The Microchip AT45DB021E-SSHNHA-T is a 2 Mbit serial SPI Flash memory organized as 264 bytes per page across 1024 pages.
There is no last-time-buy notice, no NRND flag, and no end-of-life bulletins.
Surface-mount assembly on a standard 8-SOIC footprint; the 0.154-inch body width fits most pick-and-place feeders without nozzle change.
It is a 2 Mbit SPI Flash organized as 264 bytes per page across 1024 pages.
Yes, it is ROHS3 compliant, which covers the EU RoHS exemption-free requirements.
The AT45DB021E is the later-generation die with a wider supply range (1.65 V to 3.6 V vs the B-series typical 2.7 V minimum). Pinout and SPI command set are backward-compatible, but verify the Vcc minimum in your design before dropping it in as a drop-in swap.
The E-series operates down to 1.65 V, while the D-series typically required a minimum of 2.5 V. The E also offers a faster 70 MHz SPI clock versus the D's 66 MHz. Both share the same 8-SOIC footprint and page size.
