MSP430FR5964IRGZR Key Features
- One 16?bit core that provides efficient instruction density and lower code size compared with many 32?bit MCUs.
- Nonvolatile FRAM memory enabling fast writes and high endurance, which reduces write latency and extends data logging life.
- Low supply range and multiple low?power modes that matter for battery?operated, always?on systems where energy per operation is critical.
- Integrated 12?bit ADC and analog comparator for direct sensor interface, eliminating the need for many external components.
- Hardware serial controllers (UART/SPI/I2C) for easier integration with sensors, memories, and wireless modules, improving design time to market.
- 16?bit timers and DMA support that improve deterministic timing and offload CPU for higher system efficiency.
Typical Applications
- Battery?powered sensor modules that need low standby current and fast nonvolatile logging for frequent write cycles across many years.
- Industrial control nodes where deterministic 16?bit timing and integrated serial peripherals simplify connectivity to field buses and sensors.
- Portable medical devices requiring low power, nonvolatile storage, and a compact mixed?signal MCU to manage sensors and user interfaces.
- Consumer energy measurement and metering where frequent writes to nonvolatile memory, low power consumption, and integrated ADC reduce BOM and power.
MSP430FR5964IRGZR Advantages vs Typical Alternatives
The device offers faster nonvolatile writes and substantially higher write endurance versus traditional flash?based MCUs, enhancing reliability for frequent data logging. Its 16?bit core delivers denser code and lower active energy per instruction compared with many 32?bit parts, helping systems meet tight power budgets. Integrated 12?bit analog and multiple serial interfaces reduce external components and board area. In short, the MCU trades higher raw CPU width for efficiency, lower energy, and better nonvolatile write performance.
