Product details
Overview
MSP430FR5988IPM from Texas Instruments is an ultra-low-power 16-bit FRAM microcontroller designed for battery-operated metering and sensing applications. It integrates 96KB of nonvolatile FRAM, 2KB RAM, a 12-bit ADC with 12 external inputs, RTC with calendar, and Extended Scan Interface (ESI) for capacitive fluid/gas measurement. Its LPM3.5 mode draws just 0.35 µA while maintaining RTC operation - ideal for water/heat meters requiring decade-scale battery life.
For engineers reviewing the MSP430FR5988IPM datasheet, MSP430FR5988IPM pinout, MSP430FR5988IPM application, or MSP430FR5988IPM equivalent, key selection criteria include FRAM endurance (1015 writes), ESI peripheral support for background analog sensing, integrated AES256 encryption, and compatibility with TI's EnergyTrace++ power profiling tools in active and low-power modes.
Technical Context
The MSP430FR5988IPM implements a ULP CPUXV2 core with seven programmable low-power modes, including LPM3.5 (RTC active, FRAM retained) and LPM4.5 (0.02 µA shutdown). Its clock system combines factory-trimmed DCO, LFXT (32 kHz crystal), and HFXT (up to 8 MHz) sources, enabling precise timing control across operating conditions.
Peripherals are organized into autonomous domains: ESI operates independently during LPM3 to scan up to 16 channels without CPU intervention; DMA handles data movement between ADC, FRAM, and peripherals; and the 32-bit CRC engine supports ISO-3309 and CCITT standards for firmware integrity verification.

FAQ
What is the maximum operating frequency of the MSP430FR5988IPM?
The MSP430FR5988IPM supports a maximum system clock frequency of 16 MHz using its factory-trimmed DCO or external HFXT crystal. This allows high-speed computation for real-time sensor processing while maintaining ultra-low-power operation through dynamic clock gating and low-power mode transitions.
Does the MSP430FR5988IPM support hardware encryption?
Yes, the MSP430FR5988IPM integrates a dedicated AES256 security coprocessor with true random number seed generation. This enables secure firmware authentication, encrypted data logging to FRAM, and protected communication - all without consuming CPU cycles or increasing active-mode current.
How does the Extended Scan Interface (ESI) function in the MSP430FR5988IPM?
The ESI in the MSP430FR5988IPM performs autonomous capacitive sensing on up to 16 channels during LPM3, using dedicated hardware to excite electrodes and digitize responses. It operates without CPU intervention, reducing system power and enabling continuous background monitoring for water/heat metering applications.
What low-power modes are available on the MSP430FR5988IPM?
The MSP430FR5988IPM offers seven low-power modes: LPM0–LPM4, plus LPM3.5 and LPM4.5. LPM3.5 maintains RTC and FRAM retention at 0.35 µA; LPM4.5 shuts down all clocks and supplies except for reset logic, drawing just 0.02 µA - optimized for long-term storage or infrequent wake-up events.
Is the MSP430FR5988IPM pin-compatible with other devices in the MSP430FR59xx family?
Yes, the MSP430FR5988IPM in LQFP-64 (PM) package shares identical pinout and electrical characteristics with MSP430FR5989IPM and MSP430FR5987IPM. This enables drop-in replacement across variants differing only in FRAM size (48KB/96KB/128KB), simplifying design scalability and inventory management.
