S25FL164K0XMFI010 is a 16‑Megabit serial NOR Flash memory from the Spansion/Cypress S25FL family. It stores code and data in embedded systems and is accessed over an SPI interface (with fast/dual/quad options available on variants). Key features:
- Capacity: 16 Mb (2 MB) of non-volatile storage
- Organization: 2,097,152 bytes; 256-byte pages; 4 KB sectors; 64 KB blocks
- Operations: Read, Fast Read, Page Program (256 bytes), Sector/Block Erase, Chip Erase
- Control: Write Enable/Disable, Read/Write Status Registers, block/sector protection, security features
- Power: Low-power modes, including Deep Power-Down
- Throughput: High-speed clock (typical fast read up to tens of MHz, depending on configuration); supports multiple I/O modes on supported variants
Common uses: firmware/boot code storage, data logging, and firmware updates in embedded systems and automotive/industrial equipment. For exact electrical characteristics, timing, and command set, consult the S25FL164K0XMFI010 datasheet.
