ARM9 core with 512 KB RAM for SuperSpeed USB throughput
The CYUSB3014-BZXI is an EZ-USB FX3 controller built around an ARM9 core, purpose-designed as a SuperSpeed USB peripheral controller. It carries 512K x 8 of embedded RAM — enough to buffer a full isochronous endpoint payload without external memory for many video and imaging pipelines.
Interface set and I/O count
The part integrates GPIF, I²C, I²S, SPI, UART, and USB interfaces, with 60 general-purpose I/O lines. The GPIF block is a programmable state machine that can connect directly to image sensors, ADCs, or FPGA parallel buses without an external bridge — the timing is configured in firmware, not in the hardware layout.
The 0.50 mm ball pitch on the 121-FBGA calls for a via-in-pad or microvia breakout on a 4-layer board — the inner layers carry the 1.2 V plane and the ground return for the USB 3.0 differential pairs.
Temperature grade and compliance
ROHS3 compliant per — no exemption conflict for lead-free assembly.
