32 Mbit SPI flash in an 8-pin SOIC
The Renesas AT45DQ321-SHFHJ-T is a 32 Mbit SPI flash memory in an 8-SOIC surface-mount package. Memory is organized as 512 bytes per page across 8192 pages, giving you 32 Mbit total. The page write cycle is 4 ms typical, and a byte/word write takes 8 µs — useful numbers to budget when planning firmware update times over the SPI link.
Industrial temp and active lifecycle
RoHS3 compliant, so it meets the current EU restriction directive without needing an exemption review.
