1.3 Description

The MSP430™ ultra-low-power (ULP) FRAM platform combines uniquely embedded FRAM and a holistic

ultra-low-power system architecture, allowing innovators to increase performance at lowered energy

budgets. FRAM technology combines the speed, flexibility, and endurance of SRAM with the stability and

reliability of flash at much lower power.

The MSP430 ULP FRAM portfolio consists of a diverse set of devices featuring FRAM, the ULP 16-bit

MSP430 CPU, and intelligent peripherals targeted for various applications. The ULP architecture

showcases seven low-power modes, optimized to achieve extended battery life in energy-challenged

applications.
