The 1.7 V to 1.9 V core supply keeps I/O levels consistent with low-voltage logic families, and the 165-FBGA package (13x15 mm) fits a standard surface-mount footprint for high-speed memory arrays. ## 550 MHz clock — what it buys the design At 550 MHz, this part delivers a double-data-rate (QDR) transaction on every clock edge, effectively doubling the throughput per pin versus a single-data-rate SRAM at the same frequency. That matters when the FPGA or ASIC on the other side of the bus is running a 550 MHz memory controller and needs a matched-speed partner without wait states. The 4M x 18 organization maps directly to an 18-bit data bus; if the design calls for 36-bit width, the sibling CY7C2565XV18-633BZC (2M x 36, 633 MHz) is a higher-frequency alternative with a wider word, though at half the depth per chip. ## EOL status — sourcing reality for this line ## Temperature grade and package — deployment boundaries","metaTitle":"Cypress CY7C25632KV18-550BZC QDR II+ SRAM, 72Mbit, 550 MHz","metaDescription":"Cypress CY7C25632KV18-550BZC QDR II+ synchronous SRAM, 72 Mbit (4M×18), 550 MHz clock, 1.7 V–1.9 V supply, 165-FBGA, 0°C–70°C.
