Overview
MSP430FR5986IPM from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller in 64-pin LQFP package, featuring 48KB FRAM, 2KB RAM, 12-bit ADC with 12 external inputs, AES256 encryption, and extended scan interface (ESI) for precision analog sensing. It operates from 1.8 V to 3.6 V and targets battery-powered utility metering and data logging.
For engineers reviewing the MSP430FR5986IPM datasheet, MSP430FR5986IPM pinout, MSP430FR5986IPM application, or MSP430FR5986IPM equivalent, key selection criteria include FRAM endurance (1015 writes), RTC current in LPM3.5 (0.35 µA), ESI-based capacitive sensing capability, and UART/I²C bootloader support - all confirmed for this exact variant.
Technical Context
The MSP430FR5986IPM integrates a 16-bit CPUXV2 core with FRAM-based unified memory architecture, enabling simultaneous code execution and nonvolatile data storage without erase cycles. Its clock system combines DCO (up to 16 MHz), LFXT (32 kHz crystal), and HFXT (up to 24 MHz) with automatic calibration.
Peripherals include three eUSCI modules (two UART/I²C-capable, one SPI-only), five 16-bit timers (TA0–TA3, TB0), CRC16/CRC32 accelerators, and an ESI subsystem supporting background water/heat/gas volume measurement via capacitive sensing - all active in low-power modes including LPM3.5.

The device also supports external HFXT crystals up to 24 MHz for precision timing-critical applications.
Does the MSP430FR5986IPM support hardware AES encryption?
Yes, the MSP430FR5986IPM includes a dedicated 128/256-bit AES security coprocessor with true random number seed generation. This hardware engine performs encryption/decryption independently of the CPU, enabling secure firmware updates and encrypted telemetry without compromising real-time performance or increasing power consumption during cryptographic operations.
How many ADC input channels does the MSP430FR5986IPM support?
The MSP430FR5986IPM integrates a 12-bit ADC12_B module with up to 12 external analog input channels. It supports both single-ended and differential acquisition modes, internal reference (1.5 V or 2.5 V), and sample-and-hold functionality - all confirmed in the SLAS789D datasheet for this specific variant.
Is the MSP430FR5986IPM pin-compatible with other devices in the FR598x family?
Yes, the MSP430FR5986IPM in 64-pin LQFP (PM) package shares identical pinout and electrical characteristics with MSP430FR5987IPM and MSP430FR5988IPM. All three variants support drop-in replacement within the same footprint, enabling scalable FRAM capacity selection without PCB redesign.
What low-power modes are available on the MSP430FR5986IPM?
The MSP430FR5986IPM offers seven optimized low-power modes: LPM0–LPM4, plus LPM3.5 and LPM4.5. Key states include LPM3.5 (0.35 µA with RTC active) and LPM4.5 (0.02 µA shutdown), both verified in SLAS789D Section 5.9.
