About This Tool

The EEPROM extractor analyzes raw binary dumps from I2C or SPI EEPROM devices to identify stored strings, configuration data, version identifiers, and memory patterns. It supports common device types and maps addresses to a logical memory layout. The tool is intended for firmware engineers, hardware analysts, and security researchers who work with embedded systems. It provides a clear extraction pipeline and structured outputs to support validation and reverse engineering.
Conceptually, the memory is treated as a sequence of bytes with addressing rules applied to decode strings and numeric fields. It focuses on readability, traceability, and repeatable results across multiple images. The core value is a fast, automated way to recover configuration data, firmware identifiers, and readable content from dumps without manual hex hunting.
Unique differentiators include broad device-type detection, endianness-aware decoding, and structured exports (CSV/JSON) that preserve address context. Typical use cases include recovering configuration parameters, embedded strings, version identifiers, and CRC-blocks within EEPROM dumps. It benefits engineers performing binary analysis, testers validating memory contents, and researchers mapping data structures in firmware.

How to Use

  1. Provide inputs: upload the EEPROM binary image; select device_type (I2C 24xx or SPI 25xx); set address_start and address_end; choose endianness and encoding.
  2. Run extraction: execute the process to parse the defined memory window and decode data.
  3. Review outputs: inspect extracted_strings, numeric_values, and address_map for context.
  4. Export results: save to CSV or JSON for documentation or testing.
  5. Validate findings: compare recovered strings and numbers against known firmware patterns.

Frequently Asked Questions

Find Quick Answers

What EEPROM types are supported?
Supports I2C 24xx and SPI 25xx families, with 8- or 16-bit addressing and various endianness options. Device detection and explicit type selection help disambiguate data interpretation.
Can I export results?
Yes; results can be exported as CSV or JSON, preserving address context, strings, and numeric fields for reporting and tooling pipelines.
What inputs are required?
You must provide a raw binary EEPROM image, specify device_type, and set address_start and address_end. Optional inputs include encoding and endianness to tailor decoding.
