Automotive NOR Flash for ECU firmware storage
The S25FL128SAGBHBA00: It stores firmware and calibration data in engine control units, transmission controllers, ADAS modules, and body-domain ECUs. The 133 MHz Quad SPI interface supports fast read for execute-in-place (XIP) boot, and the 2.7V to 3.6V supply range covers both 3.0V and 3.3V automotive power rails.
133 MHz Quad SPI — what it buys the boot path
Clock frequency of 133 MHz over the Quad SPI bus. The SPI - Quad I/O interface is backward-compatible with standard SPI.
Temperature range and AEC-Q100 — where it runs
If your design targets a passenger vehicle, this grade saves a qualification cycle.
24-BGA footprint — layout notes
Packaged in a 24-ball BGA (8x6 mm body), surface-mount only. The 0.8 mm ball pitch is layout-friendly for a two-layer board, but route the Quad SPI signals with matched trace lengths to maintain timing margin at 133 MHz. Decouple with a 100 nF ceramic close to each supply ball; the 2.7V-3.6V range gives some headroom for supply droop during read bursts.
