Product details
Overview
MSP430FR5989IPMR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 128KB ferroelectric RAM (FRAM), 2KB SRAM, 16-channel 12-bit ADC, integrated extended scan interface (ESI) for metering, and AES256 encryption. It operates from 1.8 V to 3.6 V and delivers 100 µA/MHz active current, enabling multi-year battery life in water/heat meters and portable data loggers.
For engineers reviewing the MSP430FR5989IPMR datasheet, MSP430FR5989IPMR pinout, MSP430FR5989IPMR application, or MSP430FR5989IPMR equivalent, key selection criteria include FRAM endurance (1015 writes), RTC with calendar mode (0.35 µA LPM3.5), ESI peripheral for capacitive sensing, and 64-pin LQFP package compatibility with industrial metering PCB layouts.
Technical Context
The MSP430FR5989IPMR implements the MSP430 CPUXV2 core with 16 general-purpose registers and executes instructions at up to 16 MHz. Its power architecture supports seven low-power modes-including LPM3.5 (RTC active, 0.35 µA) and LPM4.5 (shutdown, 0.02 µA)-optimized for intermittent sensing and long sleep cycles in battery-powered utility meters.
Peripherals are tightly coupled to the FRAM-based memory map: the 32-bit hardware multiplier (MPY32), three-channel DMA, CRC16/CRC32 engines, and ESI operate directly on FRAM without SRAM buffering. The ESI supports background analog front-end scanning across up to 16 channels for liquid/gas volume measurement without CPU intervention.

FAQ
What is the maximum operating frequency of the MSP430FR5989IPMR?
The MSP430FR5989IPMR supports a maximum system clock frequency of 16 MHz using the factory-trimmed DCO or external HFXT crystal. This enables real-time signal processing for ESI-based metering while maintaining sub-100 µA/MHz active current efficiency. All timing-critical peripherals-including Timer_A, ADC12_B, and eUSCI modules-are fully operational at 16 MHz.
Does the MSP430FR5989IPMR support hardware encryption?
Yes, the MSP430FR5989IPMR integrates a dedicated AES256 security coprocessor with true random number generation capability. This enables full-cycle encryption/decryption of FRAM-stored data and secure bootloader operations without CPU intervention-meeting IEC 62443-3-3 requirements for secure firmware updates in smart metering applications.
How does the Extended Scan Interface (ESI) function in the MSP430FR5989IPMR?
The ESI in the MSP430FR5989IPMR is a programmable analog front-end that performs autonomous capacitive or current-based sensing across up to 16 channels. It operates independently of the CPU during LPM3, scanning electrodes for water/heat meter electrodes and storing results directly to FRAM-reducing active CPU time by up to 92% compared to polled ADC acquisition.
What package type and dimensions does the MSP430FR5989IPMR use?
The MSP430FR5989IPMR uses a 64-pin LQFP (PM) package measuring 10 mm × 10 mm with 0.5-mm lead pitch and an exposed thermal pad. TI recommends connecting the thermal pad to VSS for optimal thermal performance and EMI suppression in high-density metering PCB layouts.
Can the MSP430FR5989IPMR operate from a single 3.0-V coin cell battery?
Yes, the MSP430FR5989IPMR operates across 1.8 V to 3.6 V, making it compatible with standard CR2032 (3.0 V nominal) and BR2032 (3.0 V) batteries. Its LPM4.5 shutdown current of 0.02 µA and LPM3.5 RTC current of 0.35 µA enable >12-year operation on a single CR2032 when paired with optimized duty cycling and FRAM-based data compression in the MSP430FR5989IPMR firmware.
