MSP430FR5994IPMR

MSP430FR5994IPMR is TI’s MSP430 microcontroller in the FRAM-based MSP430FR59x family. It combines a 16‑bit MSP430 CPU with fast nonvolatile FRAM memory for code and data, plus RAM for runtime storage, enabling ultra‑low‑power operation with rapid wakeup.
Key points:
- Ultra‑low-power MCU for sensing/control in battery-powered devices.
- Memory: nonvolatile FRAM (fast writes) plus SRAM-backed data storage.
- Peripherals: ADC and analog comparators, multiple timers, UART/SPI/I2C via USCI, DMA, and an LCD segment driver.
- Power and operating range: supports low-voltage operation with several sleep modes to minimize energy use.
- Development: supported by TI tools (Code Composer Studio, MSP430Ware) and third‑party IDEs.
- Package: IPMR denotes a specific package variant; check TI’s product page for exact pin count and package details.
Typical uses include portable sensors, wearables, environmental monitors, and other battery‑powered embedded applications that benefit from fast FRAM access, low standby current, and a rich peripheral set.
