MX25U1632FM2I02

MX25U1632FM2I02 is Macronix’s 16‑Mbit Serial NOR Flash memory (MX25U family). It provides nonvolatile storage accessible over a serial SPI interface, commonly used for code bootloaders and firmware storage in embedded systems.
Key points:
- Capacity: 16 Mbit (2 MB), 3‑byte addressing for the full density.
- Interface: SPI, with options for faster modes (Dual/Quad I/O in applicable variants).
- Operations: Read, Page Program (typically 256 bytes), Sector erases (e.g., 4 KB) and larger block erases; Write Enable/Disable, and many security/protection features; Deep power‑down mode.
- Speed: Fast read up to around 100–104 MHz clock (depending on variant and mode).
- Voltage: Typical single‑supply range varies by variant (commonly around 2.7–3.6 V; check the exact datasheet for the FM2I02 revision).
- Package: 8‑pin options (SOP/WSON) typical for this family.
- Applications: Firmware storage, boot ROM, and general embedded storage where low footprint serial flash is needed.
For exact electrical characteristics, timing, and packaging, consult the MX25U1632FM2I02 datasheet.
