(1) All inputs are tied to 0 V or to V_CC. Outputs do not source or sink any current.
(2) Not applicable for devices with HF crystal oscillator only.
(3) Characterized with a Micro Crystal MS1V-T1K crystal with a load capacitance of 12.5 pF. The internal and external load capacitance are
chosen to closely match the required 12.5 pF load.
(4) Low-power mode 2, crystal oscillator test conditions:
Current for watchdog timer clocked by ACLK and RTC clocked by XT1 included. Current for brownout and SVS included.
CPUOFF = 1, SCG0 = 0 SCG1 = 1, OSCOFF = 0 (LPM2),
f_XT1 = 32768 Hz, f_ACLK = f_XT1, f_MCLK = f_SMCLK = 0 MHz
(5) Characterized with a Seiko SSP-T7-FL (SMD) crystal with a load capacitance of 3.7 pF. The internal and external load capacitance are
chosen to closely match the required 3.7-pF load.
(6) Low-power mode 2, VLO test conditions:
Current for watchdog timer clocked by ACLK included. RTC disabled (RTCHOLD = 1). Current for brownout and SVS included.
CPUOFF = 1, SCG0 = 0 SCG1 = 1, OSCOFF = 0 (LPM2),
f_XT1 = 0 Hz, f_ACLK = f_VLO, f_MCLK = f_SMCLK = 0 MHz
(7) Low-power mode 3, 12-pF crystal including SVS test conditions:
Current for watchdog timer clocked by ACLK and RTC clocked by XT1 included. Current for brownout and SVS included (SVSHE = 1).
CPUOFF = 1, SCG0 = 1 SCG1 = 1, OSCOFF = 0 (LPM3),
f_XT1 = 32768 Hz, f_ACLK = f_XT1, f_MCLK = f_SMCLK = 0 MHz
Activating additional peripherals increases the current consumption due to active supply current contribution and due to additional idle
current. See the idle currents specified for the respective peripheral groups.
(8) Low-power mode 3, 3.7-pF crystal excluding SVS test conditions:
Current for watchdog timer clocked by ACLK and RTC clocked by XT1 included. Current for brownout included. SVS disabled (SVSHE =
0).
CPUOFF = 1, SCG0 = 1 SCG1 = 1, OSCOFF = 0 (LPM3),
f_XT1 = 32768 Hz, f_ACLK = f_XT1, f_MCLK = f_SMCLK = 0 MHz
Activating additional peripherals increases the current consumption due to active supply current contribution and due to additional idle
current. See the idle currents specified for the respective peripheral groups.
(9) Low-power mode 3, VLO excluding SVS test conditions:
Current for watchdog timer clocked by ACLK included. RTC disabled (RTCHOLD = 1). RAM disabled (RCCTL0 = 5A55h). Current for
brownout included. SVS disabled (SVSHE = 0).
CPUOFF = 1, SCG0 = 1 SCG1 = 1, OSCOFF = 0 (LPM3),
f_XT1 = 0 Hz, f_ACLK = f_VLO, f_MCLK = f_SMCLK = 0 MHz
Activating additional peripherals increases the current consumption due to active supply current contribution and due to additional idle
current. See the idle currents specified for the respective peripheral groups.
(10) Low-power mode 4 including SVS test conditions:
Current for brownout and SVS included (SVSHE = 1).
CPUOFF = 1, SCG0 = 1 SCG1 = 1, OSCOFF = 1 (LPM4),
f_XT1 = 0 Hz, f_ACLK = 0 Hz, f_MCLK = f_SMCLK = 0 MHz
Activating additional peripherals increases the current consumption due to active supply current contribution and due to additional idle
current. See the idle currents specified for the respective peripheral groups.
