Lgbeno 189 Posted June 7, 2015 Share Posted June 7, 2015 So I often find myself asking this question: I use the original launchpad almost exclusively with MSP440G2553. I know that there are lower cost, more capable parts out there but every time I go back to the old reliable G2553. Do others on the forum find this to be true for them as well? Theres just something about the part that is so familiar and comfortable. Honestly I think that it is the user guide. I was trying to use timer in AVR recently and was going through the docs and thought I could have already had this done with G2553! Also one other random rant: If it wasn't for Arduino 5V circuits would have been dead 5 years ago! Sent from my iPhone using Tapatalk Quote Link to post Share on other sites
enl 227 Posted June 7, 2015 Share Posted June 7, 2015 I use it as a go to for similar reasons. The price is good, dev tools are decent, peripherals well designed, still pretty close to lowest power consumption for what it can do. Quote Link to post Share on other sites
RobG 1,892 Posted June 7, 2015 Share Posted June 7, 2015 Same here. I pretty much implement all my new ideas or test code on 2553, because it takes me only few minutes to do so. The problem with 2553 is availability and price. $2.00-$2.80 is way too much and I hear that every time I am trying to convince someone to use 2553. With increased RAM (1K or 2K) and lower price ($1.00,) 2553IN20 could become the MCU of choice for many hobbyists, educators, and many others. Quote Link to post Share on other sites
Lgbeno 189 Posted June 7, 2015 Author Share Posted June 7, 2015 Good points, i do also wish price was lower. Newark does a decent just with discounts but still 1.50 for g2553 is quite high (i still pay it) The problem is that if TI was to offer the part priced super low in low volume then it would screw up their medium volume pricing. There should be a hobby distributor with a Max order quantity for TI to fuel hobbyists. Sent from my iPhone using Tapatalk Quote Link to post Share on other sites
RobG 1,892 Posted June 7, 2015 Share Posted June 7, 2015 Well, they could also lower their medium volume pricing. Besides, who would buy and use IN20 in large quantities (except distributors?) Quote Link to post Share on other sites
Lgbeno 189 Posted June 7, 2015 Author Share Posted June 7, 2015 Yeah that would be a welcome change, by "medium" I mean like 1000 pcs or more. It would be interesting to know if a single production product is using DIP! I'm not a DIP guy myself, I usually use 32QFN. Sent from my iPhone using Tapatalk Quote Link to post Share on other sites
veryalive 49 Posted June 7, 2015 Share Posted June 7, 2015 2553 is great! I often downsize to other favorites for which I have small stock on hand: 2252, 2452. Quote Link to post Share on other sites
enl 227 Posted June 7, 2015 Share Posted June 7, 2015 I will freely admit that I am still a DIP guy. Several reasons: I'v been around a long time so familiarity is a piece; I can see a DIP without the microscope; Most of what I do anymore is personal or for teaching, and being able to pop a 2553 or 2452 or.. into breadboard with a small cap an a resistor and nothing else, rather than make up a PC board, is a big benefit.

spirilis 1,265 Posted June 7, 2015 Share Posted June 7, 2015 I'm all about TI's TSSOP packages myself. Compact yet manageable pin pitch. Sent from my Galaxy Note II using Tapatalk Quote Link to post Share on other sites
username 198 Posted June 8, 2015 Share Posted June 8, 2015 For hobby use with low pin counts, yes, always G2553. For commercial use or if more pins are needed, I go with freescale MCUs or whatever i'm forced to use. Yes, I likewise hate the arduino 5V... 3.3V is fine for me in every application even in low power. RROMANO001 1 Quote Link to post Share on other sites
RROMANO001 6 Posted June 28, 2015 Share Posted June 28, 2015 I am using it many way: Teaching it can fit on breadboard just with reset resistor and power capacitor. Prototype to test hardware or software before have board. Development and production on small package 32QFN I learned how to solder on board to test first board before preproduction. TSSOP or SSOP on small production of less than 100 board when some hand solder are needed instead of loading pick and place. Quote Link to post Share on other sites
Rei Vilo 695 Posted June 28, 2015 Share Posted June 28, 2015 I really like the DIP-20 package as it is easy to solder by hand. I use it for smart sensors as I Quote Link to post Share on other sites
yyrkoon 250 Posted July 19, 2015 Share Posted July 19, 2015 When I think of the need for a small limited use MCU, the g2553 is always on my mind too. Not sure what the prices are now days, but we got / could get a tube of 20 for $1.25 each. Not bad considering what this little badboy can do, and how little power it uses. Thing I like about the chip is for me( and probably many others ), it's a known quantity. Passed that, I really like the fact that I can write code / compile / upload binaries using nothing but OSS( using the launchpad of course ). Which nowdays, makes me all warm and fuzzy inside Also having familiarity with the MCU definitely does not hurt. Quote Link to post Share on other sites
enl 227 Posted July 19, 2015 Share Posted July 19, 2015 Since this thread is resurrected, might as well mention what I did on my summer vacation: 2452 was the processor of choice, as I had a few around. Someone with more money that reason was the client. A roughly 100 yr old power plant D'arsonval movement was the victim. A DS18B20 was the imperitus. Money in my pocket was the result. Eventually (when I finish the setup in my own house, since I got paid to do the work and marginal cost for me is scrap bin plus a little time) I will post. Not original concept, but ideal for the 2452. Quote Link to post Share on other sites
cde 334 Posted July 19, 2015 Share Posted July 19, 2015 Frankly the reason 5V circuits are still around is that USB is the defacto power standard. If there was a 5V MSP430 part, I'd use that for everything. Quote Link to post Share on other sites
