Unlike Flash, FRAM tolerates byte-by-byte writes at full speed with no erase cycle, so you can treat a portion of the 64 KB as non-volatile data storage — calibration constants, last-known state, event logs — without a dedicated EEPROM chip. The 2 KB of SRAM handles stack and scratchpad. End-of-life hot flag and Active product status. Confirm lifecycle status before multi-year BOM. Sourced to order against RFQ; availability and pricing at quote time. Brown-out detect, POR, DMA, PWM, WDT. Internal oscillator.","metaTitle":"TI MSP430FR5849IRHAR 16-bit MCU, 16 MHz, 64 KB FRAM, 40-VQFN","metaDescription":"MSP430FR5849IRHAR 16-bit MCU with 64 KB FRAM, 2 KB RAM, 14x12-bit ADC, 33 I/O, -40°C to 85°C.
