FRAM can be partitioned into program and data segments. The 1.8 V to 3.6 V supply range allows direct connection to a 3.6 V Li-ion cell or two alkaline cells in series, and the low-voltage floor means the MCU can stay operational as the battery discharges, extending system runtime. The I²C and SPI ports handle common sensor and memory interfaces; the UART/USART modules support IrDA for wireless optical links if needed. Internal oscillator eliminates external crystal in many applications. Supports external low-frequency crystal for RTC. Active product status from Texas Instruments. Available through independent distribution; pricing confirmed at quote.","metaTitle":"TI MSP430FR5849IRHAT 16-bit MCU, 64KB FRAM, 16MHz, 40-VQFN","metaDescription":"Texas Instruments MSP430FR5849IRHAT, 16-bit MSP430 CPUXV2 MCU with 64KB FRAM, 2KB RAM, 14ch 12-bit ADC, 33 I/O, 1.8V-3.6V, -40°C to 85°C, 40-VQFN.
