MX25L12845GM2I-10G

MX25L12845GM2I-10G is Macronix’s 128‑Mbit serial NOR flash memory with a SPI‑compatible interface. It stores firmware and other non‑volatile data for embedded systems and is organized to support page, sector, and block operations.
Key points:
- Capacity: 128 Mbit (16 MB).
- Interface: SPI-compatible, with optional dual/quad I/O (DQ) modes for higher throughput.
- Organization: 256-byte page programming; sectors (e.g., 4 KB) and blocks (e.g., 64 KB); full-chip erase available.
- Performance: supports standard and fast read; Quad I/O read modes enable higher data transfer rates.
- Power: operates from a 2.7–3.6 V supply; includes low-power modes (e.g., Deep Power‑Down).
- Endurance/retention: NOR flash characteristics (cycles in the tens of thousands to millions; long data retention).
- Applications: microcontroller boot code, FPGA/SoC configuration storage, and other embedded non‑volatile storage needs.
The -10G suffix denotes a specific speed/temperature grade within the MX25L12845 family; consult the datasheet for exact electrical, timing, and packaging details.
