MPN: CY7C68013A-100AXI ✗ End of LifeCY7C68013A-100AXI Overview
An EZ-USB FX2LP USB microcontroller is a specialized USB interface controller that places a configurable USB peripheral, USB transceiver, and embedded 8051 processor on one device. Within the product hierarchy, it belongs to the USB interface controller class, then microcontrollers, then integrated circuits and semiconductors. Its principal advantage over a discrete USB system interface controller is that firmware can configure endpoint behavior, packet handling, and data routing without requiring a separate external USB transceiver.
Key features include full-speed and high-speed USB 2.0 operation, 16 KB of internal RAM, 40 GPIO, an enhanced 8051 processor, and integrated USB transceiver circuitry. The controller supports multiple endpoint configurations, allowing a system to buffer data, perform local transformations, or separate streams before transferring them over USB. Its ROMless architecture leaves the final application firmware in external memory, which supports product-specific boot code, device identification, and configuration routines.
The FX2LP architecture is designed for high-throughput peripheral applications where USB bandwidth is more important than general-purpose processor integration. Its 8051 core operates at 48 MHz, while the USB engine handles the protocol and transfer functions. Up to 16 KB of internal RAM provides working space for descriptors, endpoint buffers, status variables, and firmware routines. The 100-pin TQFP package also exposes substantially more GPIO and interface signals than compact 56-pin FX2LP variants.
Typical uses include USB-to-serial adapters, logic analyzers, test and measurement equipment, data acquisition systems, custom USB peripherals, and industrial data-logging products. In a logic analyzer, the GPIO array can capture digital activity while the USB engine transfers buffered samples to a host computer. In an instrumentation product, firmware can implement device-specific protocols and data formats while preserving full-speed and high-speed USB connectivity.
Designers should select external flash and passive components according to the manufacturer's reference circuit, preserve the required USB impedance-controlled layout, and provide correct power, clock, reset, and decoupling arrangements. Firmware planning must also account for endpoint RAM allocation, setup packet handling, and host compatibility. The 100-pin package requires a corresponding 100-pin PCB footprint and careful escape routing around all perimeter leads.
This product page combines manufacturer specifications, package details, search-oriented technical questions, application guidance, and verified same-footprint alternatives. It also identifies lifecycle constraints and organizes practical USB controller design considerations that engineers can apply when planning firmware, PCB layout, and product longevity.

Typical Applications
CY7C68013A-100AXI is suitable for 6 applications: USB Logic Analyzer, High-Speed USB Data Acquisition, USB-to-Serial Bridge, Custom USB Test Equipment, Industrial USB Data Logger, USB Peripherals and dongles.
USB Logic Analyzer
The CY7C68013A-100AXI fits a USB logic analyzer because it provides 40 GPIO, a 48 MHz enhanced 8051 core, and an integrated USB 2.0 transceiver in one controller. Firmware can sample digital lines, maintain capture state in 16 KB of internal RAM, and transfer completed records to a host through programmable endpoints. The 100-pin TQFP provides more peripheral connections than the 56-pin FX2LP variants, making it useful when trigger, capture, status, and configuration signals must coexist. Designers should allocate endpoint RAM carefully, confirm acquisition timing against the GPIO layout, and follow the manufacturer reference circuit for USB routing and decoupling.
Recommended
High-Speed USB Data Acquisition
The CY7C68013A-100AXI is useful in high-speed USB data-acquisition equipment that must aggregate samples or move structured records to a host. Its FX2LP USB engine supports transfer rates above 53 MB/s, while the 48 MHz 8051 processor manages acquisition control, status reporting, and buffer administration. Sixteen kilobytes of internal RAM can hold endpoint state and working buffers, reducing pressure on external storage during short transfer bursts. A practical implementation should define endpoint descriptors early, verify sustained host throughput, and separate analog input circuitry from the digital USB and clock domains to avoid data corruption.
Recommended
USB-to-Serial Bridge
The CY7C68013A-100AXI can implement a dedicated USB-to-serial bridge because it integrates USB transceiver hardware, endpoint logic, and an enhanced 8051 core with two USARTs in the FX2LP family. Firmware can translate between USB bulk transfers and serial traffic, maintain flow control, and expose configuration or diagnostic endpoints over USB. The 48 MHz processing speed supports protocol overhead and buffering, while the 100-pin package offers additional GPIO for status LEDs, control inputs, and peripheral selection. Firmware should implement short receive timeouts, deterministic buffer ownership, and host-driver compatibility testing before release.
Recommended
Custom USB Test Equipment
The CY7C68013A-100AXI suits custom USB test equipment in which a general-purpose host computer must communicate with specialized hardware over a deterministic peripheral interface. Its programmable endpoint architecture can separate command, status, and bulk-data traffic, while 40 GPIO provide interfaces for relays, indicators, clocks, and device-under-test control. The internal 16 KB RAM is useful for command parsing and short transaction buffers. Engineers should define descriptor behavior before PCB layout, reserve endpoints for diagnostics, and validate enumeration under the intended operating-system versions and cable conditions.
Recommended
Industrial USB Data Logger
The CY7C68013A-100AXI is appropriate for an industrial USB data logger that collects sensor or machine-status information and transfers it to a host computer. The industrial-grade ordering designation is relevant for deployments expected to operate beyond commercial-temperature conditions, while the 8051 core handles local control tasks. USB 2.0 bandwidth above 53 MB/s supports efficient batch transfers, and the 100-pin package exposes ample digital I/O. Production designs should still confirm the exact temperature limits, implement robust enumeration recovery, and include a data-integrity check in the firmware and host software.
Recommended
USB Peripherals and dongles
The CY7C68013A-100AXI can serve as the central controller in a USB peripheral or dongle requiring programmable device behavior rather than a fixed USB-to-serial bridge. Firmware can enumerate as a specialized composite device, route data between internal endpoints, and provide configuration through vendor-specific requests. Forty GPIO support status indicators, buttons, storage-control signals, or external converters, while the integrated transceiver minimizes the USB subsystem footprint. Designers should limit endpoint complexity, validate descriptor compatibility with target hosts, and use the datasheet reference layout for differential USB routing, clocking, and supply decoupling.

Key Differentiators
- Retains the high-density 100-pin interface while providing 40 GPIO (vs CY7C68013A-56PVXC)
- Uses the industrial-grade ordering designation (vs CY7C68013A-100AXC)
- Combines the 8051 processor and USB transceiver in one controller (vs CY7C68013-100AXC)
Design Notes
Route the USB differential pair as a controlled-impedance pair on a continuous reference plane, following the manufacturer layout reference without adding stubs or test pads that alter impedance. Keep the USB transceiver and crystal or clock circuitry close to their associated controller pins. The 100-pin TQFP footprint also requires careful escape routing for 40 GPIO; preserve short return paths and avoid switching-node or high-current traces beneath sensitive USB and clock nets.
Implement the supply network with the required local ceramic decoupling placed directly at the controller power pins. Use the manufacturer guidance for voltage tolerances, external memory, reset circuitry, and power sequencing rather than generic bulk-capacitor assumptions. Because the device is ROMless, external flash programming and boot-strapping must be included in the power-up design. Verify brownout, reset release, and enumeration behavior across the full supply range before production release.
Do not assume that every same-family 100-pin ordering code is firmware- and lifecycle-equivalent. Before substitution, compare the pin table, clock timing, USB descriptors, endpoint behavior, temperature grade, package markings, and qualification records. For CY7C68013A-100AXC, confirm that commercial-temperature operation is acceptable; for later or related ordering codes, validate the specific suffix meaning rather than treating it as a reel-code change.
Plan USB signal testing at the connector, controller, and any intermediate interface points because reflections or impedance discontinuities can appear as enumeration failures and intermittent transfer errors. Keep external-memory and GPIO routing away from the differential pair where practical, provide a continuous ground reference, and follow the controller's recommended crystal or clock network. Validate simultaneous high-speed transfers and maximum GPIO activity rather than testing only idle enumeration.
Estimated: USB high-speed operation and the 48 MHz embedded processor create dynamic supply demand even though the controller does not regulate a large external load. Scope input-rail droop during enumeration and sustained transfers, using the actual host, cable, and flash configuration. Preserve local bulk capacitance only as specified by the manufacturer, and avoid adding large capacitors directly to the USB pins because excessive capacitance can degrade signal integrity.
Compliance Information
No explicit compliance declaration for the exact ordering code was identified in the manufacturer information or distributor excerpts. The device is an industrial-grade USB interface controller rather than an automotive-qualified product.
