CYUSB3035-BZXI

Application Specific Microcontrollers Overview

The CYUSB3035-BZXI is an EZ-USB FX3S SuperSpeed USB controller featuring a 200-MHz ARM926EJ-S core and 512 KB embedded SRAM. It supports USB 3.0 at 5 Gbps with 32 physical endpoints and includes a configurable 100-MHz GPIF II interface for external device connectivity. The device integrates dual SD/eMMC storage ports with RAID support, HS-OTG capabilities, and serial peripherals including UART, SPI, I2C, and I2S. Operating at 1.2 V core voltage within a -40°C to +85°C range, it utilizes a 10-mm × 10-mm BGA package.

Application Specific Microcontrollers Applications

• Digital video camcorders and digital still cameras
• Industrial cameras and medical imaging devices
• Surveillance cameras and video capture cards
• RAID controllers and USB Disk on Module

Application Specific Microcontrollers Procurement Notes

Verify the specific SRAM configuration (512 KB vs 256 KB) as part numbers in the FX3S series may vary by memory size. Confirm the suffix 'BZXI' corresponds to the required industrial temperature grade (-40°C to +85°C) and Pb-free BGA packaging. Ensure compatibility with the EZ-USB FX3 SDK for firmware development.

Application Specific Microcontrollers Selection Notes

Select this component when a fully integrated USB 3.0 peripheral controller with onboard processing is required. The FX3S variant offers lower power consumption compared to the standard FX3. Verify that the application requires the specific 512 KB SRAM capacity and 16-bit GPIF II width supported by this model.

Application Specific Microcontrollers Part Context

The CYUSB3035-BZXI belongs to the EZ-USB FX3S family, which is the low-power successor to the EZ-USB FX3 series. While sharing the ARM9 architecture and USB 3.0 interface, the FX3S distinguishes itself through optimized power domains and reduced active current consumption, making it suitable for battery-powered or thermally constrained portable applications.

Application Specific Microcontrollers Replacement Considerations

The CYUSB3014-BZXI serves as a functional alternative within the FX3 family but lacks the integrated SD/eMMC storage ports found in the FX3S series. Developers must verify if the absence of the S-Port meets system requirements before substituting.
