The 450 MHz clock rate yields a random-access throughput of 900 million transactions per second on the data bus. Organised as 4M x 18, this part targets wide-word memory channels in networking equipment (packet buffers, look-up tables) and compute accelerators where the 18-bit width matches the internal datapath without wasting pins on narrower x8 or x9 parts. ## Supply rail and temperature envelope The core operates from 1.7 V to 1.9 V — the 1.8 V nominal supply aligns with the QDR II+ standard. The 0.2 V tolerance window demands a regulated rail; a direct connection to a 1.8 V switching regulator with ±2% setpoint keeps the SRAM inside its operating range under load transients. This limits deployment to controlled indoor environments — no extended temperature range for telecom outdoor cabinets or industrial floors without active cooling. The 165-FBGA (13x15 mm) package uses a 0.8 mm ball pitch; a 6-layer PCB with via-in-pad or microvia fan-out is typical for signal integrity at 450 MHz.","metaTitle":"Infineon CY7C15632KV18-450BZXC 72Mbit QDR II+ SRAM, 450 MHz","metaDescription":"Infineon CY7C15632KV18-450BZXC 72Mbit synchronous QDR II+ SRAM, 450 MHz clock, 4M x 18 organization, 1.8V supply, 165-FBGA.
