256 Mbit parallel NOR Flash for code-shadowing and data logging
The S26KL256SDABHA030 is a 256 Mbit parallel NOR Flash from Infineon's HyperFlash™ KL family, organized as 32M x 8 bits. It is designed for high-reliability embedded systems that need fast random-read access and a simple parallel interface. With a 96 ns initial access time and a 100 MHz clock for burst reads, this part suits applications like automotive ECU code-shadowing, industrial boot memory, and data logging where deterministic read latency matters.
Supply rail and temperature grade
The AEC-Q100 qualification (Grade 3 implied by the temperature range) means it has passed the reliability stress tests required for automotive-grade components.
Package and board integration
Housed in a 24-ball FBGA package (Bulk delivery), the footprint is compact — typical 6×8 mm body with 0.80 mm ball pitch. The parallel interface requires 8 data lines, address lines, and control signals (CE#, OE#, WE#), so the PCB fan-out is manageable on a 4-layer board. The surface-mount package is MSL 3 typical for FBGA NOR Flash; bake and reflow profiles should follow the JEDEC J-STD-020 standard for the specific body size.
