MT25QL512ABB8ESFE01-2SIT

MT25QL512ABB8ESFE01-2SIT is Micron’s MT25QL series 512‑Mbit Quad SPI (QSPI) flash memory. It provides 64 MB of nonvolatile storage for embedded systems, ideal for firmware boot code and data storage. Key points:
- Organization: 64M × 8; uses a serial SPI interface with Quad SPI/QPI modes for higher throughput.
- Operations: Read/Fast Read, Page Program (256 bytes), and erase options (4 KB, 8 KB, 64 KB sectors/blocks, plus Chip Erase).
- Features: standard write protection and security options; supports various power/voltage and timing modes in line with MT25QL devices.
- Packaging/grade: suffix typically indicates packaging and temperature grade (often industrial).
For exact electrical specs (voltage range, speed grades, endurance), timing, and packaging details, refer to the MT25QL512ABB8ESFE01-2SIT datasheet and product brief.
