2. General Product Description
2.1. Overview
The aim of this document is the description of typical hardware solutions useful for developing a
product with the Telit CE910 module.
In this document all the basic functions of a mobile device will be taken into account; for each one of
them a proper hardware solution will be suggested and eventually the wrong solutions and common
errors to be avoided will be evidenced. Obviously this document cannot embrace all hardware
solutions and products that may be designed. Avoiding the discussed wrong solutions must be
considered as mandatory. While the suggested hardware configurations must not be considered
mandatory, the information given must be used as a guide and a starting point for properly developing
a product with the Telit CE910 module.
NOTE:
The integration of the CDMA 1xRTT module within a user application must be done according to the
design rules described in this manual.
The information presented in this document is believed to be accurate and reliable. However, no
responsibility is assumed by Telit Communication S.p.A. for its use, such as any infringement of
patents or other rights of third parties. No license is granted by implication or otherwise under any
patent rights of Telit Communication S.p.A. other than for circuitry embodied in Telit products. This

4. Hardware Commands
4.1. Turning on the CE910 module
To turn on the CE910, the pad ON_OFF* must be tied low for at least 1.5 second and then released.
The maximum current that can be drained from the ON_OFF* pad is 0.1 mA.
A simple circuit to power on the module is illustrated below:
4.1.1. Initialization and Activation State
Upon turning on CE910 module, the CE910 module is not active yet because the boot sequence of
CE910 is still executing internally. It takes about 10 seconds to complete the initialization of the
module internally.
For this reason, it would be useless to try to access CE910 during the Initialization state as below. The
CE910 module needs at least 10 seconds after the PWRMON goes High to become operational by
reaching the activation state.
