Integration Guide
Version 1.01
Figure 11 shows a typical connection from an external processor to the GSM0108 module, using the external
PWR_CTL_SIGNAL solution. The GSM0108 can be powered on by using the PWR_CTL_SIGNAL signal. When
using PWR_CTL_SIGNAL, the I/O or serial lines can be at any voltage state desired. It is suggested that the I/O
and serial lines be tri-stated or set low when the GSM0108 is shutdown for an extended period of time to conserve
power.
