Its 70 ns access time means the CPU can execute code directly from this flash (eXecute-In-Place) without copying to RAM first — a common pattern in boot firmware and real-time control applications where every microsecond of latency matters. ## Supply rails and temperature grade The 10 µs word/page write cycle is fast enough to handle firmware updates and calibration data writes without the multi-millisecond sector-erase penalty typical of NAND flash. For a 16 Mbit part, a full-chip erase completes in well under a second, making field-upgradeable firmware practical. Housed in a 48-TFSOP (0.724\" body width, 18.40 mm) surface-mount package, also referred to as 48-TSOP. The 0.50 mm pin pitch is hand-solderable with a fine-tip iron and flux, though a hot-air station makes rework easier. The footprint is standard across the SST39VF series, so a single PCB layout can serve multiple density options.","metaTitle":"SST39VF1681-70-4C-EKE 16Mbit Parallel NOR Flash, 70 ns","metaDescription":"Microchip SST39VF1681-70-4C-EKE 16Mbit parallel NOR flash, 70 ns access, 2.7-3.6V, 48-TSOP.
