SIM Electrical Specifications
Each SIM card interface consist of a total of 12 pins (for 2 separate ports of 6 pins each. Mostly one port
with 5 pins is used).
The interface is meant to be used with synchronous SIM cards. This means that the SIM module provides
a clock for the SIM card to use. The frequency of this clock is normally 372 times the data rate on the
TX/RX pins, however SIM module can work with CLK equal to 16 times the data rate on TX/RX pins.
There is no timing relationship between the clock and the data. The clock that the SIM module provides
to the aim card will be used by the SIM card to recover the clock from the data much like a standard UART.
All six (or 5 in case bi directional TXRX is used) of the pins for each half of the SIM module are
asynchronous to each other.
There are no required timing relationships between the pads in normal mode, but there are some in two
specific cases: reset and power down sequences.

1
In low speed mode, card clock must be lower than 400 kHz, voltage ranges from 2.7 to 3.6 V.
2
In normal data transfer mode for SD/SDIO card, clock frequency can be any value between 0 ~ 25 MHz.
3
In normal data transfer mode for MMC card, clock frequency can be any value between 0 ~ 20 MHz.
4
In card identification mode, card clock must be l100 kHz ~ 400 kHz, voltage ranges from 2.7 to 3.6 V.
5
In identification mode, card output delay time should be less than 50 ns.
6
In data transfer mode, card output delay time should be less than 14 ns.
