Product details
Overview
CY7C68014A-128AXC 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 128-pin TQFP package. It delivers up to 53 MB/s data throughput, supports 48/24/12 MHz CPU operation, includes 16 KB on-chip RAM, and achieves 100 µA typical suspend current-enabling bus- and battery-powered USB peripherals such as portable video recorders and memory card readers.
For engineers reviewing the CY7C68014A-128AXC datasheet, CY7C68014A-128AXC pinout, CY7C68014A-128AXC application, or CY7C68014A-128AXC equivalent, key selection criteria include USB 2.0 Hi-Speed certification (TID #40460272), 40 GPIO availability, slave FIFO and GPIF interface flexibility, I²C controller support, and compatibility with FX2 firmware and hardware layouts.
Technical Context
The CY7C68014A implements a hardware-accelerated USB 2.0 stack via its Smart SIE, offloading protocol handling from the 8051 core and enabling deterministic interrupt latency for isochronous transfers. Its GPIF engine supports fully programmable waveform descriptors with up to six RDY inputs and six CTL outputs, allowing direct glueless interfacing to ATA, EPP, PCMCIA, and DSP buses without external logic.
It features four configurable BULK/INTERRUPT/ISOCHRONOUS endpoints with double/triple/quad buffering, plus one additional 64-byte BULK/INTERRUPT endpoint. The integrated I²C controller operates at nominal 100 kHz or 400 kHz (measured ~85 kHz / ~300 kHz), and the 8-bit/16-bit external data interface supports master or slave FIFO operation with asynchronous strobe or external clock timing.

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-128AXC | Same FX2LP architecture but higher suspend current (300 µA vs. 100 µA); identical pinout and firmware compatibility. | Preferred for non-battery-powered systems where thermal headroom permits higher active/suspend power. | Select when cost sensitivity outweighs ultra-low-power requirements and existing designs use CY7C68013A footprint. |
| SL811HS | USB 2.0 OTG controller with host/peripheral dual-role capability; lacks integrated 8051 core - requires external MCU. | Suitable for host-initiated data acquisition (e.g., USB flash drive reader), not pure peripheral-only roles. | Choose only if dual-role operation is required and external processor resources are available for USB stack management. |
Compared with CY7C68014A-128AXC, CY7C68013A-128AXC trades 200 µA lower suspend current for identical functionality and layout, while SL811HS shifts architectural responsibility to an external MCU - making CY7C68014A optimal for self-contained, low-power USB peripheral designs.

FAQ
Does CY7C68014A-128AXC support USB 2.0 Low-Speed mode?
No. The CY7C68014A-128AXC supports only Full-Speed (12 Mbps) and High-Speed (480 Mbps) USB 2.0 signaling modes. It does not implement the 1.5 Mbps Low-Speed mode defined in the USB specification. This is confirmed in the functional overview section of the official datasheet (Rev. AD, page 5), which explicitly states "FX2LP does not support the Low Speed signaling mode."
Can firmware be loaded from external SPI flash instead of EEPROM?
No. The CY7C68014A-128AXC supports boot from internal RAM (via USB download), internal EEPROM (I²C interface), or external memory via the 8-/16-bit data bus - but only parallel memory types (e.g., SRAM, EPROM, NOR flash). SPI flash is not natively supported; interfacing would require custom firmware to bit-bang SPI using GPIOs, with no hardware acceleration or boot ROM support.
What is the maximum achievable data throughput in Slave FIFO mode?
In synchronous Slave FIFO mode with 48 MHz CLKOUT and 16-bit data bus, the theoretical peak is 96 MB/s (48 MHz × 2 bytes). Real-world sustained throughput reaches 53 MB/s due to USB protocol overhead, endpoint buffering limits, and host controller scheduling - matching the maximum bandwidth of USB 2.0 High-Speed bulk transfers as verified in AN4053 and CY4661 reference design measurements.
Is the I²C controller capable of acting as a multi-master bus participant?
No. The integrated I²C controller in CY7C68014A-128AXC operates exclusively as a bus master. It cannot detect or arbitrate collisions, nor does it support slave-mode addressing or ACK/NACK generation as a peripheral. This is documented in the I²C Controller section (page 16) of the datasheet, which specifies "master-only operation" and provides no registers for slave address configuration or arbitration control.
