Hi,
I am searching for a benchmark tool for benchmarking SRAM and FRAM read/write latency in MSP-EXP430FR6989, is there any suitable tools for me?
Thanks.

    There is no any latency in MSP430 SRAM, read or write will take 1 cpu cycle. For FRAM it depend on CPU MCLK, and on higer, there will be wait states. MSP430 flash is same as SRAM, without wait states. you can made simple benchmark with DMA copy (that will take min 2 cycles, 1 for read word, and another for store word).
