Non-volatile memory MC controllers
« on: August 30, 2023, 10:18:04 AM »
Hi,

Just a question, i think i haven't been paying attention :)
 
Have the MC0xx-1xx controllers all have FRAM memory since they were upgraded from MC0xx-0xx?

From the Technical manual BC152986484529en-000701:
"FRAM used in the MC0XX-1XX controller, is rated for 100 trillion read/write cycles per sector."

I always thought it was 1million cycles on the MC controllers...

Yep, it is as you say that all of the MC0xx-1xx controllers have the FRAM.  I'd still recommend using rising edge logic for writing to EE memory as a best practice.
