The 16 MHz clock is enough for sensor fusion loops, UART protocol handling, and real-time control tasks in industrial or battery-powered gear. ## I/O and connectivity for a 100-pin part The 16-channel, 12-bit ADC handles analog inputs from thermistors, potentiometers, or current shunts without an external converter.","metaTitle":"Texas Instruments MSP430FR68891IPZ 16-bit MCU, 128KB FRAM","metaDescription":"MSP430FR68891IPZ 16-bit MCU with 128KB FRAM, 16MHz CPU, 83 I/O, industrial temp -40°C to 85°C.
