CY7C68013A-128AXI - 48MHz USB 2.0 Controller | Infineon
N.º da peça: CY7C68013A-128AXI ✓ AtivoCY7C68013A-128AXI Visão geral
An EZ-USB FX2LP is a specialized USB microcontroller within the broader hierarchy of microcontrollers, USB peripheral controllers, interface ICs, and semiconductors. Unlike a conventional general-purpose MCU, the device integrates a USB 2.0 transceiver, programmable GPIF interface logic, and an 8051 processor into one integrated circuit. This architecture lets designers implement high-speed USB peripherals without relying on a discrete USB transceiver.
Three headline capabilities define the CY7C68013A-128AXI: a 48 MHz 8051 core, a maximum USB 2.0 bandwidth above 53 MB/s, and 40 general-purpose I/O pins. The 16 KB internal RAM supports USB descriptor and endpoint configuration, while the serial debug interface assists firmware development and troubleshooting. Its integrated USB 2.0 transceiver also reduces external circuitry compared with solutions using a separate controller and transceiver.
The FX2LP architecture uses a General Programmable Interface, or GPIF, to connect the USB controller to external FIFOs, processors, or peripherals. This programmable interface is central to high-speed data movement because it coordinates read and write timing without requiring every connected device to implement a complete USB stack. The 8051 processor remains responsible for initialization, control transfers, descriptor handling, and application-specific firmware.
Typical uses include USB-to-FIFO data acquisition, industrial data loggers, oscilloscopes and logic analyzers, test equipment, custom USB bridges, and high-throughput peripheral adapters. Its 40 GPIOs can support control signals, status indicators, triggers, and chip selects. The 128-pin TQFP provides substantially more interface connectivity than small USB controller packages, making it suitable for designs that need both high-speed data transfer and extensive control logic.
PCB design should preserve short, impedance-controlled USB differential traces and provide the decoupling and layout specified by the manufacturer datasheet. The numerous external pins also require careful fan-out between the fine-pitch TQFP and surrounding circuitry. Firmware development should account for the device's role as a USB bus master and use its serial debug facilities to validate enumeration before testing sustained high-speed transfers.

Aplicações típicas
CY7C68013A-128AXI é adequado para 6 aplicaçãos: USB Logic Analyzer, Industrial USB Data Acquisition, USB-to-FIFO Bridge, Oscilloscope and Test Instrument, USB Protocol Analyzer, Custom USB Data Acquisition Adapter.
USB Logic Analyzer
The CY7C68013A-128AXI fits a USB-connected logic analyzer because its 48 MHz 8051 core controls enumeration while the GPIF transfers captured samples from external acquisition hardware. Its 40 GPIOs can provide capture triggers, arm signals, channel-enable controls, and status indicators. The integrated USB 2.0 transceiver supports transfer rates above 53 MB/s, allowing sampled data to reach a host efficiently. A practical implementation should define USB descriptors in firmware, use contiguous FIFO addressing for predictable timing, and validate enumeration before enabling high-speed acquisition.
Recomendado
Industrial USB Data Acquisition
The CY7C68013A-128AXI is suitable for industrial USB data acquisition because it combines USB 2.0 high-speed transfer, a programmable GPIF interface, and 40 general-purpose I/O lines. External ADC, sensor, or FPGA peripherals can connect through parallel GPIF signals while the 8051 core handles descriptors, configuration, and control transfers. The 48 MHz processor supports responsive protocol management, and the integrated USB transceiver reduces board complexity. Production designs must confirm the exact temperature grade and validate conducted and radiated emissions for the finished equipment.
Recomendado
USB-to-FIFO Bridge
The CY7C68013A-128AXI can implement a high-throughput USB-to-FIFO bridge by using GPIF as the hardware-assisted interface between USB endpoints and an external asynchronous FIFO. Its USB 2.0 architecture supports data rates above 53 MB/s, while the 8051 core initializes endpoints, executes the control request state machine, and monitors transfers. Forty GPIOs provide sideband control for FIFO read/write strobes, occupancy flags, resets, and diagnostics. Timing must be checked against both the FX2LP clock requirements and the external FIFO interface specifications.
Recomendado
Oscilloscope and Test Instrument
The CY7C68013A-128AXI fits oscilloscope and test-instrument peripherals that move large sample volumes to a USB host. The 48 MHz embedded processor manages enumeration and control requests, the integrated transceiver supports high-speed USB, and GPIF can transfer bursts from acquisition FIFOs with minimal software involvement. The 40 GPIOs support trigger routing, range controls, status LEDs, and instrument interlocks. For accurate measurements, separate analog acquisition paths from digital control signals and verify timing margins across every supported USB host and transfer configuration.
Recomendado
USB Protocol Analyzer
The CY7C68013A-128AXI is appropriate for a USB protocol-analysis accessory that must observe traffic while presenting a fast data path to a host processor. Its GPIF provides a programmable connection to external capture memory, while the 8051 core can handle peripheral configuration and control requests. Forty GPIOs are useful for trigger inputs, capture enables, status reporting, and synchronization signals. The design should include independent clocking or carefully synchronized clock domains and should account for USB packet fragmentation when sizing capture memory and host bandwidth.
Recomendado
Custom USB Data Acquisition Adapter
The CY7C68013A-128AXI provides a compact platform for a custom USB adapter that bridges external sensors, converters, or industrial peripherals to a computer. Its integrated 8051 controller, 16 KB RAM, and 40 GPIOs support local control and direct acquisition logic, while USB high-speed operation supports efficient transfer of larger records. GPIF timing can be configured for compatible external devices, reducing software involvement during bulk transfers. Firmware must handle enumeration, retries, stalls, and unexpected USB suspend events for dependable field operation.

Notas de projeto
Route USB D+ and D- as a short, continuous 90-ohm differential pair from the controller to the USB connector or upstream transceiver. Avoid stubs, test pads, and plane changes beneath the pair, and provide a continuous ground reference. Place required decoupling close to the supply and ground pins. The 128-pin TQFP also requires deliberate fan-out because its fine-pitch pitch can make escape routing difficult without careful layer planning.
Separate the 48 MHz clock network from high-speed USB, high-current switching stages, and sensitive analog acquisition inputs. Use the manufacturer clock and decoupling recommendations to control jitter, crosstalk, and ground bounce. Because the controller coordinates USB transfers through GPIF timing, any clock or reset disturbance can affect endpoint scheduling as well as data integrity. Validate timing with an oscilloscope or protocol analyzer after final assembly.
Do not treat the 56-pin and 128-pin FX2LP variants as direct substitutions. The smaller package may omit address-bus or other controller signals required by the 128-pin design. Similarly, confirm that a proposed CY7C68013 or CY7C68013A suffix has the same clock speed, GPIO mapping, temperature range, and lifecycle status. Review the exact manufacturer ordering table and pin descriptions before releasing a replacement to production.
Budget the USB transceiver, 8051 core, and attached GPIF logic together when planning the 3 V to 3.6 V supply. Keep regulator output impedance and local capacitance compatible with the datasheet requirements, especially during high-speed transmit bursts. Place bulk and high-frequency decoupling near the relevant supply pins and maintain low-impedance ground returns. Confirm that downstream loads and external devices do not pull the I/O or supply rails outside their permitted limits.
