Infineon Technologies CYUSB3017-BZXIT

Overview

CYUSB3017-BZXIT from Infineon Technologies (formerly Cypress Semiconductor) is a configurable SuperSpeed USB 3.2 Gen 1 peripheral controller with integrated ARM926EJ-S CPU, USB 3.2/2.0 PHYs, and General Configurable Interface supporting UVC/UAC protocols. It delivers up to 375 MBps data throughput, features 512 KB on-chip SRAM, and operates at 200 MHz core frequency. It targets USB video capture systems requiring real-time HDMI or image sensor bridging.

For engineers reviewing the CYUSB3017-BZXIT datasheet, CYUSB3017-BZXIT pinout, CYUSB3017-BZXIT application, or CYUSB3017-BZXIT equivalent, key selection criteria include UVC protocol support, 100-MHz parallel interface timing, 1.2-V core voltage domain, and BGA-121 package compatibility for high-density camera interface designs.

Technical Context

The CYUSB3017-BZXIT implements a dual-mode USB stack compliant with USB 3.2 Gen 1 (5 Gbps) and USB 2.0, with hardware-assisted re-enumeration enabling dynamic device identity switching. Its ARM926EJ-S CPU executes firmware directly from 512 KB embedded SRAM and manages DMA transfers between the General Configurable Interface and USB endpoints.

It supports three physical USB endpoints and integrates dedicated UVC/UAC descriptor handling logic, I2C (100/400/1000 kHz), SPI boot flash interface, and independent power domains (1.2 V core, 1.8–3.3 V I/O). Clock input options include 19.2, 26, 38.4, and 52 MHz, with crystal support at 19.2 MHz.

FAQ

What USB classes does CYUSB3017-BZXIT natively support without external firmware modification?

CYUSB3017-BZXIT natively supports USB Video Class (UVC) and USB Audio Class (UAC) via built-in hardware protocol engines and factory-programmed descriptor tables. It enumerates as a standard UVC device on Windows and macOS without custom drivers, supporting resolutions up to 4K30 and frame rates up to 60 fps with YUV422 or MJPEG encoding paths.

Does CYUSB3017-BZXIT require an external crystal, and what frequencies are supported?

Yes, CYUSB3017-BZXIT requires a 19.2-MHz fundamental-mode crystal connected to the XTAL_IN/XTAL_OUT pins for primary clocking. It also accepts 26-MHz, 38.4-MHz, and 52-MHz clock inputs via the CLKIN pin. The 19.2-MHz crystal option enables lowest jitter for USB 3.2 Gen 1 link stability and precise video timing synchronization.

Can CYUSB3017-BZXIT interface directly with MIPI CSI-2 image sensors?

No, CYUSB3017-BZXIT does not support native MIPI CSI-2 signaling. It requires an external bridge IC (e.g., ON Semiconductor AP0101, Texas Instruments DS90UB953) to convert MIPI CSI-2 to parallel LVDS or 8-/16-bit CMOS format compatible with its General Configurable Interface. The GPIF supports parallel sensor interfaces up to 100 MHz but lacks MIPI PHY layers.

Is the 512 KB on-chip SRAM accessible for both code execution and DMA buffer storage simultaneously?

Yes, the 512 KB embedded SRAM is unified memory accessible by the ARM926EJ-S CPU for instruction/data and by the distributed DMA controller for packet buffering. Memory mapping is configurable via the SX3 Configuration Utility, allowing allocation splits such as 384 KB for firmware + 128 KB for double-buffered UVC video frames-enabling zero-copy streaming without external RAM.
