MSP430FR5043IPMR

The MSP430FR5043IPMR is TI’s low‑power, 16‑bit MSP430 microcontroller from the FRAM (FRAM) family. It uses ferroelectric RAM for fast, high‑endurance non‑volatile storage, enabling quick startup and reliable data retention with low energy.
Key points:
- Core: 16‑bit RISC CPU with multiple low‑power modes and fast wake‑up.
- Memory: on‑chip FRAM (tens of KB range) plus SRAM for runtime data.
- Peripherals: serial interfaces (UART/SPI/I2C), DMA, timers, ADC (and analog features), DAC where supported, and an LCD driver for segment LCDs.
- Power: optimized for battery-powered sensing, wearables, and HMI; designed for ultra‑low power with deep sleep capabilities.
- Package/ID: IPMR denotes the specific package and temperature grade; check TI for exact package (e.g., QFN/TSSOP) and pin count.
- Development: supported by Code Composer Studio and MSP430Ware with example projects and debugging tools.
Use cases include energy‑efficient data logging, portable sensors, and compact embedded systems needing frequent non‑volatile memory writes.

Here are the key features of the MSP430FR5043IPMR (FRAM-based MSP430 MCU):
- 16‑bit MSP430 CPU with Harvard architecture and ultra-low-power operation
- On-chip nonvolatile FRAM memory for program and data (high endurance, fast writes)
- Wide supply range: typically 1.8–3.6 V; suitable for battery-powered apps
- Flexible clock system with rapid wakeup and multiple low-power modes
- Peripherals:
- eUSCI_B module: UART, SPI, and I2C
- 12‑bit SAR ADC (multiple channels) and analog comparator
- Optional analog features (e.g., op-amp, depending on device variant)
- Timers (16‑bit Timer_A/Capture/Compare), watchdog timer
- DMA controller for memory/peripheral transfers
- CRC engine for data integrity
- Real-time clock/backup domain (where supported)
- Security and reliability features: reset supervisor/brown-out reset
- Debug support: Spy-Bi-Wire (SBW) and JTAG
- Packaging: IPMR variant (specific pin count/layout per TI datasheet)
Note: Exact FRAM size, peripherals, and temperature range are device-specific—check the TI datasheet for the precise configuration of MSP430FR5043IPMR.
