Product details

Overview

CY7C64613-128NC from Cypress Semiconductor is a full-speed USB 2.0 microcontroller integrating an enhanced 8051 core, USB Serial Interface Engine (SIE), 8 KB RAM, 4 × 64-byte internal FIFOs, and General Programmable Interface (GPIF). It operates at 48 MHz (4-clock-cycle), supports 14 bulk/interrupt endpoints (64-byte buffers), and 16 isochronous endpoints sharing 2 KB double-buffered memory. Used in DSL modems, memory card readers, and USB-to-ATAPI bridge designs.

For engineers reviewing the CY7C64613-128NC datasheet, CY7C64613-128NC pinout, CY7C64613-128NC application, or CY7C64613-128NC equivalent, key selection criteria include USB endpoint configuration flexibility, GPIF programmability for parallel interface emulation, DMA transfer speed (20.8 ns/byte), I²C controller support (100/400 kHz), and 128-pin PQFP package compatibility with external memory expansion.

Technical Context

The device implements a 48-MHz 4-clock-per-cycle 8051 core with two UARTs, three timers, and dual data pointers, executing firmware loaded via USB or I²C EEPROM. Its intelligent SIE handles enumeration and SETUP packet parsing autonomously, enabling "soft" operation without mask ROM or Flash.

GPIF provides reconfigurable 8-/16-bit parallel waveform generation with multiple RDY inputs and CTL outputs, supporting protocols like ATAPI and Utopia. DMA enables zero-wait-state transfers between slave FIFOs, RAM, and ports-critical for real-time isochronous streaming in cameras and audio devices.

Key Specifications

Parameter	Value and Actual Design Meaning
USB Speed	Full-speed (12 Mbps); compliant with USB 2.0 specification for host communication without external transceiver.
Microcontroller Core	Enhanced 8051 running at 48 MHz (4 clocks/cycle); delivers ~12 MIPS performance for real-time USB protocol handling.
RAM Size	8 KB on-chip SRAM; serves as both program and data memory, enabling field-upgradable firmware via USB download.
Endpoint Configuration	14 configurable bulk/interrupt endpoints (64-byte buffers each) + 16 isochronous endpoints sharing 2 KB double-buffered FIFO space.
FIFO Resources	Four independent 64-byte general-purpose FIFOs; support synchronous/asynchronous modes and 8-/16-bit bus conversion for ASIC/DSP interfacing.
GPIF Width	Programmable 8- or 16-bit parallel interface; eliminates glue logic when connecting to ATA, printer, or custom logic buses.
I²C Controller	Integrated master/slave I²C interface supporting 100 kHz and 400 kHz modes; used for EEPROM boot loading and peripheral control.

Pinout & Package

The CY7C64613-128NC is housed in a 128-pin Plastic Quad Flat Package (PQFP) with 0.4 mm lead pitch, exposing full 8051 address/data buses (A0–A15, D0–D7), control signals (RD#, WR#, OE#, CS#, PSEN), USB differential pair (D+, D−), and dedicated GPIF/FIFO I/O banks.

Pin/Terminal	Circuit Role	Design Meaning
D+ / D−	USB Differential Transceiver I/O	Direct connection to USB upstream port; integrated transceiver eliminates need for external PHY.
INT2	USB Interrupt Output	Vectored interrupt signal indicating USB event (e.g., token received, SOF); reduces polling overhead.
SLCS#, SLRD#, SLWR#	Slave FIFO Control	Enable, read, and write strobes for 4×64-byte internal FIFOs; support glueless interface to external logic or DSPs.
CTL0–CTL3	GPIF Control Outputs	Configurable active-high/low control signals driven by GPIF state machine; used for handshaking with peripherals.
RDY0–RDY2	GPIF Ready Inputs	External synchronization inputs allowing GPIF to pause or extend waveform cycles based on peripheral readiness.
SCL / SDA	I²C Bus Interface	Open-drain bidirectional lines for bootloading firmware from external EEPROM or configuring system parameters.

Key Features

Feature	Design Value
Soft Operation Firmware Loading	Code execution begins from 8 KB RAM preloaded via USB or I²C EEPROM-no external Flash required for field updates.
High-Speed DMA Engine	Transfers data between FIFOs, RAM, and ports at 20.8 ns/byte (48 MHz clock), enabling sustained >40 MB/s throughput in synchronous mode.
General Programmable Interface (GPIF)	Hardware-programmable 8-/16-bit parallel interface with up to 16-state waveforms and 3 RDY inputs-replaces FPGA glue logic in ATA/PCIe bridge designs.
Double-Buffered Isochronous Support	2 KB shared memory split across 16 ISO endpoints with 16-byte granularity; ensures jitter-free audio/video streaming without host-side buffering.
Enhanced 8051 Architecture	Four clocks/cycle execution, dual DPTR, expanded interrupt vectoring (INT2/INT4), and SFR-mapped I/O-reduces instruction count for bit-level GPIO control.

Applications

IC Role / Device Role / Timing Role: USB-to-ATAPI protocol converter with GPIF emulating ATA timing and DMA offloading host CPU.

Use Value: Eliminates external CPLD/FPGA; 48-MHz 8051 processes command translation while GPIF handles strobe timing and RDY handshaking.

Use Scenario: Connecting SD/MMC/CF cards to PC via USB 2.0 without proprietary drivers.

IC Role / Device Role / Timing Role: USB mass storage class (MSC) device controller with built-in FAT-aware firmware and isochronous buffer management.

Use Value: Four 64-byte FIFOs absorb print spool bursts; vectored interrupts reduce latency during status polling.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
CY7C68013A-128AXC	Successor FX2LP device with 8051 core, 16 KB RAM, and improved GPIF (56 pins vs. 48), but no native I²C controller.	Requires external I²C EEPROM for boot; better suited for high-throughput data acquisition where RAM size matters more than I²C integration.	Select when needing larger buffer space and higher GPIF pin count; avoid if I²C-based EEPROM boot is mandatory.
FTDI FT232H	USB-to-HS UART/BITBANG bridge IC with no embedded processor; relies on host-driven protocol translation.	Lacks local intelligence for isochronous streaming or GPIF waveform generation; limited to serial or GPIO-based interfaces.	Select only for simple UART or GPIO bridging; not viable for ATAPI, camera, or real-time protocol emulation requiring on-chip processing.

Compared with CY7C64613-128NC, CY7C68013A offers greater RAM and GPIF flexibility but removes integrated I²C, while FT232H sacrifices all local processing capability for simplicity-making CY7C64613-128NC uniquely balanced for embedded USB protocol conversion with minimal external components.

FAQ

Does CY7C64613-128NC require external crystal or oscillator?

Yes-it requires a 12 MHz fundamental-mode crystal connected to XIN/XOUT pins. An internal PLL multiplies this to 48 MHz for the USB SIE and 8051 core. The crystal must meet ±100 ppm stability for USB full-speed compliance; ceramic resonators are not recommended due to insufficient accuracy.

Can CY7C64613-128NC operate without USB connection after boot?

Yes-firmware can be loaded from an I²C-connected EEPROM at reset, enabling standalone operation. The EEPROM must contain valid 8051 code and configuration bytes; default boot mode is USB download, but EEPROM presence overrides this behavior automatically.

What is the maximum data rate achievable using GPIF in synchronous mode?

In synchronous 16-bit mode with internal 48 MHz clock, GPIF achieves up to 24 MB/s (16 bits × 48 MHz ÷ 8). Real-world throughput depends on waveform descriptor efficiency and RDY signal timing; measured benchmarks show sustained 18–21 MB/s with optimized descriptors and tight peripheral handshaking.

How many GPIO pins are available in the 128-pin PQFP package?

The CY7C64613-128NC exposes 72 dedicated GPIO pins across Ports A–E, plus additional multifunction pins (e.g., GPIF data lines, FIFO controls, I²C, UART) that can be configured as general-purpose I/O when their primary function is unused-totaling over 90 usable I/O signals in typical configurations.
