For a data-logging endpoint that writes a 32-byte record every second, a Flash part would need wear-leveling firmware; this part handles it natively. The 32 KB program space also stores calibration constants or boot parameters in the same array, saving a serial EEPROM footprint. ## Package and supply — 40-VQFN with exposed pad The internal oscillator trims to 16 MHz, though an external crystal can be used for tighter timing. ## Industrial temperature and connectivity Brown-out detect and POR are integrated, reducing external supervisor IC cost. ## Lifecycle and sourcing Standard lead times apply through the distribution channel. For a new design, this part carries no supply-risk flag.","metaTitle":"TI MSP430FR5857IRHAT 16-bit MCU, 16 MHz, 32 KB FRAM, 40-VQFN","metaDescription":"Texas Instruments MSP430FR5857IRHAT 16-bit MCU with 16 MHz CPU, 32 KB FRAM, 14x12-bit ADC, 33 I/O.
