Product details
Overview
CY7C68013A-56LTXCT 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 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 operation, includes 16 KB on-chip RAM, and features four configurable BULK/INTERRUPT/ISOCHRONOUS endpoints with double/triple/quad buffering.
For engineers reviewing the CY7C68013A-56LTXCT datasheet, CY7C68013A-56LTXCT pinout, CY7C68013A-56LTXCT application, or CY7C68013A-56LTXCT equivalent, key selection criteria include GPIF waveform programmability, suspend current of 300 µA (typ), 8-bit/16-bit external data interface support, I²C controller operation at 100/400 kHz, and compatibility with FX2 firmware and hardware layouts.
Technical Context
The CY7C68013A implements a hardware-accelerated USB 2.0 stack via its Smart SIE, offloading protocol handling from the 8051 core and enabling deterministic endpoint management. Its GPIF operates independently of the CPU, supporting user-defined parallel waveforms with up to six RDY inputs and six CTL outputs for precise timing control of external ASICs, DSPs, or memory interfaces.
USB enumeration and data transfers are managed through dedicated FIFOs and endpoint buffers, with separate setup/data buffers for CONTROL transfers and automatic 8-/16-bit bus width conversion. The device boots from internal RAM (loaded via USB or EEPROM) and supports slave FIFO, master FIFO, and GPIF modes-each with distinct clocking, strobe, and handshaking requirements verified in AC timing tables.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB peripheral controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C68013A-100AXC | 100-pin TQFP package; 40 GPIOs vs. 24; same core, RAM, and USB functionality. | Requires larger PCB footprint; enables more complex GPIF designs with additional RDY/CTL lines and external memory interface. | Select when >24 GPIOs or external 16-bit memory interface is required; otherwise, 56LTXCT offers lower cost and smaller area. |
| CY7C68014A-56LTXC | Identical pinout and package; 100 µA typical suspend current vs. 300 µA; optimized for battery-powered use. | Better suited for portable devices with strict quiescent power budgets; shares same firmware and hardware layout. | Choose CY7C68014A for battery operation; CY7C68013A remains optimal for mains-powered or thermally constrained designs. |
Compared with CY7C68013A-100AXC, the -56LTXCT saves board space and cost while retaining full USB 2.0 performance; versus CY7C68014A-56LTXC, it trades 200 µA higher suspend current for broader voltage margin and simplified power sequencing in non-battery systems.

FAQ
Is CY7C68013A-56LTXCT pin-compatible with the original CY7C68013?
Yes - the CY7C68013A-56LTXCT is fit-, form-, and function-compatible with the CY7C68013 FX2 in the 56-pin package. Pin assignments, register map, and firmware binary are identical; only internal power optimization differs. No PCB redesign is needed for migration from FX2 to FX2LP.
Does CY7C68013A-56LTXCT support USB 2.0 High-Speed enumeration without external components?
Yes - the integrated USB 2.0 transceiver meets Hi-Speed electrical specifications and requires only standard USB-series resistors (15 kΩ pull-downs on D+/D−) and a 24 MHz crystal. No external PHY, level shifters, or termination ICs are needed for full 480 Mbps operation.
Can the GPIF be reconfigured dynamically during runtime?
Yes - GPIF waveform descriptors can be loaded into the 4096-word descriptor RAM via the 8051 while the device is operating. This allows real-time adaptation to different peripheral protocols (e.g., switching between SRAM and ATA timing) without resetting the USB connection.
What boot methods does CY7C68013A-56LTXCT support?
It supports three boot modes: (1) USB download into internal RAM (default), (2) EEPROM load at power-on (using I²C address 0x50), and (3) external memory fetch via 8-/16-bit bus (not available in 56-pin package). No external ROM or flash is required for basic operation.
