What's different with MSP430G2513IPW20 ver A & ver C

Hi Grace,

You can always find the differences between revisions listed in the device errata document. This document is linked from the product page www.ti.com/.../msp430g2513 right under the link to the datasheet there is a link to the errata document (copied here):
www.ti.com/.../slaz438 Looking at the errata document, you can see that there should be no difference between Rev. A and Rev. C.

Could you please give more information about what issue you are seeing with the new devices - what specifically is failing? What could be happening could be normal device-to-device variation within the datasheet spec - sometimes I see people have applications that have something that depends on a particular spec being a bit tighter than what is guaranteed in the datasheet, so then when they get a different lot of parts they may have an issue simply due to normal device variation.

Another really good test would be to take one of your working units with Rev. A on it, and one of your new failing units with Rev. C on it, and swapping the parts (put the Rev. C part on the good board and the Rev. A part on the bad board). After this test both boards - did the issue follow the board or the device? This can help tell you if the dependency is on the silicon, or if it could be an issue with the PCB or soldering or something on the latest batch of boards from your board manufacturer. Another test would be, if these parts are failing functionally and were both already programmed, would be to read out the code as well to make sure that it has the same code version between the passing and failing parts.

Regards,
Katie
