Product details

The Microchip AT45DB021E-SSHNHC-T is a 2Mbit serial SPI DataFlash memory built on a non-volatile FLASH technology. It organizes its memory into 264 bytes per page across 1024 pages.

70 MHz SPI and write timing — what drives the BOM decision

The 70 MHz SPI clock is the headline throughput spec. The write cycle time — 8 µs for a page program and 3 ms for a page erase — sets the floor for how long a firmware update takes.

The AT45DB021E-SSHNHC-T is an active, current-production part. If you need a firm price and delivery for a BOM line, submit an RFQ and we will come back with the current picture from our multi-source channel.

Frequently asked questions

Is AT45DB021E-SSHNHC-T obsolete or end-of-life?

No, it carries an Active product status from Microchip. There is no current end-of-life notice, so it is suitable for new designs and production builds.

What is a direct equivalent or replacement for AT45DB021E-SSHNHC-T?

The AT45DB021E-SSHNHA-T is functionally identical — same 2Mbit density, 70 MHz SPI, 8-SOIC package, and supply range. Verify the exact suffix differences with your distributor for drop-in compatibility.

What is the write cycle time for AT45DB021E-SSHNHC-T?

The page write cycle time is 8 µs and the page erase cycle time is 3 ms. These times determine firmware-update throughput for a multi-page update.

Is AT45DB021E-SSHNHC-T RoHS compliant?

Yes, it is ROHS3 compliant, meeting the latest EU restriction-of-hazardous-substances requirements.
