3.3.2.4. VREG_MSME
3.3.2.4.1. Description
VREG_MSME is provided by an internal regulator of the NAD6200 module. VREG_MSME can be used to
source interface circuits like level shifters which are connected to the interfaces or GPIOs of the
NAD6200 module.
The current drawn on VREG_MSME shall not exceed 30 mA. When using VREG_MSME it is
recommended to decouple the signal with a combination of 1 µF and 22 pF directly at the board to
board connector.

3.3.2.5. SIM Card
3.3.2.5.1. Description
The SIM interface of the NAD6200 module is compatible to 1.8 V and 3 V SIM Cards. Necessary voltage
and level shifting is handled by NAD6200 module automatically. The SIM interface consists of the
following signals:
- VREG_USIM: SIM Supply Voltage
- USIM_CLK: SIM clock signal
- USIM_DATA: SIM data signal
- USIM_RESET: SIM reset signal
- GPIO69: SIM Present Signal
9
The data speed on the SIM interface is up to 4 Mbit. Hardware designer should take care of the length
and routing of the SIM interface to prevent potential problems.
