Infineon Technologies CYUSB3014-BZXCT

Overview

CYUSB3014-BZXCT from Infineon is a USB 3.2 Gen 1 (5 Gbps) and USB 2.0 programmable controller with ARM926EJ-S core (200 MHz), 512 KB SRAM, 32 physical endpoints, and GPIF II interface supporting 8-/16-/24-/32-bit buses up to 100 MHz - used in high-bandwidth video capture cards and industrial camera systems.

For engineers reviewing the CYUSB3014-BZXCT datasheet, CYUSB3014-BZXCT pinout, CYUSB3014-BZXCT application, or CYUSB3014-BZXCT equivalent, this page delivers verified technical context, package mapping, real-world use value per application, and validated alternative options for embedded USB SuperSpeed system integration.

Technical Context

The CYUSB3014-BZXCT integrates a dual-mode USB 3.2 Gen 1 + USB 2.0 PHY with full OTG support, enabling simultaneous host/peripheral operation. Its GPIF II engine operates at 100 MHz with configurable timing and up to 16 control signals, allowing direct interfacing to FPGAs, image sensors, and memory-mapped peripherals without external glue logic.

The ARM926EJ-S CPU runs firmware at 200 MHz with deterministic interrupt latency, while independent power domains isolate 1.2-V core logic from 1.8–3.3-V I/Os (UART, SPI, I2S) and 1.2–3.3-V I2C, enabling mixed-voltage system design and ultra-low-power sleep modes (<60 µA with VBATT).

Key Specifications

FAQ

What boot options does CYUSB3014-BZXCT support?

CYUSB3014-BZXCT supports four boot modes: USB, SPI Flash, I²C EEPROM, and GPIO-controlled selection. Firmware can be loaded from external SPI flash (up to 16 MB) or streamed over USB during enumeration. Boot configuration is set via GPIO pins at power-up and requires no external microcontroller.

Does CYUSB3014-BZXCT 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. The internal PLL multiplies this to 400 MHz for the USB PHY and derives other clocks (e.g., 100 MHz for GPIF II). No external oscillator is needed if crystal meets load capacitance and ESR specs per datasheet Table 23.

Can CYUSB3014-BZXCT operate as a USB host?

Yes - it supports USB On-The-Go (OTG) Supplement v2.0, enabling dual-role operation. As a host, it can enumerate and control USB mass storage, HID, or CDC devices. Host functionality requires external VBUS switching and overvoltage protection circuitry per Section 3.3 of the datasheet.

Is GPIF II configuration done in hardware or firmware?

GPIF II configuration is firmware-defined: users generate timing/state-machine descriptors using Cypress's GPIF II Designer tool, compile them into binary tables, and load them into the device's RAM at runtime. No hardware reconfiguration is required - all interface behavior is dynamically modifiable via firmware update.
