A simple circuit to do it is:

GE863-PRO3Hardware User Guide

1vv0300773a Rev. 0 - 24/01/08

ON/OFF*-AP #

Q1

GND

NOTE: don't use any pull up resistor on the ON/OFF*-AP line, it is internally pulled up to VBATT2. Using

pull up resistor may bring to latch up problems on the GE863-PRO3power regulator and improper power on/off of the module. The line ON/OFF*-AP must be connected only in open collector configuration or tied to ground (if ARM needs to stay always on).

NOTE: In this document all the lines that are inverted, hence have active low signals are labeled with a name that ends with a "*" or with a bar over the name.

TIP: To check if the device has powered on, the hardware line 3.1V_OUT can be monitored.

It is possible to use also the SHDN line to turn ON the device with the ARM RTC trigger by connecting it to the ON/OFF*-AP pin through a transistor buffer.

After the Initial bootstrap, the line PC29 goes HIGH allowing the device to keep itself on;

If you need a toggle command to turn on/off the device, then you can use the line PC29 to keep the ARM on after it’s start-up and connect the on/off button to the ON/OFF*-AP pin through a buffer transistor while connecting it to a GPIO to sense it’s toggling (e.g. PC31) for shutting down the ARM by lowering the PC29 pin.

TIP: To Keep the ARM ON you can use the PC29 pin that goes high right after the bootstrap
