Product details

Overview

MSP430FR6889IPN from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller in 80-pin LQFP package, featuring 128KB FRAM, 2KB RAM, 12-bit ADC with 16 external channels, integrated LCD driver for up to 320 segments, and RTC with calendar/alarm - deployed in battery-powered utility metering and portable medical data loggers.

For engineers reviewing the MSP430FR6889IPN datasheet, MSP430FR6889IPN pinout, MSP430FR6889IPN application, or MSP430FR6889IPN equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), LPM3.5 current (0.35 µA typical), 32-bit hardware multiplier, eUSCI_A/B dual UART/I²C/SPI support, and capacitive touch I/O on all ports P1–P10 without external components.

Technical Context

The MSP430FR6889IPN implements the MSP430 CPUXV2 core with seven low-power modes optimized for energy-constrained applications. Its FRAM memory architecture enables fast nonvolatile writes (125 ns/word) and eliminates erase-before-write latency, while the integrated LCD_C module supports static and multiplexed displays up to 8-backplane configurations.

Peripherals include five 16-bit timers (TA0–TA3, TB0) with up to seven capture/compare registers each, dual eUSCI_A (UART/IrDA/SPI) and eUSCI_B (I²C/SPI) modules, 16-channel analog comparator, and hardware CRC16/CRC32 engines - all operating across the full 1.8–3.6 V supply range with SVS protection.
