CY7C68014A-56PVXC - 16K RAM USB 2.0 Controller | Infineon
MPN: CY7C68014A-56PVXC ✓ Hoạt độngCY7C68014A-56PVXC Tóm tắt
An EZ-USB FX2LP USB 2.0 peripheral controller is a specialized USB interface microcontroller rather than a general-purpose processor. It combines an 8051-compatible core with USB peripheral functions and programmable I/O, placing USB connectivity, control logic, and application-specific interfaces in one device. This hierarchy runs from USB 2.0 peripheral controller to application-specific microcontroller, interface controller, and integrated circuit.
The controller uses 16K RAM for firmware and data buffering, while its ROMless architecture allows the application firmware to be loaded after reset. The 24 GPIOs support digital status inputs, control outputs, and peripheral signals. A 3 V to 3.6 V operating supply supports integration with 3.3 V systems, and the 8-bit data bus enables connection to external memory or application circuitry where required.
The FX2LP architecture is intended for USB peripherals that require more application-specific control than a basic USB interface bridge. Its integrated USB 2.0 peripheral functionality reduces the need for a separate USB controller in suitable designs. The processor clock listed for this device is 24 MHz, providing a defined timing basis for USB enumeration, endpoint handling, data movement, and firmware execution.
Typical uses include USB-connected test and measurement instruments, data-acquisition peripherals, industrial control interfaces, programming equipment, storage adapters, and compact human-interface devices. The 24 GPIOs are particularly useful when a design needs configurable control or monitoring signals in addition to USB communication. Battery-powered equipment is also an application focus for the low-power FX2LP family.
Board design should follow the manufacturer pin-description table and recommended USB circuit layout. Keep high-speed USB traces short and controlled, provide the required 1.5-kohm pull-up behavior on the USB D+ line, and place bypass capacitance close to the supply pins. Confirm all signal levels, external memory connections, and programming connections against the device documentation before releasing the PCB.
This product record combines the manufacturer identification, interface characteristics, package information, lifecycle status, and design-focused guidance in a format useful for engineering selection and sourcing. It also distinguishes verified drop-in alternatives from functionally similar controllers so that PCB compatibility can be evaluated before a component substitution is approved.

Ứng dụng tiêu biểu
CY7C68014A-56PVXC phù hợp cho 6 Áp dụngs: USB Data-Acquisition Peripherals, Battery-Powered USB Instruments, Industrial USB Control Interfaces, USB-to-Serial Protocol Adapters, USB Flash-Drive Controller, Programmable USB Test Equipment.
USB Data-Acquisition Peripherals
The CY7C68014A-56PVXC fits compact USB data-acquisition equipment because it combines a 24 MHz 8051 core, 16K RAM, 24 GPIOs, and USB 2.0 peripheral control in one 56-pin BSSOP device. Its configurable I/O can handle trigger, status, range, and enable signals while the integrated USB function manages enumeration and data transfer. The 3 V to 3.6 V supply range also aligns with 3.3 V acquisition systems. Designers should allocate the GPIOs for acquisition control, validate USB endpoint bandwidth against the intended transfer rate, and use the manufacturer pin table when routing external analog-control and digital interfaces.

Battery-Powered USB Instruments
The low-power FX2LP architecture makes the CY7C68014A-56PVXC relevant to battery-powered USB instruments where a 56-pin BSSOP and 24 MHz 8051 core provide control without a separate USB controller. The Infineon product page specifically identifies battery-powered applications, while 24 GPIOs can operate mode switches, status indicators, and measurement-enable signals. The 3 V to 3.6 V operating range supports direct integration into suitable 3.3 V portable systems. Final selection should compare sleep-mode current, active power, USB suspend behavior, and battery capacity against the complete instrument power budget.
Được đề xuất
Industrial USB Control Interfaces
The CY7C68014A-56PVXC can form the USB-facing controller in industrial equipment requiring a compact, application-specific interface. Its 8051 processor runs application firmware from the 16K RAM, while 24 GPIOs support isolated or non-isolated control signals, relays, indicators, and machine-state inputs. USB 2.0 provides a standard host connection for configuration and diagnostics. Layouts should provide clean USB routing, local supply decoupling, robust grounding, and appropriate logic-level interfacing so industrial wiring does not expose the controller to excessive ESD or surge energy.
Được đề xuất
USB-to-Serial Protocol Adapters
For USB-to-serial protocol adapters, the CY7C68014A-56PVXC provides a dedicated USB device controller with 16K RAM and 24 GPIOs for bridging commands and status signals. Application firmware can implement a protocol translator without an external processor, while the 8051 core handles endpoint activity and data formatting. The device's 8-bit data bus and 24 MHz clock provide resources for external logic where required. Engineers should partition USB and serial interrupt latency, verify buffer depth against the protocol's worst-case burst, and test enumeration across the intended host operating systems.
Được đề xuất
USB Flash-Drive Controller
The ROMless CY7C68014A-56PVXC can serve as the controller in a USB storage peripheral because it integrates USB 2.0 device handling, a 24 MHz 8051 core, 16K RAM, and configurable I/O. Firmware can manage enumeration, command processing, storage-status signaling, and data movement through an appropriate external memory interface. The 56-pin BSSOP package permits a compact implementation, although actual board area will be dominated by flash and passives. Validate protocol compatibility, sustained transfer behavior, write-protection logic, and USB bus-power requirements before production.
Được đề xuất
Programmable USB Test Equipment
The CY7C68014A-56PVXC is appropriate for programmable USB test and measurement front ends that need local control, data buffering, and configurable digital stimulus. The 16K RAM can hold compact firmware and working data, while 24 GPIOs can drive test enables, fixture controls, and status indicators. USB 2.0 provides a familiar connection to a PC for automated stimulus sequencing and result transfer. For bench instruments, preserve analog and sensitive digital separation, route high-speed USB as a controlled 90-ohm differential pair, and verify timing between enumeration requests and external test-fixture actions.

Ghi chú thiết kế
Route the USB D+ and D- pair as a short, continuous 90-ohm differential pair with symmetric geometry and a continuous ground reference. Avoid stubs, test pads, and unnecessary layer transitions because the CY7C68014A-56PVXC implements USB 2.0 peripheral signaling at high data rates. Follow the manufacturer's USB layout guidance and place the specified 1.5-kohm pull-up resistor on D+ at the appropriate device-side location. Confirm the final arrangement against the current manufacturer reference design.
Place all 3.3 V bypass capacitors close to the supply and ground pins, with the shortest possible return path. The stated operating range is 3 V to 3.6 V, so do not allow USB bus-powered system transients or local regulator ripple to push the rail outside the device limits. Separate sensitive analog or signal-conditioning circuitry from the switching and digital return paths, and use the manufacturer power-supply connection and decoupling recommendations for the final board.
Treat the CY7C68014A-56PVXC as a ROMless controller and ensure the firmware-loading and reset path is designed correctly for the production system. A failure to support enumeration or load firmware can appear as an unusable USB device even when the controller itself is functioning. Review clock start-up, reset, firmware download, and USB attach timing against the manufacturer application information, and test cold-start and host-removal behavior before release.
Use the manufacturer package drawing and pin-description table for all 56 terminal assignments. The generic package representation on this page does not include a matching 56-pin BSSOP drawing, so do not use a generic 56-pin outline as the authority for pad geometry, pin-one location, or exposed features. Confirm land pattern, paste, courtyard, solder profile, and assembly orientation against the current package drawing before releasing the PCB files.
