Product details

Overview

CY7C68013A-128AXC from Infineon Technologies (formerly Cypress Semiconductor) is a high-speed 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 128-pin TQFP package. It delivers up to 53 MB/s data throughput, supports four programmable BULK/INTERRUPT/ISOCHRONOUS endpoints with double/triple/quad buffering, and operates at 12/24/48 MHz CPU clock. It is widely deployed in USB-to-ATA, USB-to-FPGA, and legacy interface bridge applications requiring bus-powered operation and firmware flexibility.

For engineers reviewing the CY7C68013A-128AXC datasheet, CY7C68013A-128AXC pinout, CY7C68013A-128AXC application, or CY7C68013A-128AXC equivalent, key selection criteria include its 16 KB on-chip RAM, 40 GPIOs, 8-/16-bit external data interface, I²C controller (100/400 kHz), and GPIF waveform programmability - all critical for glueless interfacing with ASICs, DSPs, and storage controllers.

Technical Context

The CY7C68013A implements a hardware-accelerated USB 2.0 stack via its Smart SIE, offloading protocol handling (including SETUP/data phase separation, PID generation, CRC checking, and endpoint arbitration) from the 8051 core. Its 48-MHz-capable 8051 executes firmware from internal RAM (downloaded over USB or loaded from EEPROM) and features two USARTs, three timers, expanded interrupts, and dual data pointers.

GPIF operates as an autonomous state-machine-based interface controller supporting synchronous/asynchronous 8-/16-bit bus protocols with up to six RDY inputs and six CTL outputs. The integrated I²C controller runs at nominal 100 kHz or 400 kHz (measured ~85 kHz / ~300 kHz), and ECC generation is built-in for SmartMedia interfaces.

Use Scenario: Converting IDE/ATA hard drives or CompactFlash cards into USB mass-storage devices.

IC Role / Device Role / Timing Role: Acts as USB peripheral controller and ATA bus master; handles command translation, DMA setup, and sector-level data streaming.

Use Value: Enables legacy storage reuse via USB 2.0 Hi-Speed (up to 53 MB/s), eliminating need for host-side drivers or proprietary firmware stacks.

Use Scenario: Capturing uncompressed or compressed video streams from analog/digital sources (e.g., HDMI capture chips, TV tuners) to PC via USB.

IC Role / Device Role / Timing Role: Serves as isochronous data pump and buffer manager; uses triple-buffered endpoints and GPIF to sustain real-time 480p/720p transfer.

Use Value: Delivers deterministic latency and jitter-free streaming using hardware-managed FIFOs and dedicated USB interrupt vectors.

Legacy Peripheral Adapter

FPGA Configuration Loader

Use Scenario: Connecting parallel-port scanners, printers, or industrial I/O modules to modern USB hosts.

IC Role / Device Role / Timing Role: Implements EPP or IEEE 1284 protocol via GPIF with programmable strobe timing and RDY/CTL handshake.

Use Value: Replaces discrete logic or CPLDs with single-chip solution; supports hot-plug, vendor-class descriptors, and Windows INF-less installation.

Use Scenario: Loading configuration bitstreams into Xilinx or Intel FPGAs during system boot or field updates.

IC Role / Device Role / Timing Role: Functions as high-reliability SPI/I²C master or parallel slave loader; uses internal RAM to stage bitstream before clocked delivery.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
CY7C68014A-128AXC	Same pinout and firmware compatibility; lower suspend current (100 µA vs. 300 µA) due to optimized power gating.	Battery-powered devices where ultra-low standby power is mandatory (e.g., portable medical sensors).	Select when battery life >2× longer in suspend is required; otherwise, CY7C68013A offers identical functionality at lower unit cost.
FX2LP-CY7C68013A-100AXC	100-pin TQFP variant; same silicon, reduced GPIO count (40 → 32), no PORTA[7:0] - fewer address/data lines.	Space-constrained designs needing USB 2.0 peripheral control but with simpler external interface (e.g., single 8-bit bus).	Choose for smaller footprint and lower PCB layer count when full 40-GPIO capability is unnecessary.

Compared with CY7C68014A-128AXC, the CY7C68013A-128AXC trades 200 µA higher suspend current for lower cost and identical active-mode performance; versus the 100-pin variant, it adds 8 GPIOs and full 16-bit bus support - critical for ATA and high-throughput FPGA interfaces.

FAQ

What boot methods does the CY7C68013A-128AXC support?

The CY7C68013A-128AXC supports three boot modes: (1) firmware loaded from external EEPROM via I²C on power-up, (2) firmware downloaded over USB into internal RAM during enumeration, and (3) execution from external memory mapped via the 16-bit address/data bus. All modes are selectable via the MODE pins (PIN 1–3) at reset.

Can the CY7C68013A-128AXC operate as a USB host?

No. The CY7C68013A-128AXC is a USB 2.0 peripheral-only controller. It lacks OTG capability, host controller logic, or VBUS sensing circuitry. It must be connected to a USB host (e.g., PC, SoC) and cannot initiate transactions or enumerate other USB devices.

How many endpoints does the CY7C68013A-128AXC support, and what types?

The CY7C68013A-128AXC supports five endpoints: four programmable endpoints (BULK, INTERRUPT, or ISOCHRONOUS) with double/triple/quad buffering, plus one fixed 64-byte BULK/INTERRUPT endpoint. Endpoint 0 is reserved for CONTROL transfers and is not user-programmable.

Is the GPIF interface capable of synchronous and asynchronous operation?

Yes. The GPIF supports both synchronous (using IFCLK as reference) and asynchronous (using external RDY/CTL signals) timing modes. Waveform descriptors define exact setup/hold times, pulse widths, and state transitions - enabling precise emulation of ATA, EPP, and custom parallel protocols without external logic.
