Low-Power FRAM Microcontrollers and Their Applications
Texas Instruments recently announced a new microcontroller family that implements FRAM as non-volatile memory instead of Flash, today's most common programmable, non-volatile memory technology. The paper explains the FRAM technology and how embedded applications can benefit from it. The physics behind the FRAM technology are briefly covered. The differences and benefits of FRAM versus other non-volatile memory technologies like Flash are shown like the low current consumption, the fast write, and the high write endurance. The concept of "universal memory" is also introduced. This paper illustrates how embedded applications can benefit from the features the FRAM technology offers such as ultra-low power data loggers and batteryless energy harvesting applications.
