Tool/software:
Hi,
I was wondering if accessing a variable stored in FRAM (read or write) consumes more power than a variable in RAM. If not, are there any other drawbacks of FRAM compared to RAM? If there aren't any, what is the reason to still have RAM on MCU with FRAM? Access latency?
I am redesigning a product originally made by my colleague. He put most of the variables to RAM, but for the new design, we decided to put them in FRAM to preserve their state in case the chip loses power. Some of the variables get updated many times a second and I would like to make sure that having them in FRAM, combined with frequent access doesn't increase the device's power consumption (low power draw is a critical requirement).
