Product details
Overview
MSP430FR6987IPNR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 64KB ferroelectric RAM (FRAM), 2KB SRAM, integrated 12-bit ADC with up to 16 external inputs, extended scan interface (ESI) for metering, and LCD driver supporting up to 320 segments. It operates from 1.8 V to 3.6 V and targets battery-powered utility metering applications requiring long-term data retention and low active/standby current.
For engineers reviewing the MSP430FR6987IPNR datasheet, MSP430FR6987IPNR pinout, MSP430FR6987IPNR application, or MSP430FR6987IPNR equivalent, key selection criteria include FRAM endurance (1015 write cycles), RTC with calendar mode in LPM3.5 (0.35 µA), ESI peripheral for capacitive sensing in water/heat meters, and UART/I²C bootloader support - all validated for the 80-pin LQFP (PN) package.
Technical Context
The MSP430FR6987IPNR implements the MSP430 CPUXV2 core with 16 general-purpose registers and executes instructions at up to 16 MHz using a factory-trimmed DCO, HFXT, or LFXT clock source. Its power architecture supports seven low-power modes, including LPM3.5 (RTC active, 0.35 µA typical) and LPM4.5 (shutdown, 0.02 µA typical), enabled by integrated SVS and LDO regulation.
Peripherals include three eUSCI modules (eUSCI_A0/A1 for UART/IrDA/SPI; eUSCI_B0/B1 for I²C/SPI), five 16-bit timers (TA0–TA3, TB0), 32-bit hardware multiplier, 3-channel DMA, AES256 coprocessor, and ESI with dedicated analog front-end for background capacitance measurement - all accessible via multiplexed I/O on P1–P10 and PJ ports.

FAQ
What is the maximum operating frequency of the MSP430FR6987IPNR?
The MSP430FR6987IPNR supports a maximum CPU clock frequency of 16 MHz, achieved using the factory-trimmed DCO oscillator, HFXT crystal (up to 24 MHz), or LFXT crystal (32 kHz). This frequency enables real-time signal processing for ESI-based metering while maintaining sub-100 µA/MHz active current efficiency.
Does the MSP430FR6987IPNR include hardware encryption capabilities?
Yes, the MSP430FR6987IPNR integrates a dedicated AES256 security coprocessor with true random number generation support. This enables secure firmware updates, encrypted data storage in FRAM, and authenticated communication - critical for compliance in smart utility deployments.
What package type and pin count does the MSP430FR6987IPNR use?
The MSP430FR6987IPNR uses an 80-pin LQFP (PN) package measuring 12 mm × 12 mm. This package provides full access to all peripherals including ESI analog inputs, LCD segment/common drivers, dual eUSCI modules, and JTAG/SBW debug interface.
How much FRAM and SRAM does the MSP430FR6987IPNR include?
The MSP430FR6987IPNR integrates 64 KB of ferroelectric RAM (FRAM) and 2 KB of SRAM. The FRAM serves as unified nonvolatile memory for program code, runtime variables, and data logging - offering 1015 write cycles and 125 ns write speed without erase overhead.
Is the MSP430FR6987IPNR compatible with the MSP430FR6989IPNR in terms of pinout and software?
No - while both belong to the MSP430FR698x family and share identical peripheral sets and register maps, the MSP430FR6987IPNR (80-pin PN) has a different pinout than the MSP430FR6989IPNR (100-pin PZ). Software is binary-compatible, but PCB layout and signal routing must be redesigned for the 80-pin variant.
