Its 70 ns access time means the CPU can execute code directly from the flash without wait-states on most 16-bit bus controllers running below 14 MHz — useful for boot code or firmware shadowed into RAM at power-up. ## Package and board-fit — 48-TSOP footprint The surface-mount footprint matches legacy 48-pin TSOP layouts, so a board already routed for a 48-TSOP flash can take this part without a respin. ## Write performance and firmware update strategy Write cycle time is 10 µs per word or page — a full 16 Mbit firmware image at 1M words takes roughly 10 seconds to program in-page mode, assuming the controller meets the timing. This is fast enough for field-updatable firmware in networked equipment but slower than SPI NOR; the trade-off is the parallel interface's higher read throughput for code execution. ## Active lifecycle and compliance posture It is ROHS3 compliant, so it clears EU and UKCA regulatory gates without an exemption declaration.","metaTitle":"SST39VF1601-70-4I-EKE-T 16Mbit NOR Flash, 70ns, 48-TSOP","metaDescription":"Microchip Technology SST39VF1601-70-4I-EKE-T 16Mbit parallel NOR flash, 70 ns access time, 2.7-3.6 V, -40 to +85 °C.
