New (soon to be) valueline chip. MSP430G2955 56kb Flash 4kb Ram!

Recommended Posts

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

  • 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.

See the datasheet. As I said, it's non-standard packaging, and only available in sample quantities, as per the datasheet.

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.

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.

Interesting....seems like they're gunning for the Arduino chips indeed :smile:

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.

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.

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.
