Product details

4 Mbit SPI DataFlash — wide-VCC, fast page write

The Renesas AT45DB041E-MHN-T is a 4 Mbit serial flash from the DataFlash family, organized as 264-byte pages across 2048 pages. Page writes complete in 8 µs typical, and page erase takes 3 ms — fast enough for code-shadowing or data-logging buffers where the host can poll the status register rather than insert a blocking delay.

Package and board-fit — 8-UDFN with thermal pad

Housed in an 8-lead UDFN with an exposed pad (5x6 mm body), the part is surface-mount and RoHS3-compliant. The exposed pad provides a low thermal-resistance path to the PCB copper — useful if the part is cycled through many write/erase operations in an enclosure without forced airflow.

Frequently asked questions

What is the closest functional alternative to AT45DB041E-MHN-T?

The AT45DB041E-SHNHT-T is the closest peer — same 4 Mbit density, same SPI interface at 85 MHz, same page organization and write timing. The -SHNHT-T comes in an 8-SOIC package rather than the 8-UDFN, so the PCB footprint changes.
