概述

Description

W25X64VSFIG is a Winbond 64M-bit serial flash memory (8 MB) that uses a standard SPI interface. It’s intended for firmware storage, code updates, and data logging in embedded systems.
Key points:
- Capacity: 64 Mbit (8 MB)
- Interface: SPI, with standard commands (READ, FAST READ, PAGE PROGRAM, SECTOR ERASE, BLOCK ERASE, CHIP ERASE, WREN, etc.)
- Organization: 256-byte page size; 4 KB sectors; 64 KB blocks
- Voltage: typically 2.7–3.6 V
- Speed: supports fast read modes up to high MHz ranges (consult datasheet for exact max)
- Features: write enable/disable, busy/status registers, deep power-down, hold, hardware write protection
- Endurance/retention: typical program/erase cycles in the 100k+ range; long data retention per datasheet
- Package: 8-pin (specific package variant indicated by the VSFIG suffix)
Use cases: firmware storage, boot devices, field updates, and small data logging. For exact timing, command set, and pinout, refer to the Winbond W25X64VSFIG datasheet.

Features

Winbond W25X64VSFIG features (concise):
- 64 Mbit (8 MB) serial flash memory
- SPI-compatible interface (standard SPI; supports fast/read modes)
- Page program size: 256 bytes
- Erase architecture: 4 KB sectors; 64 KB blocks; full-chip erase
- Erase/Program suspend and resume
- Ready/Busy (WIP) and Write Enable (WEL) status bits
- Deep power-down mode for low current
- Data retention around 20 years
- Endurance ~100,000 erase cycles per sector
- Operating voltage: typically 2.7–3.6V
- Temperature ranges: -40 to +85°C (commercial) or -40 to +125°C (industrial)
- Package: 8-pin SOIC/SOP (typical for W25X64 variants)
Applications: code/storage memory for microcontrollers, embedded systems, boot ROM, and data logging.

Package

8-pin SOP (SOIC-8) package.

Pinout
