That combination typically means a PCN has been issued or is imminent. No official last-time-buy date or successor MPN appears in the record. If this part is on a production BOM, request the current PCN status and consider qualifying a replacement before the window closes. available via RFQ confirmation now is genuine factory-date-code material; mystery lots surfacing later may be suspect. ## Sourcing and fit for your BOM The 36Mbit density and 18-bit data width target designs that need moderate-depth, wide-word buffer memory — common in Ethernet frame buffers, CAM lookaside, and DSP coefficient storage.","metaTitle":"Infineon CY7C1243KV18-450BZC QDR II+ SRAM, 36Mbit 450 MHz","metaDescription":"CY7C1243KV18-450BZC 36Mbit QDR II+ synchronous SRAM, 450 MHz clock, 2M x 18 organization, 1.7-1.9V supply, 165-FBGA.
