Slight digression, but the MSP430 is obsolete; modern low power ARM microcontrollers are superior in every dimension.[1]
[1] I have worked on products with both uC, and the company where I work buys both by the reel and tray.
- david-given 10y agoWould those be the new Atmel SAM L21? I see a reference to 35 µA/MHz and 200 nA sleep mode: http://www.atmel.com/products/microcontrollers/arm/sam-l.aspx http://www.atmel.com/products/microcontrollers/arm/sam-l.asp... So: (a) yay! super low power processors! Bet you can run these off a couple of long wires and radio scavanging; (b) ARMs are so dull. [sad face] The MSP430 is a lovely processor to write machine code for. ARMs are just... dull. Anyway, thanks for the suggestion. I think the MSP430s have a monopoly on FRAM, which makes a vast difference in usability, but I'll check these out.
