JWoodrell 285 Posted March 23, 2013 Share Posted March 23, 2013 Nothing i can see in the datasheet indicates tolerance above 3.6V Quote Link to post Share on other sites
cde 334 Posted March 23, 2013 Author Share Posted March 23, 2013 2x55 (7/8/9) Side by Side with 2452 and 2553 datasheets show: 2 Timer_A and 1 Timer_B High Freq Crystal Clock Mode External Resister Clock Mode 0.2 Quote Link to post Share on other sites
L.R.A 78 Posted March 23, 2013 Share Posted March 23, 2013 PDIP 40 (Available in Sample Quantities!!!! I wonder what the procedure is, as it's not a standard package for this family) (two DVCC and DVSS to pad the chip pin count to 40 I didn't see any PDIP40 on 2744, 2544 nor 2344.

cde 334 Posted March 23, 2013 Author Share Posted March 23, 2013 I didn't see any PDIP40 on 2744, 2544 nor 2344. See the datasheet. As I said, it's non-standard packaging, and only available in sample quantities, as per the datasheet. Quote Link to post Share on other sites
L.R.A 78 Posted March 23, 2013 Share Posted March 23, 2013 your right. i only tried to see in the samples. It isn't there Quote Link to post Share on other sites
spirilis 1,265 Posted March 23, 2013 Share Posted March 23, 2013 So my F5172 LaunchPad will have one legitimate use--5V tolerance (In addition to portmapper, Timer_D) Sent from my C3PO via Tapatalk Quote Link to post Share on other sites
RobG 1,892 Posted March 24, 2013 Share Posted March 24, 2013 Amazing, there's a PDIP 40 package pinout drawing, I wonder if they will do 2955's in PDIP. Quote Link to post Share on other sites
oPossum 1,083 Posted March 24, 2013 Share Posted March 24, 2013 PDIP 40 is fracking huge. Would like to see any of those chips in skinny DIP 28 or even 20. Quote Link to post Share on other sites
RobG 1,892 Posted March 24, 2013 Share Posted March 24, 2013 I agree, DIP 28 should be more than enough ( and I already have a bunch of DIP 28 sockets left over from all the TLC5940 stuff I did ) Quote Link to post Share on other sites
cde 334 Posted March 24, 2013 Author Share Posted March 24, 2013 I can't check, since I'm on my phone, but wouldn't all the important pins fit on a 28 tssop layout? Sure the last 5 on each side won't be connected, but that's what mgnet wire is for. Quote Link to post Share on other sites
cde 334 Posted March 24, 2013 Author Share Posted March 24, 2013 Yea, looked at the pinout. You'd lose all of port 4, but you'd also lose AVcc and AVss. The datasheet has no information on if or how or when those should be connected, or what it is used for (aside from the adc, natch). Unlike Atmel, which has a section on the analog voltage pins. But two thin magnet wires to tie those pins to dvcc and dvss. Quote Link to post Share on other sites
L.R.A 78 Posted March 24, 2013 Share Posted March 24, 2013 is MSP430FR5739 tolerant to 5v inputs as long i give 5V to AVCC? and can it be programed with msp430g launchpad? Quote Link to post Share on other sites
jim940 28 Posted March 26, 2013 Share Posted March 26, 2013 Interesting....seems like they're gunning for the Arduino chips indeed But this also means they have to increase the flash limits of the free version of CCS right? Does anyone know the code efficiency (flash size) taken of MSP430 vs. AtMega328 code? The base bootloader on the Arduino is at least 2Kb. Still, 16kB is good for many projects, plus we always have GCC if we need to use something else. But maybe TI will keep seeing the light and make it a 32kB code limit for CCS at the minimum at least for the Value Line chips. Jim Quote Link to post Share on other sites

Jim Assuming they did a launchpad( or any other type of dev board for that matter ) for these new chips, they could very easily board lock CCS for unlimited use. Like with the Stellaris launchpad.

paulpthcom 19 Posted March 26, 2013 Share Posted March 26, 2013 Just a heads up, received the MSP-FET430U38 kit today. Haven't had a chance to do anything other than open it up, but at least mine only included the 2274, not the 2744 or 2955 listed. Is missing the Microcrystal too. Not a huge issue but thought it was worth noting. Quote Link to post Share on other sites
