 On the [[:electronic:datasheet:sidebar|sidebar]] there is a list of component/device manufacturers, initially at least devices will be listed alphabetically by part number.  If my collection gets large then other categorization schemes may be implemented. On the [[:electronic:datasheet:sidebar|sidebar]] there is a list of component/device manufacturers, initially at least devices will be listed alphabetically by part number.  If my collection gets large then other categorization schemes may be implemented.

 +===== Date codes =====

 +
 +In the following “**n**” is a place holder for a digit, “**A**” for an alphabetic character, and “**X**” is either.
 +
 +“**nAn**” IC date codes\\
 +Many integrated circuits made in Asia used a three character code to state the year, month and week of manufacture.\\
 +Format //ymw//, so “6C4” means the 4th week of March 1986.
 +
 +^//m//^Month|
 +^A|January|
 +^B|February|
 +^C|March|
 +^D|April|
 +^E|May|
 +^F|June|
 +^G|July|
 +^H|August|
 +^J|September|
 +^K|October|
 +^L|November|
 +^M|December|
 +(NB "I" not used for month)
 +
 +
 +“**nnnn**” IC date codes\\
 +Many integrated circuits have a four digit code to state the week and year of manufacture.\\
 +Format //yyww// or //wwyy//, so “8610” or 1086 for tenth week of 1986.
 +
 +
 +
 +“**nnXX**” IC date codes\\
 +Many integrated circuits made by Sharp in the 1980s used a four character code to state the year, month and week of manufacture.\\
 +Format //nymw//: Id digit, Last digit of year, Month, Week.  So 921C means third week of January, 1982
 +^//m//^Month|
 +^1|January|
 +^2|February|
 +^3|March|
 +^4|April|
 +^5|May|
 +^6|June|
 +^7|July|
 +^8|August|
 +^9|September|
 +^X|October|
 +^Y|November|
 +^Z|December|
 +
 +^//w//^Week of month|
 +^A|Week 1|
 +^B|Week 2|
 +^C|Week 3|
 +^D|Week 4|
 +^E|Week 5|
