6.6 Timing Requirements

At 1 V <VDD <6 V, SPT = LPT = Open, KILL = VDD,  CRESET = 50 pF, INT = 10K pull up to VDD and over the operating free-air temperature range of - 40°C to 125°C, unless otherwise noted. Typical values are at TA = 25°C.
Parameter Test Condition MIN TYP MAX UNIT
tSP Accuracy Short press duration accuracy  for fixed version(1) -10 10 %
Short press duration accuracy for adjutable version(1) SPT = 330pF, LPT = 4.7nF -20 20 %
tLP Accuracy Long press duration accuracy for fixed version -10 10 %
Long press duration accuracy for adjutable version SPT = 330pF, LPT = 4.7nF -20 -20 %
tSINT Accuracy Interrupt pulse width accuracy for PB long press  -10 10 %
tLINT Accuracy Interrupt pulse width accuracy for PB short press  -10 10 %
tKILL  Accuracy  PB/KILL debounce accuracy when RESET deaaserts in latched version -10 10 %
tRESET  Reset pulse duration (non latched) - Accuracy -10 10 %
tGI(KILL) Glitch Immunity at KILL pin 250 ns
tPD(KILL) KILL falling edge to RESET assert delay 500 ns
(1) tSPD should always be less than tLPD.
