MX25L12845GMI-08G

MX25L12845GMI-08G is Macronix’s 128-Mbit Serial NOR Flash memory in an 8-pin package. It provides non-volatile code/data storage for embedded systems via a SPI-compatible interface (standard SPI with Dual/Quad I/O modes). Key points:
- Capacity: 128 Mbit (16 MB)
- Organization: 256-byte pages; 4 KB sectors; 64 KB blocks
- Operations: Read/Fast Read; Page Program; Sector/Block/Chip Erase
- Features: hardware write protection, status register, write enable latch, and deep power-down
- Speed and voltage: up to ~104 MHz clock; operating voltage typically 2.7–3.6 V
- Applications: firmware/code storage and updates, boot memory, data logging in microcontroller-based systems
Good for high-density, low-pin-count non-volatile storage with fast random access and reliable erase/programmable capabilities.
