CY7C68015A-56LFXC - USB 2.0 FX2LP Controller | Cypress
部品番号: CY7C68015A-56LFXC ✓ 生産中CY7C68015A-56LFXC 概要
An EZ-USB FX2LP is a highly integrated USB 2.0 controller in the broader semiconductor and embedded-controller hierarchy. It is designed for low-power USB peripheral applications requiring high-speed data transfer, flexible endpoint control, and firmware-based protocol implementation. Unlike a simple USB interface adapter, the smart SIE can handle low-level USB transactions while the embedded processor manages device-specific behavior, data movement, and host communication.
The verified product information identifies the CY7C68015A-56LFXC as a ROMless 8051 EZ-USB FX2LP USB microcontroller in a 56-VFQFN exposed-pad package. It supports USB 2.0 high-speed operation and includes a single-chip USB 2.0 transceiver, smart SIE, and enhanced 8051 microprocessor. The low-power FX2LP positioning is especially relevant to battery-powered and portable equipment where USB connectivity must coexist with constrained power budgets.
The integrated architecture reduces the component count required for a USB peripheral design by combining protocol handling, control logic, and general-purpose processing. Programmable GPIOs can support control signals, indicators, and external interfaces, while the ROMless architecture allows the application firmware to be loaded according to the product's programming and boot architecture. Exact RAM, GPIO, clock, endpoint, and electrical limits must be confirmed in the current manufacturer datasheet before schematic release.
Typical applications include USB-to-serial adapters, data acquisition equipment, test and measurement instruments, industrial peripheral interfaces, storage and communication adapters, and portable USB-connected products. The device is particularly useful where a host bus requires protocol-specific buffering or endpoint handling beyond a basic UART or SPI USB bridge.
A critical design consideration is package and pinout verification. The supplied search results confirm the 56-VFQFN exposed-pad package but do not provide the complete numbered pin list, so the design must be checked against the manufacturer datasheet land pattern, exposed-pad connection, decoupling requirements, and signal-routing guidance before fabrication.
This page consolidates verified distributor and manufacturer-listing information, same-package family alternatives, comparison fields, and practical design cautions. It separates confirmed facts from unavailable specifications so engineers can identify what still requires validation from the manufacturer datasheet.

主な用途
CY7C68015A-56LFXC の用途: 6 件s: USB-to-Serial Data Acquisition Adapters, Test and Measurement Instruments, Industrial USB Peripheral Interfaces, Portable USB-Connected Equipment, USB Storage and Communication Bridges, USB Protocol Development and Learning Kits.
USB-to-Serial Data Acquisition Adapters
The CY7C68015A-56LFXC fits a custom USB-to-serial adapter because it combines a 3.3 V enhanced 8051 core, smart SIE, and integrated USB 2.0 transceiver in one ROMless controller. Firmware can implement vendor-specific framing, buffering, and control commands rather than relying on a fixed bridge function. In an acquisition product, the host can exchange measurement or configuration packets over USB while GPIO controls sampling, alert, or status signals. Compared with a basic USB-UART bridge, the programmable architecture allows protocol-specific behavior and multiple endpoints. RAM capacity, endpoint limits, and GPIO assignments are not provided in the verified snippets and must be confirmed from the manufacturer datasheet before final channel counts or buffer sizes are specified.
おすすめ
Test and Measurement Instruments
The CY7C68015A-56LFXC is suitable for test and measurement equipment that connects an instrument to a USB host and requires programmable device behavior. Its enhanced 8051 processor, smart SIE, and integrated USB 2.0 transceiver can support control commands, status reporting, and bulk data transfer within a compact 56-VFQFN footprint. A 3.3 V operating supply also aligns with many modern instrument boards. The main design benefit is consolidating USB protocol handling with application control, reducing external interface circuitry. Designers still need to verify exact clock, endpoint, RAM, and timing limits from the Cypress Semiconductor EZ-USB FX2LP datasheet and preserve adequate layout separation between the USB differential pair and sensitive measurement paths.
おすすめ
Industrial USB Peripheral Interfaces
The CY7C68015A-56LFXC can be used in industrial peripheral interfaces where USB provides a high-speed host connection and the equipment needs local control logic. Its integrated transceiver and smart SIE reduce the need for separate USB interface components, while the enhanced 8051 core executes device-specific protocols. GPIO can be assigned to relays, indicators, interlocks, or configuration controls after the final pin map is verified. Compared with a discrete USB interface implementation, the integrated controller simplifies the design but concentrates USB signal-integrity and firmware risks in one IC. Industrial qualification, ESD protection, input voltage tolerance, and operating-temperature limits are not stated in the supplied search data and must be confirmed from the manufacturer datasheet before deployment.
おすすめ
Portable USB-Connected Equipment
The low-power EZ-USB FX2LP positioning makes the CY7C68015A-56LFXC relevant to portable equipment that connects to a USB host while maintaining a 3.3 V supply. The controller consolidates the USB transceiver, smart SIE, and enhanced 8051 processing into a 56-VFQFN package, allowing a compact implementation for accessories, portable analyzers, and compact data-transfer products. System-level battery life depends on the device's actual active and suspend currents, which are not supplied here, so they must be measured from the datasheet and design. Firmware should enumerate promptly, avoid unnecessary polling, and suspend peripheral loads when the host stops the session. ESD protection and connector mechanics also remain external design responsibilities.
おすすめ
USB Storage and Communication Bridges
The CY7C68015A-56LFXC can implement a storage or communication bridge when the bridge requires programmable firmware, buffering, or vendor-specific control rather than a fixed function. Its enhanced 8051 processor and smart SIE can coordinate USB transfers with an external storage controller or communications transceiver. The 56-VFQFN exposed-pad package supports dense board layouts but requires careful thermal-pad and copper planning, especially during sustained USB transfers. Compared with a dedicated bridge IC, the FX2LP offers more implementation flexibility at the cost of firmware and board-development effort. The supplied data does not state maximum transfer rate, endpoint count, or sustained power, so those limits must be taken from the current manufacturer datasheet before sizing storage throughput or thermal margins.
おすすめ
USB Protocol Development and Learning Kits
The CY7C68015A-56LFXC is well suited to USB protocol development because its ROMless architecture lets engineers program the enhanced 8051 core and configure the smart SIE for specific device functions. It can be used to create test firmware that exercises enumeration, endpoint transfers, vendor requests, suspend behavior, and application-specific protocols. The integrated USB 2.0 transceiver avoids duplicating the host-to-device physical layer, while the 56-VFQFN package is useful for compact evaluation hardware. Developers should treat the datasheet pinout and timing diagrams as authoritative because the supplied snippets do not expose the complete pin assignments or electrical characteristics. A prototype also needs correct USB pull-up control, connector protection, decoupling, and a download or programming method compatible with the chosen firmware architecture.

設計ノート
Treat the D+ and D+ pairs as a controlled-impedance USB 2.0 differential route. Keep the USB connector, protection device, controller transceiver pins, and test points in a short continuous path, minimize stub branches, and provide a continuous ground reference beneath the pair. The verified snippets do not include the manufacturer layout recommendations, so trace geometry, impedance target, and spacing must be taken from the current EZ-USB FX2LP datasheet and the associated reference design.
Decouple the 3.3 V supply locally and route both power and ground connections to the 56-VFQFN exposed pad using the manufacturer-recommended via and copper arrangement. The exposed pad is part of the thermal and electrical solution and must not be treated as an optional pad. Exact capacitor values, voltage tolerances, and via counts are not present in the supplied data, so use the datasheet's typical application circuit and power-layout guidance rather than generic bulk-capacitor values.
Do not substitute a related CY7C680xx controller solely because the order code and 56-pin package appear similar. Related listings include CY7C68013A, CY7C68014A, CY7C68016A, CY7C68023, and CY7C68033 variants, but the supplied search results do not expose their complete pin maps, GPIO assignments, endpoint behavior, or timing. Before replacement, compare every connected net, USB pull-up control, clock source, reset behavior, and exposed-pad connection against the current manufacturer documentation.
Separate the USB differential pair from clocks, switching regulators, crystal or oscillator circuitry, and high-current outputs. Maintain the shortest practical connection to the connector and protection components, and avoid routing the pair around split ground-plane boundaries. Use common-mode choke or discrete filtering only after checking its impact on USB signal integrity. The supplied evidence establishes high-speed USB 2.0 operation but does not provide the device's impedance or layout values, so verify them in the manufacturer datasheet.
Estimate dissipated power from the actual 3.3 V supply, average USB activity, and measured core current rather than assuming worst-case continuous operation. The exposed-pad package can improve heat spreading, but its effectiveness depends on solder quality, via geometry, copper area, and board construction. No thermal-resistance value is supplied, so no junction-temperature calculation is presented. Validate the assembled PCB under sustained transfers and use the manufacturer thermal data to set the acceptable ambient and loading limits.
コンプライアンス情報
The supplied verified snippets do not extract compliance declarations. RoHS and REACH status must be confirmed from the current manufacturer product page, product documentation, or distributor declaration before qualification.
