Organized as 1M x 18, it is designed for high-throughput buffer applications where the bus needs an 18-bit word width. At 200 MHz clock with DDR II signaling, the part delivers back-to-back read/write transactions without dead cycles between bursts. That matters when the FPGA or ASIC on the other side of the bus is running a 200 MHz core clock and cannot afford wait states. The 1M x 18 organization gives you 1 M deep by 18-bit wide storage — enough for a moderate-sized packet buffer or a lookup table that needs single-cycle random access. ## 165-ball FBGA — what the package means for assembly and rework The surface-mount mounting type is standard for this class of SRAM, but the footprint is not compatible with older 100-pin TQFP or 119-ball BGA SRAMs. If you are supporting a legacy board that uses this exact SRAM, expect to pay a premium for the remaining stock, and plan a redesign to a current-generation DDR II+ or QDR SRAM if the product has a multi-year service life ahead.","metaTitle":"Cypress CY7C1318CV18-200BZXC 18Mbit DDR II SRAM, 200 MHz","metaDescription":"Cypress CY7C1318CV18-200BZXC 18Mbit synchronous DDR II SRAM, 200 MHz clock, 1M x 18 organization, 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":"200 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1318","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":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8a42d4aec09ef04d08347de8b78a9f5c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C1318CV18-200BZXC obsolete?","answer":"Yes, the CY7C1318CV18-200BZXC is listed as Obsolete.
