Infineon Technologies CYUSB2014-BZXCT

Overview

CYUSB2014-BZXCT 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 data buses. It integrates USB 3.2 Gen 1 (5-Gbps) PHY, HS-OTG host/peripheral capability, and dual-power-domain I/O (1.2 V core, 1.8–3.3 V I/O). Used in high-bandwidth video capture cards and industrial cameras for real-time sensor-to-PC streaming.

For engineers reviewing the CYUSB2014-BZXCT datasheet, CYUSB2014-BZXCT pinout, CYUSB2014-BZXCT application, or CYUSB2014-BZXCT equivalent, key selection criteria include GPIF II timing compliance at 100 MHz, USB 3.2 Gen 1 enumeration stability, slave FIFO interface latency, and 121-ball BGA thermal/mechanical layout constraints in compact embedded vision systems.

Technical Context

The CYUSB2014-BZXCT implements a dedicated USB 3.2 Gen 1 link layer with integrated 5-Gbps SerDes PHY and full backward compatibility to USB 2.0 High-Speed (480 Mbps). Its ARM926EJ-S CPU executes firmware directly from on-chip SRAM and supports RTOS-based applications via ThreadX v5 integration in the EZ-USB SDK.

GPIF II operates as a fully configurable state-machine-driven parallel interface with up to 16 control signals and synchronous/asynchronous timing modes-enabling direct connection to FPGA logic, image sensors, or memory-mapped peripherals without external glue logic.

FAQ

What boot options does CYUSB2014-BZXCT support?

CYUSB2014-BZXCT supports multiple boot sources: internal ROM bootloader (default), SPI flash (with configurable address mapping), I²C EEPROM, and USB-host download via vendor command. Boot mode is selected by GPIO strap pins at power-up, enabling field firmware updates without JTAG access.

Does CYUSB2014-BZXCT require an external crystal?

Yes-it requires a 19.2 MHz crystal (or oscillator) for USB 3.2 Gen 1 clock recovery and USB 2.0 PLL stability. The crystal connects to XIN/XOUT pins; internal oscillator is insufficient for USB certification. Layout must follow Infineon's 19.2-MHz crystal matching network guidelines to pass USB-IF electrical tests.

Can CYUSB2014-BZXCT operate as a USB host?

No-it functions exclusively as a USB device or OTG peripheral. While it supports HS-OTG Supplement v2.0, it lacks USB host controller hardware (e.g., root hub, host PHY, scheduler). It cannot enumerate or control other USB peripherals; its OTG role is limited to device-mode operation with optional ID-pin detection for cable orientation.

Is GPIF II timing guaranteed across voltage and temperature?

Yes-Infineon specifies GPIF II AC timing (setup/hold, clock-to-output) across full commercial temperature (0°C to +70°C) and supply (1.14–1.26 V core, 1.71–3.46 V I/O) ranges per datasheet Section 19.3. Timing margins are validated with worst-case corner silicon and include ±100 ps process variation; no derating needed for production designs.
