W25Q16JVWA

Winbond W25Q16JVWA is a 16-Mbit serial NOR flash memory.
- Capacity: 16 Mbit (2 MB) of non-volatile storage.
- Interface: SPI-compatible; standard SPI plus Dual/Quad I/O modes for higher throughput.
- Addressing/speed: 3-byte addressing; up to about 104 MHz in standard SPI (faster in Dual/Quad I/O modes).
- Voltage/temp: operates from 2.7–3.6 V; available in industrial temperature grade (-40°C to 85°C or similar).
- Organization and operations: 256-byte page programming; erase: 4 KB sectors, 32 KB/64 KB blocks; supports chip/sector/block erase and fast read; holds/power-down features.
- Security/protection: write-enable and block-protect registers; hardware write protection and deep power-down.
- Package: common 8-pin package (SOP8/US8) suitable for embedded boards.
- Applications: firmware storage and boot memory, code updates, data logging, and other embedded storage needs.
- Why choose: small footprint, single‑supply operation, good endurance, cost-effective non-volatile storage for microcontroller-based designs.
