The write cycle time is also 70 ns, so read and write timing are symmetrical. ## Sourcing and lifecycle It is available through independent distribution channels and can be quoted to order against an RFQ. No official second-source or direct replacement is listed in the available records, but the 28-SOP pinout is common across many 256Kbit parallel SRAMs from other manufacturers — a functional equivalent can be qualified by comparing the timing and supply specs.","metaTitle":"R1LV5256ESP-7SI#B0 SRAM 256Kbit Parallel 70 ns 28-SOP","metaDescription":"R1LV5256ESP-7SI#B0 256Kbit SRAM, 70 ns access, parallel interface, -40°C to 85°C, 2.7V-3.6V supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Bulk","Technology":"SRAM","Access Time":"70 ns","Memory Size":"256Kbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"28-SOIC (0.330\\\", 8.40mm Width)","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"2.7V ~ 3.6V","Memory Organization":"32K x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"28-SOP","Write Cycle Time - Word, Page":"70ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.79","stockQuantity":0,"priceTiers":[{"qty":80,"price":"$3.79000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1654418884eacb27babcdb689c8602f3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is R1LV5256ESP-7SI#B0 suitable for -40°C to 85°C operation with 2.7V supply?","answer":"Yes, the part is rated for the full industrial temperature range at supply voltages as low as 2.7V.
