7.6 SIGROW - Signature Row
The content of the Signature Row fuses (SIGROW) is pre-programmed and read-only. SIGROW contains information such as device ID, serial number, and calibration values.
All the AVR64DA28/32/48/64 devices have a three-byte device ID that identifies the device. The device ID can be read using the Unified Program and Debug Interface (UPDI), also when a device is locked. The device ID for the AVR64DA28/32/48/64 devices consists of three signature bytes, which is given by the following table.
Device Name | Signature Byte Address and Value | ||
---|---|---|---|
0x00 | 0x01 | 0x02 | |
AVR64DA64 | 0x1E | 0x96 | 0x12 |
AVR64DA48 | 0x1E | 0x96 | 0x13 |
AVR64DA32 | 0x1E | 0x96 | 0x14 |
AVR64DA28 | 0x1E | 0x96 | 0x15 |
