128 Mbit parallel NOR flash for automotive code-shadowing
The S26KS128SDABHB030: The 1.7 V core supply and AEC-Q100 qualification target automotive ECU designs where code executes directly from flash (XIP) or shadows to RAM at power-up.
AEC-Q100 grade and thermal envelope
Qualified to AEC-Q100, the part meets the stress, reliability, and PPAP requirements for automotive supply chains — engine control units, transmission controllers, and chassis-domain modules.
Parallel interface and board-fit considerations
The 24-ball FBGA package (0.80 mm pitch typical for this density class) routes to a standard parallel NOR flash footprint. The byte-wide 8-bit data bus matches the memory controller on many automotive MCUs and MPUs — no need for a serial-to-parallel bridge or extra GPIOs for address demux. The 96 ns random-access time sets the initial read latency for code fetch after reset; once the burst engine engages at 100 MHz, sequential reads sustain at the clock rate. The 1.7 V supply rail must be within ±5% for reliable read and program operations — a clean LDO or buck output dedicated to the flash rail avoids read-disturb issues.
