128 Mbit NOR Flash with Quad SPI for Firmware Storage
The S25FL128SAGMFV010 is a 128 Mbit (16M x 8) NOR Flash memory from Infineon's FL-S series, organized as non-volatile storage with an SPI Quad I/O interface that clocks at 133 MHz. The Quad I/O interface reads four bits per clock cycle, pushing the effective throughput well beyond a standard SPI bus — useful for code shadowing or fast firmware updates where the CPU executes directly from the flash.
Industrial Temperature Grade and Package Fit
Rated for -40°C to 105°C ambient (TA), this part suits outdoor telecom, automotive cabin, or industrial motor-drive enclosures where the internal air temperature stays below the 105°C ceiling. Housed in a 16-SOIC wide-body package (7.50 mm body width), the footprint matches the JEDEC MO-119 standard — a common layout for NOR Flash on medium-complexity PCBs that avoids the finer pitch of BGA packages. Supply voltage spans 2.7 V to 3.6 V, which aligns with 3.3 V logic rails and allows the flash to share the same power plane as the host MCU or SoC without a separate regulator.
Active Lifecycle and Sourcing Reality
RoHS3 compliant and supplied in tray packaging. The base product number S25FL128 covers the family; the full suffix decodes the specific temperature range, package, and speed grade.
