概要
Description
The W25Q256FVEIQ is Winbond’s 256-Mbit serial flash memory (W25Q family) designed for firmware storage and data logging in embedded systems. It uses a serial SPI interface with Quad I/O options for higher throughput.
Key points:
- Capacity and addressing: 256 Mbit (32 MB); supports standard SPI commands with 4-byte addressing for full memory access.
- Interface and speed: SPI-compatible; Quad I/O/Quad Output modes available for faster data transfer.
- Organization: 256-byte pages; 4 KB sectors; 64 KB and 256 KB blocks.
- Endurance and retention: non-volatile memory with typical flash endurance and long data retention.
- Features: JEDEC ID, status registers, hardware/ software write protection, deep power-down mode.
- Reliability and variants: available in industrial-grade versions; suitable for boot flash and firmware storage.
- Package: commonly 8-pin SOIC/WDF type.
Note: exact electrical specs (voltage range, timing, endurance) vary by variant; consult the Winbond datasheet for detailed parameters and supported commands.
