The 2M x 36 organization feeds wide datapaths — think network switch look-up tables, test equipment pattern buffers, or baseband processing where the bus width matches the word size. The 165-FBGA (13x15 mm) footprint is a standard high-density SRAM land pattern. Infineon lists this part as Obsolete. The last-time-buy window has closed, so new inventory comes from independent surplus and broker channels — lot-specific, traceable to the original manufacturer, and confirmed at RFQ. ## 450 MHz clock rate and the read-write pipeline The 450 MHz clock on a DDR II+ interface means data is transferred on both edges — effective data rate is 900 MT/s per pin. For a 36-bit-wide bus, that is 32.4 Gbit/s raw bandwidth into the SRAM array. The limiting factor in a real system is the controller's ability to sustain back-to-back read-write transitions without dead cycles. The 2M x 36 organization is a natural fit for 36-bit-wide datapaths (e.g., 32-bit data + 4-bit parity or ECC). A 72-bit wide bus would require two devices in parallel, matched on clock skew within the same FBGA footprint. The 165-LBGA (13x15 mm) package is a standard JEDEC footprint for high-density synchronous SRAM. Surface-mount assembly with the listed Tray packaging is standard for volume reflow.","metaTitle":"CY7C1550KV18-450BZXI 72Mbit SRAM, 450 MHz, Obsolete","metaDescription":"Infineon CY7C1550KV18-450BZXI 72Mbit DDR II+ SRAM, 450 MHz, -40 to 85°C.
