Infineon Technologies CYUSB3065-BZXC

Overview

CYUSB3065-BZXC from Infineon is a MIPI CSI-2 to SuperSpeed USB 3.0 bridge controller featuring ARM926EJ-S CPU (200 MHz), 512-KB on-chip SRAM, 4-lane MIPI CSI-2 RX (1 Gbps/lane), USB 3.0 PHY compliant with PIPE 3.0, and 32 physical endpoints. It enables high-bandwidth video streaming from image sensors to USB hosts in embedded vision systems.

For engineers reviewing the CYUSB3065-BZXC datasheet, CYUSB3065-BZXC pinout, CYUSB3065-BZXC application, or CYUSB3065-BZXC equivalent, key selection criteria include MIPI lane count and speed support, USB 3.0 renumerability, integrated ARM9 firmware execution capability, and compatibility with UVC-compliant host stacks for plug-and-play camera deployment.

Technical Context

The CYUSB3065-BZXC implements a dedicated bridge architecture where the ARM926EJ-S core executes real-time firmware to manage MIPI CSI-2 packet parsing, USB 3.0 descriptor handling, and endpoint buffering-without requiring external memory. Its MIPI D-PHY receiver supports LP/HS mode transitions per CSI-2 v1.01 spec, with configurable data lane polarity and timing calibration.

USB interface operation includes full-speed and high-speed fallback, VBUS overvoltage protection, and dynamic reenumeration triggered by sensor hot-plug or format change events. Clocking relies on a 32-kHz watchdog input and a programmable PLL for USB 3.0 reference clock generation at 100 MHz.

FAQ

Does CYUSB3065-BZXC require external RAM for UVC operation?

No. The device integrates 512 KB of on-chip SRAM, sufficient to store UVC descriptors, firmware code, and video DMA buffers for up to 4K30 RAW12 streaming. External memory is optional only for extended feature sets like JPEG compression or multi-sensor aggregation.

Can CYUSB3065-BZXC support MIPI CSI-2 sensors with non-standard lane counts?

Yes. It supports 1–4 active MIPI data lanes dynamically configured via firmware. Unused lanes are electrically terminated internally; lane polarity and timing parameters are adjustable per sensor requirements using the CX3 MIPI Configuration Tool.

What USB host operating systems support CYUSB3065-BZXC out-of-the-box?

Windows 10/11, Linux (UVC 1.1 kernel drivers), and macOS (10.13+) provide native UVC class support. No vendor-specific drivers are needed-only standard UVC descriptors generated by CX3 firmware must match host expectations for resolution, format, and frame rate.

Is the 32-kHz clock input mandatory for CYUSB3065-BZXC operation?

Yes. The 32-kHz crystal or oscillator input (CLKIN_32) is required for the internal watchdog timer and USB suspend/resume timing. Omission prevents proper low-power state transitions and may cause enumeration failure after host sleep/wake cycles.
