This makes it a strong fit for applications that log data, update firmware in the field, or wake frequently from sleep to take a sensor reading and go back to idle. ## What the 16 MHz core and FRAM mean for the BOM The 16 MHz clock rate is the CPU's maximum — enough for a control loop sampling at tens of kilohertz, a UART at 115200 baud, or a sensor hub polling I²C and SPI peripherals. The FRAM program memory is the headline feature: 32 KB of FRAM (32K x 8) means writes are fast and low-energy, so you can store calibration constants, configuration tables, or data logs directly in program space without wearing out the memory. The 1K x 8 RAM is modest — sized for stack and temporary variables, not large buffers. ## Peripherals and I/O for sensor and actuator control On-chip peripherals include a brown-out detect, POR, DMA, PWM, and a watchdog timer. ## Lifecycle and sourcing For BOM planning, this part presents no last-time-buy risk today.","metaTitle":"TI MSP430FR58471IRHAT 16-bit MCU, 32KB FRAM, 16MHz, 40-VQFN","metaDescription":"Texas Instruments MSP430FR58471IRHAT 16-bit MCU with 32KB FRAM, 16MHz CPU, 14x12b ADC, -40 to 85°C.
