MSP430FR2100IRLLT Key Features
- 16-bit MSP430 core for efficient control and deterministic timing in real-time tasks.
- FRAM non-volatile memory that allows fast, high-endurance writes and preserves data without batteries.
- Ultra-low-power operation with multiple low-power modes to extend battery life or reduce standby energy.
- Compact package and pin count that simplify PCB layout for smaller or cost-sensitive designs.
- Integrated Timer_A and comparator to handle timing, measurement, and simple control without extra ICs.
Typical Applications
- Battery-powered metering and sensor nodes requiring frequent non-volatile data logging and long standby life across many months.
- Compact industrial controllers that need fast FRAM writes for configuration storage and repeated parameter updates without external EEPROM.
- Handheld instrumentation where low quiescent current, instant-on response, and small PCB footprint are priority design constraints.
- Simple motor or actuator controllers that use a single timer and comparator for basic PWM or threshold detection functions in tight spaces.
MSP430FR2100IRLLT Advantages vs Typical Alternatives
The device offers distinct advantages compared with many low-cost microcontrollers. Its FRAM gives faster writes and far higher endurance than typical flash or EEPROM, reducing write-time bottlenecks and improving reliability for frequent data updates. The ultra-low-power modes cut standby consumption compared to many mainstream MCUs, extending battery life. A small package and integrated peripherals reduce BOM count versus solutions that require external memory or timers.
