Infineon Technologies CYUSB3014-BZXIT

Overview

CYUSB3014-BZXIT from Infineon is a USB 3.2 Gen 1 (5 Gbps) and USB 2.0 compliant SuperSpeed USB controller with ARM926EJ-S core (200 MHz), 512 KB 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-BZXIT datasheet, CYUSB3014-BZXIT pinout, CYUSB3014-BZXIT application, or CYUSB3014-BZXIT equivalent, key selection criteria include GPIF II timing configurability, dual-speed USB compliance, low-power core state (<60 µA), independent I/O voltage domains (1.2–3.3 V), and BGA-121 package compatibility with high-density PCB layouts.

Technical Context

The CYUSB3014-BZXIT implements a dedicated USB 3.2 Gen 1 PHY with full backward compatibility to USB 2.0, enabling simultaneous SuperSpeed and High-Speed device enumeration. Its ARM926EJ-S CPU executes firmware directly from on-chip SRAM and supports real-time USB video class (UVC) streaming via configurable GPIF II slave FIFO interfaces.

GPIF II operates at up to 100 MHz with fully programmable state machines, supporting synchronous/asynchronous SRAM, Slave FIFO, and custom protocols. Boot options include SPI Flash, I²C EEPROM, or USB-hosted firmware download-enabling field-upgradable operation without external programming hardware.

FAQ

Does CYUSB3014-BZXIT support USB On-The-Go (OTG) functionality?

Yes, it supports HS-OTG host and peripheral modes per USB OTG Supplement v2.0. The device can dynamically switch roles using VBUS detection and ID pin sensing, enabling single-cable connectivity between cameras and mobile hosts without hub dependency. Firmware-controlled re-enumeration allows class switching (e.g., UVC to MSC) during operation.

What development tools are required to configure the GPIF II interface?

The Cypress-provided GPIF II Designer tool (included in EZ-USB FX3 SDK) is mandatory. It generates synthesizable HDL-like state machine code from graphical pin assignments, timing parameters, and bus-width selections. Output integrates directly into FX3 firmware build; no external synthesis tools or FPGA IDEs are needed.

Can CYUSB3014-BZXIT operate without external memory?

Yes - all firmware and data buffers execute from its 512 KB on-chip SRAM. No external RAM or Flash is required for basic UVC or bulk-transfer operation. External SPI Flash is optional for non-volatile firmware storage; I²C EEPROM may be used for device descriptors but is not mandatory.

Is the 19.2 MHz crystal input mandatory for USB 3.2 Gen 1 operation?

No - while 19.2 MHz is the reference clock for USB SOF generation and recommended for I²S synchronization, the device accepts 26 MHz, 38.4 MHz, or 52 MHz inputs. All supported frequencies derive exact 125 MHz USB reference clocks via internal PLL; 19.2 MHz remains preferred for lowest jitter in video timing-critical applications.
