The parallel interface expects the controller to match the QDR-style read/write timing — the 4M x 18 organization provides 18-bit-wide data words, so the controller must handle the 72 Mbit density across the full address range. ## 165-FBGA footprint and supply rails Decoupling should follow the QDR-II+ layout guidelines: one 0.1 µF per supply ball pair, placed within 2 mm of the ball, plus bulk capacitance on the board side. ## Temperature grade and environment This covers most outdoor telecom, base-station, and industrial controller environments. The volatile nature of SRAM means data is lost at power-down — no non-volatile retention.","metaTitle":"Infineon CY7C1568KV18-550BZXI 72Mbit SRAM, 550 MHz, Last Buy","metaDescription":"Infineon CY7C1568KV18-550BZXI 72Mbit DDR II+ SRAM, 550 MHz, -40 to 85°C, 165-FBGA.
