Product details
Overview
MSP430FR6889IPNR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 128KB nonvolatile memory, 2KB RAM, integrated 12-bit ADC (16-channel), LCD controller (up to 320 segments), and real-time clock. It operates from 1.8 V to 3.6 V and supports seven low-power modes-including LPM4.5 (0.02 µA typical)-targeting battery-powered utility metering and data logging.
For engineers reviewing the MSP430FR6889IPNR datasheet, MSP430FR6889IPNR pinout, MSP430FR6889IPNR application, or MSP430FR6889IPNR equivalent, key selection criteria include FRAM endurance (1015 write cycles), capacitive touch I/O support across all ports P1–P10/PJ, RTC calendar/alarm functionality, and dual eUSCI modules supporting UART/IrDA/SPI/I²C with hardware bootloader.
Technical Context
The MSP430FR6889IPNR implements the CPUXV2 core with 16 registers and integrates a 32-bit hardware multiplier, three-channel DMA, and CRC16/CRC32 accelerators. Its clock system combines factory-trimmed DCO (10 frequencies), LFXT (32-kHz crystal), HFXT, and VLO for flexible low-power timing.
Analog subsystem includes a 16-channel comparator, programmable reference (VREF+/VREF−), sample-and-hold, and LCD_C module with contrast control and static/2–8-mux support. All I/O ports (P1–P10, PJ) support capacitive touch sensing without external components and edge-selectable wake-up from LPM.

Does the MSP430FR6889IPNR support capacitive touch sensing on all I/O pins?
Yes, the MSP430FR6889IPNR supports capacitive touch sensing on all P1–P10 and PJ port pins without external components. This capability is implemented via the integrated CTSIO module and is confirmed in the device overview section of the SLASE33C datasheet, enabling robust, sealed front-panel interfaces in utility meters and medical devices.
What LCD configurations does the MSP430FR6889IPNR support?
The MSP430FR6889IPNR's LCD_C module supports static, 2-, 3-, 4-, 6-, and 8-mux configurations with up to 320 total segments. It includes programmable contrast control, internal charge pump, and dedicated segment/common drivers - eliminating need for external LCD bias ICs in applications like water meter displays.
How does the FRAM memory in MSP430FR6889IPNR differ from traditional flash in terms of endurance and speed?
The MSP430FR6889IPNR's 128KB FRAM offers 1015 write cycles - orders of magnitude higher than flash - and performs writes at 125 ns per word with no erase-before-write requirement. This enables reliable, high-frequency data logging and firmware updates without wear leveling or latency penalties inherent to flash memory.
Is the MSP430FR6889IPNR pin-compatible with other devices in the MSP430FR68xx family?
The MSP430FR6889IPNR uses the LQFP-80 (PN) package and shares identical pinout with MSP430FR6879IPN and MSP430FR6887IPN.
