MSP430FR2155TRHAT Technical Specifications

MSP430FR2155TRHAT Key Features

• Single 16-bit core with low-cycle instruction set for compact code and predictable timing.
• Embedded FRAM memory that enables fast writes and high endurance, improving data-logging reliability.
• Ultra-low power operation across active and standby modes to extend battery life in portable systems.
• Integrated analog and digital peripherals to reduce external components and simplify designs.

Typical Applications

• Battery-powered sensor nodes that require frequent nonvolatile logging and long standby intervals to maximize service life in remote installations.
• Handheld instrumentation where fast nonvolatile configuration saves settings instantly and reduces time to resume operation after power loss.
• Industrial metering endpoints that need deterministic 16-bit control, 12-bit analog acquisition, and low standby current for energy-smart installations.
• Consumer or medical wearable devices that benefit from compact packaging, low operating voltage, and integrated peripherals to minimize board area and cost.

MSP430FR2155TRHAT Advantages vs Typical Alternatives

The part combines 16-bit CPU efficiency with FRAM nonvolatile memory, offering faster in-field writes and higher endurance than EEPROM-based alternatives. At comparable clock rates, the device uses lower active and standby current than many mainstream microcontrollers, improving battery runtime. Its integrated ADC and serial blocks reduce external parts count versus discrete solutions. The small 20-pin package and 1.8?C3.6 V range make it more compact and flexible for low-voltage systems than larger-footprint 32-bit MCUs in similar roles.
