BL24C02F 2Kb EEPROM for Whatsminer M30/M50 Hash Board Data Storage
The BL24C02F is a 2Kb serial EEPROM widely used on Whatsminer M30 and M50 hash boards for configuration storage, calibration data retention, and secure device parameter management. Its low-power architecture and high-speed I²C interface make it suitable for continuous operation in industrial mining environments.
Designed for reliable non-volatile memory storage, the BL24C02F supports 1MHz fast-mode operation, hardware write protection, and long data retention, enabling stable performance during hash board repair and refurbishment procedures.
Key Features
- 2Kb (256 × 8-bit) memory density
- I²C-compatible serial interface
- Supports fast-mode up to 1MHz
- Low power and wide voltage operation
- 16-byte page write buffer for efficient programming
- Hardware write protection for data integrity
- High endurance and long data retention
