#95082 - FRAM Life Responding to: ???'s previous message |
I'd not noticed the 3v/5v life difference. I must have read an app note relating to 3v devices when I considered life was now effectively infinite. We have used FRAMs (on 5v) for 10 years now - previously a XICOR e-squared device.
We also read several locations EVERY 20ms (initially in ignorance of the life limit - RAMTRON don't exactly make a big issue of it). This is industrial control equipment, so is on permanently. That's a theoretical 10G reads in ~6 years. Not had a failure yet (although, one wonders if power down volatility might be a failure symptom, and ours, as I said, never switch off). On reflection, 6 years is just about a nice product lifetime ;-) I HAVE sorted the 20ms read 'problem' on our later kit, however. Dave |
