CYUSB3017-BZXIT

Application Specific Microcontrollers Overview

The CYUSB3017-BZXIT is a configurable SuperSpeed USB peripheral controller from the EZ-USB SX3 family, manufactured by Infineon Technologies. It integrates a 32-bit ARM926EJ-S CPU operating at 200 MHz with 512 KB of embedded SRAM. The device supports USB 3.2 Gen 1 and USB 2.0 protocols, featuring a 5-Gbps SuperSpeed PHY. It includes a general configurable interface supporting up to 100 MHz operation with 8-, 16-, 24-, or 32-bit data buses. The component operates within a core voltage range of 1.15 V to 1.25 V and I/O voltages from 1.8 V to 3.3 V, housed in a 121-ball BGA package.

Application Specific Microcontrollers Feature Summary

• Integrates an ARM926EJ-S processor running at 200 MHz with 512 KB on-chip SRAM for firmware execution.
• Supports USB 3.2 Gen 1 (5 Gbps) and USB 2.0 compliance with UVC and UAC protocol support.
• Features a general configurable interface capable of Slave FIFO and parallel camera modes up to 100 MHz.
• Includes independent power domains allowing core operation at 1.2 V and flexible I/O voltages.

Application Specific Microcontrollers Applications

• USB Webcams and document cameras
• HDMI and SDI USB video capture cards
• Industrial and medical imaging devices
• USB logic analyzers and oscilloscopes

Application Specific Microcontrollers Procurement Notes

Verify that the ordering suffix 'BZXIT' corresponds to the specific package variant and tape-and-reel packaging configuration required for the design. Confirm RoHS compliance status through official documentation before procurement. Ensure the selected variant matches the intended application profile, as the CYUSB3017 specifically supports UVC/UAC classes unlike other SX3 variants.

Application Specific Microcontrollers Selection Notes

Select the CYUSB3017 when USB Video Class (UVC) and Audio Class (UAC) support are required, distinguishing it from the CYUSB3015/3016 which focus on vendor class applications. Ensure the host system can accommodate the 121-ball BGA footprint and provides the necessary clock frequencies (19.2, 26, 38.4, or 52 MHz). Verify that the external SPI flash memory is compatible with the supported Cypress part numbers for boot operations.

Application Specific Microcontrollers Part Context

The CYUSB3017 belongs to the EZ-USB SX3 family of configurable SuperSpeed controllers. It shares the same silicon die and core architecture with the CYUSB3015 and CYUSB3016 but is differentiated by its pre-configured support for USB Video Class (UVC) and USB Audio Class (UAC) descriptors. This makes it distinct from the data-focused variants in the same series.

Application Specific Microcontrollers Replacement Considerations

The CYUSB3015-BZXIT and CYUSB3016-BZXIT are pin-compatible alternatives within the SX3 family. However, they lack native UVC/UAC support and are configured for USB vendor class applications. Substitution requires reconfiguration via the EZ-USB SX3 Configuration Utility and potential firmware adjustments.
