13、hnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To thi
14、s end and in addition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental org
15、anizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2)The formal decisions or agreements of the IEC on te
16、chnical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested National Committees. 3)The documents produced have the form of recommendations for international use and are published
17、in the form of standards, technical specifications, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent
18、 possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equip
19、ment declared to be in conformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. International Stand
20、ard IEC 60748-2-20 has been prepared by subcommittee 47A: Integrated circuits, of IEC technical committee 47: Semiconductor devices. This standard is a family specification for low voltage integrated circuits. The text of this standard is based on the following documents: FDISReport on voting 47A/59

23、 dimensions of integrated circuit devices are continuing to be reduced, both vertically and horizontally, to obtain better performance and higher density. However, if the supply voltages and interface levels are not reduced, the electric fields within the die (chip) will increase, which leads to red
24、uced reliability. These increased fields will also, together with the higher system-clock rates, lead to increased electromagnetic interference and noise induced on the supply leads and the ground plane, which leads to lower noise immunity and a higher probability of misoperation. To continue this t
25、rend of scaling down the size of semiconductor devices, lower power supply voltages are essential. For systems operating at lower supply voltages, the tolerances on the supply voltage and the input and output voltages must be specified more closely. Also, since the market for battery- operated equip
26、ment is expected to grow considerably, it is important to include specifications that cover this field. By setting standard values at this stage, manufacturing costs can be reduced and users can design systems more economically. BS IEC 60748220:2000 3 Licensed Copy: sheffieldun sheffieldun, na, Sun

28、 each comprises the nominal value of power supply voltage, its tolerances, and the worst-case limit values of the input and output voltages for low voltage integrated circuits. It also provides two categories of interface specification for each nominal supply voltage normal range and wide range. The
29、 normal range is based on the nominal industry standard with a typical tolerance of about 10%. The wide range covers battery operation which extends the lower limit to a practical value at which the battery will continue to operate. 2 Interface specifications for low supply voltages below 3,3 V 2.1
