部品番号: CY7C68014A-128AXC ✓ 生産中CY7C68014A-128AXC 概要
An EZ-USB FX2LP is a USB 2.0 peripheral controller and application-specific microcontroller. In the broader hierarchy, it belongs to USB interface controllers, embedded microcontrollers, semiconductor ICs, and power-managed embedded processing systems. Unlike a conventional host controller, the device is intended to terminate a USB peripheral connection while providing programmable data-transfer and general-purpose I/O resources for external data-acquisition, communication, or control hardware.
The controller provides 16 KB of internal RAM for firmware and data buffering, 40 GPIO ports for device-side control signals, and an operating supply range of 3.0 V to 3.6 V. Its 8-bit data interface supports integration with parallel data sources and sinks, while the integrated 24 MHz clock provides the timing reference for USB signaling and firmware execution. The low-power EZ-USB FX2LP architecture is particularly useful in battery-powered equipment that must balance USB connectivity against energy consumption.
The CY7C68014A family is based on the highly integrated EZ-USB FX2 architecture. USB traffic is handled by dedicated controller logic, leaving the embedded processor available for application firmware. The 16 KB RAM can hold firmware, descriptors, status data, and transfer buffers, allowing a compact implementation without an external program-memory device. This ROMless architecture allows product-specific USB behavior to be programmed directly into the device.
Typical implementations include USB data-acquisition equipment, USB-to-parallel interface adapters, industrial control modules, test and measurement instruments, communications equipment, and battery-powered portable peripherals. The 40 GPIO count can support chip selects, control strobes, status indicators, and external interface signaling, while the parallel data bus can connect the controller to sensors, converters, memories, or legacy peripheral logic.
PCB design should preserve short USB traces, provide solid ground-plane continuity, and place support components close to their associated pins. Pay particular attention to power distribution, clock-related routing, input protection, and the requirements listed in the manufacturer datasheet for external memory, firmware programming, and USB signal routing.
This page combines manufacturer device facts, package information, application guidance, drop-in replacement analysis, and engineering design notes. It is structured to help developers evaluate USB controller integration, PCB footprint constraints, firmware requirements, peripheral I/O planning, and direct replacement decisions without relying only on a catalog specification summary.

主な用途
CY7C68014A-128AXC の用途: 6 件s: USB Data-Acquisition Equipment, Battery-Powered Portable Peripherals, USB-to-Parallel Interface Adapters, Industrial USB Control Modules, Test and Measurement Instruments, Communications and Protocol Adapters.
USB Data-Acquisition Equipment
The CY7C68014A-128AXC fits USB data-acquisition equipment that must combine device control with parallel sensor or converter data. Its 8-bit data bus provides a direct parallel interface, while 40 GPIO ports can carry channel-select strobes, range controls, trigger signals, and status indicators. The integrated 24 MHz EZ-USB FX2LP processor and 16 KB RAM support firmware, descriptors, and transfer buffering without requiring a separate USB interface IC. The primary design consideration is assigning the parallel data bus and control outputs to pins according to the manufacturer pin-description table while preserving USB signal integrity on the board.
おすすめ
Battery-Powered Portable Peripherals
The low-power EZ-USB FX2LP architecture makes the CY7C68014A-128AXC relevant to battery-powered portable peripherals that need USB connectivity without a separate host computer. Its 16 KB RAM, 40 GPIO ports, and 8-bit data bus can support compact control, status, and data-transfer functions. The 3.0 V to 3.6 V operating range also fits systems designed around a regulated low-voltage rail. Firmware should use the device's supported low-power states, disable unnecessary peripheral activity, and control external loads so that USB connection activity does not dominate the portable system's energy budget.
おすすめ
USB-to-Parallel Interface Adapters
A USB-to-parallel adapter can use the CY7C68014A-128AXC to bridge a USB 2.0 peripheral port to an 8-bit parallel interface. The integrated controller handles USB protocol behavior while the embedded processor manages buffering, control commands, and adapter-specific status. Forty GPIO ports provide additional chip-select, interrupt, handshake, and indicator outputs beyond the eight-bit data path. This consolidation is useful when the adapter needs programmable behavior, but the PCB must follow the manufacturer's USB routing and power guidance and must not depend on a generic parallel-interface pin map.
おすすめ
Industrial USB Control Modules
The CY7C68014A-128AXC can serve as the USB-facing controller in an industrial module that accepts commands from a USB host and operates external actuators, relays, indicators, or instrumentation. Its 40 GPIO ports allow multiple machine-control signals to be distributed around the 8-bit data bus, while the 8051-compatible core executes product-specific firmware. For industrial deployment, review the exact operating-temperature grade, isolation strategy, transient protection, grounding, and enclosure grounding requirements. Firmware should include device enumeration, connection-state handling, and safe output defaults before external machinery is enabled.
おすすめ
Test and Measurement Instruments
The CY7C68014A-128AXC is suitable for USB-controlled test and measurement peripherals that need a deterministic parallel data path and numerous control signals. An 8-bit bus can connect to front-end logic, converters, or counters, while GPIO outputs can select ranges, trigger captures, or operate front-panel indicators. Its 16 KB RAM provides space for transfer buffers and embedded control code, enabling a compact instrument architecture. Timing-critical paths should be separated from USB routing, and the external acquisition circuit should be designed around the controller's electrical limits and documented signal timing.
おすすめ
Communications and Protocol Adapters
Protocol adapters can use the CY7C68014A-128AXC to bridge USB 2.0 to a parallel or GPIO-intensive legacy interface. The embedded processor can format frames, manage USB transfers, and drive external communication hardware while the 40 GPIO ports provide chip selects, interrupt lines, and flow-control signals. The 16 KB RAM can accommodate protocol state, descriptors, and buffers for modest frame sizes. Firmware development should account for buffer occupancy and throughput, while layout should keep data and clock paths away from the USB differential pair to reduce coupling and data-integrity risk.

設計ノート
Route the USB differential pair as a controlled-impedance pair on the top signal layer with a continuous reference plane and minimal stubs. Keep the pair away from switching nodes and parallel data buses. Place any required USB termination or series-resistance network directly beside the controller pins. The 128-pin TQFP footprint offers many adjacent power and ground pins, so use a solid ground plane and short plane connections to minimize loop area and support return current.
Design the 3.0 V to 3.6 V supply rail to meet the device's local decoupling and USB operating requirements. Place bypass capacitors close to the supply and ground pins, with each capacitor connected to the nearest appropriate ground reference. Check the manufacturer's pin table before assigning VDD or ground pins because a 128-pin package can contain multiple related supply connections. Include brownout, sequencing, and load-transient margin in the power-budget review.
Separate the 8-bit data bus and 24 MHz clock from the USB differential pair. Use short point-to-point routes for the parallel interface, provide a continuous ground reference, and avoid crossing unrelated high-slew signals beneath the data path. If an external device drives the bus, verify its direction, level, timing, and contention behavior against the controller pin definitions. Account for setup and hold requirements when the bus connects to converters or memory outside the local device.
Do not treat CY7C68014A-100AXC as a drop-in replacement for the 128-pin target; its package pin count and PCB footprint differ. When evaluating CY7C68013A-128AXC, CY7C68013A-128AXI, or CY7C64713-128AXC, compare every power, ground, USB, clock, data-bus, and GPIO assignment in the manufacturer pin tables. Also review firmware startup, USB enumeration, endpoint configuration, and low-power behavior before releasing a substitution.
