• Clock CLK (contact C3)
The Terminal shall support 1 to 5 MHz. The Terminal shall supply the clock. No "internal
clock" UICC shall be used.
The duty cycle shall be between 40 % and 60 % of the period during stable operation.
The Terminal shall operate the UICC within the following limits:

NOTE: To allow for overshoot the voltage on CLK should remain between -0,3V and Vcc+0,3V
during dynamic operations.

• I/O (contact C7)
Table 14 defines the electrical characteristics of the I/O (contact C7). The values given in the
table allow the derivation of the values of the pull-up resistor in the Terminal and the
impedance of the drivers and receivers in the Terminal and UICC.

NOTE 1: It is assumed that a pull-up resistor is used on the interface device (recommended value:
20 k
Ω ).
NOTE 2: During static conditions (idle state) only the positive value can apply. Under dynamic
operating conditions (transmissions) short term voltage spikes on the I/O line may cause
a current reversal.
NOTE 3: To allow for overshoot the voltage on I/O shall remain between -0,3V and Vcc+0,3V
during dynamic operation.
