CY7C68015A-56PVXC - Low-Power USB 2.0 Controller | Infineon
料号： CY7C68015A-56PVXC ✓ 量产中CY7C68015A-56PVXC 概述
An EZ-USB FX2LP controller is a USB interface IC and an application-specific microcontroller. It belongs to the broader hierarchy of interface ICs, USB controllers, peripheral controllers, embedded microcontrollers, and semiconductors. Unlike a conventional fixed-function USB transceiver, the FX2LP architecture can divide USB traffic among multiple endpoint buffers, support control, bulk, and interrupt transfers, and connect external parallel data buses to the USB host through a deterministic, firmware-controlled protocol.
The CY7C68015A is positioned as the low-power member of the EZ-USB family, with additional GPIO and communication features intended for non-battery-powered applications. USB 2.0 high-speed operation, internal endpoint buffering, and programmable firmware make the controller suitable for data acquisition systems, test equipment, industrial peripherals, communications equipment, and custom USB bridges. The 56-pin SSOP package provides a practical option for compact board designs requiring a high pin count and external peripheral connectivity.
Engineering designs should pay close attention to USB signal routing, crystal and clock requirements, supply decoupling, firmware initialization, and endpoint memory allocation. The SSOP footprint has fine lead pitch and requires a careful PCB layout with short differential USB traces, continuous reference planes, and minimized stub lengths. Power sequencing, ground-plane continuity, and proper crystal loading are equally important for reliable enumeration across multiple host environments.
This product page combines manufacturer-oriented device information, distributor listings, family cross-reference results, and application-specific engineering guidance. It emphasizes the role of the CY7C68015A-56PVXC as a configurable USB 2.0 peripheral controller rather than presenting the device merely as a generic interface IC. Buyers should compare the exact package suffix, firmware compatibility, electrical requirements, and USB behavior of any replacement before committing to a drop-in substitution.

典型应用
CY7C68015A-56PVXC 适用于 6 应用s: High-Speed USB Data Acquisition, Industrial USB-to-Parallel Bridge, USB Test and Measurement Instrument, Custom USB Communications Adapter, USB-Controlled LED and Lighting System, Portable USB Diagnostic Device.
High-Speed USB Data Acquisition
The CY7C68015A-56PVXC fits custom data-acquisition peripherals because its USB 2.0 high-speed controller and programmable endpoint architecture can transfer samples or control data between a host and an external acquisition engine. The embedded 8051-compatible core handles enumeration, endpoint control, and protocol sequencing, while the 24 GPIO support status signals, triggers, and supervisory functions. Designers should size endpoint buffers according to the acquisition format and measure the actual throughput with the intended firmware, since protocol overhead and external bus timing determine usable bandwidth. Differential USB routing, continuous grounding, local decoupling, and a controlled clock arrangement are essential for reliable operation across multiple USB hosts.
推荐
Industrial USB-to-Parallel Bridge
The CY7C68015A-56PVXC is suitable for industrial USB-to-parallel bridges that expose legacy acquisition, control, or machine interfaces to a modern USB host. Firmware can define the protocol, endpoint scheduling, and data framing, while the extra GPIO can carry direction, handshake, fault, and ready signals. Its 56-pin SSOP package provides access to a broad set of controller and general-purpose signals without requiring a separate USB interface IC. For factory equipment, isolate noisy motor and relay wiring from the USB domain, maintain a single uninterrupted ground reference where required, and validate suspend and resume behavior against the complete system power budget.
推荐
USB Test and Measurement Instrument
The CY7C68015A-56PVXC can implement a custom USB test or measurement peripheral when a fixed-function instrument protocol is insufficient. Its programmable endpoint behavior allows waveform data, configuration commands, and status information to be separated into appropriate USB transfers, while the embedded controller manages enumeration and device-specific firmware. The 24 GPIO can support trigger inputs, relay control, interlock signals, and front-panel status. Use a low-noise layout around the analog section even though the USB controller itself is digital, and test hot-plug, suspend, resume, and repeated enumeration across operating systems. Firmware versioning should be included in the instrument’s USB descriptor so host software can identify compatible revisions.
推荐
Custom USB Communications Adapter
The CY7C68015A-56PVXC supports custom communications adapters that need a programmable USB endpoint structure rather than a fixed virtual COM device. Firmware can implement framing, acknowledgments, device discovery, and command handling while the controller transfers data to an external communications processor or microcontroller. The extra GPIO provides ready, busy, reset, and fault signaling for the attached peripheral. For dependable host-to-device communication, specify endpoint bandwidth for both bulk and interrupt traffic, avoid relying on undocumented timing, and test behavior when the host suspends the device. The SSOP layout also warrants thermal inspection under sustained high-rate transfer workloads.
推荐
USB-Controlled LED and Lighting System
The CY7C68015A-56PVXC can act as the USB control element in programmable lighting, status-indicator, and laboratory illumination systems. Its GPIO outputs can drive enable or selection lines for external driver circuits, while firmware maintains lighting sequences, brightness commands, and device status over USB. Because the controller does not directly establish the lighting output capability, the external driver stage must be selected for the required current and voltage. Keep high-current or switching outputs physically separated from the USB and clock traces, provide local return paths, and use firmware-defined limits to prevent excessive channel activity. A configurable protocol also allows host software to update scenes without requiring a dedicated user-interface controller.
推荐
Portable USB Diagnostic Device
The CY7C68015A-56PVXC fits portable diagnostic equipment that enumerates as a custom USB peripheral and exchanges structured records with a laptop or service tablet. Low-power-oriented FX2LP variants are useful when the product spends significant time idle or operating from a limited power budget, but the complete system must still evaluate sleep current and wake behavior. Firmware can expose diagnostic results through dedicated endpoints while GPIO handles switches, indicators, and external triggers. Designers should minimize the number of always-active external loads, provide a clean USB connection path, and validate battery life under realistic idle and transfer conditions before finalizing the enclosure and cable strategy.

设计说明
Route USB D-plus and D-minus as a short, tightly coupled differential pair with a continuous reference plane and no unnecessary stubs. Place any USB-series impedance-control elements close to the controller according to the manufacturer reference design. Keep switching regulators, crystal circuitry, and high-current outputs away from these nets to minimize radiated emissions and improve enumeration reliability.
Provide local high-frequency and bulk decoupling at the controller supply pins, following the capacitance and placement requirements in the manufacturer application circuit. Confirm the device's operating and I/O voltage ranges before connecting external logic. If 3.3 V peripherals share the board, check signal-level compatibility and sequencing so no external device drives a pin before the controller supply is valid.
Use a continuous ground plane and route the crystal, its load components, and associated traces as short as practical. Avoid placing test pads or high-speed switching nodes near clock and USB nets. The 56-pin SSOP footprint also requires a narrow assembly process window, so verify pad dimensions, solder mask, paste volume, and component orientation against the current package drawing.
Do not treat a family-related MPN as an automatic replacement. Compare the exact pin descriptions, clock source, reset behavior, suspend current, endpoint resources, firmware support, and package suffix of the target and candidate. A 56-pin SSOP designation confirms the general footprint family, but it does not by itself prove identical lead finishing, temperature grade, or board-handling characteristics.
