For designs that log sensor data, store calibration constants, or support over-the-air firmware updates, FRAM eliminates the wear-leveling and write-cycle budgeting that Flash-based MCUs require. The 64 KB program space is complemented by 2 KB of SRAM for stack and temporary variables. ## Peripherals and integration","metaTitle":"TI MSP430FR5859IRHAT 16-bit MCU, 16 MHz, 64KB FRAM, 40-VQFN","metaDescription":"MSP430FR5859IRHAT from TI: 16-bit MSP430 CPUXV2, 16 MHz, 64KB FRAM, 2KB RAM, 14-ch 12-bit ADC, I²C/SPI/UART, -40°C to 85°C, 40-VQFN.
