Product details

2 Mbit SPI DataFlash with 70 MHz clock

The Microchip AT45DB021E-MHN2B-T is a 2 Mbit serial Flash memory organized as 264 bytes per page across 1024 pages, accessed through an SPI interface running at up to 70 MHz. It operates from a single supply between 1.65 V and 3.6 V. The memory is non-volatile, formatted as FLASH, and rated for the industrial temperature range of -40°C to 85°C.

Package and footprint

Housed in an 8-UDFN with an exposed pad (supplier package 8-UDFN 5x6), the part is surface-mount and requires a thermal pad connection on the PCB for heat dissipation during sustained write cycles. The exposed pad also improves mechanical stability in vibration-prone environments.

Frequently asked questions

Is AT45DB021E-MHN2B-T compatible with 1.8V operation?

Yes, the supply range of 1.65 V to 3.6 V covers 1.8 V nominal operation directly, so no level shifting is needed on the power rail.

Is AT45DB021E-MHN2B-T compatible with 3.3V?

Yes, the 3.6 V maximum supply covers 3.3 V rails with 0.3 V of headroom, making it suitable for standard 3.3 V logic systems.

What is the write cycle time for AT45DB021E?

Page write completes in 8 µs and a full page erase in 3 ms, based on the datasheet specifications.
