- Interface: SPI (standard); some variants support Dual/Quad I/O modes
- Organization: 4 KB sectors; larger blocks (e.g., 64 KB) for erasure
- Operations: Read, Fast Read, Page Program (typically 256 bytes), Sector/Block/Chip Erase
- Commands: common flash commands (WREN, WRDI, RDID/RDSR/WRSR, etc.)
- Endurance/Retention: typical program/erase endurance around 100,000 cycles per sector with multiyear data retention
- Voltage: usually 2.7–3.6 V (single-supply); some devices offer other voltage ranges
- Temperature: industrial and extended temperature options available
- Package: commonly 8-pin package (SOIC/TSOP variants)
