Talk:Low Voltage Microcontrollers from MSP430

So at MSP430 day, they were a bit blindsided by this announcement. I knew more than they did, as a consequence of watching the ppt/voiceover. It's an exciting development, but I doubt that any project I'm involved with will ever hit ROM-like volumes, and the RAM-based development system is less exciting. MSP430 day DID talk about FRAM showing up in future msp430 products, and how it would be writable down to 1.5V (internal voltage, no charge pumps required for write, unlike flash.) So is there any chance that FRAM writable at 1.5V would be readable down to 0.9V and give us a reprogrammable "mid-volume production" solution for these very low voltage parts?

FRAM is certainly possible down to 0.9 volts. However, there is a speed issue. Above 1 Mhz, it may be necessary to add delay cycles when accessing FRAM. Also, since FRAM has a destructive read like old fashioned core, all read cycles are read/restore. Once the read is begun, there must be enough power available to complete the restore.
