The S25FL116K0XMFN011: This means the manufacturer no longer produces the part, and no official last-time-buy window remains open. Any procurement for this BOM line runs through independent surplus or broker channels — the date-code and lot traceability become the primary authenticity screen.
16 Mbit NOR Flash with 108 MHz SPI Quad I/O
The S25FL116K0XMFN011 is a 16 Mbit (2M x 8) NOR Flash memory from the FL1-K series, organized as 2,097,152 bytes accessed via a SPI bus supporting Quad I/O reads at up to 108 MHz. The 108 MHz clock rate on the Quad I/O interface delivers a sequential read throughput that suits code-shadowing or data-logging applications where the host MCU can keep the bus busy. The write cycle time is specified at 3 ms per word or page. For a 256-byte page buffer, this means a full-page program completes in 3 ms typical — a figure that matters when calculating firmware-update or data-logging latency in the field.
SOIC-8 footprint and temperature grade
Packaged in an 8-SOIC (0.209-inch body width, 5.30 mm) with surface-mount termination. The supplier device package is 8-SOIC. The 5.30 mm-wide SOIC footprint is a common NOR Flash outline — the board layout matches industry-standard land patterns, so a replacement part with the same package and pinout can drop in without a board spin, provided the signal timing and supply rails align. This covers engine-bay, outdoor telecom cabinet, and factory-floor deployments where the ambient sees sustained heat.
Provenance and compliance
For an obsolete part sourced through independent distribution, the date-code and top-mark laser etch are the first authenticity check — a mismatched font or inconsistent package cavity flash flags a potential counterfeit. RoHS compliance is standard for this series but should be confirmed on the specific date-code lot at RFQ.
