Infineon Technologies CYUSB3014-FBXIT

Overview

CYUSB3014-FBXIT from Infineon is a USB 3.2 Gen 1 (5 Gbps) and USB 2.0 programmable SuperSpeed USB controller with ARM926EJ-S CPU (200 MHz), 512 KB SRAM, 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 a high-bandwidth bridge between USB hosts and external image sensors, FPGAs, or data acquisition peripherals in embedded vision systems.

For engineers reviewing the CYUSB3014-FBXIT datasheet, CYUSB3014-FBXIT pinout, CYUSB3014-FBXIT application, or CYUSB3014-FBXIT equivalent, key selection criteria include USB 3.2 Gen 1 PHY compliance (TID #340800007), GPIF II configurability for custom parallel interfaces, low-power core mode (<60 µA), independent 1.2 V core / 1.8–3.3 V I/O power domains, and BGA-121 (10 × 10 mm, 0.8 mm pitch) package compatibility with high-density PCB layouts.

Technical Context

The CYUSB3014-FBXIT implements a dual-mode USB controller with fully compliant USB 3.2 Gen 1 (5 Gbps) and USB 2.0 physical layers, including HS-OTG host/peripheral functionality per OTG Supplement v2.0. Its ARM926EJ-S CPU executes firmware directly from on-chip 512 KB SRAM and supports real-time control of 32 physical endpoints.

GPIF II operates at up to 100 MHz with programmable bus widths (8/16/24/32-bit) and 16 configurable control signals, enabling deterministic timing for synchronous/asynchronous slave FIFO, SRAM, or custom logic interfacing - critical for pixel-accurate video streaming from CMOS sensors or FPGA-based frame buffers.

FAQ

Does CYUSB3014-FBXIT require an external crystal?

Yes - it supports 19.2, 26, 38.4, or 52 MHz crystal or oscillator inputs. A 19.2 MHz crystal is recommended for USB SOF timing accuracy and compatibility with common image sensor reference clocks. The device integrates internal PLLs to generate required USB and CPU clocks from this input.

Can CYUSB3014-FBXIT operate as a USB host?

Yes - it implements USB On-The-Go (OTG) Supplement v2.0, enabling HS-OTG host mode to enumerate and control USB peripherals such as flash drives, HID devices, or serial adapters. Host mode requires appropriate VBUS control circuitry and firmware-level USB host stack integration.

What development tools are included with the EZ-USB FX3 SDK?

The official Infineon EZ-USB FX3 SDK includes ThreadX RTOS framework, firmware examples for all I/O modules (SPI, UART, I²C, I²S, GPIF II), Visual Studio host applications in C++/C#, GPIF II Designer GUI tool, and USB descriptor configuration utilities - all provided royalty-free for commercial use.

Is JTAG debugging supported on CYUSB3014-FBXIT?

Yes - the device features a dedicated 5-pin JTAG interface (TCK, TMS, TDI, TDO, TRST#) compliant with IEEE 1149.1, enabling full boundary-scan testing, CPU core debugging, and firmware flash programming using standard tools like Segger J-Link or Infineon's MiniProg3.
