SIST ETS 300 641 E1:2003 is the Slovene adoption of ETS 300 641, a European Telecommunication Standard for the GSM Phase 2 Subscriber Identity Module - Mobile Equipment (SIM - ME) interface. It specifies the electrical and logical requirements for 3 Volt (3V) technology in the Mobile Station (MS), especially where 3V operation differs from GSM 11.11. In practice, it is the document for designers and testers who need a SIM and mobile equipment to recognise, power, and switch between 3V and 5V SIM operation.
What does SIST ETS 300 641 E1:2003 specify?
SIST ETS 300 641 E1:2003 specifies the 3V parts of the SIM - ME interface used in a GSM Mobile Station (MS). Where the standard does not add 3V-specific rules, GSM 11.11 (ETS 300 608) applies.
The document is organized into:
- Scope
- Normative references
- Definitions, abbreviations and symbols
- 3V technology
- Electrical specifications of the SIM - ME interface
- Annex A, which is informative and covers cross compatibility aspects
Annex A is a compatibility matrix rather than a requirements annex. It helps readers see how different SIM and ME technology combinations behave at start-up.
What are the key requirements of SIST ETS 300 641 E1:2003?
SIST ETS 300 641 E1:2003 sets out how a 3V SIM and a 3V-capable ME must start up, identify each other, and operate electrically. The main practical point is that equipment may need to begin at 5V, detect whether the SIM supports 3V, and then switch safely if needed.
SIM operation and compatibility
Clause 4.1 states that a 3V technology SIM shall work at both 5V and 3V. It also requires clock stop mode support and the "Clock Stop Allowed" indication in the file characteristics. For users, this means the card must remain usable in mixed GSM fleets and in power-saving modes.
Clause 4.8 explains cross compatibility: an ME may support both 3V and 5V, but that is optional for the ME. A 3V technology SIM is intended to give full cross compatibility, which matters when cards are used across different handset generations.
Identification and start-up behaviour
Clause 4.3 requires a 3V technology SIM to carry an identification bit in the status information. The ME has to read this immediately after ATR, using SELECT GSM and STATUS/GET RESPONSE, before issuing any other command. In practice, this is the decision point for whether the ME can stay at 5V or move to 3V.
Clause 4.4 says a 3V technology ME shall initially activate the SIM at 5V and may switch to 3V if the SIM identifies itself as 3V-capable. Clause 4.5 gives the opposite case for a 3V only ME: it activates at 3V and must reject a 5V only SIM, or a SIM that cannot complete identification, without continuing the session.
Activation, voltage switching and electrical limits
Clause 4.6 requires activation and deactivation to follow GSM 11.11, while respecting the electrical characteristics in this standard. Clause 4.7 adds a key rule for dual-voltage equipment: voltage switching shall be done only by deactivating the SIM and then reactivating it at the new voltage.
Clause 5 gives the electrical specification for 3V operation. It covers supply voltage, clocking, signal levels, current consumption, pulse timing, and the treatment of contact C6 (Vpp). For engineering work, this is the section used to design the interface and to verify that the ME can supply the card and signal lines correctly under load.
What terms does SIST ETS 300 641 E1:2003 define?
- 3V technology SIM - A SIM that operates at 3V ± 10% and 5V ± 10%.
- 3V technology ME - An ME that supports the SIM - ME interface at 3V under this standard and at 5V under GSM 11.11.
- 3V only ME - An ME that operates the SIM - ME interface only at 3V.
- ATR (Answer To Reset) - The SIM response used by the ME as the starting point for identification and control.
- SIM (Subscriber Identity Module) - The removable module that holds subscriber identity and related data.
- ME (Mobile Equipment) - The terminal that hosts the SIM and controls the SIM - ME interface.
- Vcc - The SIM supply voltage used by the interface.
Who uses SIST ETS 300 641 E1:2003?
SIST ETS 300 641 E1:2003 is used by mobile equipment designers, SIM suppliers, test laboratories, and GSM compliance teams. It matters to engineers who must implement 3V start-up, switching, and signal timing, and to quality managers who need to verify that cards and terminals interoperate safely. Buyers and integrators use it to check whether a product supports 3V SIMs, dual-voltage operation, or only 3V operation.
What changed in SIST ETS 300 641 E1:2003 from the previous edition?
SIST ETS 300 641 E1:2003 is identified as identical to ETS 300 641 Edition 1. The ETS itself states that it corresponds to GSM technical specification GSM 11.12 version 4.1.2.
Which standards are used with SIST ETS 300 641 E1:2003?
The normative reference is:
- GSM 11.11 (ETS 300 608) - It provides the base SIM - ME interface rules, including the 5V operation and the logical procedures that this ETS builds on.
This standard says that for any aspect of the SIM - ME interface not covered here, GSM 11.11 applies.
What does the SIST ETS 300 641 E1:2003 document contain?
Clause 4 contains the operational rules for 3V technology, including SIM identification, start-up behaviour, voltage switching, and cross compatibility. Clause 5 contains the electrical characteristics for the interface and includes Tables 1 to 5 for I/O, CLK, RST, and Vcc behaviour under normal operating conditions.
Annex A is informative and gives a compatibility matrix for different SIM and ME technology combinations. It is useful when checking how a design behaves with 5V only, 3V, dual-voltage, and future low-voltage cases.
The front matter also records the ETSI origin, transposition dates, and the relationship to GSM 11.12.
