Product details
Overview
CY7C68014A-100AXC from Infineon Technologies (formerly Cypress) is a USB 2.0 high-speed peripheral controller integrating an enhanced 8051 microprocessor, USB 2.0 transceiver, smart serial interface engine (SIE), and general programmable interface (GPIF) in a single 100-pin TQFP package. It delivers up to 53 MB/s data throughput, supports 48-MHz CPU operation, includes 16 KB on-chip RAM, and draws only 100 µA typical current in suspend mode-making it ideal for battery-powered USB peripherals such as portable video recorders and memory card readers.
For engineers reviewing the CY7C68014A-100AXC datasheet, CY7C68014A-100AXC pinout, CY7C68014A-100AXC application, or CY7C68014A-100AXC equivalent, key selection criteria include USB 2.0 Hi-Speed certification (TID #40460272), GPIF waveform programmability, dual USART support, 8/16-bit external data interface capability, and compatibility with FX2 firmware and hardware layouts.
Technical Context
The CY7C68014A implements a dedicated USB 2.0 PHY with integrated transceiver and hardware-accelerated SIE that offloads protocol handling from the 8051 core, enabling full USB enumeration and control transfer management without firmware intervention. Its PLL generates 480 MHz for the transceiver while deriving 48/24/12 MHz clocks for the CPU via programmable dividers.
GPIF operates as an autonomous state-machine-driven interface with configurable RDY/CTL signals, supporting synchronous/asynchronous 8- or 16-bit bus protocols-including ATA, EPP, and PCMCIA-without external glue logic. Four internal FIFOs (up to 4 kB total) and endpoint buffering options (double/triple/quad) enable deterministic isochronous and bulk transfers.

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-100AXC | Higher suspend current (300 µA typ), same pinout and firmware compatibility | Preferred for non-battery-powered desktop peripherals where power is not constrained | Select when lower-cost qualification path is needed and battery life is not critical |
| SL811HS | USB 2.0 host/peripheral dual-role controller; no integrated 8051; requires external microcontroller | Used in embedded host applications (e.g., USB flash drive controllers), not pure peripheral mode | Choose only if host-mode capability is required and external MCU resources are available |
Compared with CY7C68014A-100AXC, the CY7C68013A offers identical footprint and firmware but higher suspend current-suitable for AC-powered designs-while SL811HS provides host functionality at the cost of added system complexity and no native microcontroller.

FAQ
What boot methods does the CY7C68014A-100AXC support?
The CY7C68014A-100AXC supports three boot sources: internal RAM loaded via USB (default), internal RAM loaded from external I²C EEPROM (address 0x50), or external memory mapped through the 8/16-bit data bus. Boot mode is selected by strapping pins (e.g., IFCLK, PKTEND) at power-on reset, and no external ROM is required for basic operation.
Does the CY7C68014A-100AXC require an external crystal?
Yes-it requires a 24 MHz ±100 ppm parallel-resonant fundamental-mode crystal with 12 pF load capacitance. The on-chip PLL uses this reference to generate the 480 MHz USB PHY clock and derive 48/24/12 MHz CPU clocks. No internal RC oscillator is provided; crystal omission prevents USB enumeration.
Can the GPIF interface be reconfigured dynamically during runtime?
Yes-the GPIF waveform descriptors are stored in on-chip RAM and can be rewritten by the 8051 firmware at runtime. This allows dynamic switching between different bus protocols (e.g., ATA vs. EPP) without resetting the device, provided descriptor tables are preloaded and validated for timing compliance.
Is the CY7C68014A-100AXC pin-compatible with the 128-pin TQFP variant?
No-CY7C68014A-100AXC uses a 100-pin TQFP package with 40 GPIOs, while the 128-pin TQFP variant (e.g., CY7C68014A-128AXC) adds 8 extra GPIOs and supports external memory expansion. Pin mapping differs significantly; direct substitution requires PCB redesign and firmware I/O remapping.
