It's a volatile memory part from Infineon (formerly Cypress), built for high-bandwidth parallel data paths where every clock edge moves data — think network switch buffers, base station line cards, and FPGA cache memory in telecom or industrial control backplanes. The supply rail is 1.7V to 1.9V, which aligns with 1.8V-core logic families — no extra regulator needed if your FPGA or ASIC already runs a 1.8V bank. The 165-FBGA package (13x15 mm) demands a controlled reflow profile — the 0.80 mm ball pitch is layout-friendly for a 4-layer board, but the centre ground pad needs a thermal via array under the BGA footprint to pull heat out of the die. Infineon lists the CY7C1318CV18-200BZI as Obsolete. No official successor part number is published on the product page — the base number CY7C1318 has no active direct drop-in listed by the manufacturer. We source and quote to order against your quantity — confirm the package (Tray, 165-FBGA) and temperature grade match your assembly before committing. ## DDR II SRAM — why the double-data-rate matters DDR II means data transfers on both rising and falling clock edges, effectively doubling throughput per pin compared to single-data-rate SRAM at the same clock frequency. At 200 MHz, the data rate is 400 MT/s per I/O — enough to feed a 16-bit or 18-bit bus without a wide parallel interface. The 1M x 18 organization gives you 18 data pins with byte-wide granularity — useful for parity or ECC schemes where an extra bit per byte is needed, or for 18-bit DSP data words.","metaTitle":"CY7C1318CV18-200BZI SRAM – Obsolete, 18Mbit, 200 MHz","metaDescription":"CY7C1318CV18-200BZI is an obsolete 18Mbit DDR II SRAM from Infineon. 200 MHz clock, 1.7V-1.9V supply, -40°C to 85°C.","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":"-40°C~85°C(TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$30.9500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9277bd03f2b92ad82091b2611cd1c9ce.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1318CV18-200BZI/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1318CV18-200BZI compatible with 1.8V systems?","answer":"Yes.
