QDR II (Quad Data Rate) architecture delivers two read and two write data words per clock cycle, giving an effective data rate of 666 MHz per I/O pin. For a 18-bit-wide bus, that translates to roughly 12 Gbps of aggregate bandwidth — the kind of throughput a network line card or high-end test instrument needs for packet buffer or acquisition memory. The 1.8 V core supply demands tight decoupling: a 100 nF per power ball plus a bulk 10 µF within 5 mm of the package is the usual starting point. Cypress lists the CY7C1513KV18-333BZI as Obsolete. For a BOM line that still calls out this exact density and speed grade, the sourcing path runs through independent distribution — last-time-buy inventory or verified surplus. The 333 MHz speed bin is the most common in the KV18 family, so stock does surface periodically, but it is not a part you can blanket-order from franchised channels. ## Memory organization and bus width Organized as 4M words × 18 bits. The 18-bit width is typical for designs that carry parity or ECC alongside 16-bit data — common in telecom frame processors and test equipment. The 4M depth gives 4 M entries per address, enough for moderate-depth packet buffers or trace capture. If the application needs deeper memory, the QDR II family scales to 144 Mbit in the same footprint; if narrower width suffices, the ×9 variants save pins.","metaTitle":"Cypress CY7C1513KV18-333BZI QDR II SRAM, 72 Mbit, 333 MHz","metaDescription":"Cypress CY7C1513KV18-333BZI 72 Mbit Synchronous QDR II SRAM, 4M x 18, 333 MHz clock, 1.7-1.9V, -40°C to 85°C, 165-LBGA.

Both are 72 Mbit QDR II SRAM in the same 165-FBGA package and 1.8 V supply. The 400 MHz part offers roughly 20% more bandwidth but draws higher active current.
