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.
The exposed pad also improves mechanical stability in vibration-prone environments.
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.
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.
Page write completes in 8 µs and a full page erase in 3 ms, based on the datasheet specifications.
