Product details
Overview
MSP430FR6979IPZR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 128KB ferroelectric RAM (FRAM), 2KB SRAM, integrated LCD driver supporting up to 320 segments, 12-bit ADC with 16 external inputs, and dual eUSCI modules supporting UART, SPI, and I²C. It operates from 1.8 V to 3.6 V and targets battery-powered utility metering and data logging systems.
For engineers reviewing the MSP430FR6979IPZR datasheet, MSP430FR6979IPZR pinout, MSP430FR6979IPZR application, or MSP430FR6979IPZR equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), RTC current draw in LPM3.5 (0.35 µA), LCD segment count (320), AES256 encryption coprocessor, and 100-pin LQFP package compatibility with industrial metering layouts.
Technical Context
The MSP430FR6979IPZR implements the MSP430 CPUXV2 core with 16 general-purpose registers and executes instructions at up to 16 MHz. Its clock system integrates DCO (factory-trimmed to 10 frequencies), LFXT (32-kHz crystal), and HFXT (high-frequency crystal) sources - though HFXT is functional only on MSP430FR697x devices, not FR692x variants.
Peripherals include three 16-bit Timer_A modules (TA0, TA1, TA2, TA3), one 16-bit Timer_B (TB0) with seven capture/compare registers, CRC16/CRC32 hardware accelerators, and a 32-bit hardware multiplier. The device supports capacitive touch sensing across all P1–P10 and PJ ports without external components.

FAQ
What is the maximum operating frequency of the MSP430FR6979IPZR?
The MSP430FR6979IPZR operates at up to 16 MHz using its digitally controlled oscillator (DCO), which offers 10 factory-trimmed frequencies. This frequency supports real-time sensor processing and communication stack execution while maintaining ultra-low-power efficiency across all active and low-power modes.
Does the MSP430FR6979IPZR support hardware encryption?
Yes, the MSP430FR6979IPZR includes a dedicated AES256 security coprocessor with true random number generation. This enables fast, low-power encryption and decryption of stored data and communication payloads - essential for compliance with DLMS/COSEM and EN 13757-4 standards in utility metering applications.
How many LCD segments can the MSP430FR6979IPZR drive?
The MSP430FR6979IPZR drives up to 320 segments via its LCD_C module with support for static, 2-, 3-, 4-, 6-, or 8-multiplex configurations. This capability eliminates the need for external LCD drivers in advanced utility meters and portable instrumentation displays.
What is the typical current consumption of the MSP430FR6979IPZR in RTC-only mode?
In LPM3.5 mode with only the real-time clock active, the MSP430FR6979IPZR draws 0.35 µA typical. This ultra-low current enables decade-long battery operation in water and heat meters, assuming standard CR2450 or AA alkaline cells with appropriate energy budgeting.
Is the MSP430FR6979IPZR pin-compatible with other devices in the MSP430FR697x family?
Yes, the MSP430FR6979IPZR shares identical pinout and package (100-pin LQFP, PZ) with MSP430FR6977IPZR and MSP430FR69791IPZR. Firmware and PCB designs are interchangeable across these variants, differing only in FRAM size (128KB vs. 64KB) and boot loader interface (UART vs. I²C).
