Package and board-fit for the 16-SOIC wide-body
The S25FL128LAGMFM003: The 16-pin SOIC-300mil land pattern is shared across many SPI Flash parts, so a single board layout can accommodate this device and its pin-compatible siblings without a respin. Tape & Reel packaging (TR) means the reels feed directly into a pick-and-place machine; store them in a dry cabinet if the reel label shows a moisture-sensitivity level (MSL) of 3 or higher, typical for SOIC packages.
133 MHz Quad I/O — what the interface delivers
The SPI Quad I/O and QPI interface clocks at 133 MHz, which translates to a sustained read throughput of 532 Mbit/s in quad-output mode — enough to feed an automotive MCU executing XIP (eXecute In Place) without a separate RAM cache for code storage. The 128 Mbit density (16M x 8 organization) holds a full firmware image plus a data-logging partition for a typical engine or transmission ECU.
Automotive temperature grade and AEC-Q100 qualification
The AEC-Q100 qualification (Grade 1) means it passed the stress tests for high-temperature operating life, temperature cycling, and ESD robustness — a requirement for any IC used in safety-critical or long-life vehicle systems. The FL-L series is Infineon's automotive NOR Flash family, designed for 15+ year service life in powertrain, chassis, and body electronics.
