Product details

Overview

CYUSB2014-BZXI from Infineon is a USB 3.2 Gen 1 and USB 2.0 peripheral controller featuring an ARM926EJ-S core running at 200 MHz, 256 KB embedded SRAM, and a programmable 100-MHz GPIF II interface supporting 8-/16-/24-/32-bit buses. It integrates USB 3.2 SuperSpeed PHY (5 Gbps), HS-OTG host/peripheral capability, and 32 physical endpoints. Used in high-bandwidth video capture cards and industrial cameras for real-time sensor-to-PC streaming.

For engineers reviewing the CYUSB2014-BZXI datasheet, CYUSB2014-BZXI pinout, CYUSB2014-BZXI application, or CYUSB2014-BZXI equivalent, key selection criteria include GPIF II timing compliance, USB 3.2 Gen 1 enumeration stability, ARM926EJ-S firmware debug access via JTAG, and 1.2-V core / 1.8–3.3-V I/O voltage domain separation.

Technical Context

The CYUSB2014-BZXI implements a dual-mode USB controller with full USB 3.2 Gen 1 (5 Gbps) and backward-compatible USB 2.0 (480 Mbps) transceivers. Its ARM926EJ-S CPU executes firmware directly from on-chip SRAM and supports ThreadX RTOS integration via the EZ-USB FX3 SDK.

GPIF II operates as a synchronous state-machine-driven parallel interface with configurable clocking (up to 100 MHz), programmable bus width, and up to 16 control signals - enabling direct connection to FPGAs, image sensors, and memory-mapped peripherals without external glue logic.

Applications

Digital Video Capture Card

Industrial Camera Interface

Use Scenario: Real-time HDMI/SDI-to-USB3 conversion for PC-based vision analysis.

IC Role / Device Role / Timing Role: USB peripheral controller with GPIF II acting as synchronous slave FIFO to FPGA video pipeline.

Use Value: Eliminates external USB bridge IC; enables sub-100 µs frame latency using hardware handshaking (SLRD/SLWR) and 100-MHz PCLK.

Use Scenario: High-resolution CMOS sensor data acquisition in factory automation systems.

IC Role / Device Role / Timing Role: Host-side USB endpoint managing burst transfers from sensor over parallel GPIF II bus.

Use Value: Sustained 320 MB/s throughput (32-bit @ 100 MHz) meets 4K@60fps raw Bayer streaming requirements.

Medical Imaging Device

Test & Measurement Equipment

Use Scenario: Ultrasound probe data streaming to diagnostic workstation via USB 3.2.

IC Role / Device Role / Timing Role: USB 3.2 Gen 1 peripheral with renumerated UVC + custom class descriptors for proprietary imaging protocols.

Use Value: Dual-class enumeration preserves Windows UVC driver compatibility while enabling vendor-specific control channel via CDC ACM interface.

Use Scenario: High-speed logic analyzer data offload from FPGA acquisition buffer to host PC.

IC Role / Device Role / Timing Role: USB device controller with asynchronous Slave FIFO mode for variable-length trigger-captured samples.

Use Value: Hardware FIFO depth (up to 16 KB) absorbs jitter between FPGA sampling clock and USB packet boundaries.

Equivalent & Alternatives

The following parts are listed as comparable options for similar USB 3.2 peripheral controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CYUSB3014-BZXI	512 KB SRAM, same package and pinout	Higher memory headroom for complex UVC + audio + HID composite devices	Select when firmware exceeds 256 KB or requires dual simultaneous streaming pipelines
CX3-EBZ	MIPI CSI-2 receiver integrated; no GPIF II; fixed 2-lane CSI-2 + USB 3.0	Optimized for direct CMOS image sensor connection only - no general-purpose parallel interface	Select only for MIPI-based camera modules where sensor output is CSI-2, not parallel

Compared with CYUSB3014-BZXI, this part trades SRAM capacity for cost and footprint; compared with CX3-EBZ, it offers full GPIF II flexibility at the expense of dedicated MIPI support - making it optimal for non-MIPI, high-customization USB peripheral designs.

FAQ

What boot sources does CYUSB2014-BZXI support?

CYUSB2014-BZXI supports boot from internal ROM (for recovery), SPI flash (primary production method), I2C EEPROM, and USB host download via vendor command. Boot mode is selected by GPIO strap pins at power-up, and the EZ-USB FX3 SDK provides tools to generate signed firmware images for secure SPI boot.

Does CYUSB2014-BZXI require an external USB PHY?

No. CYUSB2014-BZXI integrates a fully compliant USB 3.2 Gen 1 (5 Gbps) SuperSpeed PHY and USB 2.0 High-Speed PHY. Only passive termination (22-Ω series resistors on USB_DP/DM, 45-Ω AC-coupling caps) and proper PCB layout per Infineon's AN70707 are required - no external PHY chip needed.

Can GPIF II operate synchronously with an external clock source?

Yes. GPIF II can be configured to use an external clock (PCLK_EXT) instead of the internal 100-MHz clock. This allows synchronization to an external video pixel clock or FPGA system clock, ensuring deterministic phase alignment for time-critical sensor data capture without FIFO resynchronization overhead.

Is JTAG debugging supported in all power modes?

JTAG is fully functional in active and sleep modes but disabled in deep power-down (core power-off) mode where VBATT is present. When VBATT is removed, JTAG is inactive until VDD_CORE is restored. Debug access remains available during low-power suspend states where CPU clocks are gated but SRAM retention is maintained.
