CY7C68016A-56LTXC - USB 2.0 Controller | Infineon
Référence : CY7C68016A-56LTXC ✓ ActifCY7C68016A-56LTXC Présentation
An EZ-USB FX2LP controller is an application-specific USB microcontroller rather than a general-purpose MCU. Its internal 8051-compatible processing engine, USB interface, and programmable I/O architecture allow a single device to implement peripheral functions directly in USB firmware. In the broader hierarchy, the part is a USB interface controller, interface IC, embedded microcontroller, and semiconductor used to bridge USB connectivity with external data acquisition, control, or communication circuitry.
The CY7C68016A-56LTXC combines a 24 MHz operating clock with a 3 V to 3.6 V supply range and 40 I/O ports. Its ROMless architecture directs firmware into external memory, allowing application-specific code to define enumeration, data transfer protocols, and peripheral behavior. USB 2.0 high-speed support provides a practical bandwidth advantage over full-speed-only designs when the host, cable, firmware, and peripheral implementation support the required transfer rate.
The exposed-pad 56-VFQFN package supports compact surface-mount layouts while providing a thermal and electrical connection to the PCB through its exposed pad. The 56-pin arrangement supports the USB signals, 8051 core functions, external program and data memory interfaces, general-purpose I/O, clock, reset, and power connections. Because this is a ROMless embedded controller, designers must also provide the required external memory and ensure firmware timing, memory addressing, and USB endpoint configuration are compatible with the target system.
Typical applications include high-speed USB test equipment, oscilloscope and logic-analyzer interfaces, industrial measurement modules, USB-to-serial bridges, data loggers, scanners, laboratory instruments, and embedded host adapters. The 40 available I/O ports are especially useful when an application requires multiple discrete controls, status indicators, data buses, or peripheral select signals in addition to the USB interface.
PCB implementation should follow the Infineon pin and layout guidance for the 56-VFQFN exposed-pad package. Keep USB differential routing short, impedance controlled, and continuous, and provide the specified input and bypass capacitors near their associated pins. Route high-speed or sensitive signals away from the exposed pad connection where practical, and make adequate provision for thermal dissipation through the package pad and surrounding copper.
This product page combines the exact published device characteristics, application-oriented guidance, comparison criteria, and practical design notes needed to evaluate the CY7C68016A-56LTXC. Review the complete pin description, electrical limits, memory interface, USB timing, and exposed-pad layout instructions in the manufacturer datasheet before schematic sign-off or PCB release.

Applications typiques
CY7C68016A-56LTXC convient pour 6 applications: High-Speed USB Test Equipment, Industrial Data Acquisition Module, USB-to-Serial Protocol Bridge, Laboratory Instrument Interface, USB Data Logger, Security and Access-Control Peripheral.
High-Speed USB Test Equipment
The CY7C68016A-56LTXC fits high-speed USB test equipment that requires a programmable peripheral controller and substantial parallel I/O. Its USB 2.0 full-speed and high-speed classification supports faster data movement than a full-speed-only design, while the 40 I/O ports can operate acquisition, trigger, status, and fixture-control signals. The ROMless 8051-compatible architecture allows instrument-specific commands and data formats to be implemented in external program memory. In practice, the USB host, firmware, cable, and acquisition engine must all sustain the intended transfer rate, and the PCB must preserve controlled USB signal integrity.
Recommandé
Industrial Data Acquisition Module
The CY7C68016A-56LTXC is suitable for an industrial data-acquisition module that combines a USB host connection with multiple sensors, actuators, or status lines. The 40 I/O ports offer more parallel control than a basic USB bridge, and the 24 MHz 8051-compatible processor can manage acquisition sequencing and protocol handling in external memory. Using USB 2.0 high-speed operation can shorten transfer time for larger sample sets. Industrial implementations should add isolation, surge protection, and power conditioning appropriate to the connected equipment while observing the controller's 3 V to 3.6 V supply limits.
Recommandé
USB-to-Serial Protocol Bridge
The CY7C68016A-56LTXC can implement a customized USB-to-serial bridge when a fixed-interface USB converter cannot support the required framing, handshaking, or device-specific behavior. Its ROMless architecture permits firmware-defined command handling, while the 8051-compatible core and external memory interface support application logic beyond a simple pass-through path. The 40 I/O ports can provide handshake, direction, reset, and fault signals around the serial transceiver. USB 2.0 high-speed capability is useful when the protocol carries substantial traffic, although the final throughput remains limited by the attached UART or other serial interface.
Recommandé
Laboratory Instrument Interface
The CY7C68016A-56LTXC suits laboratory instruments that need a USB control endpoint and custom parallel data acquisition, including analyzers, programmable sources, and automated measurement fixtures. The controller's 24 MHz clock supports firmware-driven command parsing and sequencing, and its 40 I/O ports reduce the need for separate GPIO expanders. USB 2.0 high-speed operation can improve transfer throughput when instrument data is burst-oriented. Designers should define the control and data endpoints carefully, reserve bus resources for debugging, and use controlled impedance routing because reliable enumeration and sustained transfer depend on signal integrity as well as protocol design.
Recommandé
USB Data Logger
The CY7C68016A-56LTXC is well matched to a compact USB data logger that records sensor or event information and transfers it to a host computer. Its 40 I/O ports can support digital sensors, alarm lines, storage-control signals, and status indicators, while external program and data memory allows application-specific buffering. USB 2.0 operation supports efficient transfer after an acquisition session, and high-speed mode can reduce transfer time for large files. The logger design must account for storage latency, buffering strategy, bus-powered current limits, and reliable firmware recovery rather than treating USB enumeration as the complete storage solution.
Recommandé
Security and Access-Control Peripheral
The CY7C68016A-56LTXC can serve as the USB-facing controller in a security, access-control, or credential-reader peripheral that requires a custom command set and several discrete signals. USB 2.0 provides a standard host interface, while the 40 I/O ports can manage indicators, interlocks, request lines, and peripheral enables. ROMless execution permits the device's behavior and security-related protocol logic to be updated through external firmware. Production designs should protect firmware access, validate commands, define safe states for power loss, and isolate external I/O where a reader or actuator can introduce electrical faults.

Notes de conception
Route the USB differential pair as a controlled-impedance pair with minimal stubs, vias, and branch lengths. Keep the USB PHY connection short and follow the Infineon reference layout for connector, series-resistance, and capacitor placement. Although the controller is ROMless, the USB interface remains sensitive to return-path discontinuities and impedance mismatches. Separate the pair from clocks, memory buses, and switching-power supply nodes to reduce susceptibility to deterministic and radiated interference.
Preserve the manufacturer-defined exposed-pad land pattern and the associated ground or thermal structure for the 56-VFQFN package. Place input and bypass capacitors at the pins they serve, with short ground paths through the nearest reference plane. Because external memory is required, maintain the published address, data, and control timing while keeping high-speed traces short and avoiding split-plane crossings under the controller or memory devices.
Do not treat a same-package family member as an automatic substitute. Compare the complete pin-description tables, external-memory connections, GPIO multiplexing, clock requirements, reset behavior, and USB firmware assumptions before replacing the target. In particular, the CY7C68013A-56LTXC has 24 GPIOs versus 40 I/O ports on the CY7C68016A-56LTXC, so schematic and firmware changes may be necessary even when the PCB footprint matches.
Use a stable supply within the published 3 V to 3.6 V operating range and verify startup, load-transient, and USB suspend behavior on the completed board. The ROMless system adds external memory and peripheral loads whose current demand can vary with USB traffic. Place bulk and high-frequency decoupling according to the manufacturer recommendation, and confirm that exposed-pad and copper temperature rise remains acceptable at the highest expected ambient condition.
Validate USB enumeration and sustained transfer on a representative PCB rather than relying only on functional software tests. Check differential impedance, common-mode behavior, clock integrity, external-memory timing, and connector return paths using appropriate test equipment. Firmware should also exercise enumeration after warm reset, power cycling, suspend, and resume because protocol compliance and physical signal quality are separate requirements for a reliable USB peripheral.
