The 450 MHz clock rate means the part delivers a 900 MHz effective data rate on the read and write ports running independently — each port toggles at the full clock speed, so the aggregate bandwidth is double what a single-port SRAM at the same frequency would give. That matters when the downstream logic (a network processor, an FPGA packet buffer, a high-speed ASIC) needs to read and write in the same cycle without arbitration stalls. The QDR II+ interface keeps the read and write buses separate, so the controller never waits for a bus turn-around. ## Package and board-fit — 165-ball FBGA footprint Housed in a 165-ball LBGA (13x15 mm body per the supplier device package), the part is a surface-mount BGA with 0.80 mm ball pitch — a standard four-layer PCB can fan it out without micro-vias. The 1.7 V to 1.9 V core supply means the VDDQ rail is separate from the 1.8 V or 2.5 V I/O voltage the QDR II+ bus expects; the board needs a dedicated regulator for the core domain. The tray packaging is the standard BGA delivery format — no reel, so pick-and-place lines that handle trays are the expected assembly flow.","metaTitle":"Infineon CY7C25632KV18-450BZXI QDR II+ SRAM, 72Mbit, 450 MHz","metaDescription":"CY7C25632KV18-450BZXI QDR II+ synchronous SRAM, 72Mbit (4M x 18), 450 MHz clock, 1.7-1.9V, -40 to 85°C, 165-FBGA.
