MX25L12845GMI-08G

MX25L12845GMI-08G is Macronix’s 128‑Mbit serial NOR flash memory with SPI-compatible interface. It’s designed for firmware/code storage and data in embedded systems, offering higher density than EEPROM in a small package.
Key points:
- Capacity and organization: 128 Mbit (16 MB); 256-byte page program; sector/block granularity (e.g., 4 KB sectors; larger blocks available).
- Interfaces: Standard SPI and scalable Quad I/O/dual-SPI/QPI modes for higher throughput.
- Volt/temperature: 2.7–3.6 V operation; industrial temperature range (-40 to 85°C).
- Endurance/retention: Typical erase/program endurance ~100,000 cycles; data retention ~20 years.
- Package: 8-pin variant (08G code) suitable for compact boards; typical pinout includes CS, CLK, DI, DO, WP, HOLD, VCC, GND.
- Features: supports typical erase commands, resume/power-down options, and security features (e.g., write protection).
Applications: boot ROMs, firmware storage, look‑up tables, and code/data storage in microcontrollers and embedded devices.
Note: Always verify exact specs in the current Macronix datasheet for the specific lot and package.
