(GSM 11.11 version 6.2.0 Release 1997)16TS 100 977 V6.2.0 (1999-05)- The high current options of ISO/IEC 7816-3 [26] for V IH and V OH are not specified for the SIM as they apply toNMOS technology requirements. No realization of the SIM using NMOS is foreseen.5.1 Supply voltage Vcc (contact C1)The SIM shall be operated within the following limits:Table 1: Electrical characteristics of Vcc under normal operating conditionsSymbol Minimum Maximum UnitVcc 4,5 5,5 VIcc 10 mAThe current consumption of the SIM shall not exceed the value given in table 1 during any state (including activationand deactivation as defined in subclause 4.3.2).When the SIM is in idle state (see below) the current consumption of the card shall not exceed 200 µA at 1 MHz and25°C. If clock stop mode is allowed, then the current consumption shall also not exceed 200 µA while the clock isstopped.The ME shall source the maximum current requirements defined above. It shall also be able to counteract spikes in thecurrent consumption of the card up to a maximum charge of 40 nAs with no more than 400 ns duration and an amplitudeof at most 200 mA, ensuring that the supply voltage stays in the specified range.NOTE:A possible solution would be to place a capacitor (e.g. 100 nF, ceramic) as close as possible to thecontacting elements.5.2 Reset (RST) (contact C2)The ME shall operate the SIM within the following limits:Table 2: Electrical characteristics of RST under normal operating conditionsSymbol Conditions Minimum MaximumV OH I OHmax = +20 µA Vcc-0,7 Vcc (note)V OL I OLmax = -200 µA 0V (note) 0,6 Vt R t F C out = C in = 30 pF 400 µsNOTE:To allow for overshoot the voltage on RST shall remain between-0,3 V and Vcc+0,3 V during dynamic operation.5.3 Programming voltage Vpp (contact C6)SIMs shall not require any programming voltage on Vpp. The ME need not provide contact C6. If the ME providescontact C6, then, in the case of the ID-1 SIM the same voltage shall be supplied on Vpp as on Vcc, while in the case ofPlug-in SIMs the ME need not provide any voltage on C6. Contact C6 may be connected to Vcc in any ME but shall notbe connected to ground.5.4 Clock CLK (contact C3)The SIM shall support 1 to 5 MHz. The clock shall be supplied by the ME. No "internal clock" SIMs shall be used.If a frequency of 13/4 MHz is needed by the SIM to run the authentication procedure in the allotted time (seeGSM 03.20 [11]), or to process an ENVELOPE command used for SIM Data Download, bit 2 of byte 1 in the filecharacteristics shall be set to 1. Otherwise a minimum frequency of 13/8 MHz may be used.ETSI
(GSM 11.11 version 6.2.0 Release 1997)17TS 100 977 V6.2.0 (1999-05)The duty cycle shall be between 40 % and 60 % of the period during stable operation.The ME shall operate the SIM within the following limits:Table 3: Electrical characteristics of CLK under normal operating conditionsSymbol Conditions Minimum MaximumV OH I OHmax = +20 µA 0,7xVcc Vcc (note)V OL I OLmax = -200 µA 0 V (note) 0,5 Vt R t F C out = C in = 30 pF 9 % of period with a maximum of0,5 µsNOTE:To allow for overshoot the voltage on CLK shall remain between -0,3 V andVcc+0,3 V during dynamic operation.5.5 I/O (contact C7)Table 4 defines the electrical characteristics of the I/O (contact C7). The values given in the table have the effect ofdefining the values of the pull-up resistor in the ME and the impedances of the drivers and receivers in the ME and SIM.Table 4: Electrical characteristics of I/O under normal operating conditionsSymbol Conditions Minimum MaximumV IH I IHmax = ± 20 µA (note 2) 0,7xVcc Vcc+0,3 VV IL I ILmax = +1 mA -0,3 V 0,8 VV OH (note 1) I OHmax = + 20µA 3,8 V Vcc (note 3)V OL I OLmax = -1 mA 0 V (note 3) 0,4 Vt R t F C out = C in = 30 pF 1 µsNOTE 1: It is assumed that a pull-up resistor is used in the interface device (recommendedvalue: 20 kohms).NOTE 2: During static conditions (idle state) only the positive value can apply. Underdynamic operating conditions (transmission) short term voltage spikes on the I/Oline may cause a current reversal.NOTE 3: To allow for overshoot the voltage on I/O shall remain between -0,3 V andVcc+0,3 V during dynamic operation.5.6 StatesThere are two states for the SIM while the power supply is on:- The SIM is in operating state when it executes a command. This state also includes transmission from and to theME.- The SIM is in idle state at any other time. It shall retain all pertinent data during this state.The SIM may support a clock stop mode. The clock shall only be switched off subject to the conditions specified in thefile characteristics (see clause 9).Clock stop mode. An ME of Phase 2 or later shall wait at least 1 860 clock cycles after having received the lastcharacter, including the guard time (2 etu), of the response before it switches off the clock (if it is allowed to do so). Itshall wait at least 744 clock cycles before it sends the first command after having started the clock.To achieve phase compatibility, the following procedure shall be adhered to:A SIM of Phase 2 or later shall always send the status information "normal ending of the command" after the successfulinterpretation of the command SLEEP received from a Phase 1 ME. An ME of Phase 2 or later shall not send a SLEEPcommand.ETSI
