Compare that to a conventional Flash MCU where a page-write takes milliseconds and pulls milliamps. For a firmware engineer, this means the MSP430FR6979IPZ can treat its program memory almost like RAM — store calibration constants, log sensor data, or update a bootloader without wear-leveling or erase cycles. The 2K x 8 RAM handles stack and temporary variables; the FRAM carries the persistent payload. This part carries an end-of-life (hot) status. TI has issued a last-time-buy notice; new factory orders are no longer being accepted. ## I/O and serial interfaces 63 general-purpose I/O lines are brought out on the 100-LQFP. The connectivity block includes I2C, SPI, UART/USART, and IrDA — enough to talk to external sensors, displays, or a radio module without bit-banging. The 12-bit ADC with 16 multiplexed channels handles analog inputs like thermocouples or current shunts.","metaTitle":"TI MSP430FR6979IPZ 16-Bit MCU, 16MHz, 128KB FRAM, 100-LQFP","metaDescription":"MSP430FR6979IPZ from TI: 16-bit MCU with 128KB FRAM, 16MHz CPU, 63 I/O, I2C/SPI, -40°C to 85°C.
