Infineon Technologies CYUSB2014-BZXC

Overview

CYUSB2014-BZXC from Infineon is a USB 3.2 Gen 1/USB 2.0 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 Gen 1 PHY (5 Gbps), HS-OTG host/peripheral capability, and multiple serial interfaces (SPI up to 33 MHz, UART up to 4 Mbps, I²C at 1 MHz, I²S transmitter). Used in high-bandwidth video capture cards and industrial cameras for real-time sensor-to-PC data streaming.

For engineers reviewing the CYUSB2014-BZXC datasheet, CYUSB2014-BZXC pinout, CYUSB2014-BZXC application, or CYUSB2014-BZXC equivalent, key selection criteria include GPIF II bus width configurability, USB 3.2 Gen 1 compliance (TID #340800007), ARM926EJ-S firmware extensibility, low-power core-down mode (<60 µA), and BGA-121 package compatibility with FPGA/video sensor interconnects.

Technical Context

The CYUSB2014-BZXC implements a dual-mode USB controller with independent USB 3.2 Gen 1 (5 Gbps) and USB 2.0 (480 Mbps) PHY layers, enabling simultaneous SuperSpeed and High-Speed enumeration. Its ARM926EJ-S CPU executes firmware directly from on-chip SRAM and supports RTOS-based development via ThreadX v5 in the EZ-USB SDK.

GPIF II operates as a synchronous state-machine-driven parallel interface with configurable clocking (up to 100 MHz), 16 programmable control signals, and support for Slave FIFO, SRAM, and custom timing protocols-enabling direct connection to image sensors, FPGAs, and ADCs without external glue logic.

FAQ

What boot options does CYUSB2014-BZXC support?

CYUSB2014-BZXC supports four boot modes: USB, SPI Flash, I²C EEPROM, and Parallel NOR Flash. Boot source is selected via GPIO strap pins at reset. USB boot enables firmware download directly from host PC during development; SPI Flash is most common in production for fast, reliable startup with minimal external components.

Does CYUSB2014-BZXC require an external crystal?

Yes - it requires a 19.2 MHz fundamental-mode crystal connected to XIN/XOUT pins for USB 3.2 Gen 1 PHY clock generation and system timing. The crystal must meet ±50 ppm frequency tolerance and load capacitance matching per Infineon's hardware design guidelines (AN70707).

Can CYUSB2014-BZXC operate as a USB host?

Yes - it supports USB On-The-Go (OTG) Supplement v2.0 in HS-OTG mode, allowing dynamic role switching between host and peripheral. Host capability is limited to single downstream port and requires external VBUS control circuitry and ID pin detection per USB OTG specifications.

Is GPIF II configuration done in hardware or firmware?

GPIF II configuration is defined in firmware using Cypress's GPIF II Designer tool, which generates C header files and initialization code. The resulting state machine is loaded into on-chip RAM at runtime; no hardware reconfiguration or external PROM is required - enabling field-upgradable interface timing and protocol behavior.
