The 278 MHz clock rate supports high-bandwidth burst transfers for network packet buffers, telecom line cards, and test equipment where deterministic read-write turnaround matters. Parallel interface keeps pin count manageable on the 165-FBGA (13x15 mm) footprint. Supply range 1.7V–1.9V aligns with low-voltage core logic; commercial temperature grade 0°C to 70°C limits it to indoor, temperature-controlled environments. This part is marked obsolete by Infineon. No last-time-buy window remains open. Procurement must source through independent surplus or broker channels. For a long-term BOM, evaluate a pin-compatible alternative in the same DDR II family; the CY7C1318 series shares footprint and interface across density options, but verify the specific speed grade and temperature range against your design.","metaTitle":"Infineon CY7C1318CV18-278BZXC DDR II SRAM, 18 Mbit, 278 MHz","metaDescription":"Infineon CY7C1318CV18-278BZXC DDR II synchronous SRAM, 18 Mbit organized 1M x 18, 278 MHz clock, parallel interface, 1.7V–1.9V supply, 0°C–70°C, 165-FBGA.
