5 Electrical specifications of the UICC - Terminal interface p. 27

5.0 General requirements p. 27

The electrical specification in the present document covers the supply voltage range from 4,5 V to 5,5 V, 2,7 V to 3,3 V, 1,62 V to 1,98 V and 1,1 V to 1,3 V. For each state (V_OH, V_IH, V_IL and V_OL), a positive current is defined as flowing out of the entity (terminal or UICC) in that state. Vpp shall be supported by terminals or UICCs that support the class A operating conditions only.

There are two states for the UICC while the power supply is on:

the UICC is in operating state when it executes a command from any of its interfaces. This state also includes transmission of the command from the terminal, executing the command and sending the response back to the terminal;
the UICC is in idle state at any other time. It shall retain all pertinent data during this state. In idle state, the clock may be stopped according to clause 6.6.

The clock duty cycle shall be between 40 % and 60 % of the period during stable operation. A clock cycle is defined at 50 % of Vcc from rising to rising edge or falling to falling edge. When switching clock frequencies terminals shall ensure that no pulse is shorter than 80 ns which is 40 % of the shortest allowed period.

When low impedance drivers are implemented on the I/O line, the I/O electrical circuit design shall insure that potential contention on the line will not result in any permanent damage of the terminal or the UICC. The terminal shall reduce the short circuit current on the I/O line by the means of a series resistor, the value shall be in the range of 47 Ω to 100 Ω.

5.1 Class A operating conditions p. 27

5.1.1 Supply voltage Vcc (contact C1) p. 27

The terminal shall operate the UICC within the following limits.

Table 5.1: Electrical characteristics of Vcc under normal operating conditions

Symbol	Minimum	Maximum	Unit
Vcc	4,5	5,5	V

The current consumption of the UICC shall not exceed the value specified in clauses 6.2.2 and 6.2.3 during the ATR (including activation and deactivation).

When the UICC is in idle state (see below) the current consumption of the card shall not exceed 200 μA at 1 MHz and 25 °C. If clock stop mode is enabled, then the current consumption shall also not exceed 200 μA while the clock is stopped.

The terminal shall source the maximum current requirements defined above. It shall also be able to counteract spikes in the current consumption of the card up to a maximum charge of 40 nAs and an amplitude of at most 200 mA, ensuring that the supply voltage stays in the specified range.

5.1.2 Reset (RST) (contact C2) p. 28

The terminal shall operate the UICC within the following limits.

5.1.3 Programming voltage Vpp (contact C6) p. 28

The UICC shall not require any programming voltage on Vpp. The terminal need not provide contact C6. If the terminal provides contact C6, then, in the case the terminal supports an ID-1 UICC under class A operating conditions only, the same voltage shall be supplied on Vpp as on Vcc, while in the case of Plug-in UICC/Mini-UICC/4FF the terminal need not provide any voltage on C6. Contact C6 may be connected to Vcc in any terminal supporting only class A operating conditions but shall not be connected to ground.

5.1.4 Clock CLK (contact C3) p. 28

The terminal shall support 1 MHz to 5 MHz. The terminal shall supply the clock. When only the interface specified in the present document is activated, no "internal clock" shall be used in the UICC.
