Product details

64 Mbit SPI DataFlash in a compact exposed-pad UDFN

The Renesas AT45DB641E-MHN-Y is a 64 Mbit SPI serial flash memory built on the DataFlash architecture. It communicates over SPI at up to 85 MHz, operates from 1.7 V to 3.6 V, and is specified across the industrial temperature range of -40°C to 85°C. The die sits in an 8-UDFN package with an exposed pad (5x6 mm), which pulls heat into the PCB ground plane and keeps the junction cool during page-write cycles.

Memory organization and write timing

The memory is organized as 264 bytes per page across 32K pages. Page write takes 5 ms typical; a single-byte write completes in 8 µs.

Frequently asked questions

Does AT45DB641E-MHN-Y support SPI mode 0 and what is the maximum clock frequency?

SPI mode 0 (CPOL=0, CPHA=0) is supported. The maximum clock frequency is 85 MHz.

Can AT45DB641E-MHN-Y be used as a replacement for AT45DB641D?

Yes, the AT45DB641E-MHN-Y is the direct successor to the AT45DB641D. It maintains the same 64 Mbit density, 264-byte page organization, and SPI command set. The key difference is the lower supply voltage range (1.7 V to 3.6 V on the E-series vs 2.5 V to 3.6 V on the D-series), which allows operation from a 1.8 V rail.

Where can I buy AT45DB641E-MHN-Y in small quantities or as a sample?

The part is available through independent distribution and is quoted to order against an RFQ. Small quantities and samples can be requested as part of the quote process; minimum order quantities and lead time are confirmed at that time.
