Description

W25Q256FVFIQ is Winbond’s 256-Mbit serial flash memory (W25Q family). It stores firmware/data and supports multiple SPI modes: standard (single), dual I/O, quad I/O, and QPI for high throughput.
Key points
- Capacity: 256 Mbit (32 MB)
- Interface: SPI with dual/quad I/O and QPI options
- Voltage: 3.3V (typ. 2.7–3.6V)
- Speed: up to 104 MHz read throughput (quad I/O/QPI modes available)
- Organization: 256-byte page program; 4 KB sectors; 64 KB blocks; full-chip erase
- Power: deep power-down mode; low-power operation
- Endurance/retention: typical erase/program cycles around 100k; long data retention
