It clocks at 167 MHz with a parallel interface, delivering double-data-rate transfers on both edges of the clock for high-bandwidth buffer applications — typically network packet processing, base station line cards, or test equipment where low-latency temporary storage is critical. ## 167 MHz clock and DDR-II bus — what the speed rating buys you At 167 MHz, the DDR-II interface transfers data at 333 MT/s per pin. For an 18-bit-wide bus, that yields roughly 6 Gbit/s raw bandwidth — enough to feed a high-end FPGA or network processor without stalling. The synchronous architecture eliminates the dead cycles associated with asynchronous SRAM, so back-to-back reads and writes sustain full throughput. If your design needs higher density or a wider bus, the CY7C1318 family includes 36Mbit and x36 variants, but the footprint and supply voltage differ — verify compatibility before swapping. Infineon lists the CY7C1318BV18-167BZC as obsolete. If you are qualifying a replacement, expect to evaluate a pin-compatible DDR-II SRAM from another vendor with the same 165-FBGA footprint and 1.8V supply; the base product number CY7C1318 may have later speed or temperature variants still active, but the -167BZC suffix specifically is end-of-life. ## 165-FBGA footprint and layout notes The 165-ball FBGA measures 13x15 mm with a 1.0 mm ball pitch. Surface-mount reflow requires a standard lead-free profile; the package is moisture-sensitive, so a bake may be needed if the tray seal is broken. Decoupling should follow the datasheet recommendation — typically a 0.1 µF ceramic per supply pin plus a bulk 10 µF on the board. The narrow 1.7V to 1.9V supply range means the 1.8V rail must be well-regulated; a 3% tolerance regulator keeps the SRAM inside its operating window.","metaTitle":"CY7C1318BV18-167BZC 18Mbit DDR-II SRAM, 167 MHz, 165-FBGA","metaDescription":"Infineon CY7C1318BV18-167BZC synchronous DDR-II SRAM, 18Mbit (1M x 18), 167 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":"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":"167 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":"$31.9600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a07109beba6db9551214c97b02684751.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1318BV18-167BZC/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for CY7C1318BV18-167BZC?","answer":"Infineon has not published an official successor order code for this specific speed and temperature grade. A replacement would need to be a pin-compatible DDR-II SRAM in the 165-FBGA package with 1.8V supply and 167 MHz or faster clock.
