// S-Record - Motorola's hex format for embedded systems and microcontrollers
Industry Standard
Motorola's official format for programming microcontrollers and embedded systems.
Address Sizes
Support for 16-bit (S1), 24-bit (S2), and 32-bit (S3) addressing.
Checksum Protection
Each record includes checksum for error detection and data integrity.

How S-Record Works:
S-Record format represents binary data as ASCII hex records. Each line starts with 'S' followed by type, byte count, address, data, and checksum. Different record types support various address widths.
Record Types:
S0: Header record S1: Data (16-bit address) S2: Data (24-bit address) S3: Data (32-bit address) S5: Count record S7/S8/S9: Termination
Why Use S-Record:
- >Motorola MCU programming
- >Embedded firmware
- >PROM programmers
- >Cross-platform transfer
- >Debug and verification
>> frequently asked questions
What is S-Record format?
S-Record (SREC) is Motorola's hex file format for conveying binary information as ASCII text. It's widely used for programming microcontrollers and transferring data to embedded systems.
What's the difference between S1, S2, and S3 records?
The main difference is address width: S1 uses 16-bit addresses (up to 64KB), S2 uses 24-bit addresses (up to 16MB), and S3 uses 32-bit addresses (up to 4GB). Choose based on your memory requirements.
How does the checksum work?
The checksum is the one's complement of the sum of all bytes in the record (count, address, and data). It ensures data hasn't been corrupted during transmission or storage.
S-Record vs Intel HEX?
Both are similar text-based formats. S-Record is from Motorola, Intel HEX from Intel. S-Record supports larger addresses natively and has more record types, while Intel HEX is more common in some tools.
