MSP430FR69891IPZR

MSP430FR69891IPZR is a Texas Instruments MSP430 ultra‑low‑power microcontroller in the FR6989 family. It uses a 16‑bit MSP430 core and FRAM (nonvolatile) memory, offering fast, high‑endurance writes and near‑instant wake‑ups with very low power. Peripherals typically include multiple 16‑bit timers, a 12‑bit ADC, analog comparators, a DMA engine, and serial communications (USCI) for UART, SPI, and I2C, plus an LCD controller for low‑power displays. It supports a wide supply range and several power modes, making it suitable for battery‑powered data logging, sensor interfaces, wearables, and portable instrumentation. The IPZR suffix indicates a specific TI package/temperature variant; check the datasheet for exact pin count, package type, and temperature range. Development is via Code Composer Studio with MSP430Ware/MSP430 examples. For precise specs, refer to the MSP430FR69891 datasheet and user guide.
