Frequently asked questions
Where can I buy AT45DB021E-SSHN-B and how do I get a price?
This part is sourced through independent distribution. Submit an RFQ for current availability and pricing; lead time and price are confirmed at quote time.
What is the write cycle time per page for AT45DB021E-SSHN-B?
The page write time is 3 ms; the word write time is 8 µs.
Can AT45DB021E-SSHN-B be used as a replacement for AT45DB021E-SSHN-T?
Yes. The -B (tube) and -T (tape-and-reel) variants share the same die, same 8-SOIC package, same 70 MHz SPI interface, same 1.65 V–3.6 V supply, and same 264-byte page organization. The only difference is the delivery medium.
Is AT45DB021E-SSHN-B pin compatible with AT45DB021D?
The AT45DB021E series is the successor to the AT45DB021D and maintains the same 8-pin SOIC footprint and SPI pinout. Verify the exact supply voltage and timing parameters against your design, but the mechanical and interface compatibility is preserved across the E and D generations.
Does AT45DB021E-SSHN-B support quad SPI mode?
The listed interface is standard SPI. The DataFlash family does not include quad-SPI support on this part; it uses a single SPI bus with dedicated chip-select, clock, data-in, and data-out lines.
