MX25U1632FM2I02

MX25U1632FM2I02 is Macronix’s 16‑Mbit serial NOR flash memory (MX25U family). It is used to store code or data in embedded systems and is accessed over SPI.
Key points:
- Interface: SPI-compatible, with options for high-speed Dual/Quad I/O modes
- Supply voltage: 2.7–3.6 V (industrial variants available)
- Package/ temp: 8‑pin package, industrial temperature range (-40°C to +85°C)
- Memory operations: Read/Fast Read, Page Program (typically 256 bytes), Sector Erase (e.g., 4 KB), Block Erase (e.g., 64 KB), Chip Erase; standard WEL/Write protections and status/config registers
- Features: hardware write protection, status/config registers, security features; supports memory-mapped (XIP) mode on some configs
- Applications: boot code storage, firmware updates, data logging in embedded systems
Note: For exact timings, sector/block sizes, and command set details, refer to the MX25U1632FM2I02 datasheet.
