JWoodrell 285 Posted March 26, 2013 Share Posted March 26, 2013 I got a target board in as well that should have had the 2955 in today (MSP-TS430DA38) as well, and it has only the 2274 chips in it, although mine has the microcrystal. I'm talking to digikey to see if their other kit in stock has them or not Quote Link to post Share on other sites

RobG 1,892 Posted March 26, 2013 Share Posted March 26, 2013 Yes. Now I can create Eagle part for it today and swap with F5132 in my current project. Quote Link to post Share on other sites

spirilis 1,265 Posted March 26, 2013 Share Posted March 26, 2013 So they are releasing PDIP-40 versions then. The TI news article mentions the MSP430 LaunchPad Expansion board, available in May -- https://www.olimex.com/Products/MSP430/Booster/MSP430-G2744BP/?DCMP=mspvalue-g2xx&HQS=mspvalue-g2xx-olimex-pr-lp (guess they partnered with Olimex for that one). It stuffs a PDIP-40 up top and breaks it out into 40-pin XL sized headers. edit: G2744 at least. The "PDIP available in sampling quantities" thing. Guess that's a one-off run for their Olimex expansion board. izdane, RobG and bluehash 3 Quote Link to post Share on other sites
on3pk 4 Posted March 26, 2013 Share Posted March 26, 2013 Is it wrong to want a PDIP 40 just for the sake of having it? Quote Link to post Share on other sites
cde 334 Posted March 26, 2013 Author Share Posted March 26, 2013 Just got an email too: The data sheet links are the same as on the g2744 and g2955 pages. Both of those are available for sampling now. With the video being: http://focus.ti.com/general/docs/video/Portal.tsp?entryid=0_sa3dsbvp&DCMP=mspvalue-g2xx&HQS=mspvalue-g2xx-em-v&sp_rid_pod4=OTE2NTUwNzY3MQS2&sp_mid_pod4=41219500 The video also mentions the DIP 40 Pin package. spirilis 1 Quote Link to post Share on other sites
simpleavr 399 Posted March 26, 2013 Share Posted March 26, 2013 Is it wrong to want a PDIP 40 just for the sake of having it? i wish they have some 28pin narrow dip devices / packaging. a 40 pin dip won't fit in tiny breadboards. RobG 1 Quote Link to post Share on other sites
on3pk 4 Posted March 26, 2013 Share Posted March 26, 2013 i wish they have some 28pin narrow dip devices / packaging. a 40 pin dip won't fit in tiny breadboards. I think you need a Texas sized breadboard for this Texas sized unit. ;-) GG430 and RobG 2 Quote Link to post Share on other sites
spirilis 1,265 Posted March 27, 2013 Share Posted March 27, 2013 An obvious benefit of these, which I hadn't even thought of until on3pk's discussion about data-flash ("EEPROM") writing, is the practicality of reserving larger segments of this main program flash for data write-back. How does writing to program flash generally work if done from program code in the flash? Looking at the x2xx user's guide it seems like it's functional except during any flash erase or write operations the program can't really run, it just spins in place, but I guess writing a data-designated section of the program flash is doable. With 4KB SRAM there's plenty of scratch to temporarily store the 512-byte segments of main program flash for when you need to "update" stored data already in place.

paulpthcom 19 Posted March 27, 2013 Share Posted March 27, 2013 Is there any difference between the MSP430G2744 and MSP430F2744? The details look pretty much identical except that the G part has a higher current listed in Standby mode for some reason. roadrunner84 1 Quote Link to post Share on other sites
pabigot 355 Posted March 27, 2013 Share Posted March 27, 2013 There is no MSP430F2744. There's an MSP430F2274, which is identical to the MSP430G2744 in terms of memory and peripherals except it has on-board opamps. The internal architecture of the value-line series would change power profiles, chip errata, and possibly the accuracy of calibration constants. llc[12]$ egrep 'Name|2..4' /msp430/msp430mcu/upstream/devices.csv # Device Name,CPU_TYPE,CPU_Bugs,MPY_TYPE,SBW,EEM,BREAKPOINTS,CLOCKCONTROL,CYCLECOUNTER,STACKSIZE,RAMStart,RAMEnd,RAMStart2,RAMEnd2,USBRAMStart,USBRAMEnd,MirrowedRAMSource,MirrowedRAMStart,MirrowRAMEnd,BSLStart,BSLSize,BSLEnd,INFOStart,INFOSize,INFOEnd,INFOA,INFOB,INFOC,INFOD,FStart,FEnd,FStart2,FEnd2,Signature_Start,Signature_Size,INTStart,INTEnd msp430f2234,0,0,0,1,EMEX_LOW,2,STANDARD,0,80,0200,03FF,0,0,0,0,0,0,0,0,0,0,1000,40,10FF,10C0,1080,1040,1000,E000,FFDD,0,0,,,FFE0,FFFF msp430f2254,0,0,0,1,EMEX_LOW,2,STANDARD,0,80,0200,03FF,0,0,0,0,0,0,0,0,0,0,1000,40,10FF,10C0,1080,1040,1000,C000,FFDD,0,0,,,FFE0,FFFF msp430f2274,0,0,0,1,EMEX_LOW,2,STANDARD,0,80,0200,05FF,0,0,0,0,0,0,0,0,0,0,1000,40,10FF,10C0,1080,1040,1000,8000,FFDD,0,0,,,FFE0,FFFF msp430g2444,0,0,0,1,EMEX_LOW,2,STANDARD,0,80,0200,03FF,0,0,0,0,0,0,0,0,0,0,1000,40,10FF,10C0,1080,1040,1000,E000,FFDD,0,0,,,FFE0,FFFF msp430g2544,0,0,0,1,EMEX_LOW,2,STANDARD,0,80,0200,03FF,0,0,0,0,0,0,0,0,0,0,1000,40,10FF,10C0,1080,1040,1000,C000,FFDD,0,0,,,FFE0,FFFF msp430g2744,0,0,0,1,EMEX_LOW,2,STANDARD,0,80,0200,05FF,0,0,0,0,0,0,0,0,0,0,1000,40,10FF,10C0,1080,1040,1000,8000,FFDD,0,0,,,FFE0,FFFF llc[13]$ diff -u /msp430/msp430mcu/analysis/peripherals/msp430{g274,f227}4.periph --- /msp430/msp430mcu/analysis/peripherals/msp430g2744.periph 2013-03-25 13:32:48.522471649 -0500 +++ /msp430/msp430mcu/analysis/peripherals/msp430f2274.periph 2013-03-25 13:32:47.541478264 -0500 ADC10 BC2 FLASH2 +OA_2 PORT1_R PORT2_R PORT3_R paulpthcom 1 Quote Link to post Share on other sites
RobG 1,892 Posted March 27, 2013 Share Posted March 27, 2013 Wait, does this mean TI took near-end-of-life MCU, changed one letter in the name, lowered the price, and market it as new? ike 1 Quote Link to post Share on other sites
