For the ATmega32C1 the signature bytes are:
For the ATmega64C1 the signature bytes are:
The ATmega16/32/64/M1/C1 has a byte calibration value for the internal RC Oscillator. This
byte resides in the high byte of address 0x000 in the signature address space. During reset,
this byte is automatically written into the OSCCAL Register to ensure correct frequency of the
calibrated RC Oscillator.
This section describes how to parallel program and verify Flash Program memory, EEPROM
Data memory, Memory Lock bits, and Fuse bits in the ATmega16/32/64/M1/C1. Pulses are
assumed to be at least 250ns unless otherwise noted.
In this section, some pins of the ATmega16/32/64/M1/C1 are referenced by signal names
describing their functionality during parallel programming, see
Pins not described in the following table are referenced by pin names.
The XA1/XA0 pins determine the action executed when the XTAL1 pin is given a positive
pulse. The bit coding is shown in
When pulsing WR or OE, the command loaded determines the action executed. The different
Commands are shown in
1. 0x000: 0x1E (indicates manufactured by Atmel).
2. 0x001: 0x96 (indicates 64KB Flash memory).
3. 0x002: 0x84 (indicates ATmega64M1 device when 0x001 is 0x96).
1. 0x000: 0x1E (indicates manufactured by Atmel).
2. 0x001: 0x95 (indicates 32KB Flash memory).
3. 0x002: 0x86 (indicates ATmega32C1 device when 0x001 is 0x95).
1. 0x000: 0x1E (indicates manufactured by Atmel).
2. 0x001: 0x96 (indicates 32KB Flash memory).
3. 0x002: 0x86 (indicates ATmega64C1 device when 0x001 is 0x96).
