The status of the fuse bits is not affected by Chip Erase.
Note:
All Atmel microcontrollers have a three-byte signature code which identifies the device.
The three bytes reside in a separate address space.
For the ATtiny11 they are:
1. $000: $1E (indicates manufactured by Atmel)
2. $001: $90 (indicates 1 Kb Flash memory)
3. $002: $04 (indicates ATtiny11 device when signature byte $001 is $90)
For the ATtiny12
1. $000: $1E (indicates manufactured by Atmel)
2. $001: $90 (indicates 1 Kb Flash memory)
3. $002: $05 (indicates ATtiny12 device when signature byte $001 is $90)
Note:
The ATtiny12 has a one-byte calibration value for the internal RC oscillator. This byte
resides in the high byte of address $000 in the signature address space. During memory
programming, the external programmer must read this location and program its value
into a selected location in the normal Flash or EEPROM Program memory. At start-up,
the user software must read this Flash location and write the value to the OSCCAL
register.
Atmel’s ATtiny11 offers 1K bytes of Flash Program memory.
The ATtiny11 is shipped with the on-chip Flash Program memory array in the erased
state (i.e., contents = $FF) and ready to be programmed.
This device supports a High-voltage (12V) Serial programming mode. Only minor cur-
rents (<1 mA) are drawn from the +12V pin during programming.
The program memory array in the ATtiny11 is programmed byte-by-byte.
Atmel’s ATtiny12 offers 1K bytes of in-system reprogrammable Flash Program memory
and 64 bytes of in-system reprogrammable EEPROM Data memory.
The ATtiny12 is shipped with the on-chip Flash Program and EEPROM Data memory
arrays in the erased state (i.e., contents = $FF) and ready to be programmed.
This device supports a high-voltage (12V) serial programming mode and a low-voltage
serial programming mode. The +12V is used for programming enable only, and no cur-
rent of significance is drawn by this pin. The Low-voltage Serial Programming mode
CKSEL3..0 fuses: See Table 3, “Device Clocking Options Select,” on page 10 and
Table 10, “ATtiny12 Clock Options and Start-up Times,” on page 25, for which
combination of CKSEL3..0 to use. Default value is “0010”, internal RC oscillator with
long start-up time.
