18 Mbit QDR II SRAM at 250 MHz — what this buys you
The Cypress CY7C1314KV18-250BZCT is a 18 Mbit synchronous SRAM organised as 512K words by 36 bits, using the QDR II architecture that delivers a read and a write on every clock edge. The 250 MHz clock rate yields a peak data bandwidth of 18 Gbit/s on the 36-bit bus — the kind of throughput a network processor or switch fabric line card needs for packet buffer lookups and statistics counters.
Last Buy — plan your final order quantities now
If your BOM still specifies the CY7C1314KV18-250BZCT, you need to secure your lifetime buy quantities before the order window closes. After that, supply moves to the surplus and broker channel. No official replacement part is listed on the record; a pin-compatible QDR II SRAM from the same density and speed grade would be the logical cross-search, but no specific order code is documented as a direct substitute.
165-ball FBGA — layout notes for the 13x15 mm footprint
The 165-ball FBGA (13x15 mm body) uses a 1.0 mm ball pitch. The 36-bit data bus plus address and control signals need four or six inner signal layers for clean fanout on a standard PCB build.
