Infineon Technologies CY7C68013A-56PVXCT

Overview

CY7C68013A-56PVXCT 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-MHz CPU operation, includes 16 KB on-chip RAM, and features four programmable BULK/INTERRUPT/ISOCHRONOUS endpoints with double/triple/quad buffering - enabling bus-powered video capture and firmware-upgradable USB peripherals.

For engineers reviewing the CY7C68013A-56PVXCT datasheet, CY7C68013A-56PVXCT pinout, CY7C68013A-56PVXCT application, or CY7C68013A-56PVXCT equivalent, key selection criteria include USB 2.0 Hi-Speed certification (TID #40460272), 3.3-V operation with 5-V tolerant I/O, suspend current of 300 µA (typ), GPIF waveform programmability, and compatibility with FX2 legacy firmware and hardware layouts.

Technical Context

The device 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 CPU intervention. Its Smart SIE handles token, handshake, and error recovery at both full-speed (12 Mbps) and high-speed (480 Mbps) modes - excluding low-speed (1.5 Mbps).

GPIF operates as an autonomous state-machine-based interface engine supporting 8-/16-bit synchronous/asynchronous bus protocols, with six RDY inputs and six CTL outputs for precise timing control. The 8051 core runs at 12/24/48 MHz (four clocks per instruction cycle), includes two USARTs, three timers, expanded interrupts, and dual data pointers - all accessible via standard Keil C51 toolchain.

FAQ

Does CY7C68013A-56PVXCT require an external crystal?

Yes - it requires a 24-MHz parallel-resonant fundamental-mode crystal with ±100 ppm tolerance, 500-µW drive level, and 12-pF load capacitance. The on-chip PLL multiplies this to 480 MHz for the USB PHY, while internal dividers generate the 12/24/48 MHz 8051 clock. No internal RC oscillator is provided.

Can CY7C68013A-56PVXCT operate in low-speed USB mode (1.5 Mbps)?

No - the device supports only full-speed (12 Mbps) and high-speed (480 Mbps) USB signaling. It lacks hardware support for low-speed mode, and its USB transceiver is not compliant with the 1.5 Mbps signaling requirements defined in USB 2.0 Specification Section 7.1.3.

Is GPIF configuration stored permanently in the device?

No - GPIF waveform descriptors reside in on-chip RAM and must be loaded by firmware at startup. They are not stored in non-volatile memory. Descriptors can be updated dynamically during runtime, enabling adaptive interface behavior without reset.

What is the maximum sustained data rate achievable with CY7C68013A-56PVXCT?

Up to 53 MB/s (424 Mbps) in bulk transfer mode using quad-buffered endpoints and optimized firmware - representing >90% of theoretical USB 2.0 high-speed bandwidth. Real-world throughput depends on host driver efficiency, endpoint buffer size, and GPIF timing margins.
