MSP430FR2673TRHBT Key Features
- Single 16-bit MSP430 core for efficient control and low instruction overhead, yielding faster control loops per clock cycle.
- Integrated FRAM for higher write endurance and near-instant nonvolatile writes compared with flash, reducing write latency and extending device lifetime in logging use.
- Low-voltage operation (1.8?C3.6 V) and multiple low-power modes for reduced standby energy consumption in battery-powered systems.
- On-chip 12-bit ADC and multiple timers to simplify mixed-signal integration and reduce component count in measurement and control applications.
Typical Applications
- Battery-powered sensor nodes that require long-term data logging and frequent nonvolatile writes, where FRAM enables rapid writes with lower energy per write over flash-based alternatives.
- Industrial control endpoints that need deterministic 16-bit control timing, robust analog measurement with 12-bit resolution, and multiple serial buses for fieldbus or peripheral connectivity.
- Portable medical devices that demand low active and standby currents, precise ADC measurements, and rapid nonvolatile storage for patient event logging and configuration parameters.
- Smart metering and utility monitoring where high write endurance, low power, and reliable operation across -40 ??C to 85 ??C ensure long-term data integrity and minimal maintenance.
MSP430FR2673TRHBT Advantages vs Typical Alternatives
The FRAM-based MSP430FR2673TRHBT offers faster nonvolatile writes and higher write endurance than many flash-based microcontrollers, which reduces latency for logging tasks and increases system lifetime. With a 16-bit core and low-voltage operation, it delivers comparable control performance with lower energy consumption compared with higher-bit alternatives. Integration of ADC, timers, and multiple serial interfaces reduces BOM and PCB area compared with discrete solutions.
