BL24C02F 2Kb I²C EEPROM for Whatsminer M30 / M50 Hashboard
The BL24C02F is a 2Kb serial EEPROM widely used on Whatsminer M30 and M50 hashboards for configuration storage, calibration data retention, and secure device parameter management. 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 1 MHz fast-mode operation, hardware write protection, and long data retention — enabling stable performance during hashboard repair and refurbishment procedures.
Key Features
- 2Kb (256 × 8-bit) memory density.
- I²C-compatible serial interface.
- Fast-mode up to 1 MHz.
- Low power + wide voltage operation.
- 16-byte page write buffer for efficient programming.
- Hardware write protection for data integrity.
- High endurance + long data retention.
Typical Use in M30 / M50 Hashboard Repair
- Configuration EEPROM replacement — restoring failed config storage on hashboard.
- Calibration data restoration — re-programming after EEPROM failure.
- Hashboard refurbishment — bulk EEPROM inventory for production lines.

FAQ — BL24C02F EEPROM
Q: Pre-programmed?
A: No — new chips ship blank. Use a K9 / K8 tester or compatible programmer to write the hashboard's calibration data after installation.
Q: 24C02 family — interchangeable?
A: Pin-compatible with standard 24C02 variants (AT24C02, 24LC02, etc.). For OEM-spec repair, stick with BL24C02F.
Q: Bulk pricing?
A: Yes — email contact@lys-sz.com.
