Product details
Overview
CY7C68015A-56LTXC from Infineon Technologies (formerly Cypress Semiconductor) is a high-speed USB 2.0 peripheral controller integrating a USB 2.0 transceiver, Smart Serial Interface Engine (SIE), enhanced 8051 microcontroller, and General Programmable Interface (GPIF) in a single 56-pin QFN package. It delivers up to 53 MB/s data throughput, supports 48/24/12 MHz CPU clocking, includes 16 KB on-chip RAM, and operates at 3.3 V with 5-V tolerant I/O-enabling bus-powered video capture and legacy interface bridge applications.
For engineers reviewing the CY7C68015A-56LTXC datasheet, CY7C68015A-56LTXC pinout, CY7C68015A-56LTXC application, or CY7C68015A-56LTXC equivalent, key selection criteria include its USB 2.0 Hi-Speed certification (TID #40460272), 26 GPIO count in 56-pin QFN, suspend current of 300 µA (typ), dual USARTs, and GPIF waveform programmability for glueless ASIC/DSP interfacing.
Technical Context
The CY7C68015A 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 PLL generates 480 MHz for the transceiver while deriving 48/24/12 MHz clocks for the CPU using four clocks per instruction cycle.
GPIF operates as an autonomous state-machine-based interface engine supporting 8-/16-bit synchronous/asynchronous buses, up to six RDY inputs and six CTL outputs, and configurable waveform descriptors-enabling direct connection to ATA, EPP, PCMCIA, and FPGA peripherals without external logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Speed | Hi-Speed (480 Mbps) and Full-Speed (12 Mbps); no Low-Speed support-enables real-time video streaming and high-bandwidth peripheral bridging. |
| CPU Core | Enhanced 8051 running at 48/24/12 MHz; four clocks/instruction cycle-delivers deterministic timing for USB control transfers and firmware-driven endpoint management. |
| On-chip RAM | 16 KB code/data RAM-supports full firmware execution without external memory, reducing BOM cost and PCB footprint. |
| Endpoints | Four programmable BULK/INTERRUPT/ISOCHRONOUS endpoints + one additional 64-byte BULK/INTERRUPT endpoint-enables concurrent audio/video/control channel handling. |
| I/O Count | 26 GPIOs in 56-pin QFN package-provides sufficient signals for GPIF bus control, I²C, USARTs, and custom peripheral interfacing within compact industrial enclosures. |
| Power Supply | 3.3 V operation with 5-V tolerant inputs-allows direct interfacing with legacy 5-V logic and simplifies level-shifting in mixed-voltage systems. |
| Suspend Current | 300 µA (typ) at 3.3 V-meets USB specification for non-battery-powered devices, enabling low-power idle states in always-on embedded gateways. |
Pinout & Package
Package: 56-pin QFN (7 mm × 7 mm, 0.5 mm pitch), Pb-free, RoHS-compliant, industrial temperature grade (–40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PA0–PA7 | GPIF Data Bus (Lower) | 8-bit bidirectional data path for slave FIFO or GPIF master mode; supports asynchronous strobes or synchronous clocking. |
| PB0–PB7 | GPIF Data Bus (Upper) | Enables 16-bit wide data transfers when used with PA0–PA7; required for high-throughput ATA or UTOPIA interface implementations. |
| PC0–PC7 | GPIF Control & Ready | Configurable as 6 CTL outputs and 6 RDY inputs-defines handshake timing for custom peripheral protocols without CPU intervention. |
| D+ / D− | USB 2.0 Differential Pair | Integrated transceiver with on-die termination-eliminates need for external USB PHY and reduces EMI-sensitive routing complexity. |
| CLKOUT | CPU Clock Output | Three-stateable, invertible 12/24/48 MHz output-synchronizes external logic or ADC sampling to the 8051 core clock. |
| I2C_SDA / I2C_SCL | I²C Bus Interface | Open-drain pins supporting 100 kHz or 400 kHz operation-enables EEPROM configuration loading or sensor communication without GPIO bit-banging. |
Key Features
| Feature | Design Value |
|---|---|
| Smart SIE Hardware Acceleration | Handles USB enumeration, SETUP packet parsing, and CRC generation autonomously-reduces 8051 firmware overhead by >70% versus software-only stacks. |
| GPIF Waveform Programmability | State-machine descriptors define custom read/write strobes, address latching, and handshaking-enables zero-latency interfacing to FPGAs or ASICs without glue logic. |
| Dual USARTs | Independent serial ports with baud rate generators-supports simultaneous debug console output and RS-232/RS-485 peripheral control in field-deployed instrumentation. |
| Four Integrated FIFOs | Configurable as double/triple/quad buffering per endpoint-absorbs USB packet jitter and prevents data loss during burst transfers from cameras or ADCs. |
| USB Boot Options | Firmware loaded from internal RAM (via USB), external EEPROM, or external memory-enables field-upgradable behavior and secure boot from encrypted flash. |
Applications
| Portable Video Capture | Legacy Interface Bridge |
|---|---|

Use Scenario: Fingerprint authentication module integrated into USB keyboard or smart card reader. IC Role / Device Role / Timing Role: Secure USB peripheral managing biometric sensor I²C communication, cryptographic key storage in EEPROM, and HID report generation. Use Value: Leverages built-in I²C controller (100/400 kHz) and 3.3-V 5-V tolerant I/O to interface directly with capacitive fingerprint sensors-reducing component count and attack surface. |
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 | Same FX2LP architecture, but 24 GPIOs (vs. 26), no VBUS detection pin, identical 56-pin QFN footprint | Limited GPIO count restricts complex GPIF waveforms requiring >6 RDY/CTL signals | Select when existing layout uses CY7C68013A and only minor firmware updates are needed. |
| AN2131QC | Legacy FX1 architecture; no Smart SIE, no GPIF, 8 KB RAM, 12-MHz fixed CPU clock | Cannot support Hi-Speed USB or isochronous transfers; requires full firmware USB stack implementation | Choose only for cost-sensitive, low-bandwidth applications where USB 2.0 compliance is not required. |
Compared with CY7C68013A-56LTXC, the CY7C68015A-56LTXC provides two additional GPIOs for expanded GPIF control and native VBUS sensing-critical for self-powered hub designs. Versus AN2131QC, it delivers hardware USB acceleration and 2× RAM, reducing firmware development time by ~60% for Hi-Speed peripheral projects.

FAQ
Is CY7C68015A-56LTXC pin-compatible with CY7C68013A-56LTXC?
Yes, CY7C68015A-56LTXC is pin-compatible with CY7C68013A-56LTXC in the 56-pin QFN package. Both share identical power, USB, GPIF, and I/O pin assignments. The CY7C68015A adds two dedicated GPIOs (PORTC[6:7]) not present on CY7C68013A, but these are unconnected in legacy footprints-enabling drop-in replacement with optional firmware extension.
What USB 2.0 compliance certifications does this device hold?
CY7C68015A-56LTXC is USB IF Hi-Speed certified with TID #40460272. It fully complies with USB Specification Revision 2.0 for both High-Speed (480 Mbps) and Full-Speed (12 Mbps) signaling. It does not support Low-Speed (1.5 Mbps) mode. Certification covers electrical signaling, protocol handling, and enumeration behavior under defined test conditions.
Can the onboard 8051 execute firmware from external memory?
No-the CY7C68015A-56LTXC lacks external memory interface pins in the 56-pin QFN package. Firmware must be loaded into its 16 KB on-chip RAM via USB download, EEPROM boot, or pre-programmed internal ROM (not user-accessible). External memory execution is only supported on 100- and 128-pin TQFP variants with dedicated address/data bus pins.
Does this device support USB suspend/resume with wake-on-USB events?
Yes, CY7C68015A-56LTXC supports USB suspend mode with typical current draw of 300 µA and can resume via USB bus activity (e.g., SET_FEATURE(DEVICE_REMOTE_WAKEUP)). It also supports wake-from-suspend via external interrupt pins (INT0/INT1) or GPIF RDY transitions-enabling low-power monitoring of attached peripherals without host polling.
