The 250 MHz clock rate means the memory delivers back-to-back transactions at full speed, ideal for networking packet buffers, test equipment waveform capture, and any design where the FPGA or ASIC needs a high-bandwidth scratchpad without DRAM refresh overhead. ## 1.8V supply, industrial temperature: where it fits The part runs on a 1.7V to 1.9V supply, squarely in the 1.8V logic family. That means the board needs a clean 1.8V rail — no 3.3V or 2.5V plane will do. If your system lives in a temperature-controlled server room, the industrial rating is still fine; it just gives you margin. The 165-FBGA is the supplier device package; the same die also ships in a 165-LBGA variant. Surface-mount only — no socketed prototyping, so first-article assembly and X-ray inspection are non-negotiable. Cypress lists the CY7C1312KV18-250BZI as Active. The base product number is CY7C1312; the KV18 suffix identifies the 1.8V supply and 250 MHz speed grade.","metaTitle":"Cypress CY7C1312KV18-250BZI QDR II SRAM, 18Mbit, 250 MHz","metaDescription":"Cypress CY7C1312KV18-250BZI synchronous QDR II SRAM, 18 Mbit, 250 MHz clock, 1.8V supply, industrial temp.

The -250BZI suffix uses a 165-FBGA (13x15 mm) while the -250BZXC suffix uses a different 165-ball BGA variant. Both are 18 Mbit QDR II SRAMs at 250 MHz with the same 1.8V supply and industrial temperature range. Pin compatibility depends on the specific ball map — check the Cypress datasheet for the exact footprint difference."},{"question":"Can CY7C1312KV18-250BZI be used in 1.8V systems?","answer":"Yes. The supply voltage range is 1.7V to 1.9V, which covers a nominal 1.8V rail. The part is designed for 1.8V logic families — it won't work on 3.3V or 2.5V supplies."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1312KV18-250BZI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1312KV18-250BZI when reusing this data.
