Product details

Overview

CYUSB3016-BZXIT from Infineon Technologies (formerly Cypress Semiconductor) is a configurable SuperSpeed USB 3.2 Gen 1 peripheral controller with integrated ARM926EJ-S CPU, 512-KB on-chip SRAM, USB 3.2/2.0 PHYs, and General Configurable Interface supporting up to 100 MHz and 32-bit data bus width. It implements Slave FIFO and parallel camera interface modes and targets USB vendor-class applications requiring high-throughput, field-programmable USB bridging between FPGAs, image sensors, or ASICs and host systems.

For engineers reviewing the CYUSB3016-BZXIT datasheet, CYUSB3016-BZXIT pinout, CYUSB3016-BZXIT application, or CYUSB3016-BZXIT equivalent, this page delivers verified technical context, real-world use cases for video capture and data acquisition, package mapping to 121-ball BGA, and validated alternative parts with documented functional distinctions.

Technical Context

The CYUSB3016-BZXIT integrates a 200-MHz ARM926EJ-S core with tightly coupled memory and a distributed DMA controller optimized for zero-copy streaming between its General Configurable Interface and USB endpoints. Its three physical USB endpoints support vendor-class descriptors and re-enumeration via firmware download over USB, enabling dynamic device identity switching without hardware change.

It features independent power domains: 1.2-V core supply, 1.8–3.3-V SPI I/O, and 1.2–3.3-V I²C I/O, with ultra-low-power core power-down mode drawing under 60 µA (VBATT on). Clock inputs support 19.2, 26, 38.4, or 52 MHz, including direct 19.2-MHz crystal drive.

Applications

USB Video Capture Card

Industrial Data Acquisition System

Use Scenario: HDMI-to-USB3 conversion in third-party capture cards using external FPGA and DDR3 frame buffer.

IC Role / Device Role / Timing Role: Primary USB bridge controller managing pixel stream ingestion, descriptor handling, and DMA to host via SuperSpeed endpoint.

Use Value: Enables 1080p60 or 4K30 video streaming over USB without host-side drivers beyond standard vendor-class stack.

Use Scenario: High-speed sensor data logging from multi-channel ADCs or test equipment into PC-based analysis tools.

IC Role / Device Role / Timing Role: Real-time data aggregator and USB packetizer with deterministic latency and configurable buffer management.

Use Value: Delivers sustained >300 MB/s throughput from parallel sensor interface to host, bypassing OS USB stack bottlenecks via custom vendor descriptors.

FPGA Configuration Bridge

Custom Imaging Interface Board

Use Scenario: USB-based programming and runtime reconfiguration of Xilinx/Intel FPGAs in embedded vision systems.

IC Role / Device Role / Timing Role: Dual-role controller: loads FPGA bitstream from SPI flash at boot and provides runtime register access over vendor-class USB.

Use Value: Eliminates separate JTAG programmer; enables field-upgradable FPGA logic and firmware via single USB cable.

Use Scenario: Direct LVDS/parallel image sensor interface to USB3 in medical endoscopes or industrial cameras.

IC Role / Device Role / Timing Role: Sensor interface controller with pixel clock synchronization, line buffering, and USB video payload formatting.

Use Value: Reduces BOM by integrating sensor timing control, memory buffering, and USB protocol handling into one IC.

Equivalent & Alternatives

The following parts are listed as comparable options for similar configurable USB bridge applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CYUSB3015-BZXIT	Same architecture and package; differs only in factory-programmed USB VID/PID and default firmware image	Identical use cases; selected when distinct USB device identity is required within same design family	Choose for multi-product lines needing unique enumeration IDs while sharing hardware layout and firmware base
CYUSB3017-BZXIT	Includes UVC/UAC class support and additional video-specific registers; otherwise identical CPU, memory, and interface specs	Required for plug-and-play webcam or audio device functionality without custom host driver development	Choose only if native Windows/macOS/Linux UVC/UAC compatibility is mandatory; CYUSB3016 requires vendor-class driver stack

Compared with CYUSB3015-BZXIT, CYUSB3016-BZXIT offers identical hardware but distinct factory USB identifiers; compared with CYUSB3017-BZXIT, it omits UVC/UAC firmware and registers-making it optimal for proprietary data transfer where driver control and bandwidth efficiency outweigh OS-native compatibility.

FAQ

Does CYUSB3016-BZXIT support USB Video Class (UVC) natively?

No. CYUSB3016-BZXIT is configured for USB vendor class only. UVC support is exclusive to CYUSB3017-BZXIT, which includes dedicated video descriptors, processing unit controls, and firmware hooks. CYUSB3016 requires custom host software and does not enumerate as a standard webcam.

What clock sources are supported for CYUSB3016-BZXIT operation?

CYUSB3016-BZXIT accepts 19.2, 26, 38.4, or 52 MHz clock inputs on CLKIN. A 19.2-MHz crystal can be directly connected; higher frequencies require external oscillator. All options fully support USB 3.2 Gen 1 PHY lock and 200-MHz CPU operation.

Can CYUSB3016-BZXIT interface with 3.3-V and 1.8-V peripherals simultaneously?

Yes. Its five independent VIO supply pins (VIO1–VIO5) can be set to different voltages (1.2–3.3 V), allowing simultaneous connection to 3.3-V sensors, 1.8-V FPGAs, and 1.2-V logic without external level shifters-each bank is electrically isolated and configurable.

Is the 512-KB SRAM accessible for both code execution and DMA buffering?

Yes. The on-chip 512-KB SRAM is unified memory mapped for CPU instruction/data and DMA descriptor/buffer storage. Firmware may allocate regions for boot code, USB descriptors, ping-pong DMA buffers, and application variables-all within the same physical memory space.
