Product details
Overview
MSP430FR6879IPZ from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 128KB ferroelectric RAM (FRAM), 2KB SRAM, integrated 12-bit ADC with 16 external inputs, LCD driver supporting up to 320 segments, and dual eUSCI modules (UART/IrDA/SPI/I²C). It operates from 1.8 V to 3.6 V and targets battery-powered metering applications requiring long-term data retention and low active/standby current.
For engineers reviewing the MSP430FR6879IPZ datasheet, MSP430FR6879IPZ pinout, MSP430FR6879IPZ application, or MSP430FR6879IPZ equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), RTC with calendar/alarm in LPM3.5 (0.35 µA), capacitive touch I/O on all ports P1–P10/PJ, and dual 16-bit timers with up to 7 capture/compare registers per timer.
Technical Context
The MSP430FR6879IPZ implements the CPUXV2 16-bit RISC core with 16-MHz max clock, paired with a flexible clock system including DCO (10 factory-trimmed frequencies), LFXT (32-kHz crystal), and HFXT. Its power architecture supports seven low-power modes, with LPM3.5 enabling real-time clock operation at 0.35 µA using an external 3.7-pF crystal.
Peripherals include three 16-bit Timer_A modules (TA0/TA1/TA3), two Timer_B modules (TB0/TB1), 32-bit hardware multiplier, three-channel DMA, CRC16/CRC32 engines, and dual eUSCI_A (UART/IrDA/SPI) and eUSCI_B (I²C/SPI) interfaces - all accessible via multiplexed I/O pins across 100-pin LQFP package.

FAQ
What is the maximum operating frequency of the MSP430FR6879IPZ?
The MSP430FR6879IPZ supports a maximum system clock frequency of 16 MHz using the integrated digitally controlled oscillator (DCO) or external HFXT crystal. This allows real-time execution of metrology algorithms and fast FRAM writes while maintaining sub-100 µA/MHz active-mode current efficiency.
Does the MSP430FR6879IPZ support capacitive touch sensing without external components?
Yes, the MSP430FR6879IPZ supports capacitive touch sensing on all I/O pins across ports P1–P10 and PJ. It uses built-in charge-transfer circuitry and software libraries (e.g., CapTIvate™) to implement button, slider, and wheel interfaces without external RC networks or dedicated touch controllers.
What is the FRAM endurance specification for the MSP430FR6879IPZ?
The MSP430FR6879IPZ features 128 KB of ferroelectric RAM rated for 10¹⁵ write cycles - orders of magnitude higher than flash or EEPROM. This enables daily logging of hundreds of records over 20+ years without wear-out concerns, critical for utility metering deployments.
How does the MSP430FR6879IPZ achieve 0.35 µA RTC current in LPM3.5 mode?
The MSP430FR6879IPZ achieves 0.35 µA RTC current in LPM3.5 by powering only the RTC module and 32-kHz crystal oscillator (LFXT) while shutting down the CPU, FRAM, and all other peripherals. An external 3.7-pF crystal on PJ.4/PJ.5 is required to meet this specification.
Is the MSP430FR6879IPZ pin-compatible with other devices in the MSP430FR687x family?
Yes, the MSP430FR6879IPZ in the 100-pin LQFP (PZ) package shares identical pinout and electrical characteristics with MSP430FR6877IPZ and MSP430FR68791IPZ - enabling hardware reuse across variants differing only in FRAM size or bootloader interface.
