CY7C64613-128NC

Application Specific Microcontrollers Overview

The CY7C64613-128NC is a Cypress EZ-USB FX microcontroller featuring an enhanced 8051 core, USB Serial Interface Engine (SIE), and integrated transceiver. It operates at 48 MHz or 24 MHz with 8 KB of internal RAM and supports soft operation via USB download or EEPROM loading. The device includes 14 Bulk/Interrupt endpoints with 64-byte buffers, 16 Isochronous endpoints sharing 2 KB of buffer space, four 64-byte slave FIFOs, and a General Programmable Interface (GPIF). It utilizes a 12-MHz crystal input and provides full external memory bus access in the 128-pin PQFP package.

Application Specific Microcontrollers Procurement Notes

Verify the manufacturer designation as Cypress Semiconductor Corporation within official documentation, noting that Infineon Technologies acquired Cypress. Confirm the specific ordering suffix '-128NC' corresponds to the 128-pin PQFP package variant in the current datasheet revision 38-08005. Ensure compatibility with the specified 3.3-volt operating conditions and 12-MHz crystal requirements.

Application Specific Microcontrollers Selection Notes

Select this component when high-speed USB data transfer is required alongside local bus mastering capabilities. The 128-pin package is necessary for designs requiring full access to the 8051 address and data buses for glueless external memory expansion. Consider the GPIF and DMA features for applications interfacing with ASICs, DSPs, or parallel protocols like ATAPI without additional glue logic.

Application Specific Microcontrollers Part Context

The CY7C64613 belongs to the EZ-USB FX family, representing a second-generation full-speed USB microcontroller from Cypress Semiconductor. It enhances previous EZ-USB products by offering faster operation, increased integration, and improved I/O performance. The FX series maintains code compatibility with earlier generations while providing more efficient data transfer mechanisms through its advanced DMA and FIFO structures.

Application Specific Microcontrollers Replacement Considerations

Public confirmed substitute part numbers include the CY7C64713 and CY7C64714 FX1 variants. These replacements offer migration paths from the FX generation to the FX1 generation, maintaining functional similarities while potentially updating interface or performance characteristics.
