Présentation
Description
The EFM25F128A is a 128Mb (16MB) serial NOR flash memory from Winbond, part of their W25Q series. It features:
- SPI interface (supports Standard, Dual, Quad, and QPI modes)
- High-speed performance: Up to 104MHz clock frequency
- Low power consumption: Ideal for embedded systems
- Flexible erase/program options: Sector (4KB), block (32/64KB), and full-chip erase
- Wide voltage range: 2.7V–3.6V operation
- Hardware/software write protection
Commonly used in IoT, automotive, consumer electronics, and firmware storage, it offers reliable, non-volatile storage with fast read/write speeds.
For detailed specs, refer to the Winbond datasheet.
