MSP430FR5889IPM

The MSP430™ ultra-low-power (ULP) FRAM platform combines unique embedded FRAM with an overall ultra-low-power system architecture, enabling innovators to increase performance within a smaller energy budget. FRAM technology combines the speed, flexibility, and endurance of SRAM with the stability and reliability of Flash memory at significantly lower power consumption. The MSP430 ULP FRAM product family consists of multiple devices featuring FRAM, a ULP 16-bit MSP430 CPU, and intelligent peripherals, making it suitable for a wide range of applications. The ULP architecture offers seven low-power modes, all optimized to maximize battery life in energy-constrained applications.
