Mot file

Motorola S-Record (SREC) is a file format commonly used to represent binary data in a human-readable ASCII text format. It was originally developed by Motorola for their line of microcontrollers and has since become a widely adopted standard for exchanging binary data between devices in a human-readable form.

Record structure

Each record in the file begins with an 'S' character followed by a record type identifier (S0 through S9), specifying its purpose. An S-record can store actual data, vendor specific information and information about the starting address or the number of records.

The structure consists of fields such as record length, memory address, data in hexadecimal format, and a checksum for data integrity. SREC files are generated by development tools, and their human-readable format facilitates debugging and manual editing, while the checksums ensure the accuracy of the transferred data during programming.

Application

The SREC file format frequently finds application in programming memory devices like microcontrollers, EEPROMs, and flash memory. It is used to transfer machine code or firmware updates from a development environment, such as a compiler or assembler, to the target device.
