It clocks at 250 MHz, delivering two data transfers per clock cycle for an effective bandwidth of 18 Gbit/s on a 36-bit bus. This part targets high-throughput, low-latency applications such as network packet buffers, telecom line cards, and high-end test equipment where QDR-style read-write concurrency is not required but raw sequential bandwidth is. The 250 MHz clock frequency is the core timing spec. Because this is a DDR II device, data is clocked on both edges, so the effective data rate is 500 MT/s per pin. With a 36-bit data bus, that yields a peak throughput of 18 Gbit/s (2.25 GB/s). That bandwidth matters when the memory is feeding a high-speed ASIC or FPGA that cannot stall on read data. The trade-off: tighter PCB layout rules for signal integrity at these edge rates — the 165-ball FBGA helps keep trace lengths short. The board must have a dedicated 1.8 V rail with tight regulation (within 100 mV). If your existing design runs on 2.5 V I/O, this part will not drop in without a level-shifter or a separate regulator. Check your power tree before committing the BOM line. Housed in a 165-ball LBGA (13x15 mm FBGA), this is a fine-pitch BGA — ball pitch typical for this density. The footprint requires a multi-layer PCB with microvias or blind vias for fanout. ## Lifecycle — officially obsolete Infineon lists the CY7C1320KV18-250BZC as Obsolete. No last-time-buy window remains open through the manufacturer. For existing production, the only supply channel is the independent distribution market — new-old-stock or surplus inventory.","metaTitle":"CY7C1320KV18-250BZC SRAM, 18Mbit, 250 MHz, DDR II, Obsolete","metaDescription":"Infineon/Cypress CY7C1320KV18-250BZC 18Mbit DDR II+ SRAM, 250 MHz clock, 512K x 36, 1.7V-1.9V, 165-FBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tray","Technology":"SRAM - Synchronous, DDR II","Memory Size":"18Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"250 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1320","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":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/53140c6691acfd2584a2fd1e9086db4f.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1320KV18-250BZC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1320KV18-250BZC when reusing this data.
