17、BS EN ISO 60748-2-20:2008 3 INTRODUCTION The 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

18、die (chip) will increase, which leads to reduced reliability. These increased fields will also, together with the higher system-clock rate, 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 prob

19、ability of malfunction. To continue this trend of scaling down the size of semiconductor devices, lower power supply voltages are essential. For systems operating at lower supply voltage, the tolerances on the supply voltage and the input and output voltages must be specified more closely. Also, sin

20、ce the market for battery-operated equipment 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. After the publication of first

21、edition of this standard, scaling of digital ICs has still been drastically proceeding, and nowadays, state-of-the art digital ICs are operated at 1,2 V, and Schmitt trigger interface is widely used. In light of the situation, this second edition expands the specification of nominal power supply vol

22、tage down to 1,0 V and includes specifications of Schmitt trigger interface. BS EN ISO 60748-2-20:2008 4 SEMICONDUCTOR DEVICES INTEGRATED CIRCUITS Part 2-20: Digital integrated circuits Family specification Low voltage integrated circuits 1 Scope This standard aims at giving DC interface specificati

23、ons for various sets of values, where each comprises the nominal value of power supply voltage, its tolerance, 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 volt

24、age normal range and wide range. The normal range is based on the nominal industry standard with typical tolerance of about 10 %. The wide range covers battery operation that extends the lower limit to a practical value at which the battery will continue to operate. 2 Normative references The follow
