N25Q128A13BF840E

N25Q128A13BF840E is Micron’s 128‑Mbit serial flash memory in the N25Q family. It provides nonvolatile storage with a Quad SPI (QSPI) interface for high‑throughput data transfer, commonly used for firmware, configuration data, and data logging in embedded systems.
Key features:
- Capacity: 128 Mbit (16 MB)
- Interface: Quad SPI with standard SPI and QPI modes
- Organization: supports page program (typically 256 bytes), sector erase (4 KB), block erase, and chip erase
- Read/erase: fast read options and power-saving/deep power-down modes
- Security: status/config registers, write protection, and other protection options
- Packaging/voltage: available in multiple packages and voltage ranges; exact specs vary by variant
Applications: boot code storage, firmware updates, and persistent data storage in microcontroller-based designs.
