Product details
Overview
MSP430FR5986IPMR from Texas Instruments is an ultra-low-power 16-bit FRAM microcontroller designed for battery-operated metering and sensing applications. It integrates 48KB of nonvolatile FRAM, 2KB RAM, a 12-bit ADC with 12 external inputs, three 16-bit timers (TA0–TA2), two eUSCI modules (UART/IrDA/SPI + I2C/SPI), AES256 encryption, and an Extended Scan Interface (ESI) for capacitive sensing - all operating from 1.8 V to 3.6 V.
For engineers reviewing the MSP430FR5986IPMR datasheet, MSP430FR5986IPMR pinout, MSP430FR5986IPMR application, or MSP430FR5986IPMR equivalent, key selection considerations include FRAM endurance (1015 writes), RTC operation at 0.35 µA in LPM3.5, ESI-based water/heat metering capability, and compatibility with TI's EnergyTrace++™ development tools.
Technical Context
The MSP430FR5986IPMR implements the ULP CPUXV2 core with seven low-power modes, including LPM3.5 (RTC active, 0.35 µA) and LPM4.5 (shutdown, 0.02 µA). Its FRAM memory architecture enables byte-level writes without erase cycles and eliminates flash write latency.
It features dual eUSCI modules: eUSCI_A0 supports UART with auto-baud detection and IrDA; eUSCI_B0 supports I2C with multi-slave addressing and SPI. The ESI peripheral operates autonomously for background capacitance measurement, supporting up to 16-channel extended scan without CPU intervention.

FAQ
What is the maximum operating frequency of the MSP430FR5986IPMR?
The MSP430FR5986IPMR operates at up to 16 MHz using its factory-trimmed DCO oscillator or external HFXT crystal. This frequency is fully supported across all supply voltages (1.8 V–3.6 V) and low-power modes where active CPU operation is permitted, enabling real-time signal processing in metering applications without compromising energy efficiency.
Does the MSP430FR5986IPMR support hardware-based AES encryption?
Yes, the MSP430FR5986IPMR includes a dedicated AES256 security coprocessor with true random number generation. This hardware engine accelerates encryption/decryption operations independently of the CPU, reducing latency and power consumption versus software implementations - essential for secure bootloader (BSL) updates and encrypted sensor data in smart meters.
How many external ADC input channels does the MSP430FR5986IPMR provide?
The MSP430FR5986IPMR integrates a 12-bit ADC12_B module with up to 12 external analog input channels. These inputs are mapped to pins P1.0–P1.7, P4.0–P4.7, and P5.4–P5.7, supporting single-ended and differential acquisition with internal reference and sample-and-hold - sufficient for multi-sensor metering front-ends.
What low-power modes are available on the MSP430FR5986IPMR, and what is the lowest current draw?
The MSP430FR5986IPMR supports seven low-power modes, including LPM3.5 (RTC active, 0.35 µA typical) and LPM4.5 (full shutdown, 0.02 µA typical). LPM4.5 disables all clocks and RAM retention, making it ideal for long-term storage or deep sleep between metering events - extending primary battery life beyond a decade in static installations.
Is the MSP430FR5986IPMR pin-compatible with other devices in the MSP430FR59xx family?
Yes, the MSP430FR5986IPMR in the 64-pin LQFP (PM) package shares identical pinout and electrical characteristics with MSP430FR5987IPMR and MSP430FR5988IPMR. This allows direct PCB footprint reuse across variants - simplifying design scalability when upgrading FRAM capacity without layout changes.
