GE863-QUAD

GE863-PY

1vv0300715 Rev. 1 - 19/09/06

9.4 SIM Supply

Do not connect capacitance greater than 10nF to SIMVCC line.

Other notes:

-SIMIN doesn't require any pull-up resistor. It is built in.

-SIM card is detected inserted when this line is short to ground.

-If in the application the SIM holder doesn’t foresee the switch for the presence/absence of the SIM card, the SIMIN line must be connected to ground.
