MX25L12845GM2I-10G

MX25L12845GM2I-10G is Macronix’s 128‑Mbit Serial NOR Flash memory for firmware/boot code in embedded systems. It stores code and data and is accessed over SPI with optional dual/quad I/O modes.
Key points:
- Density and organization: 128 Mbit (16 MB); 256‑byte page size; 4 KB sectors; 32 KB/64 KB blocks.
- Interface and speed: SPI with standard, dual I/O, and quad I/O (QPI) modes; high‑speed reads (typical up to fast clock speeds; QPI up to higher rates).
- Voltage and temperature: 2.7–3.6 V supply; Industrial temperature range (-40°C to 85°C) for the M2I variant.
- Operations: Page program, sector/block erase, and chip erase; supports deep power‑down and standard protection features (status/flag registers, Quad Enable, WP/HOLD).
- Endurance and retention: typical endurance ~100k P/E cycles; long-term data retention.
- Package: 8‑pin package suitable for compact boards.
Applications: boot media, firmware updates, and code storage for microcontrollers, microprocessors, and FPGAs. For exact timing, command set, and electrical characteristics, consult the MX25L12845GM2I-10G datasheet.
