Product details
Overview
MSP430FR6988IPZR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller featuring 96KB nonvolatile FRAM, 2KB RAM, integrated LCD driver (up to 320 segments), 12-bit ADC with 16 external inputs, 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 MSP430FR6988IPZR datasheet, MSP430FR6988IPZR pinout, MSP430FR6988IPZR application, or MSP430FR6988IPZR 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 MSP430FR6988IPZR implements a 16-bit CPUXV2 core with seven optimized low-power modes, including LPM3.5 (RTC active) and LPM4.5 (shutdown at 0.02 µA). Its clock system integrates DCO, LFXT (32 kHz crystal), and HFXT (up to 16 MHz), enabling precise timing control for calendar functions and sensor sampling.
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 ESI - a dedicated analog front-end supporting capacitive, resistive, and impedance-based measurements without CPU intervention.

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 |
|---|---|---|---|
| MSP430FR6989IPZR | 128 KB FRAM, identical peripherals and pinout - differs only in FRAM size and part marking. | Preferred where extended firmware partitioning or larger data buffers are required (e.g., multi-tariff billing logs). | Select when future firmware growth headroom or >96 KB persistent data storage is needed; no hardware change required. |
| MSP430FR5988IPN | 96 KB FRAM, LQFP-80 package (12 mm × 12 mm), no LCD_C module - lacks 320-segment LCD driver and ESI. | Suitable for non-display, non-metering applications like sensor nodes or smart switches where ESI and LCD are unused. | Choose for space-constrained designs without display or metrology requirements; requires PCB redesign due to smaller package and missing peripherals. |
Compared with MSP430FR6988IPZR, the MSP430FR6989IPZR offers higher FRAM density in identical packaging for seamless firmware scalability, while the MSP430FR5988IPN trades LCD/ESI capability for reduced footprint and cost in simpler sensing roles - neither is pin-compatible without layout revision.
