64 KB FRAM — the non-volatile memory that writes like RAM
The MSP430FR5849IDAR: Its headline feature is 64 KB of FRAM program memory — a non-volatile storage technology that combines the fast write speed and low power of RAM with the data retention of Flash, without the erase-before-write penalty. This makes it a strong fit for applications that log data frequently, need field firmware updates, or operate on a tight energy budget where every write cycle costs microamps instead of milliamps.
