Product details

Overview

CYUSB3065-BZXI from Infineon is a MIPI CSI-2 to SuperSpeed USB 3.0 bridge controller featuring an ARM926EJ-S core (200 MHz), 512-KB embedded SRAM, 4-lane MIPI CSI-2 RX (1 Gbps/lane), and full USB 3.0/2.0 compliance. It enables high-bandwidth video streaming from image sensors to USB hosts in digital cameras, webcams, and industrial vision systems.

For engineers reviewing the CYUSB3065-BZXI datasheet, CYUSB3065-BZXI pinout, CYUSB3065-BZXI application, or CYUSB3065-BZXI equivalent, key selection criteria include MIPI lane count, USB 3.0 PHY compliance (PIPE 3.0), supported video formats (RAW12/YUV422/RGB888), SRAM size, and BGA package thermal performance.

Technical Context

The device implements a dedicated MIPI CSI-2 receiver with configurable D-PHY timing, supporting up to four data lanes and a reference clock input (REFCLK) for synchronization. Its USB 3.0 PHY complies with PIPE 3.0 and delivers 5-Gbps aggregate bandwidth with 32 physical endpoints.

The integrated ARM926EJ-S CPU executes firmware directly from on-chip 512-KB SRAM and manages real-time sensor configuration via CCI (I²C-compatible) and video pipeline control. Power domains are split: core at 1.2 V, I/Os at 1.8–3.3 V, enabling flexible interface voltage matching with sensors and peripherals.

Equivalent & Alternatives

The following parts are listed as comparable options for similar MIPI-to-USB bridge applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CYUSB3064-BZXI	2-lane MIPI CSI-2 RX; 256-KB SRAM; identical USB 3.0 PHY and CPU	Targeted at lower-resolution sensors (≤5MP) and cost-sensitive webcams	Select when sensor bandwidth ≤2 Gbps and SRAM footprint <512 KB suffices
USB3380-EZK	No MIPI interface; USB 3.0 hub + PHY only; requires external FPGA or MCU for sensor bridging	Used in legacy designs where MIPI interface is implemented externally	Choose only if existing design already includes FPGA-based MIPI processing and only USB PHY extension is needed

Compared with CYUSB3064-BZXI, CYUSB3065-BZXI provides double MIPI bandwidth and double SRAM-essential for 4K/30fps or multi-sensor fusion. Versus USB3380-EZK, it integrates full sensor-to-USB functionality, eliminating FPGA dependency and reducing total BOM cost by ~35%.

FAQ

Does CYUSB3065-BZXI require external memory to operate as a UVC device?

No. The device contains 512-KB on-chip SRAM sufficient to store boot firmware, video line buffers, and UVC descriptors. External memory is optional only for extended frame buffering or advanced ISP algorithms beyond baseline UVC functionality.

What MIPI CSI-2 sensor configurations are supported out-of-the-box?

The FX3 SDK includes pre-validated firmware for OmniVision OV5640 (2MP) and Aptina AS0260 (1.3MP) sensors. Configuration for other sensors requires use of the CX3 MIPI Configuration Tool plugin to generate timing-accurate D-PHY parameters and register initialization sequences.

Can CYUSB3065-BZXI support simultaneous video and audio streaming?

Yes. It supports concurrent UVC (video) and UAC (audio) class operation via its I²S master interface (up to 192 kHz sampling) and UART/I²C for microphone or codec control-enabling composite USB devices like video IP phones and telemedicine units.

Is the 10 × 10 mm BGA package compatible with standard reflow profiles?

Yes. The Pb-free 121-ball BGA uses JEDEC J-STD-020-compliant moisture sensitivity level (MSL) 3 packaging and is qualified for standard lead-free reflow profiles (peak 260°C). Board layout must observe 0.8-mm ball pitch spacing and thermal pad grounding per Infineon's hardware design guidelines.
