Interface Standard
PurposeTo provide this standard of specification for uniformity, multiplicity of sources, elimination ofconfusion, and ease of device specification and design by users.

1.2

Scope
This standard defines power supply voltage ranges, DC interface parameters for a family of
non-terminated digital circuits operating from a power supply of 1.5V and driving/driven by parts ofthe same family, or mixed families which comply with the input/output interface specifications.

Review of discussion historyJEDEC JC-16 (Low Voltage & High Speed Interface Sub-committee), called JEDEC after here,
which belongs to EIA (Electronic Industries Alliance) in U.S.A, enacted substantially the standard ofpower supply voltage for digital circuits in the world.
IC Low Voltage Operation Sub-committee which belongs to EIAJ (Electronic Industries Associationof Japan) has been cooperation with JEDEC and communicated mutually, since it was founded in1992.
A power supply voltage of digital circuits had been kept 5V, actually for a long time from 1980’s.
But, in 1990’s, a demand of low power supply voltage has become increasing to attain a low power
consumption and a high noise immunity of electric equipment, in a main application of portableequipment (note PC, etc) which need a long battery operation and high performance equipment (WS,etc) which require a high speed.
In 1990’s, also an age of deep sub-micron process technology (below 0.5mm process technology) hasbegun. Needs of low power supply voltage have become the most important issue to obtain a keepingof reliability and continuities of the trends of high density, high speed, together.
According to above back ground, discussion for standard of low power supply voltage, firstly 3.3V,
have begun in JEDEC, from early of 1990’s. 3.3V standard (JESD8-A) was enacted in June 1994,
2.5V standard (JESD8-5) was in October 1995 and 1.8V standard (JESD8-7) was in February 1997,
respectively.
EIAJ(IC Low Voltage Operation Sub-committee) began the discussion for standard of low power
supply voltage since April 1996, according to JEDEC's activities of power supply discussion, inanticipation of a real popularization of 3.3V power supply voltage from the half of 1990’s and comingof next lower supply voltage than 3.3V. EIAJ 3.3V standard (EIAJ ED-5001), 2.5V standard(EIAJ ED-5002) and 1.8V standard (EIAJ ED-5003) were enacted in May 1998, respectively.
These standards correspond to that of JEDEC about specifications, but these are amended from that ofJEDEC about notation and sentence for accomplishing unify of them among three JEDEC standards(3.3V, 2.5V, 1.8V).
Discussion of 1.5V standard has begun in JEDEC from September 1998, also EIAJ started at thesame time. EIAJ gave it’s comments to JEDEC draft, since December 1998. Especially, EIAJ carriedout the questionnaire about need of wide range and confirmed necessity of wide range from it’s

EIAJ ED-5004Aresults. JEDEC adopted EIAJ comment of wide range which wasn’t included in first draft.
EIAJ standard of 1.5V power supply voltage was established in June 2000.
This standard was composed of a normal range for regulated operation and a wide range for battery
operation, supposing an age of 0.15mm class IC.
After standardizing the dc standard, discussion on Schmitt trigger input standard was started by
JEITA / LVSC in February 2003. JEITA/LVSC submitted its proposed Schmitt trigger input standard
to JEDEC in March 2004, for the first time. JEDEC’s discussion on Schmitt trigger input standard was
begun by this proposal. The task-group was organized by JEITA / LVSC and JEDEC at the JEDECmeeting in June 2004. It has decided that the proposal of Schmitt trigger standard to be added intoexisting dc standard. Finally, the proposal of Schmitt trigger input standard was approved at theJEDEC meeting in December 2004. Based on the result of JEDEC meeting, JEITA’s revised
standard of 1.5V power supply voltage was revised as ED-5004A in May 2005.
