The Renesas AT45DB041E-SHNHT-T is a 4 Mbit serial flash memory with an SPI interface, clocked at 85 MHz. It organizes data as 264 bytes per page across 2048 pages.
The 85 MHz SPI clock rate supports execute-in-place (XIP) code shadowing. The page write cycle is 3 ms, and the byte/word write cycle is 8 µs.
The maximum SPI clock frequency is 85 MHz.
The AT45DB041E-SSHN-T is a functional equivalent with the same 4 Mbit density and 85 MHz clock, but its temperature range is -40°C to 85°C instead of the -40°C to 125°C of the SHNHT variant. For designs that need the extended temperature range, the SHNHT is the correct choice.
Yes. The supply range of 1.65 V to 3.6 V includes 3.3 V, so the part can be driven directly by a 3.3 V SPI master without level shifters.
