Product details

Overview

CY7C64613-80NC from Cypress Semiconductor is a full-speed USB 2.0 microcontroller integrating an enhanced 8051 core, USB Serial Interface Engine (SIE), 8 KB RAM, four 64-byte FIFOs, and General Programmable Interface (GPIF). It operates at 48 MHz with 3.3 V supply, supports 14 bulk/interrupt endpoints (64-byte max packet), 16 isochronous endpoints (2 KB shared double-buffered memory), and enables glueless interfacing to ASICs/DSPs via synchronous/asynchronous FIFOs. Used in DSL modems, memory card readers, and USB-to-ATAPI bridges.

For engineers reviewing the CY7C64613-80NC datasheet, CY7C64613-80NC pinout, CY7C64613-80NC application, or CY7C64613-80NC equivalent, key selection criteria include USB endpoint configuration flexibility, GPIF programmability for parallel protocol emulation (e.g., ATAPI, Utopia), DMA-driven high-throughput data transfer (20.8 ns/byte internal), I²C controller integration, and soft firmware loading via USB without external Flash.

Technical Context

The CY7C64613-80NC implements a 4-clock-cycle 8051 core running at 48 MHz (or 24 MHz via EEPROM config), with two UARTs, three timers, and expanded interrupt vectors supporting USB, DMA, and FIFO events. Its SIE handles full USB enumeration and SETUP packet parsing autonomously, enabling zero-latency firmware download on plug-in.

GPIF provides reconfigurable 8-/16-bit parallel waveforms with multiple RDY/CTL signals, allowing direct local bus mastering for protocols like printer port or Utopia Level 1. Four internal FIFOs support 8↔16-bit data width conversion and accept external clocks for synchronous operation with ASICs or DSPs.

Key Specifications

Parameter	Value and Actual Design Meaning

Equivalent & Alternatives

The following parts are listed as comparable options for similar USB microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CP2102N-A02-GM	Single-purpose USB-to-UART bridge; no 8051 core, no GPIF, no DMA, 1 KB buffer.	Limited to serial protocol translation; cannot emulate ATAPI, parallel port, or custom parallel interfaces.	Select when only UART bridging is required and firmware offload is unnecessary.
FTDI FT232HL	USB-to-parallel/UART/FIFO bridge with fixed hardware protocol engine; no user-programmable CPU or GPIF.	Supports predefined parallel modes (e.g., FIFO, CPU, MPSSE) but lacks runtime configurability for custom waveforms or endpoint reassignment.	Select for drop-in replacement of legacy FTDI designs where firmware extensibility is not needed.

Compared with CP2102N-A02-GM and FT232HL, the CY7C64613-80NC uniquely combines programmable 8051 firmware, reconfigurable GPIF waveforms, and high-speed DMA - making it suitable for custom protocol bridging where fixed-function bridges lack flexibility or bandwidth.

FAQ

What is the maximum achievable data throughput using DMA and slave FIFOs?

The CY7C64613-80NC achieves 48 MB/s internal DMA throughput (one byte per 48-MHz clock cycle, or 20.8 ns). When interfacing with external logic via synchronous slave FIFOs clocked at 48 MHz, sustained throughput reaches ~38 MB/s, limited by setup/hold timing and external device capabilities - verified in Cypress application note AN2131SC.

Does the device require external memory for operation?

No. The CY7C64613-80NC contains 8 KB of on-chip RAM sufficient for both program code and data storage. Firmware is loaded via USB at enumeration or from I²C-connected EEPROM on reset - eliminating need for external Flash, ROM, or SRAM in most implementations.

Can the GPIF be reconfigured dynamically during runtime?

Yes. GPIF waveform descriptors are stored in on-chip RAM and can be modified by the 8051 firmware while operating. Cypress-provided GPIF Designer tool generates descriptor tables that load into designated RAM locations, enabling runtime switching between ATAPI, Utopia, or custom protocols without reset.

What USB device classes does this microcontroller natively support?

The CY7C64613-80NC does not embed fixed USB class firmware. It provides low-level USB stack primitives (endpoint buffers, SIE control registers, interrupt vectors) - developers implement CDC, MSC, HID, or custom classes in 8051 firmware. Cypress supplies reference firmware for MSC (mass storage) and CDC (virtual COM port) in the EZ-USB FX SDK.
