It is organized as 1M x 18 and clocks at 300 MHz, delivering a peak read-write bandwidth that suits high-throughput buffer applications — network packet processing, test equipment frame buffers, or cache memory in FPGA-based designs where the bus must sustain back-to-back transactions without dead cycles. The QDR II interface separates read and write data ports, so the controller can issue a read and a write on every rising clock edge, effectively doubling throughput versus a common I/O SRAM at the same frequency. ## Last Buy — plan the LTB order now That means Infineon has issued a final purchase window — once the last-time-buy date passes, the part will no longer be manufactured. The 165-FBGA footprint is shared with other QDR II densities in the family, so a drop-in replacement may exist at a different memory size, but that requires board-level validation. ## 165-FBGA — footprint and rework notes The package is a 165-ball FBGA, 13 x 15 mm body, surface-mount only. For rework, a bottom-side preheat profile that keeps the junction below 220°C is standard; the 0.8 mm ball pitch allows visual alignment with X-ray inspection afterward.","metaTitle":"CY7C1312KV18-300BZC QDR II SRAM 18Mbit 300 MHz 165-FBGA","metaDescription":"Infineon CY7C1312KV18-300BZC 18Mbit QDR II synchronous SRAM, 300 MHz clock, 1M x 18 organization, 165-FBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tray","Technology":"SRAM - Synchronous, QDR II","Memory Size":"18Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Last Time Buy","Clock Frequency":"300 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1312","Memory Organization":"1M x 18","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$30.8500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dea3bcace4592b08079c9a8b90f16dd7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1312KV18-300BZC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1312KV18-300BZC obsolete?","answer":"The part is not yet obsolete but is in Last Buy status — Infineon has announced a final purchase window.
