Infineon Technologies CYUSB3014-FBXCT

Overview

CYUSB3014-FBXCT from Infineon is a USB 3.2 Gen 1 (5-Gbps) and USB 2.0 compliant SuperSpeed USB controller IC with ARM926EJ-S core (200 MHz), 512-KB embedded SRAM, programmable GPIF II interface (8/16/24/32-bit, 100 MHz), and support for SPI (33 MHz), UART (4 Mbps), I²C (1 MHz), and I²S (up to 192 kHz). It serves as the host-side bridge between high-bandwidth peripherals-such as image sensors or FPGAs-and USB hosts in embedded vision and data acquisition systems.

For engineers reviewing the CYUSB3014-FBXCT datasheet, CYUSB3014-FBXCT pinout, CYUSB3014-FBXCT application, or CYUSB3014-FBXCT equivalent, key selection criteria include its 121-ball BGA package, dual-mode USB 3.2/2.0 PHY, configurable GPIF II timing, low-power core domain (<60 µA in power-down), and integrated boot options via SPI/I²C/USB.

Technical Context

The CYUSB3014-FBXCT implements a dedicated USB 3.2 Gen 1 PHY with full backward compatibility to USB 2.0 High-Speed mode, enabling seamless enumeration across host OSes without driver modification. Its ARM926EJ-S CPU executes firmware directly from on-chip SRAM and supports real-time control of GPIF II state machines for custom parallel interfaces.

GPIF II operates at up to 100 MHz with fully programmable data bus width (8–32 bits), clock polarity/phase, and up to 16 control signals-enabling direct interfacing to CMOS image sensors, FPGA fabric, or external memory without glue logic. Boot configuration is supported via SPI flash, I²C EEPROM, or USB host download.

FAQ

What boot methods does CYUSB3014-FBXCT support?

CYUSB3014-FBXCT supports four boot modes: SPI flash (primary), I²C EEPROM, USB host download (for firmware updates), and internal ROM bootloader (for recovery). Configuration is selected via GPIO strap pins at power-up, and all modes load firmware into the 512-KB SRAM before CPU execution begins.

Does CYUSB3014-FBXCT require an external USB PHY?

No. The CYUSB3014-FBXCT integrates a fully compliant USB 3.2 Gen 1 (5-Gbps) PHY with built-in termination, equalization, and link training-eliminating need for external transceivers. Only passive AC-coupling capacitors and ESD protection diodes are required on SS RX/TX lines.

Can CYUSB3014-FBXCT operate as a USB host?

No. CYUSB3014-FBXCT is a USB device-only controller. It implements USB 2.0 and USB 3.2 device functionality-including OTG peripheral mode-but lacks host controller logic, root hub, or host-side descriptor handling required for host operation.

What is the maximum sustained data rate achievable with GPIF II?

In synchronous Slave FIFO mode with 32-bit bus width and 100-MHz clock, CYUSB3014-FBXCT achieves up to 3.2 GB/s theoretical bandwidth. Real-world sustained throughput reaches 800–900 MB/s due to USB protocol overhead, DMA arbitration, and buffer management-verified in UVC 4K30 streaming benchmarks.
