  • ※1R5104V: CTW=0.1µF, R5110S/ R51111S/R8360S: CTW=0.01µF
  • ※2Duration time=200ms
  • ※3The K class is guaranteed specification for full operating temperature range. The A class is guaranteed by design engineering at full operating temperature range. The R8360S is guaranteed specification for full operating temperature range.
  • ※4Window Watchdog Timer monitors the presence of output pulses from a CPU in a preset period of time (OPEN Window) , in case these pulses fail the watchdog timer will initiate a CPU reset after a time out period.
