Typical applications include sensor nodes, metering, industrial control, and battery-powered instrumentation where low power and non-volatile data logging are critical. FRAM writes at bus speed with no erase cycle overhead, unlike Flash. For a firmware engineer, this means you can treat the 64 KB program space as a unified memory: store calibration constants, configuration tables, and data logs alongside code without wear-leveling or sector management. The 2K x 8 RAM handles stack and scratchpad. The 14-channel 12-bit ADC samples analog inputs directly — no external converter needed for mixed-signal sensor front-ends. The base product number is MSP430FR5859, covering multiple package and temperature variants within the family.","metaTitle":"Texas Instruments MSP430FR5859IRHAR MCU, 16-bit, 16 MHz","metaDescription":"Texas Instruments MSP430FR5859IRHAR 16-bit MCU with 64 KB FRAM, 2K x 8 RAM, 33 I/O, 14x12-bit ADC, 1.8V-3.6V supply, -40°C to 85°C.
