The parallel interface and 1.7V to 1.9V core supply target high-throughput buffer applications in networking or test equipment where deterministic access latency matters — the DDR II+ double-data-rate bus delivers two data words per clock cycle, effectively halving the pin count for a given bandwidth compared to a single-data-rate part. Infineon has marked this part Obsolete. For sustainment programs that already qualify this footprint, the remaining supply moves through independent distribution — quantities are lot-specific and confirmed at RFQ. A board-spin to a current-generation QDR or DDR SRAM is the long-term migration path, but for existing BOM lines this is the exact order code to source. ## Package and board-fit — 165-ball FBGA The supplier device package is 165-FBGA (13x15); the footprint matches the industry-standard 165-ball FBGA land pattern for this density class. IR drop across the PCB plane should be budgeted into the regulator setpoint.","metaTitle":"CY7C1268KV18-450BZXC Infineon SRAM, 36Mbit, 450 MHz","metaDescription":"CY7C1268KV18-450BZXC is an obsolete 36Mbit DDR II+ SRAM from Infineon. 450 MHz clock, 2M x 18 organization, 165-FBGA.
