NOTES:
1. All inputs are tied to 0 V or VCC. Outputs do not source or sink any current.
The current consumption in LPM2, LPM3, and LPM4 are measured with active Basic Timer1 and LCD (ACLK selected).
The current consumption of the ESP430CE1B and the SVS module are specified in their respective sections.
LPMx currents measured with WDT+ disabled.
The currents are characterized with a KDS Daishinku DT38 (6 pF) crystal.
2. Current for brownout included.
current consumption of active mode versus system frequency
I(AM) = I(AM) [1 MHz] × f(System) [MHz]
current consumption of active mode versus supply voltage
I(AM) = I(AM) [3 V] + 170 A/V × (VCC – 3 V)
