The 85 MHz SPI clock gives a sustained read throughput of roughly 10 MB/s in quad-I/O mode — enough for code shadowing or data logging in an embedded system. The memory array is organized as 528-byte pages rather than the more common 256-byte or 512-byte pages found in many SPI NOR parts. This means a firmware-update routine written for a 512-byte page device needs a buffer-size adjustment to avoid partial-page writes. ## Temperature grade and supply range The SPI interface uses standard mode-0 and mode-3 polarity, and the part supports the standard Read Array (0x0B) and Fast Read (0x0C) commands common across the DataFlash family. ## Active production and compliance Availability and current pricing confirmed at RFQ time.","metaTitle":"Renesas AT45DB321E-SHF-T 32 Mbit SPI Flash, 85 MHz, 8-SOIC","metaDescription":"Renesas AT45DB321E-SHF-T 32 Mbit SPI flash, 85 MHz, 2.3-3.6 V, 8-SOIC.
