S25FL164K0XMFI010

The S25FL164K0XMFI010 is a 16‑Mbit Serial NOR Flash memory from Spansion/Cypress (now part of Infineon) used for non‑volatile firmware and data storage in embedded systems. It provides an SPI (Serial Peripheral Interface) interface (standard SPI with options for higher‑speed/Quad I/O on compatible variants) and uses 3‑byte addressing for its 16‑Mbit array.
Key points:
- Capacity and organization: about 2 MB of flash memory; typically organized into 256‑byte pages, with erasable sectors (commonly 4 KB) and larger blocks (e.g., 64 KB) for erasing.
- Commands and access: supports typical SPI flash operations—read, fast read, page program, sector/block erase, write enable, and power/low‑power modes.
- Performance: fast read up to around 100+ MHz clock rate (often specified up to 104 MHz on many S25FL parts).
- Reliability and protection: includes status register, write protection/block protection features, and power-down/deep‑power‑down modes.
- Applications: firmware storage, bootloaders, and general non‑volatile data storage in microcontroller systems.
Note: exact packaging, pinout, and feature set can vary by revision; consult the datasheet for the precise variant (010 suffix) you have.

Key features of S25FL164K0XMFI010:
