Visão Geral
Description
Key points:
- Capacity: 512 Mbit (64 MB).
- Interface: SPI-compatible serial interface; supports standard SPI and higher-throughput dual/quad I/O modes; includes 3-byte and 4-byte addressing.
- Operations: supports typical NAND flash commands such as page-program, block-erase, fast/random read, and status/protection features.
- Voltage and packaging: operates from 2.7–3.6 V; “FIQ” indicates a specific package type/temperature range.
- Applications: boot devices, firmware storage, data logging, and other embedded storage tasks.
Note: For exact command set, timing, endurance, protection options, and pinout, refer to the W25M512JV product datasheet and the documentation for the specific FIQ package variant.
