CY7C64714-100AXC

Application Specific Microcontrollers Overview

The CY7C64714-100AXC is a full-speed USB peripheral controller from the EZ-USB FX1 family, manufactured by Infineon Technologies (formerly Cypress). It integrates an enhanced 8051 microprocessor, USB transceiver, and Smart SIE on a single chip. The device supports 3.3V operation with 5V tolerant inputs and draws no more than 65 mA in any mode. Key specifications include up to 48 MHz clock rate, 16 KBytes of internal RAM, four programmable BULK/INTERRUPT/ISOCHRONOUS endpoints, and an integrated I2C controller. It features fit, form, and function compatibility with the FX2LP series.

Application Specific Microcontrollers Feature Summary

• Single-chip integration of USB transceiver, SIE, and enhanced 8051 microprocessor
• Pin-compatible, object-code-compatible, and functionally compatible with FX2LP (CY7C68013A)
• Up to 48 MHz clock rate with four clocks per instruction cycle
• Four integrated FIFOs supporting master or slave operation

Application Specific Microcontrollers Applications

• DSL modems
• ATA interface devices
• Memory card readers
• Legacy conversion devices
• Wireless LAN equipment

Application Specific Microcontrollers Procurement Notes

Verify that the specific ordering suffix corresponds to the 100-pin TQFP package and lead-free construction as indicated by the model designation. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure supply chain sources provide valid traceability for this component.

Application Specific Microcontrollers Selection Notes

Select this component when a full-speed USB solution requiring direct upgrade path to FX2LP is needed. The 100-pin TQFP package offers a balance of I/O availability and footprint size. Consider the 16 KByte internal RAM limit for firmware complexity. Verify external memory requirements if code execution exceeds internal capacity limits.

Application Specific Microcontrollers Part Context

This part belongs to the EZ-USB FX1 family, which serves as a precursor to the higher-performance FX2 and FX2LP lines. The FX1 architecture provides a cost-effective entry point for USB peripheral designs while maintaining software compatibility with later generations. It is designed for applications requiring moderate data throughput and standard USB protocol handling.

Application Specific Microcontrollers Replacement Considerations

The CY7C68013A (FX2LP) is the confirmed functional and pin-compatible successor. Designers should verify that existing firmware utilizes only the subset of features available in the FX1 architecture when migrating to FX2LP.
