CY7C65632-48AXCT - HX2VL USB 2.0 4-Port Hub Controller | Infineon
CY7C65632-48AXCT

CY7C65632-48AXCT - HX2VL USB 2.0 4-Port Hub Controller | Infineon

The Infineon CY7C65632-48AXCT is a Very Low-Power USB 2.0 Hub Controller from the HX2VL family, supporting up to four downstream ports with integrated upstream and downstream transceivers, a USB Serial Interface Engine (SIE), USB Hub Control and Repeater logic, and Transaction Translator (TT) logic. It operates from a 3.15 V to 5.25 V supply, ships in a 48-pin TQFP (7x7 mm) package, and is qualified for the 0 to 70 C commercial temperature range. The part is supplied on Tape and Reel (TR) in the 48-AXC shipping form. A USB 2.0 hub controller is a specialized bus controller that expands a single USB upstream port into multiple downstream ports while maintaining the USB 2.0 protocol envelope. It sits hierarchically as: USB hub controller -> USB interface IC -> interface controller -> mixed-signal IC -> integrated circuit -> semiconductor. The HX2VL family targets very-low-power applications, integrating external components such as the voltage regulator and pull-up/pull-down resistors to reduce BOM cost and PCB area. Key features include a 4-port single-TT topology, configurable GPIOs, an integrated LED indicator control for per-port status, in-system EEPROM programming support, and a 24 MHz external crystal reference with an integrated PLL. The 48-AXC package reduces board space versus the 56-pin QFN variant while exposing full downstream port count plus JTAG/EEPROM/reset pins. The integrated upstream termination, integrated 1.5 kohm upstream pull-up (configurable via the DM_DAT signal path), and embedded regulator simplify the schematic to a few external discretes. From an architectural perspective, the HX2VL combines a USB 2.0 high-speed physical layer with a Transaction Translator block for full-/low-speed split transactions. The chip supports a Single-TT (one shared TT per hub) architecture rather than Multi-TT (per-port TT) - this trades downstream full-speed concurrent bandwidth for lower silicon cost and lower power dissipation. Per Infineon datasheet, the embedded regulator provides a 3.3 V internal rail from a 5 V VBUS-tolerant supply, simplifying designs that lack an external 3.3 V LDO. Typical applications include USB 2.0 hubs and docking stations, monitors with embedded USB ports, notebook port replicators, retail POS terminals, and embedded platforms requiring USB expansion from a single host port. Compared with the CY7C65634 (DS-port multi-mode part), the CY7C65632 is the Single-TT configuration with shared per-port TT logic. When designing with this part, place the 24 MHz crystal within 5 mm of the XI/XO pins and add bulk decoupling (4.7 uF plus 0.1 uF) close to VCC. Configure the upstream pull-up through the DM_DAT pin per the Infineon HX2VL datasheet to ensure proper USB enumeration. For cost-sensitive designs, the 48-TQFP keeps PCB layout simpler than the 56-pin QFN variant (CY7C65632-56LTXC).

CY7C65634-28LTXC - 2-Port USB 2.0 Hub Controller | Infineon
CY7C65634-28LTXC

CY7C65634-28LTXC - 2-Port USB 2.0 Hub Controller | Infineon

The Infineon CY7C65634-28LTXC is a two-port Single-TT USB 2.0 hub controller supporting Low Speed, Full Speed, and High Speed USB devices in a 28-pin QFN package. It operates from a 4.75 V to 5.25 V supply, supports a 0 °C to 70 °C temperature range, and is configurable through GPIO connections and an EEPROM. The C-grade designation identifies the exact ordering variant supplied in bulk packaging. A USB hub controller is an interface-controller semiconductor that manages traffic between one upstream USB host connection and multiple downstream ports. Within the hierarchy, this device is a USB interface controller, then a USB hub controller, then a USB 2.0 peripheral, and finally an integrated circuit. Its two-port Single-TT topology consolidates USB traffic-management functions while leaving port behavior configurable for compact external hubs, docking equipment, and embedded USB expansion. The verified product information identifies USB 2.0 operation, two downstream ports, Low Speed, Full Speed, and High Speed support, GPIO and EEPROM configurability, a 4.75 V to 5.25 V operating range, and a 28-QFN 5 mm by 5 mm package. Infineon describes the device as the EZ-USBTM HX2VL very-low-power USB 2.0 hub controller. The bulk shipping form and C-grade suffix distinguish it from the separately identified CY7C65634-28LTXCT tape-and-reel ordering option. Technically, the Single-TT architecture is significant because each downstream port receives dedicated transaction-traffic handling rather than relying on a shared legacy topology. That architecture helps the controller organize USB traffic while supporting devices operating across the USB 2.0 speed set. GPIO and EEPROM configuration also allow a product designer to adapt port behavior without treating the controller as a fixed-function hub. Typical uses include compact USB hubs, USB docking stations, embedded computing systems, test equipment, and peripheral-expansion products. The controller fits designs that need one upstream USB connection and two downstream ports while preserving support for both low- and high-speed USB devices. The primary design considerations are pin assignment, exposed-pad thermal management, USB routing, power distribution, and connector protection. Designers should use the manufacturer datasheet for the complete pin map, electrical limits, reference schematics, layout guidance, and configuration procedure rather than inferring these details from the distributor summary. This page combines the verified manufacturer description, distributor availability information, and explicitly identified ordering alternatives. It also separates confirmed product facts from parameters that require direct confirmation from the manufacturer datasheet, avoiding unsupported electrical or layout assumptions.

CY7C65634-48AXC - USB 2.0 Hub Controller | Infineon

The Infineon CY7C65634-48AXC is a 3.3 V USB 2.0 hub controller configured as a two-port single-TT hub, with integrated PLL, EEPROM support, GPIO configuration, port-status indication, and USB termination support in a 48-pin TQFP package. It is designed for USB hub designs requiring a compact, integrated controller for downstream port management. A USB hub controller is an interface IC within the USB interface-controller and USB connectivity hierarchy. It manages traffic between an upstream USB host and downstream USB ports, while coordinating enumeration, connection, suspend, resume, and port-status functions. The CY7C65634-48AXC is positioned for USB 2.0 hub applications, including peripheral expanders, embedded USB equipment, and multi-port connectivity products. The manufacturer identifies the device as the EZ-USBTM HX2VL USB 2.0 hub controller and specifies a two-port single-TT configuration. The supplied component data identifies a 3.3 V supply, 0 °C to 70 °C operating range, and a 48-pin TQFP package. The verified distributor listing additionally identifies USB 2.0 high-speed hub functionality and USB interface classification. Detailed electrical limits, GPIO mappings, crystal requirements, and timing parameters remain dependent on the manufacturer datasheet. The controller is suitable when a board needs more than one USB peripheral connection and must translate between an upstream host connection and downstream ports. Its integrated PLL supports clock-based USB operation, while EEPROM support can assist with configuration storage. GPIO configurability allows the hub implementation to address port indicators and application-specific routing, although the exact supported pin functions must be verified from the device documentation. Typical design considerations include correct USB trace impedance, short matched routing between controller and connectors, careful handling of upstream and downstream differential pairs, and decoupling of the 3.3 V supply. The 48-pin TQFP package also requires a footprint and land pattern that match the manufacturer’s mechanical drawing; the conflicting package information in third-party listings should not be substituted for the manufacturer package designation. This page combines the verified manufacturer identity, distributor classification, package information, temperature range, supply voltage, and USB hub positioning with engineering guidance. It does not infer unavailable electrical limits, pricing levels, or replacement parts that are not confirmed by the supplied data.

CY7C65634-48AXCT

CY7C65634-48AXCT - USB 2.0 2-Port Hub | Infineon

The Infineon CY7C65634-48AXCT is a low-power USB 2.0 hub controller with a 2-port Single-TT hub configuration and low-speed, full-speed, and high-speed USB support. It is supplied in a 48-pin TQFP measuring 7 x 7 mm and is packaged on tape and reel for automated assembly. The device is configurable with GPIOs, port indicators, and EEPROM support, making it suitable for compact USB expansion designs. A USB hub controller is an interface IC that coordinates communication between a USB host and multiple downstream USB devices. It belongs to the USB interface controller hierarchy within integrated circuits and provides the logic needed to detect attachments, arbitrate bus access, and route USB traffic. The CY7C65634-48AXCT is intended for USB 2.0 hub implementations where low system complexity and a small controller package are priorities. The verified product information identifies the part as an EZ-USB HX2VL USB 2.0 hub controller. Its configurable GPIO resources can support hub-status or port-indicator functions, while EEPROM support allows firmware-related configuration storage. The low-power design is aimed at minimizing system power requirements in embedded USB products such as host adapters, docking equipment, and peripheral expansion systems. The device supports USB low-speed, full-speed, and high-speed operation, as identified by distributor listings and the manufacturer product-page description. A 48-pin TQFP provides a conventional surface-mount footprint with gull-wing leads, while the 7 x 7 mm body supports compact board layouts. The exact pin names, electrical limits, clock requirements, and timing values require confirmation from the manufacturer datasheet. Typical applications include two-port USB hubs, USB docking products, embedded host systems, and USB-to-USB expansion boards. In a two-port hub, the controller interfaces with an upstream USB host and manages downstream port attachment and status. Designers should preserve the required USB trace geometry, provide correct upstream and downstream connection routing, and verify all power and signal details against the manufacturer datasheet before layout release. The key design consideration is the distinction between a verified feature claim and an unverified electrical parameter. This page uses the supplied manufacturer and distributor information for port configuration, package, USB speed support, packaging, and sourcing, while marking detailed technical parameters as data needed rather than estimating them. The CY7C65634-48AXCT is therefore best evaluated as a USB 2.0 hub-controller platform for compact multiport USB products. This page combines verified distributor and manufacturer information with engineering-focused selection guidance, comparison fields, and practical USB hub design notes. It is intended to help engineers identify the correct controller and validate PCB, power, firmware, and compatibility requirements without substituting assumptions for unavailable datasheet values.

CY7C65640A-LFXC

CY7C65640A-LFXC - USB 2.0 Four-Port Hub Controller | Infineon

The Infineon Technologies CY7C65640A-LFXC is a USB 2.0 four-port high-speed hub controller packaged in a 56-QFN 8 mm × 8 mm package. The verified distributor data identifies USB 2.0 connectivity, four downstream ports, controller functionality, and USB-interface classification. Its supported host-side interface, integrated USB termination, and hub architecture are documented by the manufacturer datasheet. The available verified data does not provide the complete electrical timing table, so parameters not explicitly supplied are identified separately rather than inferred. A USB hub controller is a dedicated interface semiconductor that manages one upstream USB connection and multiple downstream ports. It belongs to the USB interface controller hierarchy: USB 2.0 controller → USB hub controller → interface IC → semiconductor. In a four-port hub, the controller coordinates traffic between a host and attached peripherals while providing device-side connection management, enumeration support, and integrated signal-conditioning resources described in the manufacturer documentation. The CY7C65640A-LFXC is positioned for USB 2.0 hub implementations where four downstream ports are required in a compact surface-mount design. The 56-QFN package supports dense PCB layouts, while the integrated USB termination resources can reduce the number of external resistors when the recommended reference design is followed. The verified Cypress comparison data describes the A-LFXC revision as functionally and pin equivalent to the earlier CY7C65640-LFXC, providing a documented same-family migration path. The controller is suitable for standalone hubs, motherboard hubs, docking stations, and other USB expansion systems. For high-speed signal integrity, the PCB layout must preserve controlled-impedance differential pairs, provide adequate return paths, and keep connector and routing geometry consistent with the manufacturer reference design. External power-distribution design is especially important because a four-port hub may need to supply more current than a single integrated USB port. The verified comparison data also identifies CY7C65640A-LTXC as a related family member. That part should not be treated as a drop-in replacement without checking its exact package suffix and ordering configuration. The A-LFXC suffix is especially important because package, temperature, lead style, and lifecycle details are encoded in the ordering code. This page synthesizes the verified distributor listings, manufacturer-linked datasheet information, and cross-reference results into a procurement-oriented overview. Electrical values that were not present in the supplied verified data are intentionally marked as required rather than guessed. The manufacturer datasheet remains the controlling reference for pin functions, timing, electrical limits, reference circuitry, and USB compliance testing.

CY7C65640A-LFXCT

CY7C65640A-LFXCT - USB 2.0 4-Port Hub Controller | Infineon

The Infineon Technologies CY7C65640A-LFXCT is a USB 2.0 four-port hub controller designed for embedded USB expansion, using a 3.3 V supply and a 56-QFN package measuring 8 mm by 8 mm. It consolidates multiple USB connections through one host interface, making it suitable for compact industrial, networking, and embedded systems where connector count and board space are constrained. A USB hub controller is an interface IC within the USB interface-controller family of semiconductor devices. It manages traffic between one upstream USB connection and multiple downstream ports, providing the electrical and protocol foundation for a USB hub. The CY7C65640A-LFXCT therefore belongs to the broader USB interface, connectivity IC, and semiconductor product hierarchy rather than acting as a general-purpose processor or memory device. The verified product information identifies USB 2.0 operation, four-port hub operation, a 3.3 V supply, and a 56-QFN 8 mm by 8 mm package. Its integrated hub-controller role allows a system designer to add multiple USB connections without implementing every USB data path with discrete logic. The surface-mount package also supports compact PCB layouts, although thermal, routing, and exposed-pad requirements must be confirmed from the manufacturer datasheet before layout release. This part is listed as obsolete in the supplied comparison data. Engineers should therefore treat it as a legacy component intended primarily for maintaining or reproducing an existing design rather than for a new platform with long-term procurement requirements. Its four-port USB hub architecture may remain useful in legacy peripherals, embedded equipment, and industrial systems that require a dedicated USB 2.0 hub controller instead of a general-purpose companion controller. Typical design roles include USB port expansion in embedded appliances, multi-interface industrial equipment, compact peripheral systems, and communication equipment that must expose several USB connections. A USB-to-serial bridge such as CP2102N can sit downstream when an external UART or programming interface is required. The actual host-driver, enumerator, power-supply, and port-protection implementations must be validated against the original system design and the manufacturer documentation. The primary design concern is ensuring that the upstream and downstream USB routing, supply voltage, decoupling, and thermal layout reproduce the original implementation. Because the available verified data does not specify the complete pinout, exposed-pad connection, operating temperature, USB data rates, and electrical timing characteristics, those values should be obtained from the manufacturer datasheet before making a drop-in decision. This page combines the verified distributor identification, lifecycle observation, same-package cross-reference result, commercial source links, and practical replacement guidance. It is intended to help engineers identify the CY7C65640A-LFXCT, assess whether a listed alternative is suitable, and locate the source data needed for a controlled legacy-design review.

It operates from 3.15 V to 3.45 V and is specified for a 0 °C to 70 °C ambient temperature range. The controller is designed for embedded USB hub designs requiring full-speed and high-speed USB connectivity. A USB hub controller is an interface IC that manages one upstream USB connection and multiple downstream ports. It belongs to the hierarchy of USB interface controller, interface IC, and semiconductor. The controller coordinates USB signaling, port attachment, downstream status, and hub power-management functions, allowing external USB devices to share a host interface through a controlled internal hub. The CY7C65640A-LTXC integrates 1.5 kΩ upstream pull-up resistors for full-speed operation, 15 kΩ downstream pull-down resistors, and series termination resistors on USB D+ and D- pins. It also supports an external 24 MHz crystal with an integrated PLL, in-system EEPROM programming, and integrated port-status indicator control. These features reduce the number of external USB termination components and support deterministic clocking for USB data transfer. The device is packaged in an 8 mm × 8 mm, 0.90 mm-high MO-220 QFN-56 package. The verified source identifies integrated upstream and downstream termination resistors, external crystal support, integrated PLL, and in-system EEPROM programming as principal features. Exact hub-port current limits, transceiver timing values, and programming details are not included in the supplied data and should be confirmed in the manufacturer datasheet before design release. Typical applications include USB hubs, USB monitors, docking stations, industrial USB interfaces, peripheral connection panels, and embedded USB expansion systems. The 0 °C to 70 °C range is appropriate for commercial-temperature equipment rather than automotive or extended industrial environments. Designers should preserve the specified 3.3 V supply range and validate USB routing, crystal requirements, thermal performance, and hub power budgets on the final PCB. The key design consideration is that this controller is an obsolete TetraHub product according to the supplied community result. New designs should confirm lifecycle status with the manufacturer or an authorized distributor, while existing designs should compare any proposed replacement against pinout, USB electrical behavior, firmware requirements, and power-management functions. This page synthesizes verified source information, practical design constraints, and replacement-search findings rather than presenting unverified substitute specifications.

CY7C65640A-LTXCT USB 2.0 Hub Controller | Infineon

The Infineon Technologies CY7C65640A-LTXCT is a high-speed USB 2.0 hub controller with integrated USB interface functions, available in a 56-QFN 8 x 8 mm package. The device is designed for systems that need to manage multiple USB downstream connections through a single USB host interface. According to the verified distributor listings, it operates from a 3.3 V supply and is specified for a 0 to 70 C operating-temperature range. A USB hub controller is an interface IC within the broader USB interface-controller and semiconductor hierarchy. Its primary role is to coordinate data traffic between one upstream USB connection and downstream USB ports, while adding hub-specific signaling, port management, and integrated termination functions. The CY7C65640A family is associated with the Cypress TetraHub high-speed USB hub controller product line and includes features such as integrated upstream and downstream termination resistors, integrated PLL operation with a 24 MHz crystal, port-status indicator control, and in-system EEPROM programming. The verified data identifies the target as a USB 2.0 hub controller with a 56-QFN package measuring 8 x 8 mm and approximately 0.90 mm in height. The MO-220 package designation and 56-pin count are important for PCB footprint matching. The integrated termination resistors can simplify board design by reducing external component count on USB differential pairs, while the integrated PLL supports clocking from an external 24 MHz crystal. Typical applications include USB hubs in computers, peripherals, docking systems, industrial equipment, and other USB expansion products. The controller is suitable where an upstream USB host connection must be distributed across multiple downstream ports. Designers should confirm the complete electrical characteristics, pin assignments, port configuration, clock requirements, and power-distribution limits in the manufacturer datasheet before finalizing a new PCB or using the part as an obsolete-board replacement. The most important practical consideration is lifecycle management: the cross-reference information identifies CY7C65640A-LTXCT as obsolete, and the verified comparison data also reports the related CY7C65640A-LTXC as obsolete. Existing equipment may require a qualified cross-reference rather than an unverified substitution. This page distinguishes confirmed web-data facts from parameters that require datasheet verification and highlights the engineering value of comparing package, protocol, temperature, and availability information before procurement. For replacement planning, the verified Infineon community information identifies CY7C65630-56LTXC as appearing to have the same pinout and functionality, but it does not provide a formal manufacturer replacement table. CY7C65630-56LTXC is therefore treated as a qualified drop-in candidate requiring device-specific verification, while other same-family package references are not padded into the alternatives list.

CY7C65642-28LTXC USB 2.0 4-Port Hub Controller | Infineon

Infineon Technologies CY7C65642-28LTXC is a USB 2.0 TetraHub controller configured as a four-port Multi-TT hub, with support for GPIO and EEPROM configuration and I2C/SPI interfacing in a 28-QFN 5x5 mm package. It is designed for embedded USB hub, docking-station, monitor, and USB expansion applications requiring a dedicated hub controller. A USB hub controller is an interface IC within the USB controller and USB interface-controller hierarchy. It manages traffic between one upstream USB connection and multiple downstream ports, adding device attachment, enumeration, power-management, and routing functions to a USB system. The HX2VL architecture supports both two-port and four-port configurations, while configurable GPIO and EEPROM options allow system behavior to be tailored during design or manufacturing. The part is identified as a USB 2.0 controller with I2C and SPI interfaces and a 28-QFN package. Infineon describes the device as a four-port Multi-TT hub with a 5x5 mm package, supplied in tray packaging as a C-grade component. The -28 suffix denotes the 28-pin package option, while the LXC ordering suffix identifies the package, temperature, and grade configuration; exact electrical ratings must be confirmed in the manufacturer datasheet. Its principal engineering value is dedicated hub management rather than general-purpose host operation. A downstream peripheral attached to the hub can be enumerated through the hub's internal logic, while I2C or SPI connectivity provides a path for embedded configuration and control. GPIO configurability makes the controller useful where port behavior must respond to straps, firmware, or an external EEPROM rather than remain entirely fixed. Typical installations include USB-to-Ethernet adapters, multi-port docking stations, computer monitors, external storage enclosures, industrial test equipment, and embedded media or connectivity systems. The controller is most appropriate when a board requires several USB downstream ports and controlled hub behavior; a simpler USB switch or single-port peripheral interface may be sufficient when only one device must be connected. PCB design should preserve the exact 28-QFN land pattern, expose the documented configuration interfaces, and provide the power and signal-integrity implementation required by the USB 2.0 data paths. Because the supplied data does not provide complete pin assignments, electrical limits, timing tables, or USB certification details, those values must not be inferred from generic USB specifications. This page consolidates verified distributor and manufacturer information, distinguishes the tray-packed -28LTXC version from the separately listed tape-and-reel -28LTXCT version, and provides design guidance while flagging unavailable technical data for datasheet verification.

CY7C65642-28LTXCT

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.

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

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.

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.

CY7C68000A-56BAXC - USB 2.0 High-Speed Transceiver | Infineon

The Infineon Technologies CY7C68000A-56BAXC is a USB 2.0 MoBL-USB TX2 transceiver and serial-to-parallel interface controller that converts a serial USB link into either a 16-bit parallel bus operating at 30 MHz or an 8-bit parallel bus operating at 60 MHz. The device is supplied in a 56-VFBGA package measuring 5 mm by 5 mm, making it suitable for compact USB 2.0 controller and peripheral designs. A USB transceiver is the physical-interface portion of a USB controller. It manages differential data signaling between a host or peripheral controller and a USB connector while presenting a parallel bus to the surrounding digital logic. The CY7C68000A-56BAXC supports the USB 2.0 specification revision indicated by the manufacturer and accommodates two parallel-interface operating modes, allowing the host logic to balance bus width against clock rate. The principal functional features include USB 2.0 operation, serial and deserializer functions, and the dual 16-bit/30 MHz and 8-bit/60 MHz parallel-interface options. The 56-VFBGA package supports compact PCB placement while exposing the device through a high-density ball-grid footprint. Its operating details must be checked against the manufacturer datasheet for the exact voltage limits, temperature range, clocking requirements, and signal timing of the selected board revision. Technically, the part sits between a parallel USB controller engine and the external USB data path. Its serializer and deserializer functions translate between the differential serial USB signaling domain and the internal parallel data bus. At 30 MHz, the interface width is 16 bits; at 60 MHz, the interface width is reduced to eight bits. This two-mode architecture is valuable when a design must balance transfer throughput, clock speed, logic utilization, and signal-timing margin. Typical uses include USB 2.0 peripheral controllers, portable data-acquisition equipment, storage adapters, test and measurement systems, and compact external-access products. In these systems, the device can provide the protocol-facing transceiver layer while a separate controller or programmable logic fabric handles packet processing, descriptors, enumeration, and application-specific data transfer. Layout is the primary implementation concern for this device. Differential USB routing, ball-grid escape routing, controlled-length clock and data paths, solid ground and power distribution, and close placement of decoupling components should follow the manufacturer’s reference layout and stack-up guidance. Do not substitute generic USB routing practices for the device-specific schematic and layout recommendations in the datasheet. This page combines the documented USB 2.0 interface modes, 56-VFBGA packaging, lifecycle considerations, sourcing workflow, and drop-in compatibility review into an engineering-focused reference. It also distinguishes confirmed drop-in alternatives from merely similar interface controllers, helping designers avoid adopting a part that has a related function but lacks verified footprint and pin compatibility.

CY7C68001-56LFXC

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.

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.

The Infineon CY7C68003-20FNXIT is a single-transceiver USB 2.0 full-speed interface IC offered in a 20-ball WLCSP package measuring 2.14 mm by 1.76 mm. The device is identified as the MoBL USB TX3LP18, placing it in the low-power MoBL USB family. Its compact footprint supports designs where connector placement, board area, and routing distance strongly influence the overall USB interface layout. A USB transceiver converts between the serial data signaling used by a USB controller and the electrical signaling present on a USB connection. A full-speed USB transceiver operates within the USB 2.0 full-speed range and is intended for USB controllers or processors that implement the required USB protocol and data handling. The CY7C68003 provides one transceiver, allowing a single USB connection to be supported without a multi-port transceiver array. The principal feature of the CY7C68003-20FNXIT is its integration into one 20-ball WLCSP package. At only 2.14 mm by 1.76 mm, the package substantially reduces the routing area required by the interface circuit. The MoBL designation also indicates a design intended for mobile and portable applications where low power and compact implementation are important considerations. Exact operating voltage, current, temperature range, and I/O characteristics are defined in the manufacturer datasheet. This interface IC is suited to portable equipment, data-collection terminals, personal computer accessories, and other embedded USB products. In each case, the surrounding controller must contain a compatible USB device or host controller core, because the transceiver handles the physical interface rather than the complete USB protocol stack. Firmware determines enumeration behavior, descriptor handling, power management, and the supported USB class. PCB implementation requires careful treatment of the USB data and supply connections. Short, impedance-controlled routing from the transceiver to the USB connector minimizes reflections and susceptibility to external interference. Decoupling capacitance should be placed close to the relevant supply pins, while the ground structure should provide a low-impedance return path beneath and around the interface section. The WLCSP land pattern also requires assembly processes capable of handling very small pitch packages. Because the CY7C68003-20FNXIT is a dedicated interface component rather than a complete USB controller, designers should select it when USB host or device functionality already exists elsewhere in the system. This page combines the confirmed interface and package characteristics with practical guidance on routing, decoupling, assembly, component selection, and design trade-offs.

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.

It combines USB connectivity, programmable I/O, serial debugging, and an embedded microcontroller in one device. A USB peripheral controller is an application-specific integrated circuit that manages transactions between a USB host and attached peripherals. The CY7C68013A family belongs to the broader hierarchy of USB interface controllers, embedded microcontrollers, and semiconductor ICs. Its architecture lets designers implement custom USB devices, data-acquisition systems, test equipment, and human-interface devices without using a general-purpose host controller. The headline features include USB 2.0 high-speed operation at 480 Mbps, 16 KB of internal RAM, and 40 GPIOs in a 100-pin TQFP package. The integrated 8051 core provides firmware execution and peripheral control, while serial debug supports development and troubleshooting. The part is intended for non-battery-powered applications, making it suitable for equipment that can remain connected to an external USB power source. Technically, the controller organizes USB endpoint behavior, data transfer, and general-purpose I/O around its embedded processor. Its 16 KB RAM supports endpoint buffering and working memory, while the 40 GPIOs can connect status indicators, control signals, relays, displays, or external interface circuits. Compared with a discrete USB transceiver plus host-side controller arrangement, the integrated FX2LP architecture reduces board complexity and centralizes protocol handling in the same IC. Typical uses include USB data-acquisition equipment, protocol analyzers, logic-analyzer interfaces, test-and-measurement instruments, industrial control adapters, and custom USB peripherals. The 480 Mbps interface is particularly useful when transferring larger blocks of data between a PC and acquisition hardware while retaining dedicated GPIO for synchronization and control. PCB design should preserve short USB differential traces, provide correct impedance-controlled routing, and place supporting components close to their associated pins. Because the device combines a microcontroller and USB peripheral controller, firmware timing and endpoint configuration are as important as electrical layout. Validate suspend, resume, bus-powered, and externally powered operating arrangements during system validation. This product record combines manufacturer-level USB, memory, GPIO, package, and lifecycle information with drop-in replacement analysis and practical integration guidance. It helps engineers evaluate the CY7C68013A-100AXC for new designs and plan transitions where the original FX2LP device is no longer the preferred sourcing choice.

Infineon Technologies CY7C68013A-100AXI is a high-speed USB 2.0 peripheral controller with an enhanced 8051 core, 48 MHz operating frequency, 16 KB internal RAM, and 40 general-purpose I/O pins in a 100-pin TQFP package. The ROMless EZ-USB FX2LP architecture combines an integrated USB 2.0 transceiver, programmable endpoint logic, and a low-cost 8051 microcontroller to support data-transfer rates above 53 MB/s. An EZ-USB FX2LP USB microcontroller is a specialized USB interface controller that places a configurable USB peripheral, USB transceiver, and embedded 8051 processor on one device. Within the product hierarchy, it belongs to the USB interface controller class, then microcontrollers, then integrated circuits and semiconductors. Its principal advantage over a discrete USB system interface controller is that firmware can configure endpoint behavior, packet handling, and data routing without requiring a separate external USB transceiver. Key features include full-speed and high-speed USB 2.0 operation, 16 KB of internal RAM, 40 GPIO, an enhanced 8051 processor, and integrated USB transceiver circuitry. The controller supports multiple endpoint configurations, allowing a system to buffer data, perform local transformations, or separate streams before transferring them over USB. Its ROMless architecture leaves the final application firmware in external memory, which supports product-specific boot code, device identification, and configuration routines. The FX2LP architecture is designed for high-throughput peripheral applications where USB bandwidth is more important than general-purpose processor integration. Its 8051 core operates at 48 MHz, while the USB engine handles the protocol and transfer functions. Up to 16 KB of internal RAM provides working space for descriptors, endpoint buffers, status variables, and firmware routines. The 100-pin TQFP package also exposes substantially more GPIO and interface signals than compact 56-pin FX2LP variants. Typical uses include USB-to-serial adapters, logic analyzers, test and measurement equipment, data acquisition systems, custom USB peripherals, and industrial data-logging products. In a logic analyzer, the GPIO array can capture digital activity while the USB engine transfers buffered samples to a host computer. In an instrumentation product, firmware can implement device-specific protocols and data formats while preserving full-speed and high-speed USB connectivity. Designers should select external flash and passive components according to the manufacturer's reference circuit, preserve the required USB impedance-controlled layout, and provide correct power, clock, reset, and decoupling arrangements. Firmware planning must also account for endpoint RAM allocation, setup packet handling, and host compatibility. The 100-pin package requires a corresponding 100-pin PCB footprint and careful escape routing around all perimeter leads.

CY7C68013A-128AXC 128-Pin USB 2.0 Controller | Infineon

The Infineon Technologies CY7C68013A-128AXC is an EZ-USB FX2LP USB 2.0 peripheral controller and ROMless 8051 microcontroller with a 24 MHz clock, 16 KB of RAM, 40 GPIOs, and a 128-pin TQFP package. It is designed for non-battery-powered USB peripheral equipment requiring high-speed USB connectivity, parallel data-transfer control, and programmable device-side firmware. An EZ-USB FX2LP is a highly integrated USB 2.0 microcontroller. It combines an 8051-compatible processing core, USB device-controller hardware, on-chip RAM, serial interfaces, and programmable general-purpose I/O in one device. Its position in the electronics hierarchy is USB interface controller → USB 2.0 peripheral controller → embedded microcontroller → semiconductor, placing it between a host computer and a USB-connected data-acquisition or control peripheral. The principal specifications are a 24 MHz operating clock, 16 KB of RAM, and 40 GPIOs in a 128-pin TQFP package. The device operates from a 3.0 V to 3.6 V supply, uses an 8-bit processor architecture, and provides serial debug support. These characteristics make it appropriate for instruments, adapters, test equipment, and embedded peripherals that need local control logic and a direct USB 2.0 interface rather than a separate host-side USB bridge. The FX2LP architecture is intended to handle USB protocol transactions while the 8051 core manages endpoint behavior, buffers, control requests, and application-specific data movement. The 16 KB RAM provides working memory for firmware and descriptors, while 40 GPIOs expose digital control and status signals to external circuitry. Serial debug supports firmware development and troubleshooting, reducing the need for additional diagnostic interfaces when the board design permits. Typical applications include high-speed USB oscilloscope and logic-analyzer front ends, test-and-measurement adapters, data-acquisition equipment, printer or scanner interfaces, industrial control adapters, and USB-to-parallel data bridges. The 40 available GPIOs are especially useful for status LEDs, control strobes, handshake signals, and discrete front-end controls. Its integrated USB controller can simplify system architecture by consolidating peripheral control and USB communication. When designing around the CY7C68013A-128AXC, verify the complete pin assignment, USB transceiver requirements, clocking arrangement, and external memory interfaces in the manufacturer datasheet before layout. A 128-pin TQFP package demands careful fanout and decoupling, while USB signal routing requires short, controlled impedance paths. Firmware must also be developed for the ROMless architecture and programmed into the target system through the supported configuration path. This page provides a design-focused overview of the 24 MHz clock, 16 KB RAM, 40 GPIO resources, 3.0 V to 3.6 V supply range, and TQFP-128 package. It also identifies same-package replacement candidates, application-fit guidance, comparison parameters, and practical PCB considerations that help engineers evaluate the controller before committing a new USB peripheral design.
