Product details

Overview

CY7C68013-100AC from Cypress Semiconductor is a USB 2.0 peripheral controller integrating an enhanced 8051 microprocessor, USB 2.0 transceiver, serial interface engine (SIE), and General Programmable Interface (GPIF) in a single 100-pin TQFP package. It supports high-speed (480 Mbps) USB operation, features 16 KB internal RAM, four configurable endpoints (BULK/INTERRUPT/ISOCHRONOUS), and 8-/16-bit external FIFO interface for glueless connectivity to ATA, PCMCIA, or DSPs - deployed in USB-based data acquisition systems and firmware-upgradable instrumentation.

For engineers reviewing the CY7C68013-100AC datasheet, CY7C68013-100AC pinout, CY7C68013-100AC application, or CY7C68013-100AC equivalent, key selection criteria include USB 2.0 high-speed transceiver integration, GPIF programmability for custom parallel interface timing, endpoint RAM configuration flexibility, and boot options via USB/EPP/EEPROM - all critical for embedded USB peripheral design with deterministic latency and host-controlled renumerability.

Technical Context

The CY7C68013 implements a hardware-assisted USB protocol stack via its Smart Serial Interface Engine (SIE), offloading enumeration, token handling, and CRC generation from the 8051 core. Its GPIF operates at up to 40 MHz with fully programmable waveform logic, enabling direct interfacing to asynchronous or synchronous peripherals without external glue logic.

Endpoint buffering supports double/triple/quad configurations per endpoint, with dedicated 4 KB of endpoint RAM mapped into the 8051's XDATA space. Boot modes include USB download (default), EEPROM strap loading, or external memory fetch (128-pin only), and ReNumeration™ allows dynamic device descriptor updates post-connection.

Key Specifications

Parameter	Value and Actual Design Meaning
USB Speed	High-speed (480 Mbps) compliant; enables maximum USB 2.0 bandwidth utilization in peripheral mode.
Microcontroller Core	Enhanced 8051 running at up to 48 MHz; executes firmware from internal 16 KB RAM for deterministic real-time response.
Endpoint RAM	4 KB shared among four endpoints; supports double/triple/quad buffering to sustain high-throughput BULK transfers.
GPIF Clock	Up to 40 MHz internal IFCLK; provides programmable, cycle-accurate control over 8-/16-bit parallel interfaces.
FIFO Interface	Slave FIFO mode with 8- or 16-bit data bus; supports synchronous/asynchronous read/write with packet-end strobes.
Boot Sources	USB download (default), I²C EEPROM strap, or external memory (128-pin only); enables field firmware updates and flexible production programming.

Pinout & Package

Package: 100-pin Thin Quad Flatpack (TQFP), 14 × 20 × 1.4 mm, lead pitch 0.5 mm, RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
IFCLK	GPIF Interface Clock Input/Output	Configurable clock source for GPIF timing; can be internally generated (40 MHz max) or externally driven for precise synchronization.
SLCS#, SLRD#, SLWR#	Slave FIFO Control Signals	Active-low chip select, read strobe, and write strobe for glueless connection to external logic or processors.
PKTEND#	Packet End Strobe Input	Signals end of current data packet in Slave FIFO mode; enables precise packet boundary control for streaming protocols.
FLAGA–FLAGD	Programmable Status Flags	Four user-configurable flags indicating FIFO full/empty, commit status, or custom handshake conditions.
SDA, SCL	I²C Bus Interface	Supports EEPROM boot configuration and runtime device communication using standard I²C protocol (up to 400 kHz).

Key Features

Feature	Design Value
Smart Serial Interface Engine (SIE)	Hardware-accelerated USB protocol handling reduces 8051 CPU load by >90% during enumeration and data transfer.
ReNumeration™	Allows dynamic update of device descriptors (VID/PID/bcdDevice) after enumeration, enabling single-firmware multi-device support.
GPIF Waveform Programming	16-state, 5-tuple programmable state machine per GPIF channel; eliminates need for external CPLD/FPGA in custom interface designs.
Autopointer Access	Hardware auto-increment/decrement of endpoint buffer pointers during bulk transfers; ensures zero-cycle overhead pointer management.
USB Boot via USB	Firmware download directly over USB without external programmer; simplifies development, testing, and field upgrades.

Equivalent & Alternatives

The following parts are listed as comparable options for similar USB 2.0 peripheral controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
FX2LP CY7C68013A-100AC	Successor with lower power consumption (1.8 V core), reduced EMI, and identical pinout/package; retains same 8051/GPIF architecture.	Preferred for battery-powered or thermally constrained designs where power efficiency is critical.	Select when new designs require extended temperature range (–40°C to +85°C) and lower active current (<100 mA typical).
AN2131QC	Legacy FX1 predecessor; lacks high-speed USB transceiver, GPIF, and endpoint RAM - limited to full-speed (12 Mbps) only.	Suitable only for low-bandwidth HID or CDC-class devices without streaming requirements.	Use only for cost-sensitive legacy replacements where 480 Mbps throughput and programmable interface are unnecessary.

Compared with CY7C68013-100AC, the FX2LP offers identical functionality with improved power efficiency and thermal performance, while the AN2131QC sacrifices speed and flexibility for lower gate count and bill-of-materials cost - making the original FX2 optimal for high-throughput, field-upgradeable USB peripherals requiring full GPIF programmability.

FAQ

What boot methods does the CY7C68013-100AC support?

The CY7C68013-100AC supports three boot modes: default USB download (firmware loaded over USB at connection), I²C EEPROM strap loading (using VID/PID and firmware image stored in external EEPROM), and external memory fetch (only on 128-pin variant). The 100-pin version uses USB or EEPROM boot exclusively, with strap pins (PB0–PB3) selecting EEPROM address and boot source.

Can the GPIF interface be used with asynchronous peripherals?

Yes - the GPIF supports both synchronous and asynchronous timing modes. In asynchronous mode, it uses ready/wait handshaking (RDY/CTL lines) to interface with slow or variable-latency peripherals like SRAM, FPGA registers, or legacy ASICs, with programmable setup/hold/strobe timing controlled via GPIF waveforms.

How many endpoints does the CY7C68013-100AC support, and what types?

The CY7C68013-100AC supports four bidirectional endpoints (EP0–EP3), each configurable as BULK, INTERRUPT, or ISOCHRONOUS. EP0 is fixed for control transfers; EP1–EP3 support double/triple/quad buffering and can be independently assigned direction (IN/OUT) and type via firmware configuration of the EPxCFG registers.

Is the CY7C68013-100AC pin-compatible with newer FX2LP devices?

Yes - the CY7C68013-100AC is fully pin-compatible with the FX2LP CY7C68013A-100AC, including identical TQFP-100 footprint, power/ground pin mapping, and signal assignments. Firmware and hardware designs migrate directly, though FX2LP requires updated voltage regulators (1.8 V core) and may need minor timing adjustments for lower-power operation.
