This part is designed for high-throughput buffer and cache applications in networking switches, routers, telecom line cards, and test equipment where back-to-back read/write transactions with zero dead cycles are required. The 167 MHz clock rate yields a peak data rate of 167 million 36-bit words per second per port. For a 512K x 36 configuration, that translates to roughly 6 Gbps of aggregate bandwidth across the two read and two write ports. This speed bin sits below the 200 MHz variant (CY7C1315BV18-200BZC), which offers about 20% higher throughput but draws slightly more active current. If your timing budget has margin at 167 MHz, this part saves a few hundred milliwatts versus the faster bin. ## 165-ball FBGA — footprint and assembly realities It is not hand-solderable with a standard iron. ## Obsolete — sourcing strategy for this part The CY7C1315BV18-167BZC is officially classified as Obsolete by Cypress (now Infineon). No direct pin-compatible replacement has been announced in the QDR II family.","metaTitle":"Cypress CY7C1315BV18-167BZC QDR II SRAM, 18 Mbit, 167 MHz","metaDescription":"Cypress CY7C1315BV18-167BZC is a 18 Mbit QDR II synchronous SRAM organized 512K x 36, clocked at 167 MHz, in a 165-ball FBGA package.","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, QDR 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":"CY7C1315","Memory Organization":"512K x 36","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$29.4900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7ca5041d8d2c4b93eceeb0da7219ce53.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1315BV18-167BZC/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between CY7C1315BV18-167BZC and CY7C1315BV18-200BZC?","answer":"The only parametric difference is the maximum clock frequency: 167 MHz for this part versus 200 MHz for the -200BZC variant.
