january 21st 2016 by admin microchip pic s up atmel microchip pic16c62 eng sample 1989 yesterday microchip makers of the pic line of microcontrollers announced they were buying atmel for a cool 3 56 billion this isn t entirely surprising considering the ongoing consolidation in the industry it was only last year that dialog attempted to purchase atmel and before that on semiconductor and microchip in december of 2015 nxp and freescale formerly motorola semiconductors merged creating one of the largest microelectronics companies these mergers do create an interesting result product mixes that were formerly competitors end up being marketed side by side in the case of nxp and freescale nxp marketed many mcs 51 microcontrollers in their 8 16 bit lines while freescale of course sold many versions of mc6800 based mcu s these two rivalries have existed since the early 1980 s and likely will continue perhaps the biggest rivalry in mcu though is between atmel and microchip atmel eprom fab d by gi in 1986 right before they became microchip microchip was spun off of general instrument in 1987 but the pic architecture dates back to 1976 and is still being made in nearly the same form pic16c55 atmel was started in 1984 first making eproms and then mcs 51 microcontrollers one of the very first companies to make an 8051 with on die flash memory in a bit of a twist of fate when atmel started it was a fabless company it contracted with several companies to make its eproms including sanyo and general instruments which as mentioned above became microchip atmel also makes aprc processors and for a time made motorola products as well atmel has a very convoluted history for more info on this read here and here today the pic line continues to be popular with devices for the low end such as the pic10 12 all the way to the mips based pic24 on the upper end atmel continues to make 8051 mcus but also makes the 8 and 32 bit avr line perhaps best known today for its use in arduino boards they also make mcu s based on the arm core a competitor to mips and atmel s own avr32 likely to the consternation to many fans of either company this merger does make sense more so than on or dialog buying atmel while microchip and atmel both compete in the same markets they do so with different architectures product lines are unlikely to change and overhead saving should free up both for stockholders yawn and engineering teams alike no word has been giving yet on wether microchip intends to keep the atmel branding but perhaps they should as an avr mcu with a microchip logo on it may just prove to be too much for some tags atmel mcs 51 microchip pic posted in processor manufacturers processor news april 9th 2015 by admin the e2v powerpc and hitce packages atmel pc7410mgh450le motorola marked package 2003 in the 1970 s second sources were quite important in the processor industry they provided a stable supply of a designed in part if the primary manufacturer which often only had a fab or 2 had problems they also could widen the market for the processor many of these agreements were kept active for decades after resulting in some interesting results motorola licensed many of their design to sgs which later merged with thomson to become stmicroelectronics though the thomson name was still used thomson license built most of motorola s product line as well as many high reliability versions in 1999 atmel bought thomson csf semiconductors and continued to make motorola products in their grenoble france fab which now included motorola s powerpc line as well as the 68k line of processors this portion of atmel was sold to e2v in england in 2006 which continued to produce the motorola now spun off as freescale powerpc line now branded as e2v the packaging used by e2v and previously atmel is the same as that used by motorola freescale the packages were custom made for motorola freescale by kyocera and others and so often chips with both atmel motorola and e2v freescale markings can be found it is this packaging that is of interest as it shows an interesting aspect of processor design read more tags atmel e2v hitce powerpc posted in

technology made obsolete in an incredibly short period of time by widely available and more flexible flash and eeprom technology processors evolved dram and sram evolved eproms simple ceased to exist there were attempts to make them faster lower power or in more convenient packages but at the end of the day or the end of the 90 s shining a uv light into a small round window to erase them simply became a sign of an era long passed that window however also allows for the beauty and in some cases massiveness of their silicon dies to be seen by all something today s black plastic flash simply cannot do here are a few of the interesting eproms i found in 2012 click to enlarge ami made many custom chips for clients as well as second sourced various designs this is a s5204a a copy of the national semiconductor mm5204 made in 1976 it stored 4kbits and had a fast access time of only 750ns it could be fully programmed in less then a minute and took only 10 minutes to erase all 4096 bits power draw was 750mw max about the same as a 800mhz intel atom processor the atmel at27c256r 55lc was a cmos 55ns 256kbit eprom in a surface mount package made in late 1996 it was the beginning of the end for eproms intel used some unusual packages for a few of their eproms this package was more commonly used on things like c8751s here it is a c27c202 70v05 engineering sample this is a 2mbit eprom no eprom collection is complete without at least a few examples of soviet eproms if anything for their amazing packages here a soviet of unknown plant k573rf5 made in 1989 this is a clone of the intel 2716 the soviet bloc mastered making eproms with plastic packages but this never caught on in the western market i have never seen a production eprom in a plastic package out side of east german ussr however i did acquire a plastic ti tmx2532 35nl tmx denotes it as a prototype the military and industrial markets continued to use eproms far longer then the commercial consumer markets cost being less of a concern then reliability eprom s had a proven track record and thus were used until flash had proven itself this is a waferscale integration wsi 27c256l 15 mil spec eprom tags atmel intel

because this is not the first time atmel has bought mhs in one form or another atmel matra mhs and temic s histories are rather intertwined with mergers acquisitions and name changes occurring frequently over the last 25 years a bit of history atmel 4mbit eprom 1995 atmel was founded in 1984 by george perlegos a former intel employee as a fab less semiconductor company originally atmel designed eprom s and plds they were manufactured by sanyo which had an intel license intel however sued atmel along with hyundai ict aas cypress and pacesetter electronics over eprom patents in 1987 the courts sided with intel which severely hampered atmel s ability to make eprom s their focus then switched to non volatile memories such as flash for which they have become very well known and continue to make in 1989 they bought their own fab from honeywell in colorado springs co and in 1993 released an 8051 intel licensed with integrated flash memory this catapulted atmel into the microcontroller market that is today one of their core businesses in 1994 atmel purchased seeq an eprom and eeprom company that perlegos helped start in 1981 in 1995 atmel opened a fab in rousset france thus beginning the french connection temic 80c32 1998 temic had its beginning in 1903 as telefunken ironically a joint venture of siemens and another company in 1967 aeg merged with telefunken and in 1985 daimler benz bought telefunken aeg and renamed it to simply aeg the semiconductor division of aeg was then called temic te lefunken mic roelectronics in 1998 aeg sold temic to vishay another automotive electronics supplier vishay only had interest in the discrete and power electronics portions so immediately sold the ic portion to atmel this gave atmel a bipolar fab in germany matra harris semiconductors sa mhs was created in 1979 as a joint venture between matra the french high technology group and harris semiconductor an american semiconductor manufacturer in 1989 harris withdrew from the partnership and the name was changed to matra mhs sa two years later aeg the electronics division of daimler benz purchased 50 of matra and merged the unit with its temic semiconductor subsidiary in 1998 aeg purchased the remaining shares of the company and the name was changed again to mhs sa mhs 80c52 1988 this was part of the sale to vishay mentioned above which atmel then purchased mhs had one cmos fab in nantes france which was included in the sale here is where it gets complicated the result of all of this was atmel now owned temic mhs 2 fabs in france one in germany their original fab in colorado as well as a fab in england and one in texas atmel needed to consolidate their fabs so in 2005 they sold the mhs fab in nantes france to xbybus a french company xbybus ran the nantes fab as mhs electronics in 2008 atmel sold their fab in germany the former temic fab to tejas semiconductor this left atmel with one fab in colorado and one in rousset france labor issues at the french fab in regards to atmel s need to reduce production led to indefinite strikes at this fab hampering atmel s work to sell it finally in 2010 atmel received approval from the french gov t to sell the fab to lfoundry a french company this marked the end of atmel s fab presence in france telefunken u3870m cpu mostek clone 1986 for about 9 months today atmel has bought mhs electronics and their fab in nantes france a fab they owned from 1998 2005 mhs had been having financial troubles since 2008 an interesting end to a series of event that began over 30 years ago i suspect though that we have not yet heard the last of mhs or perhaps temic tags atmel mhs telefunken temic posted in processor manufacturers research april 1st 2009 by admin atmel s new tiny avr a cpu that runs on a single aa battery most mobile electronics runs on around 3v for example your cell phone typically used a 3 7v li ion battery for some applications this much battery is not wanted or feasible a single aa battery produces 1 2 1 5volts but as it is used this voltage will drop atmel has just released a new line of their tiny avr risc microcontrollers that can run at voltages down to 0 7v internally they are a 3v design but they include a boost converter that can boost voltages from 0 7v to 1 8v to the 3v needed by the core as well as the 4k of flash and 64bytes of on board
