attiny-wdt: Turn an ATtiny9 uC into a watchdog for another processor
|
|
|
|
|
====================================================================
|
|
|
|
|
|
|
|
|
|
The ATtiny9 is a small, ultra low cost microcontroller available in SOT-23
|
|
|
|
|
package. It is lower cost (and currently better available) than dedicated
|
|
|
|
|
hardware watchdog ICs.
|
|
|
|
|
|
|
|
|
|
So this project turns the ATtiny9 into a very simple "hardware watchdog IC"
|
|
|
|
|
for another processor/CPU.
|
|
|
|
|
|
|
|
|
|
The watchdog starts counting immediately from power-on and will trigger a reset
|
|
|
|
|
of the target system after 67s, unless the target system keeps refreshing the
|
|
|
|
|
watchdog via a low edge on another signal.

The device has been developed and tested, and has been deployed in production in
|
|
|
|
|
hundreds of systems.
