The 2 KB of SRAM handles stack and scratchpad data. This is the part for designs that want unified memory and field-update capability without wearing out Flash sectors.
The base product number MSP430FR68221 covers the family; the I suffix indicates the industrial temperature grade, G the 56-TSSOP package, and R the tape-and-reel shipping medium.
The base product number is MSP430FR68221; the I, G, and R suffixes specify temperature grade, package, and packaging. Any variant with the same base number and compatible suffix codes is a direct functional replacement. Check the suffix table in the datasheet to confirm pin compatibility.
The CPU core runs at 16 MHz maximum. That is the instruction cycle rate for the MSP430 CPUXV2.
