256 Mbit parallel NOR flash for automotive code storage
The S26KL256SDABHM030: That temperature range covers under-hood and engine-bay deployments where the flash must retain code through hot-soak and cold-crank events. Organised as 32M x 8 bits, the device uses a parallel interface running at 100 MHz with a 96 ns initial access time — the random-read latency is low enough for direct code execution (XiP) from flash without a shadow copy to RAM, saving BOM cost and board space.
Infineon lists the S26KL256SDABHM030 as Active.
Parallel interface and supply voltage — board-fit details
Packaged in a 24-ball FBGA, surface-mount. The footprint is standard for the HyperFlash™ KL family; the ball pitch and layout match the reference design in Infineon's application notes for the Traveo and AURIX microcontroller families.
