MSP430FR5994IPMR

MSP430FR5994IPMR is TI’s MCU from the MSP430 FRAM family. It combines a 16‑bit MSP430 RISC core with large nonvolatile FRAM memory, enabling fast, persistent program and data storage with ultra‑low power. FRAM provides near-RAM speed and nonvolatility for long battery life and frequent writes.
Key points:
- FRAM memory: persistent, fast writes, low standby power (no external flash needed).
- Rich analog/digital peripherals: multi-channel 12‑bit ADC, DACs, comparators, op‑amps, timers, DMA, and UART/SPI/I2C serial interfaces.
- Low‑power design: multiple low-power modes with fast wake-up for battery‑powered sensing and data logging.
- Suitable for data logging, portable meters, sensor hubs, and IoT edge devices.
- Tools: TI development ecosystem (Code Composer Studio, MSP430Ware, etc.).
IPMR denotes a specific device/package/temperature option within the MSP430FR59xx family.
