The Microchip AT45DB041E-SHNHA-T is a 4 Mbit serial NOR flash memory organized as 264 bytes per page across 2048 pages. It communicates over an SPI bus at up to 85 MHz. Page write completes in 8 µs and a full page erase in 3 ms.
Yes. The supply voltage range is 1.65 V to 3.6 V, so it operates directly on a 1.8 V rail without external regulation.
The AT45DB041E-SHNHT-T is the same 4 Mbit SPI flash with an extended temperature range of -40°C to 125°C, otherwise identical specs. The AT45DB041E-SSHN-T matches the -40°C to 85°C range but in a standard 8-SOIC narrow body — verify footprint compatibility before substituting.
The AT45DB041E is the newer generation with an 85 MHz SPI clock and lower active power versus the earlier AT45DB041D. The E-series also supports a wider supply range down to 1.65 V. The datasheet for AT45DB041E-SHNHA-T covers the full electrical specifications.
Yes — the part is available in Cut Tape (CT) quantities, suitable for prototyping and low-volume builds. Quoted to order against an RFQ.
