Infineon Technologies CYUSB2014-BZXIT

Overview

CYUSB2014-BZXIT from Infineon is a USB 3.2 Gen 1 and USB 2.0 compliant SuperSpeed USB controller IC 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 PHY (5 Gbps), HS-OTG host/peripheral capability, and multiple serial interfaces including SPI (33 MHz), UART (4 Mbps), I²C (1 MHz), and I²S (up to 192 kHz). Used in high-bandwidth video capture systems requiring real-time data streaming over USB.

For engineers reviewing the CYUSB2014-BZXIT datasheet, CYUSB2014-BZXIT pinout, CYUSB2014-BZXIT application, or CYUSB2014-BZXIT equivalent, key selection criteria include USB 3.2 Gen 1 PHY compliance, GPIF II configurability for FPGA/ASIC interfacing, ARM9-based firmware extensibility, low-power core operation (≤60 µA in power-down), and BGA-121 package compatibility with high-density PCB layouts.

Technical Context

The CYUSB2014-BZXIT implements a dual-mode USB controller with independent USB 3.2 Gen 1 (5 Gbps) and USB 2.0 (480 Mbps) physical layers, enabling backward-compatible enumeration and renumerations. Its ARM926EJ-S CPU executes firmware directly from on-chip SRAM and supports RTOS integration via ThreadX v5.

GPIF II operates as a fully synchronous, state-machine-driven parallel interface with up to 16 configurable control signals and programmable timing-enabling direct connection to image sensors, FPGAs, or memory-mapped peripherals without external glue logic. Clocking supports 19.2/26/38.4/52 MHz crystal or oscillator inputs, with internal PLLs generating required USB and system clocks.

FAQ

What clock sources does CYUSB2014-BZXIT support?

The device accepts 19.2 MHz, 26 MHz, 38.4 MHz, or 52 MHz crystal or oscillator inputs. A 19.2 MHz crystal is explicitly supported for USB 3.2 reference clock generation. Internal PLLs derive all required system clocks-including 100 MHz for GPIF II and 200 MHz for the ARM9 core-from the selected input.

Does CYUSB2014-BZXIT require external memory for operation?

No. It contains 256 KB of on-chip SRAM sufficient for boot code, USB descriptors, GPIF II state machines, and application buffers. External memory is optional and only needed for large firmware images or extended data buffering beyond SRAM capacity.

Can CYUSB2014-BZXIT operate as a USB host?

Yes. It supports High-Speed On-The-Go (HS-OTG) per USB OTG Supplement v2.0, enabling dynamic role switching between USB device and host modes under firmware control-critical for portable scanners, printers, and medical devices that must connect to peripherals.

Is the GPIF II interface compatible with Xilinx or Intel FPGAs?

Yes. The GPIF II supports 8-/16-/24-/32-bit synchronous and asynchronous protocols with user-configurable timing. Cypress provides verified reference designs and adapter boards (e.g., CYUSB3KIT-001) for Xilinx Artix-7 and Intel Cyclone V FPGAs, including timing closure guidance and IBIS models.
