Electrical Characteristics Introduction

The RPE-1 supply voltage must be in the range of 3.0 V to 5.25V. There is a special undervoltage sensing supervisor circuit for stopping the Card if VCC goes below the nominal 2.93V ( 2.92- 2.96V for the whole temperature range). If the voltage goes below this value, SimCardDetX is driven LOW and power-down sequence starts.
