MSP430FR5870IRGCR

The MSP430FRxx FRAM microcontrollers in this ultra-low-power series come in a wide variety. Each member device is equipped with embedded non-volatile FRAM, a 16-bit CPU, and different peripheral sets to meet the needs of various applications. This architecture, combined with FRAM, peripherals, and seven low-power modes, is optimized specifically for extending battery life in portable wireless sensing applications. FRAM is a new type of non-volatile memory that perfectly combines the speed, flexibility, and durability of SRAM with the stability and reliability of flash memory, while consuming less overall power.
