L.R.A 78 Posted October 7, 2014 Anyone noticed that here: http://www.ti.com/lsds/ti/microcontrollers_16-bit_32-bit/msp/ultra-low_power/msp430g2x_i2x/overview.page Now where it was only MSP430G2x now it's MSP430G2x/i2x? Just curious, what is this? maybe a new MCU? Share this post Link to post Share on other sites
spirilis 1,263 Posted October 7, 2014 Saw that. I see it as a modern refresh of the MSP430AFExxx series. 24-bit Sigma Delta ADC designed around a +/-1.0V signal for measuring AC voltage & current for energy metering type of apps... but with the more modern eUSCI peripheral.

USWaterRockets 57 Posted October 18, 2014 Interesting new addition to the family. The fascinating bit is that it appears that they use multiple Sigma-Delta ADCs as apposed to a single ADC with a MUX on the input. According to the docs, there can be up to 8 ADCs on a single CPU and they can capture simultaneous readings. This is pretty serious analog, if it performs as advertised. 1 spirilis reacted to this Share this post Link to post Share on other sites
ILAMtitan 86 Posted October 20, 2014 Interesting new addition to the family.

According to the docs, there can be up to 8 ADCs on a single CPU and they can capture simultaneous readings. This is pretty serious analog, if it performs as advertised. It sure does perform as advertised. The new MSP430i20xx family is initially targeted for low cost embedded e-metering applications, and other industrial markets where high precision analog is a must. We already have a few TIDesigns posted regarding its usage: http://www.ti.com/tool/TIDM-SERVER-PWR-MON and http://www.ti.com/tool/TIDC-SMARTPLUG-WIFI In e-meter applications you must sample the voltage and current signals simultaneous, or else you will inject an artificial phase delay that has to be compensated in software. To accomplish this, all of our meteorology devices have multiple dedicated SD converters. Obviously you can use the high precision analog in other applications as well, but I'll leave that as an exercise for the reader. 1 spirilis reacted to this Share this post Link to post Share on other sites

spirilis 1,263 Posted November 5, 2014 Looks like the E2E MSP430 blog has an introductory post about it - http://e2e.ti.com/blogs_/b/msp430blog/archive/2014/11/05/a-new-feather-in-the-cap-new-msp430-industrial-series-microcontrollers-are-here.aspx For "Industrial" uses, hence the I. Good temperature tolerances as one might expect (-40 to 105C). Share this post Link to post Share on other sites
