It stores firmware images, bootloaders, configuration tables, or data logs in embedded systems where a parallel NOR Flash would waste board area and I/O pins. ## 50 MHz SPI — fast enough for most MCU buses At 50 MHz the SPI clock is fast enough to keep up with most microcontroller QSPI or SPI peripherals without needing a high-speed layout. The interface stays single-bit SPI, so no quad-I/O complexity; the trade-off is that sustained read throughput tops out around 6 MB/s, which is adequate for code shadowing from Flash to RAM at boot but not for streaming video. ## Commercial temp range — indoor use only It will not survive an automotive dashboard in summer or an outdoor telecom cabinet in winter. If your design needs -40°C to 85°C, look at the SST25VF020B-80-4I-SAE-T sibling in the same series, which carries the industrial temperature grade. ## 8-WDFN with exposed pad — thermal relief, but plan your rework The 8-WDFN exposed-pad package (also called 8-WSON 6x5 mm) gives a solid thermal path to the PCB ground plane, which helps when the part is running continuous read cycles. But the leads are hidden under the package body — you will need a hot-air station to remove or replace it. The exposed pad also means the footprint needs a thermal via stitch under the part; without it, the pad floats thermally and the part runs hotter than expected. ## Active lifecycle — no obsolescence worry For dual-sourcing, the SST26VF016BT-104I/MF is a quad-I/O pin-compatible upgrade that runs at 104 MHz, but it uses a different command set — firmware changes are required.","metaTitle":"Microchip SST25VF016B-50-4C-QAF-T 16 Mbit SPI Flash, 50 MHz","metaDescription":"Microchip SST25VF016B-50-4C-QAF-T 16 Mbit SPI Flash memory, 50 MHz clock, 2.7V-3.6V supply, 8-WDFN package, 0°C to 70°C.","metaKeywords":null},"attributes":{"series":"SST25","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Series":"SST25","Package":"Tape & Reel (TR); Cut Tape (CT)","Technology":"FLASH","Memory Size":"16Mbit","Memory Type":"Non-Volatile","Memory Format":"FLASH","Mounting Type":"Surface Mount","Package / Case":"8-WDFN Exposed Pad","Clock Frequency":"50 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI","Voltage - Supply":"2.7V ~ 3.6V","Memory Organization":"2M x 8","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"8-WSON (6x5)","Write Cycle Time - Word, Page":"10µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.18","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.18000","currency":"USD"},{"qty":25,"price":"$2.08840","currency":"USD"},{"qty":100,"price":"$2.00340","currency":"USD"},{"qty":2000,"price":"$2.00341","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f106c6e68ff49968b6a8193376ed0f9a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SST25VF016B-50-4C-QAF-T RoHS compliant?","answer":"Yes, it is ROHS3 compliant per the manufacturer's listing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SST25VF016B-50-4C-QAF-T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SST25VF016B-50-4C-QAF-T when reusing this data.
