• Internal clocking with a low?frequency oscillator and DCO to reduce external component count and simplify PCB layout.

Typical Applications

• Battery?powered sensors that require frequent configuration updates and data logging, benefiting from FRAM??s high write endurance without flash wear?leveling.
• Portable medical devices and handheld instruments where low standby current and small package size reduce battery drain and PCB footprint.
• Smart meters and utility endpoints that need reliable non?volatile storage for event counts, calibration data, and intermittent power operation.
• Industrial controls and simple motor/actuator controllers that demand deterministic timing and low power in harsh temperature ranges.

MSP430FR2000IRLLR Advantages vs Typical Alternatives

The FRAM?based MSP430FR2000IRLLR offers faster, high?endurance non?volatile writes versus typical flash?based microcontrollers, reducing the need for complex wear?leveling and increasing reliability for frequent writes.
