It runs at up to 85 MHz clock frequency. The part is non-volatile and specified for -40°C to 85°C. ## Page program and erase timing Write-cycle timing is 8 µs for a word write and 6 ms for a full page program. That 6 ms page-write window is the period the host must wait before issuing the next command — relevant when calculating firmware-update time or OTA download budgets. The 512-byte page size matches the sector-erase granularity, so wear-leveling algorithms can align writes to page boundaries without wasted overhead. ## Package and mounting Housed in an 8-pin SOIC with a 3.90 mm body width (0.154\" narrow), surface-mount solders directly to a standard pitch footprint. No heatsink or special pad layout required. ## Lifecycle and sourcing There is no NRND or EOL notice on this part — it qualifies for new BOM entries and production ramp without LTB risk. The part is ROHS3 compliant (lead-free).","metaTitle":"Microchip AT45DQ161-SSHF2B-T 16Mbit SPI Flash, 85 MHz","metaDescription":"Microchip AT45DQ161-SSHF2B-T 16Mbit FLASH, SPI Quad I/O, 85 MHz clock, 2.3V-3.6V supply, 8-SOIC.
