The 36-bit word width accommodates 32-bit data plus 4-bit parity or ECC, a common choice in telecom line-card designs. Supply voltage runs from 1.7V to 1.9V, aligning with 1.8V-core logic families. ## Industrial temperature and package — fit for outdoor and factory environments The 165-FBGA (15x17 mm) is a fine-pitch BGA — standard for high-density SRAMs.","metaTitle":"Cypress CY7C2665KV18-550BZI QDR II+ SRAM, 144Mbit, 550 MHz","metaDescription":"Cypress CY7C2665KV18-550BZI QDR II+ synchronous SRAM, 144Mbit (4M x 36), 550 MHz clock, 1.7V–1.9V supply, industrial temp, 165-FBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tray","Technology":"SRAM - Synchronous, QDR II+","Memory Size":"144Mbit","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":"CY7C2665","Memory Organization":"4M x 36","Operating Temperature":"-40°C ~ 85°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/de7713fce0919e9c3cb64ff248f7fd20.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C2665KV18-550BZI/alternatives.json"},"ai":{"faq":[{"question":"What is the clock speed of CY7C2665KV18-550BZI?","answer":"The clock frequency is 550 MHz.
