It delivers a 70 ns access time and operates from a 1.65V to 1.95V supply, making it one of the few parallel NOR Flash parts that runs directly off a 1.8 V core logic rail without a separate regulator. The 40 µs word/page write cycle time suits firmware-update and parameter-storage tasks in embedded systems that need fast read but can tolerate moderate write speed. The package is lead-free and RoHS3 compliant per the listing. ## 1.65V–1.95V supply — the differentiator Most 16 Mbit parallel NOR Flash parts, including Microchip's own SST39VF1601-70-4I-B3KE-T, require a 2.7V to 3.6V supply. The SST39WF1601-70-4I-MAQE runs from a 1.65V to 1.95V rail, which matches the 1.8 V core supply used in many low-power MCUs and SoCs. If your BOM already has a 1.8 V rail, this part saves a regulator and the associated board area. The trade-off is a slightly higher write-cycle time (40 µs versus 10 µs on the 2.7 V sibling), but for code shadowing and boot storage the read performance is identical at 70 ns. ## Active, RoHS3, and no EOL concern It is ROHS3 compliant. ## BGA footprint and rework considerations The 48-WFBGA (6x4 mm) package uses a fine-pitch ball array. Solder paste stencil aperture and reflow profile must be qualified for lead-free assembly. For rework, a hot-air nozzle matched to the 6x4 mm body and a preheat of 125°C will avoid thermal shock.","metaTitle":"Microchip SST39WF1601-70-4I-MAQE 16 Mbit Parallel NOR Flash","metaDescription":"Microchip SST39WF1601-70-4I-MAQE 16 Mbit parallel NOR Flash in 48-WFBGA. 70 ns access time, 1.65V–1.95V supply, -40°C to 85°C.
