Product details

2 Mbit SPI DataFlash — what it is and where it fits

The Microchip AT45DB021E-SSHNHA-T is a 2 Mbit serial SPI Flash memory organized as 264 bytes per page across 1024 pages. It runs on a single supply from 1.65 V to 3.6 V.

Active lifecycle — no LTB pressure

This part carries an Active product status and ROHS3 compliance. There is no last-time-buy notice, no NRND flag, and no end-of-life bulletins.

Supply voltage and temperature — industrial deployment

The 1.65 V to 3.6 V supply range covers the two most common logic families without a level translator. The -40°C to 85°C operating temperature qualifies it for outdoor telecom cabinets, factory-floor controllers, and motor-drive aux boards where the ambient can climb. Surface-mount assembly on a standard 8-SOIC footprint; the 0.154-inch body width fits most pick-and-place feeders without nozzle change.

Frequently asked questions

What is the exact memory size and organization of AT45DB021E-SSHNHA-T?

It is a 2 Mbit SPI Flash organized as 264 bytes per page across 1024 pages.

Is AT45DB021E-SSHNHA-T RoHS compliant and lead-free?

Yes, it is ROHS3 compliant, which covers the EU RoHS exemption-free requirements.

Can AT45DB021E-SSHNHA-T be used as a direct replacement for AT45DB021B-SSH?

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.

What is the difference between AT45DB021E and AT45DB021D?

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.
