CY7C64613-80NC

Application Specific Microcontrollers Overview

The CY7C64613-80NC is an EZ-USB FX USB Microcontroller from Cypress Semiconductor, housed in an 80-pin PQFP package. It integrates a 3.3V enhanced 8051 microprocessor running at 24 MHz or 48 MHz with a USB Serial Interface Engine (SIE) and transceiver. The device features 8 KB of internal RAM for soft operation, 14 bulk/interrupt endpoints with 64-byte buffers, and 16 isochronous endpoints sharing 2 KB of buffer space. Key peripherals include four 64-byte slave FIFOs, a DMA engine capable of 48 MB/s transfers, and a General Programmable Interface (GPIF).

Application Specific Microcontrollers Feature Summary

• Integrated 3.3V enhanced 8051 core with 4-clock cycle operation and 8 KB internal RAM.
• USB 2.0 Full-Speed support with 14 Bulk/Interrupt endpoints and 16 Isochronous endpoints.
• Four integrated 64-byte Slave FIFOs with external clocking and bus width conversion capabilities.
• General Programmable Interface (GPIF) for direct connection to parallel interfaces like ATAPI.

Application Specific Microcontrollers Applications

• DSL modems
• ATAPI interface devices
• Memory card readers
• Legacy conversion devices

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix '-80NC' against the manufacturer's official documentation to confirm pinout compatibility and package dimensions. Ensure that the 80-pin PQFP variant matches the design requirements, as other variants such as the 52-pin or 128-pin packages offer different I/O availability and memory access options.

Application Specific Microcontrollers Selection Notes

Select this component when a high-performance USB controller with significant on-chip memory and flexible parallel interface options is required. The 80-pin package provides a balance between integration and available GPIOs, suitable for designs needing GPIF or multiple FIFOs without the footprint of the 128-pin version. Confirm EEPROM configuration needs for boot mode selection.

Application Specific Microcontrollers Part Context

The CY7C64613 belongs to the second-generation EZ-USB FX family, succeeding first-generation EZ-USB chips. It maintains code compatibility while offering higher performance through an enhanced 8051 and improved SIE. The part is designed to replace older USB controllers in applications requiring higher throughput and greater integration levels.

Application Specific Microcontrollers Replacement Considerations

The CY7C64613 is functionally compatible with the FX2LP (CY7C68013A) regarding object code, though the FX2LP offers additional features. Direct pin-for-pin replacement may require verification of specific pin assignments and voltage levels between the 80-pin FX1/FX derivatives and other FX family members.
