MSP430 that uses FRAM – Remembers forever (Virtually)

As well as shout about the products we want to make, I want to make this blog about other cool tech that we see/use. With that in mind, FRAM (Ferroelectric RAM) has come across my desk this week. FRAM has the speed of RAM but is non-volatile so won’t forget what it knows when it looses power. The mainstream alternative Flash is traditionally used for such jobs but doesn’t yet have the speed of RAM, just about every Microcontroller on the market uses Flash of some sort. Well that was until recently when TI announced they were adding FRAM to their MSP430 range. The MSP430 range has some of the lowest powered micro’s in the industry with the additional of FRAM, that can go even lower, instead of hibernating the processor with just enough power to keep the SRAM alive it can just switch off. The FRAM retains the processors state and varibles, power up again and carry on where it left off.  Even if you’re not that interested in the low power side the other advantages of FRAM, it’s speed and maximum write cycles make it a very exciting technology.  TI do a cheap developers kit, much like the launchpad
