ILPM4 -- LPM4 Current vs Temperature 5.5 Schmitt-Trigger Inputs – Ports P1 to P6, RST/NMI, JTAG (TCK, TMS, TDI/TCLK,TDO/TDI) over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted) PARAMETER TEST CONDITIONS MIN MAX UNIT VIT+ Positive-going input threshold voltage VCC = 2.2 V 1.1 1.55 V VCC = 3 V 1.5 1.98 VIT– Negative-going input threshold voltage VCC = 2.2 V 0.4 0.9 V VCC = 3 V 0.9 1.3 Vhys Input voltage hysteresis (VIT+ – VIT– ) VCC = 2.2 V 0.3 1.1 V VCC = 3 V 0.5 1 (1) The external signal sets the interrupt flag every time the minimum t(int) parameters are met. It may be set even with trigger signals shorter than t(int). 5.6 Inputs Px.y, TAx over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted) PARAMETER TEST CONDITIONS VCC MIN MAX UNIT t(int) External interrupt timing Port P1, P2: P1.x to P2.x, external trigger signal for the interrupt flag(1) 2.2 V 62 ns 3 V 50 t(cap) Timer_A capture timing TA0, TA1, TA2 2.2 V 62 ns 3 V 50 f(TAext) Timer_A clock frequency externally applied to pin TACLK, INCLK t(H) = t(L) 2.2 V 8 MHz f(TBext) 3 V 10 f(TAint) Timer A clock frequency SMCLK or ACLK signal selected 2.2 V 8 MHz f(TBint) 3 V 10 (1) The leakage current is measured with VSS or VCC applied to the corresponding pins, unless otherwise noted. (2) The port pin must be selected as input. 5.7 Leakage Current – Ports P1 to P6 over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted) (1) PARAMETER TEST CONDITIONS MIN MAX UNIT Ilkg(Px.y) Leakage current, Port Px V(Px.y) (2) VCC = 2.2 V, 3 V ±50 nA |
