MSP430FR6989 User Reference Manual Guide

●The MSP430FR6989IPZ is a 16-bit ultra-low-power Mixed-signal Microcontroller features an embedded FRAM non-volatile memory, powerful 16-bit RISC MSP430 CPU and different peripherals. The architecture showcases seven low-power modes, which are optimized to achieve extended battery life. FRAM is a new non-volatile memory that combines the speed, flexibility and endurance of SRAM with the stability and reliability of flash, all at lower total power consumption. The device configurations with five 16-bit timers, 12-bit A/D converter, liquid crystal display driver, a 16-channel comparator with voltage reference generation, a hardware multiplier and 83 general-purpose I/O pins. This device operates at a maximum frequency of 16MHz.
