This is a high-bandwidth memory part designed for networking gear, ASIC testers, and telecom line cards where the bus needs back-to-back read and write throughput without dead cycles — QDR II+ eliminates the bus-turnaround penalty that conventional SRAMs incur. Expect limited availability and date-code variance — any trays on the spot market are pulled from last-time-buy stock or overruns. Sourcing this part means qualifying the supplier's screening process for counterfeit risk and verifying the date code matches your assembly reflow profile (the 165-FBGA is moisture-sensitive). The 165-FBGA (13x15 mm) footprint is a fine-pitch BGA — 1.0 mm ball pitch, 165 balls. That means a multi-layer PCB with via-in-pad or microvia escape routing is the norm.","metaTitle":"Cypress CY7C25652KV18-550BZXI 72Mbit QDR II+ SRAM, 550 MHz","metaDescription":"Cypress CY7C25652KV18-550BZXI 72Mbit QDR II+ synchronous SRAM, 2M x 36, 550 MHz clock, 1.7V-1.9V, -40°C to 85°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, QDR II+","Memory Size":"72Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Active","Clock Frequency":"550 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C25652","Memory Organization":"2M x 36","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$315.0500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/438a7d74bdeae93b13fd3b69bda25679.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C25652KV18-550BZXI obsolete?","answer":"Yes, the CY7C25652KV18-550BZXI is listed as Obsolete.
