2.1.1 Power Supply Pads on A8000 2 VBAT pads of A8000 connector are dedicated to connect the supply voltage, and 10 GND pads are recommended for grounding. VDD_LRTC used to back up RTC and VDD_LIO is a 2.85V LDO output for user application, max current 15mA, SWITCH_ON has the ON/OFF key function and RESET_N can reset system with logic low level. -
Page 8: Turn On / Off A8000
A8000 will enter SLEEP mode automatically after 5 seconds, which can shut down unnecessary functions of the A8000 module to minimizes the power consumption. In sleep mode, A8000 can still receive paging or SMS from network and the serial will not be accessible until A8000 be waked up. -
