The Cypress CYUSB3065-BZXI is an ARM9-based USB 3.0 peripheral controller from the EZ-USB CX3 family, designed for high-bandwidth video and imaging applications that need a dedicated USB3 pipe without burdening a host processor. Its 512K x 8 internal RAM provides enough buffer space for uncompressed 1080p video frames or multiple bulk endpoints, reducing the need for external SRAM or SDRAM in many designs. The GPIF II interface can be programmed to connect directly to image sensors, CMOS cameras, or parallel-bus ADCs, while the I²S port handles audio codecs in the same datapath.
The 121-ball LFBGA (10x10 mm) requires a controlled reflow profile and x-ray inspection after assembly — plan for a 0.4 mm pitch BGA footprint and a via-in-pad layout for the 1.15V to 1.25V core supply.
ROHS3 compliant per, with no lead or restricted-substance exemptions to track.
