Signature Bytes
Calibration Byte
2467V–AVR–02/11
the EESAVE fuse which will take effect once it is programmed. The fuses are also latched on
power-up in normal mode.
All Atmel microcontrollers have a three-byte signature code which identifies the device. This
code can be read in both serial and parallel mode, also when the device is locked. The three
bytes reside in a separate address space.
For theAtmel
1. $000: $1E (indicates manufactured by Atmel)
2. $001: $97 (indicates 128Kbyte Flash memory)
3. $002: $02 (indicates ATmega128 device when $001 is $97)
The ATmega128 stores four different calibration values for the internal RC Oscillator. These
bytes resides in the signature row high byte of the addresses 0x000, 0x0001, 0x0002, and
0x0003 for 1MHz, 2MHz, 4MHz, and 8MHz respectively. During Reset, the 1MHz value is auto-
matically loaded into the OSCCAL Register. If other frequencies are used, the calibration value
has to be loaded manually, see “Oscillator Calibration Register – OSCCAL” on page 41 for
details.
