A 250 MHz DDR II SRAM transfers data at an effective 500 MHz rate on a 36-bit-wide bus, yielding a peak bandwidth of 18 Gbit/s. That throughput is what makes this part a fit for designs that need to sustain back-to-back reads and writes without the turnaround penalty of older NoBL or QDR architectures. The 250 MHz variant sits above the 200 MHz speed grade (CY7C1321KV18-200BZXCT) — if your timing closure analysis shows margin at 200 MHz, the 250 MHz part buys extra headroom for future clock speed increases or relaxed PCB routing constraints. The Tape & Reel (TR) packaging is the standard delivery for automated pick-and-place; if you are ordering for a prototype run or rework, be aware that a single reel typically holds several hundred units, so single-unit procurement may require a cut-tape or tray option from the distributor.","metaTitle":"CY7C1321KV18-250BZXCT SRAM, 18Mbit, 250 MHz, 165-FBGA","metaDescription":"Cypress CY7C1321KV18-250BZXCT DDR II synchronous SRAM, 18Mbit (512K x 36), 250 MHz clock, 1.7V-1.9V supply, 0°C to 70°C, 165-FBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR)","Technology":"SRAM - Synchronous, DDR II","Memory Size":"18Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Active","Clock Frequency":"250 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1321","Memory Organization":"512K x 36","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$29.5750","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fe7f432065dd58990edfa98b9f769bee.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1321KV18-250BZXCT/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1321KV18-250BZXCT a direct replacement for CY7C1321KV18-200BZXCT?","answer":"Yes, the 250 MHz speed grade is a drop-in replacement for the 200 MHz variant in the same package and footprint, assuming your timing closure can tolerate the faster edge rates."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1321KV18-250BZXCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1321KV18-250BZXCT when reusing this data.
