N25Q064A13EF640E

N25Q064A13EF640E is a 64‑Mbit serial NOR flash memory from Micron’s N25Q family. It provides non‑volatile firmware/data storage for embedded systems and is accessed via a Quad I/O SPI interface (DQ0–DQ3) with compatibility to standard SPI.
Key points:
- Capacity and addressing: 64 Mbit (8 MBytes) organized with 24‑bit addressing.
- Performance and operations: Fast Read up to ~104 MHz; Page Program up to 256 bytes; sector/block/chip erase; Write Enable/Disable; status and configuration registers with protection features.
- Power and modes: Low‑power options including Deep Power‑down and Release from Power‑down.
- Packaging and voltage: Available in 8‑pin packages; voltage ranges depend on variant (check datasheet for exact Vcc/temperature specs).
- Common uses: Boot firmware storage, code execution, and secure firmware updates in microcontroller-based designs.
For exact electrical specs, timing, and package options, consult the official datasheet.
