ATtiny24/44/84
Signature Bytes
Calibration Byte
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.
Signature bytes can also be read by the device firmware. See section
Signature Data from Software” on page
The three signature bytes reside in a separate address space called the device signature imprint
table. The signature data for ATtiny24/44/84 is given in
Table 19-7.
The device signature imprint table of ATtiny24/44/84 contains one byte of calibration data for the
internal oscillator, as shown in
written into the OSCCAL register to ensure correct frequency of the calibrated oscillator.
Calibration bytes can also be read by the device firmware. See section
Signature Data from Software” on page
