ATtiny13 Rev. A
ATtiny13
debugWIRE communication not blocked by lock-bits
Watchdog Timer Interrupt disabled
EEPROM can not be written below 1.9 Volt
Problem fix/ Workaround
Avoid the above fuse combinations. Selecting longer start-up time will eliminate the problem.
When debugWIRE on-chip debug is enabled (DWEN = 0), the contents of program memory
and EEPROM data memory can be read even if the lock-bits are set to block further reading
of the device.
Problem fix/ Workaround
Do not ship products with on-chip debug of the tiny13 enabled.
If the watchdog timer interrupt flag is not cleared before a new timeout occurs, the watchdog
will be disabled, and the interrupt flag will automatically be cleared. This is only applicable in
interrupt only mode. If the Watchdog is configured to reset the device in the watchdog time-
out following an interrupt, the device works correctly.
Problem fix / Workaround
Make sure there is enough time to always service the first timeout event before a new
watchdog timeout occurs. This is done by selecting a long enough time-out period.
Writing the EEPROM at V
Problem Fix/Workaround
Do not write the EEPROM when V
Revision A has not been sampled.
– 4.8 MHz internal oscillator (CKSEL[1..0] = 01), shortest start-up time
(SUT[1..0] = 00), Debugwire enabled (DWEN = 0) or Reset disabled RSTDISBL = 0.
CC
below 1.9 volts might fail.
CC
is below 1.9 volts.
