Talk:List of common microcontrollers

message: We need a good summary comparison of the DIY programmable microcontrollers -- the ones such as BASIC Stamp, PICAXE, and Arduino that can be developed for no more than about $100 (if you already have a general-purpose computer to host the development).  It should list the power supply voltage range, the minimum power consumption, the max clock speed, the min cost for a development system (quan. one), the min cost for a target system (quan. one), the programming languages, and whether a complete open-source development set is available (no proprietary assembler-compilers etc).  And the range of RAM and EEPROM available.

thread_title:  summary comparison 

message: Should the SigmaTel (now Freescale) SOC's be covered here? STMP35xx, STMP36xx, etc.
 I couldn't seem to find them in the list, but I might have missed them.  Zodon (talk) 09:43, 9 July 2008 (UTC)
thread_title:  SigmaTel/Freescale 

message: My background is 1.) I like to tear apart embedded stuff from DOCSYS modems to Linksys WRT54 to phones to Car Computers (yes they can be reprogrammed for better performance via JTAG or serial port for older ones, against the Law per EPA), DVD players and Set top boxes and Printer, et al. and 2.) I worked at Phillips and John Fluke Manufacturing which made test interfaces: in-circuit emulators (ICE), Meters, Oscilloscopes, etc.).
This section should be for embedded microcontrollers found when you take apart a DVD player or Refrigerator logic board, for example. Classic definition is CPU, RAM, ROM/PROM (that is NOT "user" programmable), RAM, Clock?, self-contained I/O to control surroundings. 
Chips NOT enumerated here but have been extensively used as microcontrollers are: 
* Fairchild 3870 (also made by Mostek)(everything from video games to vending machines), similar programming model to CP1650/Microchip
* TI TMS-1000 series (calculators, home appliances, cars), introduced 1972.
* The original Rockwell PPS-4, was introduced in the third quarter of 1972. 
* TI TMS 9940, based on TMS9900 which was based on TI 990 Minicomputer. 
* GI PIC1650 (not very popular but became the Microchip forerunner), also PIC1670, PIC1645, PIC1655.
* Synertek "6502" series (Rockwell, Harris Semiconductors, Conexant Systems, their CPU handbook said they were second source) e.g. R6501 with RAM/IO but Ext ROM),
* RCA CDP1804 (also Intersil and Harris Semiconductor), the 1802 was the go to processor for Military and Space missions due to radiation resistance.
* Intel 8020/8022 microcontrollers
* HD6301 CMOS, used in Epson HX-20, my portable thermal printer (Brother 600), Fluke Meters, etc.
* AMD ELAN series
Less used but still were prevalent in some sectors:
* TI TMS7000 series (short lived?, 8-bit)
* National Semiconductor NSC807x (NSC8073 had Basic interpreter in ROM, predated Z8 8671-Basic and i8052-Basic chips)
* General Instrument PIC1650 I/O processor (minor part of the CP1600 MCU peripheral chipset) for all the simple people who like Microchip. The Wiki Microchip article revises  history. My information is from Adam Osborne's (a person of note who lived in that era) "An Introduction to Microprocessors". General Instruments 16xx MCUs were common in Set Top Boxes and External Modems among other uses (G.I. only supported volume users).
Re: microcontroller definition as self contained embedded system. The original IBM Super VGA was an add on "8514A" card containing TMS32020 DSP(controller)(had "host interface". IBM 8514 video accellerator commands sent to the card were adopted as VESA command set, and these Video Controllers diverged to TIGA(TMS32040 to TMS32096) and S3 types. I have one system with Chip and Technologies CT69030 with internal ROM and 2 MB RAM on chip, basically a dedicated microcontroller with a host interface. ATI Mobility is similar. Newer video products allow user retasking e.g. dedicating video stream processors to join a Linux cluster.

message: Cyberbot II has detected that page contains external links that have either been globally or locally blacklisted.
Links tend to be blacklisted because they have a history of being spammed, or are highly innappropriate for Wikipedia.
This, however, doesn't necessarily mean it's spam, or not a good link.
If the link is a good link, you may wish to request whitelisting by going to the request page for whitelisting.
If you feel the link being caught by the blacklist is a false positive, or no longer needed on the blacklist, you may request the regex be removed or altered at the blacklist request page.
If the link is blacklisted globally and you feel the above applies you may request to whitelist it using the before mentioned request page, or request it's removal, or alteration, at the request page on meta.
When requesting whitelisting, be sure to supply the link to be whitelisted and wrap the link in nowiki tags.
The whitelisting process can take its time so once a request has been filled out, you may set the invisible parameter on the tag to true.
Please be aware that the bot will replace removed tags, and will remove misplaced tags regularly.

replies: text: One of the worst of the worst parts of Wikipedia.  Long after cypress.com got banned, I asked for Cypress to be taken off the list, but the answer was no.  One person alluded that I might be a cypress employee just for asking, which I consider slander since I've never worked for any IC manufacturer / IC distributor / IC sales group.  At some point, I might try to ask again, though it will likely be a waste of my time.  • Sbmeirow • Talk • 15:56, 23 June 2014 (UTC)

thread_title:  External links modified 

message: The current information is not exact:
* PIC10 and PIC12: 12-bit instruction words
* PIC16 series: 14-bit instruction words, one address pointer ("indirect register pair")
The real model name to architecture correspondence is more complicated:
* PIC10F2xx, PIC12F5xx, PIC16F5xx: “baseline” architecture — 12-bit instruction words
* PIC10F3xx, PIC12Fxxx, PIC16Fxxx (except PIC12F5xx, PIC16F5xx): “mid-range” architecture — 14-bit instruction words, one address pointer (“indirect register pair”)
* PIC12F1xxx, PIC16F1xxx: “enhanced mid-range” architecture — 14-bit instruction words, two address pointers (“indirect register pair”) [also: many additional instructions, automatic context-saving on interrupts, and some other enhancements].
There may be “LF” instead of “F” in most of the type names for the corresponding low-voltage version; few models have “HV” abbreviation instead of “F” for a high-voltage version, and the old EPROM devices have “C” instead of “F”.  — Preceding unsigned comment added by Mnashe (talk • contribs) 13:32, 24 October 2019 (UTC)
