Industrial temperature range (-40°C to 85°C) and a supply range of 1.8 V to 3.6 V let this part run from two alkaline cells or a single Li-ion cell without a regulator.
The MSP430FR6989IPZR is flagged with an end-of-life (EOL) lifecycle stage.
On-chip peripherals include a 16-channel 12-bit ADC, a segment LCD controller, multiple serial interfaces (I²C, IrDA, SPI, UART/USART), and a PWM timer.
The MSP430FR5994 series (e.g., MSP430FR5994IPZ) is TI's recommended pin-compatible successor, offering higher FRAM density (up to 256 KB) while maintaining the same 100-LQFP footprint and peripheral set. For a drop-in replacement with identical memory, the MSP430FR6989IPZR itself remains available through the surplus channel.
The CPU core runs at 16 MHz, which is typical for the MSP430 FRAM family — enough for real-time control loops, display updates, and sensor polling without external oscillators.
Texas Instruments provides RoHS and REACH compliance declarations for this part. The 100-LQFP package is lead-free (RoHS compliant). No UL or IEC certification is listed for this MCU; those apply at the system level, not the component.
