CY7C68003-20FNXIT Full-Speed USB 2.0 Transceiver | Infineon
MPN: CY7C68003-20FNXIT ✓ Hoạt độngCY7C68003-20FNXIT Tóm tắt
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.

Ứng dụng tiêu biểu
CY7C68003-20FNXIT phù hợp cho 6 Áp dụngs: Portable Data Collection Terminals, USB Configuration and Debug Ports, Personal Computer Peripherals, Embedded USB-to-Serial Adapters, Smart Home and Sensor Hubs, Instrumentation and Test Equipment.
Portable Data Collection Terminals
The CY7C68003-20FNXIT suits a portable data collector that needs one full-speed USB connection for synchronization, charging integration, or configuration transfer. Its single-transceiver architecture avoids the board area required by a multi-port interface array, while the 2.14 mm by 1.76 mm WLCSP package can be placed close to a board-edge connector. The host or device protocol must remain in the companion controller. Short data routing and continuous grounding are essential because a compact WLCSP layout leaves limited room for correcting long-trace effects.

USB Configuration and Debug Ports
A configuration port on an industrial controller can use the CY7C68003-20FNXIT when the design requires one full-speed USB physical interface and limited board area. The transceiver reduces the connector-side component count compared with a discrete USB signaling implementation, provided the host controller already contains the required USB protocol engine. Place the device near the connector and separate the USB data region from switching power stages to reduce susceptibility to common-mode noise. Validate enumeration behavior after every layout revision.
Được đề xuất
Personal Computer Peripherals
Compact PC accessories can adopt the CY7C68003-20FNXIT for a single full-speed USB interface used for control, data transfer, or firmware updates. Its 20-ball WLCSP footprint supports dense two-sided layouts where connector clearance is limited. The USB controller must support the intended device class and operating speed, since the transceiver provides the physical interface rather than the complete protocol stack. Designers should also check the manufacturer requirements for USB data routing, supply bypass placement, and exposed connector protection.

Embedded USB-to-Serial Adapters
The CY7C68003-20FNXIT can support the physical USB side of a compact embedded adapter that bridges USB to another internal interface. The controller handles enumeration and data translation, while the MoBL USB transceiver manages the USB physical signaling. The small WLCSP package is valuable in adapter designs where the connector and protection components already consume most available board area. Confirm the exact USB speed, supply rails, and pin functions in the manufacturer documentation before finalizing the adapter schematic.

Smart Home and Sensor Hubs
A smart-home or sensor hub may use the CY7C68003-20FNXIT for one full-speed USB management connection to a host computer or service interface. Its small package preserves PCB area for radio, sensing, or power-management circuitry. Because the IC is a physical transceiver rather than a USB host controller, the design must pair it with a compatible USB-capable processor. Keep the interface section away from switching regulators and follow the manufacturer reference layout to reduce radiated emissions and improve reliability.
Được đề xuất
Instrumentation and Test Equipment
Compact instrumentation equipment can use the CY7C68003-20FNXIT for a single USB control or data port. The 20-ball WLCSP package allows the interface section to be placed near a panel connector without consuming a large section of the board. A suitable USB controller must provide device or host functionality, and the overall system must meet the required data rate without introducing timing margin problems. Use controlled routing, continuous ground planes, and connector-side protection compatible with the manufacturer recommendations.

Ghi chú thiết kế
Place the CY7C68003-20FNXIT close to the USB connector and route the two USB data nets on a continuous layer with a stable ground reference. Avoid branches, long stubs, and unnecessary test pads because they interrupt the controlled-impedance path. Keep the USB region clear of switching-node copper and high-current return paths, while maintaining the ground plane beneath the data traces.
Follow the manufacturer package drawing and recommended land pattern for the 20-ball WLCSP before releasing artwork. Confirm ball assignments, exposed thermal or ground requirements, solder-mask clearances, and assembly tolerances against the latest package documentation. A footprint that resembles another fine-pitch WLCSP should not be reused unless every ball position and courtyard has been checked.
Install the manufacturer-recommended bypass capacitance as close as practical to the supply and ground balls, and verify the selected capacitors for effective capacitance under DC bias. USB traffic can create fast current transitions, so the supply return path should be short and decoupled. Confirm the operating current and voltage limits in the manufacturer datasheet against the system power budget.
Do not treat the CY7C68003-20FNXIT as a complete USB controller. It supplies one physical full-speed transceiver, while device enumeration, descriptors, power states, and transfer handling depend on the companion controller and firmware. Also do not assume a similarly named USB transceiver is pin-compatible: compare supply voltage, control pins, data timing, and package ball assignments.
