Product details
Overview
MSP430FR6988IPN from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller in 80-pin LQFP package, featuring 96KB nonvolatile FRAM, 2KB RAM, 12-bit ADC with 16 external inputs, integrated LCD driver (up to 320 segments), and Extended Scan Interface (ESI) for precision metering. It operates from 1.8 V to 3.6 V and targets battery-powered utility meters requiring RTC, low-power sensing, and secure firmware storage.
For engineers reviewing the MSP430FR6988IPN datasheet, MSP430FR6988IPN pinout, MSP430FR6988IPN application, or MSP430FR6988IPN equivalent, key selection criteria include FRAM endurance (1015 writes), ESI-based background measurement capability, AES256 encryption coprocessor, and LPM3.5 RTC current (0.35 µA typical) - all critical for long-life, tamper-resistant metering designs.
Technical Context
The MSP430FR6988IPN implements the ULP CPUXV2 core with seven low-power modes, including LPM3.5 (RTC active) and LPM4.5 (shutdown at 0.02 µA). Its clock system integrates DCO (10 factory-trimmed frequencies), LFXT (32-kHz crystal), and HFXT support, enabling precise timing for calendar functions and synchronous peripherals.
Peripherals include dual eUSCI_A (UART/IrDA/SPI) and dual eUSCI_B (I²C/SPI) modules, three-channel DMA, 32-bit hardware multiplier, CRC16/CRC32 engines, and five 16-bit timers (TA0–TA3, TB0) with up to seven capture/compare registers per timer - optimized for pulse counting, waveform generation, and sensor signal processing in metering applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power FRAM microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR6989IPN | 128KB FRAM, identical pinout and peripheral set - differs only in memory size and ordering code. | Preferred where firmware complexity or data logging depth exceeds 96KB capacity. | Select MSP430FR6989IPN if future firmware growth or extended historical data retention is required; same PCB layout and software compatibility. |
| MSP430FR5988IPM | 96KB FRAM but in 64-pin LQFP (10 mm × 10 mm); lacks LCD_C and ESI peripherals; reduced I/O count (48 vs 83). | Suitable for compact, non-display, non-metering applications like simple sensor nodes or battery monitors. | Choose MSP430FR5988IPM only when display and ESI are unnecessary and board space is constrained - not a drop-in replacement. |
