Product details
Overview
MSP430FR6887IPNR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 128KB nonvolatile memory, 2KB RAM, integrated 12-bit ADC, LCD driver (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 LPM3.5 (0.35 µA RTC active) and LPM4.5 (0.02 µA shutdown)-targeting battery-powered utility metering and data logging systems.
For engineers reviewing the MSP430FR6887IPNR datasheet, MSP430FR6887IPNR pinout, MSP430FR6887IPNR application, or MSP430FR6887IPNR equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), capacitive touch I/O without external components, dual eUSCI modules (UART/I²C/SPI), and integrated LCD bias generation for segment displays in metering front-ends.
Technical Context
The MSP430FR6887IPNR implements the MSP430 CPUXV2 core with 16 registers and executes instructions at up to 16 MHz. Its power architecture integrates SVS (supply voltage supervisor), LDO, and multiple clock sources-DCO (10 factory-trimmed frequencies), LFXT (32 kHz crystal), and HFXT-enabling precise timing control across operating modes.
Peripherals include three 16-bit Timer_A modules (TA0/TA1/TA3), two Timer_B modules (TB0/TB1), a 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 supporting capacitive touch sensing on all ports P1–P10 and PJ.

FAQ
What is the maximum operating frequency of the MSP430FR6887IPNR?
The MSP430FR6887IPNR supports a maximum system clock frequency of 16 MHz via its DCO or external HFXT oscillator. This enables real-time execution of metrology algorithms and fast FRAM writes (125 ns per word) while maintaining sub-100 µA/MHz active-mode efficiency-critical for responsive user interfaces and high-speed sensor sampling in the MSP430FR6887IPNR.
Does the MSP430FR6887IPNR support hardware encryption?
No, the MSP430FR6887IPNR does not include AES or other hardware cryptographic accelerators. It relies on software-based security primitives, including a true random number seed generator for cryptographic key derivation. For applications requiring FIPS-compliant encryption, external secure elements or higher-tier MSP430FR59xx devices with AES modules should be evaluated instead of the MSP430FR6887IPNR.
How many I/O pins support capacitive touch sensing on the MSP430FR6887IPNR?
All 83 general-purpose I/O pins across ports P1–P10 and PJ support capacitive touch sensing without external components. This capability is implemented in hardware via the CTSIO module and enables robust, low-power touch interfaces for sealed meter housings-directly leveraging the full I/O count of the MSP430FR6887IPNR in LQFP-80 packaging.
What LCD bias voltages does the MSP430FR6887IPNR generate internally?
The MSP430FR6887IPNR generates up to five internal LCD bias voltages (V1–V5) using its integrated LCD_C module and external capacitor network (e.g., R33/LCDCAP). These voltages drive common and segment lines for static or multiplexed (2–8 mux) displays up to 320 segments-eliminating external charge pumps or resistor ladders required by conventional MCU-based LCD solutions using the MSP430FR6887IPNR.
Is the MSP430FR6887IPNR pin-compatible with other MSP430FR687x devices?
Yes, the MSP430FR6887IPNR shares the same LQFP-80 (PN) package and pinout with MSP430FR6879IPN and MSP430FR6877IPN, enabling drop-in replacement in existing designs. However, functional differences exist-such as TA3 timer presence and FRAM size-so firmware and peripheral initialization must be validated before substitution of the MSP430FR6887IPNR.
