Infineon Technologies CY7C68013A-56PVXI

Overview

CY7C68013A-56PVXI 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 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 CY7C68013A-56PVXI datasheet, CY7C68013A-56PVXI pinout, CY7C68013A-56PVXI application, or CY7C68013A-56PVXI equivalent, key selection criteria include suspend current (300 µA typ), GPIF waveform programmability, endpoint buffering options (double/triple/quad), and compatibility with FX2 firmware and hardware layouts.

Technical Context

The device implements a hardware-accelerated USB 2.0 stack via its Smart SIE, offloading protocol handling from the 8051 core and enabling deterministic interrupt response for isochronous transfers. Its GPIF operates independently of the CPU, supporting fully configurable timing waveforms for direct glueless interfacing to ATA, EPP, PCMCIA, and DSP buses.

USB enumeration and configuration are handled in firmware loaded into internal RAM via USB or EEPROM; the chip supports four programmable endpoints (BULK/INT/ISO) plus one additional 64-byte BULK/INT endpoint, with separate setup/data buffers for CONTROL transfers and integrated I²C controller (85 kHz / 300 kHz actual clock at 100/400 kHz nominal settings).

FAQ

What firmware development tools are officially supported for CY7C68013A-56PVXI?

Infineon provides the EZ-USB FX2LP Development Kit (CY3684), GPIF Designer GUI tool, and the EZ-USB FX2LP Technical Reference Manual. Firmware is written in C or assembly for the enhanced 8051 core using Keil µVision or SDCC, with USB descriptors configured via EZ-USB Control Panel or custom host utilities.

Does CY7C68013A-56PVXI require an external crystal, and what are the specifications?

Yes-it requires a 24 MHz ±100 ppm parallel-resonant fundamental-mode crystal with 500 µW drive level and 12 pF (±5%) load capacitance. The on-chip PLL multiplies this to 480 MHz for the USB PHY; the 8051 clock is derived by integer division (12/24/48 MHz selectable via CPUCS register).

Can CY7C68013A-56PVXI operate in self-powered mode with external 5 V?

No-it operates exclusively at 3.3 V core voltage. While its I/O pins are 5-V tolerant, the VCC pin must be supplied with 3.3 V ±10%. External 5 V may be used only for VBUS sensing or to power external circuitry; a dedicated 3.3 V LDO regulator is required for VCC.

How does the Slave FIFO interface differ from GPIF in practical implementation?

Slave FIFO mode uses fixed, preconfigured timing (e.g., SLRD#/SLWR# strobes) for simple 8-/16-bit data transfers controlled by the external master; GPIF mode replaces that master with programmable state machines and waveform descriptors, enabling complex, variable-width protocols like ATA or UTOPIA without CPU involvement or external logic.
