The 20 µs page write time (word or page) means a full 256-byte page programs in the same 20 µs, not multiplied by the byte count, so firmware updates or parameter writes complete quickly. This write speed is typical for the SST25 family and keeps the part competitive for non-volatile storage where the host processor can pipeline the SPI transaction. If your board sees under-hood heat or extended cold soak, this temperature grade is the one you want.","metaTitle":"SST25VF020-20-4I-SAE 2Mbit SPI Flash, 20 MHz, 8-SOIC","metaDescription":"Microchip SST25VF020-20-4I-SAE 2Mbit SPI Flash, 20 MHz clock, 2.7-3.6V supply, -40°C to 85°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":"SST25","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Series":"SST25","Package":"Tube","Technology":"FLASH","Memory Size":"2Mbit","Memory Type":"Non-Volatile","Memory Format":"FLASH","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Clock Frequency":"20 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI","Voltage - Supply":"2.7V ~ 3.6V","Memory Organization":"256K x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-SOIC","Write Cycle Time - Word, Page":"20µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.00000","currency":"USD"},{"qty":25,"price":"$0.96000","currency":"USD"},{"qty":100,"price":"$0.90000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/95c21d1a58c3319e59b87419e1739b2a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is there a direct drop-in replacement for SST25VF020-20-4I-SAE?","answer":"The closest functional sibling is the SST25VF010A-33-4I-QAE, which is a 1 Mbit device (half the density) in the same SST25 family with a 33 MHz clock, but it comes in a different package (8-WSON).
