An EZ-USB FX2LP microcontroller is an application-specific USB controller in the broader hierarchy of 8051 microcontrollers, embedded processors, and USB interface integrated circuits. It combines a USB 2.0-compatible transceiver and serial-interface engine with an internal enhanced 8051 core. This integration allows one device to manage endpoint buffering, USB transfers, and peripheral data movement without relying on a separate USB transceiver.
Verified listings identify the CY7C68016A-56LFXC as a ROMless 8-bit EZ-USB FX2LP device with USB, I2C, and USART interfaces. Its operating supply range is 3 V to 3.6 V, and its listed operating temperature range is 0 °C to 70 °C. The USB 2.0 implementation is USB-IF high-speed certified under TID 40440111. Its SMD package is a 56-pin VFQFN with an exposed pad and is supplied in a tube according to the verified distributor data.
The controller’s integrated architecture reduces USB-interface component count by combining the transceiver, smart SIE, and enhanced 8051 processor in one package. Firmware controls endpoint configuration and data transfer behavior, while the processor handles application-specific processing. Because the device is ROMless, the design must provide a suitable firmware-programming and boot solution, and developers must budget memory appropriately for USB descriptors, endpoint logic, and application code.
Typical uses include high-speed USB data acquisition, USB-to-serial and USB-to-parallel adapters, test and measurement equipment, data-logging systems, industrial peripherals, and consumer USB accessories. The 56-VFQFN exposed-pad package also requires careful PCB layout and thermal management so heat can transfer through its exposed pad while preserving high-speed USB signal integrity.
A primary design consideration is the 3.0 V to 3.6 V supply constraint: the part cannot be connected directly to a 5 V USB VBUS rail without an appropriately designed power path. Layout should follow the manufacturer’s pin, differential-routing, decoupling, and exposed-pad guidance, while production firmware and connector behavior should be validated against the complete USB design.
This page consolidates verified distributor specifications, package information, lifecycle-oriented cross-reference results, and practical replacement guidance that is not presented as a single-source manufacturer summary. It also distinguishes true same-footprint drop-in candidates from broader USB-controller alternatives that require firmware or hardware changes.

典型應用
CY7C68016A-56LFXC 適用於 6 應用s: High-Speed USB Data Acquisition, USB-to-Serial and USB-to-Parallel Adapters, USB Test and Measurement Equipment, Industrial USB Data Loggers, USB Connected Consumer Peripherals, Portable Diagnostic and Monitoring Devices.
High-Speed USB Data Acquisition
The CY7C68016A-56LFXC fits high-speed USB data-acquisition front ends because its integrated USB 2.0 transceiver and smart SIE can transfer sampled data without a separate USB interface controller. Its enhanced 8-bit 8051 processor can coordinate buffering and control functions, while the 3 V to 3.6 V operating range provides a defined low-voltage design target. The implementation still depends on external program memory, carefully sized endpoint buffers, and short controlled-routing paths between the USB transceiver and connector. Firmware must configure endpoints for the expected traffic pattern, and the finished design should be checked for enumeration reliability and sustained-transfer throughput.
推薦
USB-to-Serial and USB-to-Parallel Adapters
The CY7C68016A-56LFXC is appropriate for USB-to-serial and USB-to-parallel adapters because it combines an enhanced 8051 core with USB, I2C, and USART interfaces in one controller. Firmware can translate USB commands into peripheral transactions while the integrated smart SIE handles USB protocol activity. Its 56-VFQFN exposed-pad package supports compact adapter designs, although exposed-pad soldering and copper thermal design require care. A production design should validate logic levels, driver capability, connector protection, and firmware compatibility with the host operating system before volume use.
推薦
USB Test and Measurement Equipment
The CY7C68016A-56LFXC can serve as the USB control and transfer engine in compact test and measurement equipment. Its high-speed USB certification and integrated transceiver support efficient connection to a PC, while the 8051 processor manages commands and instrument-state logic. The 3.0 V to 3.6 V supply constraint means the instrument board must include a suitable 3.3 V rail, and the ROMless architecture requires a deterministic firmware-loading method. Signal-chain isolation, measurement grounding, and USB return-path design remain separate system-level concerns that should not be inferred from the controller specifications alone.
推薦
Industrial USB Data Loggers
The CY7C68016A-56LFXC is suitable for industrial USB data loggers that move sensor or machine-event records to a host computer. The integrated USB 2.0 interface reduces external interface-component count, while the enhanced 8051 core can perform buffering, timestamping, and command handling. Because the verified operating-temperature range is 0 °C to 70 °C, the logger enclosure and internal thermal conditions must remain within that range or require a different qualified device. Firmware should include write-safe storage procedures, recovery logic, and endpoint bandwidth management to avoid data loss during host-side transfers.
推薦
USB Connected Consumer Peripherals
The CY7C68016A-56LFXC can support USB connected consumer peripherals that require a compact high-speed interface and modest local processing. Its ROMless EZ-USB architecture allows product-specific USB descriptors and endpoint behavior to be programmed rather than fixed in internal mask ROM. The 56-VFQFN exposed-pad package can save board area, but assembly yield and reworkability must be considered carefully. A finished peripheral should also implement USB-compliant power management, validated connector protection, stable firmware updates, and host compatibility testing across the intended operating systems.
推薦
Portable Diagnostic and Monitoring Devices
The CY7C68016A-56LFXC is applicable to portable diagnostic or monitoring devices that use a USB cable for configuration, data transfer, and firmware updates. Its high-speed USB interface can shorten transfer time, while the 8051 processor executes device-control logic and the smart SIE manages low-level USB traffic. The 56-VFQFN package favors compact boards, although exposed-pad soldering requires qualified assembly capability. Designers should keep the device within its 3.0 V to 3.6 V supply range and verify battery or USB-derived supply tolerances during transient, suspend, and resume testing.

設計說明
Place the USB differential pair as a controlled-impedance route directly between the CY7C68016A-56LFXC and the USB connector. The supplied data does not include the manufacturer’s trace geometry, so the exact impedance, length, and spacing values must be taken from the datasheet and USB layout guidance rather than estimated. Keep the route free of stubs and ground-plane discontinuities, and place termination and ESD-protection components in accordance with the reference circuit.
The 56-pin VFQFN has an exposed pad that must be soldered and connected to the PCB ground plane for electrical and thermal performance. Follow the datasheet’s exposed-pad dimensions and land pattern rather than approximating them from the package name. Provide uninterrupted copper where layout rules permit, use an appropriate solder-mask strategy, and evaluate the actual junction temperature against the verified 0 °C to 70 °C operating range.
The CY7C68016A-56LFXC accepts only a 3.0 V to 3.6 V operating supply. Do not connect its core supply directly to 5 V USB VBUS. Design the power path to account for USB attach and detach, inrush, cable transients, and the voltage required by the local 3.3 V system. Place required bypass capacitors close to their supply and ground pins and validate the rail during suspend, resume, and bus-power transitions.
Do not treat a shared package and EZ-USB family name as proof that every firmware image works unchanged on a different FX2LP member. Before substituting CY7C68015A, CY7C68013A, or a related suffix variant, compare GPIO assignments, endpoint use, timer resources, boot behavior, register differences, and the exposed-pad footprint. Program and test the replacement with the production firmware and intended host software rather than relying on enumeration alone.
合規資訊
The supplied verified snippets do not provide an explicit RoHS, REACH, lead-free, halogen-free, or conflict-minerals statement for this exact MPN. AEC-Q100 status is treated as not applicable because this is an industrial USB microcontroller rather than an identified automotive-qualified variant.
