It integrates an ARM9 core with 512K x 8 of embedded RAM and a flexible GPIF interface, along with I2C, I2S, SPI, UART, and USB connectivity. This combination makes it the bridge chip for designs that need to move bulk data between a host USB 3.0 port and a parallel or serial peripheral — think high-speed imaging, software-defined radio, or FPGA configuration over USB. The 121-TFBGA package (10x10 mm) and commercial temperature range (0°C to 70°C) target controlled indoor environments like lab instrumentation, test equipment, and consumer electronics. ## Key ratings and what they mean for the BOM The ARM9 core runs the FX3 firmware stack and handles USB protocol processing without an external host CPU. The 512K x 8 RAM is the data buffer for SuperSpeed transfers. ## Sourcing and lifecycle reality The CYUSB3014-BZXCT carries an Active lifecycle status with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect, so it remains qualified for new designs and production builds.","metaTitle":"CYUSB3014-BZXCT EZ-USB FX3 USB Controller, ARM9, 512K RAM","metaDescription":"CYUSB3014-BZXCT from Infineon (Cypress) EZ-USB FX3 series.
