I didn't think that's enough to even advertise. 16KB is not even a usable text file.

Who said anything about text files? It's plenty for lots of 'embedded' applications. I used to program Motorola 68HC705K1's 504 bytes of eeprom/otprom and 32 bytes of ram.

You had 32 bytes? You were lucky! We used to dream of 32 bytes LOL

I agree -- 16KB might not sound much to some youngsters, but it goes a long way if you know what you are doing.

Seems like a good combination of features for the applications mentioned, sensors, home security, etc.  Is it missing anything you wish it had?

Given that most MCUs are (now) pushing MB use, I did find this quite light.

I actually have a MSP-EXP430FR5969 LaunchPad fraturing one of these little FRAM-based MCUs sitting on my desk -- I just need to find the time to play with it to discover more.

I'd be interested to hear from other readers as to how they would use the non-volatile nature of the FRAM to do things differently to the way they would use traditional Flash+SRAM MCUs

The claim of unlimited endurance is disingenuous. Please provide real measured or guaranteed cycles. MRAM has this same marketing habit as well.

Hang on -- 16KB is the max size for the old 57x MCUs -- the new 59x MCUs go upo to 64KB and the new 69x MCUs go up to 128KB

I think it has a shot at replacing SRAM but Flash is currently used for MB storage. MRAM is another candidate commonly proposed for the same purpose, because of its high (also not unlimited) endurance. Both can also be disturbed by cumulative if not direct reads. I wonder which would be the preference.

As I recall, the number they gave me was 10^15 = 1,000,000,000,000,000

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
