S25FS256SDSBHM203

Active and preferred

The S25FS256SDSBHM203 is a 256 Mbit (32 MB) automotive-grade, AEC-Q100 qualified serial NOR flash memory operating at 1.8 V with MIRRORBIT™ Eclipse architecture for fast program and erase. Supporting SPI multi-I/O in single, dual, quad, and DDR modes, it achieves up to 80 MBps read speeds. Flexible sector options, strong data protection, 100,000 program-erase cycles minimum, and 20-year data retention make it ideal for code shadowing, XIP, and embedded automotive uses.
