With a 4M x 18 organization, the part delivers 18-bit-wide data at that rate — suited for high-bandwidth lookup tables, packet buffers, or cache in networking and test equipment where latency matters more than density. The parallel memory interface requires careful PCB routing — the 165-ball FBGA footprint with 0.80 mm ball pitch demands controlled impedance traces and matched-length routing for the address/control bus. ## Sourcing an obsolete SRAM — what to expect Because the CY7C25682KV18-400BZC is obsolete, new stock is sourced through independent distribution and surplus channels.","metaTitle":"CY7C25682KV18-400BZC 72Mbit SRAM, 400 MHz, Obsolete","metaDescription":"Infineon CY7C25682KV18-400BZC 72Mbit DDR II+ SRAM, 400 MHz clock, 1.7-1.9V, 165-FBGA.
