Typical Applications
- Battery?powered sensor nodes and data loggers that require frequent nonvolatile writes and lower power consumption across longer deployments.
- Industrial control and monitoring endpoints where deterministic 16?bit control and 12?bit analog measurement reduce system complexity and cost.
- Portable meters and handheld instruments that benefit from FRAM endurance and fast nonvolatile updates to maintain calibration and logs.
- Consumer or building automation nodes where UART, SPI and I2C peripherals enable integration with radios, sensors and power management ICs.
MSP430FR5969IRGZT Advantages vs Typical Alternatives
The device uses FRAM instead of flash, which gives faster nonvolatile writes and far higher endurance. This leads to more frequent in?system logging and configuration updates compared with flash?based MCUs. The 16?bit MSP430 core delivers comparable control performance with lower code density and lower dynamic power than many 32?bit alternatives. With integrated 12?bit ADC and multiple serial interfaces, the part reduces external components and board area, and supports single?cell systems with a 1.8?C3.6 V supply window.
