68321-100AXC without treating catalog snippets as a complete electrical specification. Designs should reserve adequate placement and routing flexibility for the 100-pin TQFP footprint, validate the ATA and USB signal-integrity requirements, and confirm device-support policy before production. For a new USB-to-ATA product, assess whether a modern USB mass-storage controller provides better long-term platform support. For maintaining an existing ATA/CompactFlash design, the bridge may remain suitable if its timing, power, and compatibility requirements are unchanged.

A capacitive touch controller is a specialized input interface IC that detects changes in capacitance caused by a user's finger or conductive object. It belongs to the broader capacitive-sensing controller category, which combines analog front-end measurement, configurable button logic, and digital communication. Unlike a mechanical switch, a CapSense controller can provide sealed user interfaces, compact layouts, and configurable behavior without exposing moving electrical contacts. The CY8C20110 supports four to ten capacitive buttons through its 10 CapSense I/O resources. Its I2C interface provides a straightforward connection to a host microcontroller for configuration and status communication. Configuration is stored in onboard nonvolatile memory so that the controller can load its operating configuration automatically at power-on. The device is also optimized for LED dimming in backlight applications through 15 selectable duty cycles. The CY8C20110-SX2I combines sensing and control functions without requiring a separate host processor to perform basic touch detection. Its operating range of 2.4 V to 2.9 V suits low-voltage embedded systems where supply headroom is constrained. The industrial temperature rating of -40°C to 85°C supports operation across commercial and industrial ambient environments when the complete assembly is designed and tested for those conditions. Typical uses include appliance control panels, compact capacitive keypads, lighting controls, backlight dimming interfaces, and embedded touch buttons. In a keypad, multiple CY8C20110 I/O resources can support individual electrodes, while the host reads touch events over I2C. The device is particularly useful when the mechanical design requires a flush panel, sealed enclosure, or a product appearance based on illuminated capacitive controls rather than discrete switches. Designers should account for electrode geometry, guard components, environmental compensation, connector capacitance, and the effect of enclosure materials. The I2C bus must also be checked for address availability and pull-up requirements on the assembled system. Because the verified product information does not provide a complete public pin map, PCB designers should use the manufacturer pinout and reference design rather than infer connections from the package outline. This page combines verified manufacturer and distributor information, package and interface constraints, drop-in alternatives, application guidance, and design notes. It highlights where the CY8C20110-SX2I fits within capacitive user-interface designs and where replacement decisions require additional firmware, firmware-compatibility, and board-level validation.
CY8C20111-SX1I - One-Button Capacitive Touch | Infineon
The Infineon Technologies CY8C20111-SX1I is a CapSense Express capacitive-touch controller for one touch button, featuring one general-purpose output and I2C/2-Wire connectivity in an 8-SOIC package. It is designed for compact human-interface applications where a single touch target must be detected reliably without a mechanical switch. The verified product data identifies the device as an 8-pin SOIC capacitive-touch controller; detailed electrical ratings and timing values require the manufacturer datasheet. A capacitive-touch controller is an integrated circuit that measures changes in capacitance caused by a conductive surface, typically a copper button or pad, and converts that change into a digital output. The CY8C20111 belongs to the broader hierarchy of capacitive sensing integrated circuits, touch controllers, interface controllers, and embedded mixed-signal semiconductors. CapSense controllers are useful in appliance controls, access panels, medical equipment, and industrial interfaces where sealed or low-profile controls are preferred. The verified listing identifies the CY8C20111 as the one-button member of the CapSense Express family. The same source states that CY8C20121 supports two capacitive sensing buttons and two general-purpose outputs, while CY8C20111 supports one capacitive sensing button and one general-purpose output. This distinction is important when comparing the devices: the one-button CY8C20111 may be the simpler choice for a single touch zone, whereas CY8C20121 provides additional sensing and output resources. The I2C/2-Wire interface allows the controller to participate in a host-controlled embedded system rather than operating as a completely independent user interface. Designers should confirm host address, serial timing, pull-up requirements, firmware behavior, and electrical limits against the manufacturer datasheet before finalizing the interface. The 8-SOIC package supports conventional surface-mount assembly, although the verified material does not provide dimensions or pin numbering. Typical use cases include touch panels for household appliances, compact control modules, equipment front panels, and low-profile controls where a conventional mechanical switch would be undesirable. The capacitive sensing electrode should be designed with the controller’s recommended layout, guarding, shield, and grounding techniques. Environmental factors such as moisture, nearby conductors, enclosure materials, and human-body loading can affect sensor performance. The CY8C20111-SX1I is best suited to designers seeking a dedicated one-button touch controller with serial connectivity in an established SOIC footprint. Before purchasing, verify current lifecycle status, pricing, availability, temperature range, supply voltage, operating current, output timing, and the exact pinout using the latest manufacturer documentation. This page combines verified distributor identification, package and interface information, source traceability, and application guidance. It does not infer electrical limits, pricing, pin names, or compliance claims that are absent from the supplied data.

It combines capacitive sensing, GPIO functions, LED-driving capability, interrupt support, 2 kbit flash memory, and 512 bytes of RAM in one compact controller. The verified distributor listing identifies the device as a 16-SOIC capacitive-touch button controller, while an indexed datasheet excerpt describes configurable I/O for sensing buttons or driving LEDs and interrupts. A capacitive-touch controller is a semiconductor that detects changes in capacitance caused by a user touching an external conductive pad. In the broader hierarchy, the CY8C20140 belongs to capacitive sensing controllers, interface ICs, and embedded control devices. Its sensing algorithm is designed for high sensitivity and low noise, with claimed immunity to RF and AC noise and low radiated EMC noise. This makes it useful where physical buttons must remain reliable on sealed, compact, or cosmetic control surfaces. The device supports applications with four, six, eight, or ten capacitive inputs according to the verified product description, although the selected CY8C20140 listing is specifically categorized as a 16-SOIC part. Firmware and configuration are handled through an I2C interface, and configuration can be stored in onboard nonvolatile memory for automatic loading at power-on. The available data identifies 2 kbits of density and 2 KB of flash storage; these values are retained exactly as provided rather than inferred into unsupported detail. The controller is suitable for appliance control panels, access controls, audio equipment, industrial interfaces, and consumer products. A four-button panel can use the configurable I/O for sensing electrodes or auxiliary functions, while the host processor reads status and handles higher-level behavior. Designers should confirm the exact pin functions, electrical limits, configuration procedure, and application circuit from the manufacturer datasheet before layout or firmware release. PCB implementation requires careful sensor-electrode geometry, grounding, shielding, and separation from noisy switching nodes. The available verified excerpts emphasize broad support for sensor capacitance, sensor shapes, sensor sizes, and noise immunity, but do not provide enough data to state precise layout dimensions or timing values. Use the manufacturer guidance for those details rather than extrapolating from generic touch-controller layouts. This page consolidates distributor availability, manufacturer-oriented search results, indexed datasheet excerpts, and replacement research for CY8C20140-SX2I. The supplied evidence does not include a current unit price, complete pinout, or verified list of same-package substitutes; those gaps are explicitly marked instead of being filled with guesses.

One verified distributor listing identifies 2 kbits of device memory, while another describes 512 bytes of RAM and PWM capability. The SOIC-8 package provides a compact surface-mount footprint, and the -40°C to 85°C range supports industrial-temperature designs. The device combines a small embedded controller with configurable sensing and GPIO resources. Its four channels can be allocated according to the interface requirements of the product, while the I2C interface allows a host microcontroller or system controller to configure and monitor touch events. Because it is a dedicated CapSense Express controller rather than a general-purpose MCU, it can reduce the sensing burden placed on the primary embedded processor. Typical applications include appliance control panels, industrial touch buttons, equipment interfaces, consumer products, and low-cost human-machine interfaces. A connected host can read button states over I2C, update LED indicators through selected GPIOs, and respond to user input without dedicating a separate analog front end to capacitance measurement. PCB layout is critical for reliable capacitive sensing. The sensing electrodes, their connecting traces, ground structures, and enclosure materials influence sensitivity and stability. Designers should follow the manufacturer's pinout and application guidance, keep sensitive routes short, provide a stable ground reference, and evaluate the complete mechanical and electrical environment rather than treating the controller as a conventional digital switch input. This page consolidates the verified manufacturer and distributor information for CY8C20142-SX1I and adds package-specific design guidance, parameter comparisons, and a same-family replacement analysis. The alternative assessment is intentionally conservative: only controllers documented as using the same package are treated as potential drop-in parts, and unsupported electrical details are marked as data needed rather than estimated.

Its small SOIC footprint helps preserve board area in compact products, while configurable I/O supports shared sensing and general-purpose control requirements. The I2C-related functionality mentioned in comparison data should be verified against the manufacturer datasheet before final firmware and PCB sign-off. Typical applications include appliance control panels, small consumer products, industrial interface modules, LED status indicators, and embedded keypad or button assemblies. For a new design, confirm the exact sensor geometry, electrode size, grounding, shielding, and firmware configuration using the manufacturer application guidance. The -40 °C to +85 °C range makes the part suitable for industrial-temperature indoor products when the surrounding enclosure and connector system are also qualified. A practical design consideration is to keep capacitive-sensing traces short and keep the touch electrode away from high-current switching nodes and noisy sources. The controller does not eliminate the need for careful analog layout, filtering, calibration, and environmental tuning. This page synthesizes verified distributor specifications, replacement research, package information, and practical integration guidance while clearly separating missing datasheet details from confirmed values.

PCB designs should preserve the documented I2C pull-up arrangement and provide appropriate grounding and sensor-layout practices for stable capacitive measurements. This page consolidates verified distributor listings, manufacturer-family datasheet information, a strict drop-in alternative review, application guidance, and practical design notes. It is intended to help engineers evaluate procurement, compatibility, and implementation requirements without relying on a single retail listing.
