N.º da peça: CY7C68015A-56LTXC ✓ AtivoCY7C68015A-56LTXC Visão geral
An EZ-USB FX2LP controller is an application-specific USB peripheral controller that combines a fast 8051-compatible microprocessor with dedicated USB 2.0 full-speed and low-speed device hardware. Within the product hierarchy, it is a USB interface controller, application-specific microcontroller, embedded processor, and USB 2.0 peripheral controller. Its RAM may be used for firmware, descriptors, endpoint buffers, and application data rather than storing a fixed program image in on-chip ROM.
The principal features include 16 KB of RAM, 24 GPIOs, a 48 MHz core clock, and operation across a 3 V to 3.6 V supply range. USB connectivity is integrated on the device, while I2C and USART provide paths to sensors, EEPROMs, transceivers, and external interface controllers. These resources make the controller suitable for compact USB peripheral equipment where high-speed host-side data transfer must coexist with embedded control functions.
FX2LP devices use an 8051-compatible architecture and register-based firmware programming. Endpoint configuration, descriptor handling, and data-transfer routines are implemented in firmware, allowing product behavior to be adapted without changing the external USB interface hardware. Exact endpoint-buffer capacity and all detailed electrical characteristics should be confirmed in the manufacturer datasheet for the final production design.
Typical applications include USB-to-serial adapters, data-acquisition front ends, logic analyzers, oscilloscope interfaces, industrial control panels, test equipment, and portable instruments. The exposed-pad package supports compact surface-mount layouts, while the 3 V to 3.6 V operating range fits designs powered from regulated battery or USB-derived rails.
PCB designers should follow the manufacturer pin-description table when assigning the exposed pad, supply pins, and ground connections. Place high-frequency decoupling capacitors close to the device, preserve the recommended USB data-routing geometry, and confirm that the PCB footprint and paste pattern match the 56-VFQFN package used by the selected ordering code.
This page combines the manufacturer device description with family-level alternatives, package comparisons, sourcing guidance, and practical integration considerations. It is intended to help engineers determine whether the CY7C68015A-56LTXC fits a USB peripheral design before beginning firmware and PCB implementation.

Aplicações típicas
CY7C68015A-56LTXC é adequado para 6 aplicaçãos: USB-to-Serial and USB-to-UART Bridges, Portable Data-Acquisition Systems, Test-and-Measurement Instrument Interfaces, Industrial USB Control Panels, USB Logic and Protocol Analyzers, Battery-Powered USB Peripherals.
USB-to-Serial and USB-to-UART Bridges
The CY7C68015A-56LTXC fits compact USB-to-serial products because its integrated USB 2.0 interface, USART, 48 MHz 8051 core, and 16 KB RAM support endpoint handling, protocol framing, and buffering in one controller. Firmware can implement USB descriptors and translate commands between a host and an RS-232 or RS-485 transceiver. The 24 GPIOs also support status indicators, handshake lines, and user-interface controls. Because the device is ROMless, production units require programmed firmware and configuration storage.
Recomendado
Portable Data-Acquisition Systems
The CY7C68015A-56LTXC is appropriate for portable instrumentation that transfers sampled data over USB while performing local control. Its 48 MHz 8051-compatible core can manage acquisition timing, command processing, and USB endpoint transfers, while 16 KB of RAM provides space for buffers and working variables. The 3 V to 3.6 V operating range suits compact regulated battery-powered designs. Engineers should partition RAM carefully when combining high-rate acquisition, descriptors, and control functions.
Recomendado
Test-and-Measurement Instrument Interfaces
The CY7C68015A-56LTXC can serve as the USB interface engine in oscilloscope, logic-analyzer, and laboratory instrument designs. USB 2.0 provides the high-speed host connection, while the 8051 core handles device commands, status reporting, and data formatting. Its 24 GPIOs can support trigger, range, acquisition, and front-panel control signals, and I2C can connect to configuration EEPROMs or sensors. Firmware planning must include endpoint allocation, maximum transfer rates, and buffer memory.
Recomendado
Industrial USB Control Panels
The CY7C68015A-56LTXC supports industrial control panels that connect to a PC over USB while operating relays, indicators, sensors, and local control logic. Its 24 GPIOs offer a practical interface for digital inputs and outputs, while I2C expands access to sensors, EEPROMs, or expanders. The integrated USB interface reduces the need for a separate USB bridge controller. Designers should add suitable isolation, surge protection, and grounding when the panel connects to external industrial wiring.
Recomendado
USB Logic and Protocol Analyzers
The CY7C68015A-56LTXC can support low-speed USB peripheral analyzers, protocol testers, and programmable logic accessories. Its 8051 core handles enumeration and test commands, while 16 KB of RAM can hold packet descriptors, counters, and captured event information. GPIO pins can drive stimulus signals or monitor device state, and USB connectivity gives the analyzer direct host access. For sustained high-rate capture, confirm endpoint bandwidth and RAM allocation before fixing the firmware architecture.
Recomendado
Battery-Powered USB Peripherals
The CY7C68015A-56LTXC targets compact USB peripherals operating from a regulated 3 V to 3.6 V source, including portable readers, analyzers, and specialty adapters. Its integrated USB controller, 16 KB RAM, and 24 GPIOs consolidate several functions into one package, reducing board area. Low-voltage operation also simplifies battery regulator selection. System-level energy use still depends on the chosen firmware activity, USB bus state, indicator circuits, and the power consumed by attached external components.

Notas de projeto
Use the manufacturer package drawing for the 56-VFQFN exposed-pad footprint and verify the ordering-code-specific land pattern before releasing artwork. Route the USB differential pair as a short, symmetric pair with a continuous reference plane, and place the recommended USB termination and decoupling components close to their associated pins. The exposed pad requires a thermal-via pattern and adequate copper area for heat dissipation.
Design the power rail for a 3 V to 3.6 V operating range and keep the USB transceiver, digital core, and I/O domains within their specified limits. Place bulk and high-frequency bypass capacitors at the supply entry point and close to the controller pins. Estimate the average and peak load from the core, USB PHY, attached I/O, pull networks, and external level-shifting circuits before choosing regulator capacity.
Do not treat family compatibility as automatic firmware compatibility. Before substituting another FX2LP member, compare reset behavior, internal oscillator accuracy, endpoint-buffer allocation, USB descriptors, interrupt vectors, and register defaults. CY7C68013A-56LTXI is described as pin-compatible and register-compatible in many cases, but those exceptional cases still require a controlled firmware and hardware verification cycle.
Reserve isolation between USB data routing, clock-sensitive nets, and noisy external interfaces. Keep oscillator and clock paths short, route ground returns without splits beneath high-speed data pairs, and connect the exposed pad to the ground plane through the recommended via pattern. In test and measurement products, separate analog inputs from digital control paths and use controlled grounding to prevent USB and switching circuitry from corrupting measurements.
Informações de conformidade
AEC-Q100 qualification does not apply to this USB peripheral controller. RoHS, REACH, lead-free, halogen-free, and conflict-minerals status require confirmation from the manufacturer product documentation.
