All specification are at an ambient temperature of 25°C.
Average current drawn during Continuous Tracking Mode with 1 Hz update rate, using 9 channels for tracking and navigation and 3
Peak current drawn during initial acquisition phase. Use this figure to dimension maximum current capability of power supply.
RxD1, RxD2 and EXTINT0 provide internal pull-up to V_BAT18 (Battery supply regulated to 1.8V) and not VCC.
Do not drive high.
