Overview

MSP430FR5987IPM from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller in 64-pin LQFP package, featuring 64KB nonvolatile FRAM, 2KB RAM, 12-bit ADC with 12 external inputs, RTC with calendar, and integrated ESI for metering applications. It operates from 1.8 V to 3.6 V and delivers 100 µA/MHz active current.

For engineers reviewing the MSP430FR5987IPM datasheet, MSP430FR5987IPM pinout, MSP430FR5987IPM application, or MSP430FR5987IPM equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), ESI peripheral support for water/heat metering, low-power RTC operation (0.35 µA in LPM3.5), AES256 security coprocessor, and UART/I²C serial interfaces with hardware bootloader.

Technical Context

The MSP430FR5987IPM implements the MSP430 CPUXV2 core with 16 registers and executes instructions at up to 16 MHz using DCO, HFXT, or LFXT clock sources. Its power architecture supports seven low-power modes including LPM3.5 (RTC active) and LPM4.5 (shutdown at 0.02 µA).

It integrates the Extended Scan Interface (ESI) for capacitive sensing in utility metering, three-channel DMA, 32-bit hardware multiplier, CRC16/CRC32 engines, and dual eUSCI modules-eUSCI_A0/A1 supporting UART/IrDA/SPI and eUSCI_B0/B1 supporting I²C/SPI-with hardware UART and I²C bootloaders.
