Intel HEX Format

Understanding the structure of Intel HEX encoded binary files

File Format Overview

Intel HEX is an ASCII text-based file format that represents binary data in hexadecimal encoding. Each line (record) starts with a colon ':' and contains hexadecimal characters encoding the record type, data length, memory address, payload data, and checksum.

Intel HEX Record Format
Intel HEX Record Structure

RECORD MARK

ASCII colon ':' character indicating the start of a record

RECLEN

Number of data bytes (0-255) in the record

LOAD OFFSET

16-bit starting load address for data records

RECTYP

Record type: 00=Data, 01=EOF, 02=Extended Segment, 03=Start Segment, 04=Extended Linear, 05=Start Linear

DATA

Payload containing the actual binary data in hexadecimal

CHKSUM

Two's complement checksum ensuring data integrity
