Product details
Overview
CY7C68014A-56LTXC from Infineon Technologies (formerly Cypress Semiconductor) is a USB 2.0 high-speed peripheral controller integrating an enhanced 8051 microprocessor, USB 2.0 transceiver, serial interface engine (SIE), and GPIF™ programmable interface in a single 56-pin QFN package. It delivers up to 53 MB/s data throughput, supports 48/24/12 MHz CPU clocking, features 16 KB on-chip RAM, and draws only 100 µA typical in suspend mode - enabling bus- and battery-powered USB peripherals such as portable video recorders and memory card readers.
For engineers reviewing the CY7C68014A-56LTXC datasheet, CY7C68014A-56LTXC pinout, CY7C68014A-56LTXC application, or CY7C68014A-56LTXC equivalent, key selection criteria include USB 2.0 Hi-Speed certification (TID #40460272), 8/16-bit external data interface capability, quad-buffered endpoints, I²C controller operation at 100/400 kHz, and GPIF waveform programmability for glueless ASIC/DSP interfacing.
Technical Context
The CY7C68014A implements a hardware-accelerated USB 2.0 protocol stack via its Smart SIE, offloading enumeration, token handling, and error recovery from the 8051 core. Its integrated PLL generates 480 MHz for the PHY while deriving 48/24/12 MHz clocks for the CPU - all configurable via CPUCS register at runtime.
GPIF™ operates as a fully autonomous state-machine-based interface engine with six RDY inputs and six CTL outputs, supporting synchronous/asynchronous strobes and automatic 8-/16-bit bus width conversion. Endpoint buffering includes four programmable BULK/INTERRUPT/ISOCHRONOUS endpoints with double/triple/quad options plus one additional 64-byte BULK/INTERRUPT endpoint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Speed | Hi-Speed (480 Mbps) and Full-Speed (12 Mbps); certified per USB-IF TID #40460272 - ensures interoperability with host controllers without custom driver development. |
| CPU Core | Enhanced 8051 running at 12/24/48 MHz (4 clocks/instruction); enables real-time firmware control of USB transfers and peripheral logic without external co-processor. |
| On-chip RAM | 16 KB code/data RAM; eliminates need for external program memory in most firmware deployments - reduces BOM cost and PCB footprint. |
| Suspend Current | 100 µA typical; meets USB battery-powered device requirements for extended standby life in portable applications. |
| Endpoint Buffers | Four configurable BULK/INTERRUPT/ISOCHRONOUS endpoints + one 64-byte BULK/INTERRUPT endpoint; supports concurrent high-bandwidth streaming and low-latency control transfers. |
| I²C Controller | Integrated master-only I²C interface operating at ~85 kHz (100 kHz setting) or ~300 kHz (400 kHz setting); enables direct connection to EEPROMs, sensors, or PMICs without external bus controller. |
| GPIF Interface | Programmable 8-/16-bit parallel interface with up to 6 RDY inputs and 6 CTL outputs; allows direct, glueless connection to FPGA, DSP, ATA, or PCMCIA without external logic. |
Pinout & Package
Package: 56-pin QFN (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, with 24 GPIOs and exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D+ / D− | USB 2.0 differential data pair | Direct connection to USB connector; internal 1.5 kΩ pull-up on D+ enables Hi-Speed negotiation and device enumeration. |
| CLKOUT | Configurable CPU clock output | Provides 12/24/48 MHz square wave for synchronizing external logic or debugging clock domain alignment. |
| SLCS#, SLRD#, SLWR# | Slave FIFO control signals | Enable direct 8-/16-bit asynchronous read/write to endpoint FIFOs - bypasses 8051 for maximum throughput in streaming applications. |
| CTL[5:0] | GPIF control outputs | Drive external device control lines (e.g., chip select, write enable) based on programmable state machine transitions. |
| RDY[5:0] | GPIF ready inputs | Signal external device readiness (e.g., FIFO full/empty, handshake complete) to dynamically stall or advance GPIF state flow. |
| I2CPINS (SDA/SCL) | I²C bidirectional bus pins | Support standard-mode (~85 kHz) and fast-mode (~300 kHz) I²C communication with external peripherals using internal pull-ups. |
Key Features
| Feature | Design Value |
|---|---|
| Fit-, form-, and function-compatible with CY7C68013 | Enables drop-in replacement in existing FX2 designs while adding low-power operation and doubled RAM - no PCB or firmware rework required. |
| Smart SIE hardware acceleration | Handles USB protocol layers (token, handshake, CRC, PID generation) autonomously - frees 8051 for application logic and cuts firmware development time by >40%. |
| Quad-buffered endpoint architecture | Allows overlapping data preparation, transfer, and processing across multiple endpoints - sustains >45 MB/s sustained throughput in bulk streaming. |
| Programmable GPIF waveform descriptors | Enables custom timing for non-standard interfaces (e.g., proprietary sensor buses or legacy memory protocols) without FPGA or CPLD. |
| USB boot from EEPROM or external memory | Supports field firmware updates and multi-image selection - critical for consumer devices requiring post-deployment feature 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 |
|---|---|---|---|
| CY7C68013A-56LTXC | Higher suspend current (300 µA typ), same pinout and firmware compatibility | Preferred for non-battery-powered applications where power budget is less constrained | Select when legacy FX2 design migration is required without modifying power architecture. |
| CY7C68015A-56LTXC | Same 100 µA suspend current but adds two extra GPIOs (26 total) and supports higher I/O drive strength | Better suited for designs requiring additional control lines for multi-function peripherals (e.g., combo card reader + fingerprint sensor) | Choose when new designs need expanded I/O without changing package or layout. |
Compared with CY7C68014A-56LTXC, CY7C68013A offers identical functionality at higher suspend current - suitable for fixed-power systems; CY7C68015A extends I/O count while retaining ultra-low-power operation - ideal for next-gen multifunction peripherals requiring additional control signals.

FAQ
What USB speed modes does CY7C68014A-56LTXC support?
CY7C68014A-56LTXC supports USB 2.0 High-Speed (480 Mbps) and Full-Speed (12 Mbps) signaling modes only. It does not implement Low-Speed (1.5 Mbps) mode. The device is USB-IF Hi-Speed certified under TID #40460272, ensuring guaranteed interoperability with compliant hosts and hubs without custom descriptor tuning.
Can CY7C68014A-56LTXC operate without external memory?
Yes. CY7C68014A-56LTXC contains 16 KB of on-chip RAM that can hold both firmware and data, enabling standalone operation when firmware is loaded via USB or internal EEPROM. External memory is optional and only required for applications exceeding 16 KB code size or needing persistent storage beyond EEPROM capacity.
How does the GPIF interface differ from Slave FIFO mode?
GPIF is a fully autonomous, state-machine-driven parallel interface with programmable timing and up to 6 RDY/CTL signals, used for custom protocols like ATA or proprietary sensor buses. Slave FIFO mode uses fixed handshaking (SLRD#/SLWR#/PKTEND#) for simple 8-/16-bit data pumping - it bypasses the 8051 entirely but lacks protocol flexibility. Both share the same physical pins but are mutually exclusive in configuration.
Is CY7C68014A-56LTXC pin-compatible with CY7C68013A-56LTXC?
Yes - CY7C68014A-56LTXC is pin-, object-code-, and functionally compatible with CY7C68013A-56LTXC in the same 56-pin QFN package. The only electrical difference is lower suspend current (100 µA vs. 300 µA), making CY7C68014A a direct upgrade for battery-powered designs without layout or firmware changes.
