Signature Bytes
All Atmel microcontrollers have a three-byte signature code which identifies the device. This
code can be read in both serial and High-voltage Programming mode, also when the device is
locked. The three bytes reside in a separate address space.
21.3.1
ATtiny25 Signature Bytes
1.
0x000: 0x1E (indicates manufactured by Atmel).
2.
0x001: 0x91 (indicates 2 KB Flash memory).
3.
0x002: 0x08 (indicates ATtiny25 device when 0x001 is 0x91).
21.3.2
ATtiny45 Signature Bytes
1.
0x000: 0x1E (indicates manufactured by Atmel).
2.
0x001: 0x92 (indicates 4 KB Flash memory).
3.
0x002: 0x06 (indicates ATtiny45 device when 0x001 is 0x92).
21.3.3
ATtiny85 Signature Bytes
1.
0x000: 0x1E (indicates manufactured by Atmel).
2.
0x001: 0x93 (indicates 8 KB Flash memory).
3.
0x002: 0x0B (indicates ATtiny85 device when 0x001 is 0x93).
21.4
Calibration Byte
Signature area of the ATtiny25/45/85 has one byte of calibration data for the internal RC Oscilla-
tor. This byte resides in the high byte of address 0x000. During reset, this byte is automatically
written into the OSCCAL Register to ensure correct frequency of the calibrated RC Oscillator.
