The 167 MHz clock rate supports high-bandwidth read and write operations with double-data-rate transfer on each clock edge. At 167 MHz, the DDR II interface delivers a data rate of 333 million transfers per second on an 18-bit-wide bus. That bandwidth suits packet buffers and look-up tables in switches and routers where the memory must keep up with the line rate. The 1.7V to 1.9V core supply is tighter than a standard 1.8V rail — the regulator needs to hold within that window under load transients. The 165-ball FBGA (15x17 mm) footprint requires a multi-layer PCB with controlled impedance traces for the clock and data lines.","metaTitle":"Cypress CY7C1518V18-167BZC 72Mbit DDR II SRAM, 167 MHz","metaDescription":"Cypress CY7C1518V18-167BZC 72Mbit synchronous DDR II SRAM in 165-FBGA, 167 MHz clock, 1.7V-1.9V supply.","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":"72Mbit","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":"CY7C1518","Memory Organization":"4M x 18","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"165-FBGA (15x17)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3c3efccd1ce1508f16838b9f4aacc9c9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1518V18-167BZC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1518V18-167BZC obsolete?","answer":"Yes, the lifecycle status for CY7C1518V18-167BZC is Obsolete.
