The Motorola S-Record file format, often shortened to SREC or S19, is a text-based file format used to represent binary data, primarily for programming microcontrollers, EPROMs, and other embedded systems. It's a human-readable format, making it relatively easy to inspect and debug. Each line in an SREC file represents a record, starting with the character 'S' followed by a type code (S0, S1, S2, S3, S5, S7, S8, S9), a byte count, an address, the data bytes, and a checksum. The type code indicates the record's purpose: S0 for header information, S1/S2/S3 for data records with varying address sizes (16-bit, 24-bit, and 32-bit respectively), S5 for a count record (deprecated), and S7/S8/S9 for termination records with corresponding address sizes. The data bytes contain the actual binary data to be programmed into the target device. The checksum ensures data integrity during transmission or storage. SREC files are widely supported by various programming tools, compilers, and debuggers used in embedded systems development. The format's simplicity and widespread adoption have made it a standard for transferring binary data to embedded devices.
