概要
Description
Introduction to W25X64VSFIG
- Type: Winbond 64-Mbit serial NOR flash memory (SPI interface), used to store firmware/data in embedded systems.
- Capacity: 64 Mbit (8 MB); memory organized for page/sector/block erase and program operations.
- Interface: Serial SPI (standard read, fast read modes available); supports common SPI signaling.
- Supply: Typically 2.7–3.6 V operation (industrial/commercial variants exist).
- Organization and operations: 256-byte pages; erase units include 4 KB sectors and larger blocks (32/64 KB); supports page program, sector/block/chip erase, Write Enable/Disable, and status/protection registers.
- Features: Non-volatile storage with fast random read/write access suitable for firmware storage; hardware write protection via status register.
- Applications: Storing microcontroller firmware, boot ROM, code/data storage in embedded systems.
- Package/variant: The suffix “VSFIG” identifies packaging, voltage range, and temperature grade; consult the datasheet for exact packaging and spec details.
