MSP430FR6877IPNR

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 with a smaller energy budget. FRAM technology combines the speed, flexibility, and durability of SRAM with the stability and reliability of flash memory at significantly lower power consumption. The MSP430 ULP FRAM product family consists of a variety of devices featuring FRAM, a ULP 16-bit MSP430 CPU, and intelligent peripherals, suitable for a wide range of applications. The ULP architecture has seven low-power modes, all of which are optimized to achieve long battery life in energy-constrained applications.
