Overview
MSP430FR6887IPZR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller in 100-pin LQFP package, featuring 128KB FRAM, 2KB RAM, 12-bit ADC with 16 external inputs, integrated LCD driver for up to 320 segments, and RTC with calendar/alarm-designed for battery-powered utility metering applications including water and heat meters.
For engineers reviewing the MSP430FR6887IPZR datasheet, MSP430FR6887IPZR pinout, MSP430FR6887IPZR application, or MSP430FR6887IPZR equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), LPM3.5 RTC current (0.35 µA typical), 16-channel analog comparator, eUSCI_A/B dual UART/I²C/SPI support, and capacitive touch I/O on all ports P1–P10/PJ without external components.
Technical Context
The MSP430FR6887IPZR implements the MSP430xV2 CPU core with 16 registers and supports seven low-power modes optimized for energy-constrained deployments. Its clock system integrates DCO (10 factory-trimmed frequencies), LFXT (32-kHz crystal), HFXT (high-frequency crystal), and VLO, enabling precise timing control across active and standby states.
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 mapped to multiplexed I/O pins with configurable pullup/pulldown and edge-selectable wake-up from LPM.

FAQ
What is the maximum operating frequency of the MSP430FR6887IPZR?
The MSP430FR6887IPZR operates at up to 16 MHz using its factory-trimmed DCO or external HFXT crystal. This frequency supports real-time metrology calculations while maintaining ultra-low active-mode current (~100 µA/MHz). The device's CPUXV2 core executes instructions in single-cycle mode at this speed, enabling deterministic response for time-critical sensor sampling and communication tasks within the MSP430FR6887IPZR architecture.
Does the MSP430FR6887IPZR support hardware encryption?
The MSP430FR6887IPZR does not integrate dedicated AES or SHA hardware accelerators. It relies on software-based cryptographic libraries for security functions. However, its true random number seed generator supports secure key derivation, and the Memory Protection Unit (MPU) with IP encapsulation prevents unauthorized code access-providing foundational security for firmware integrity and data confidentiality in the MSP430FR6887IPZR platform.
What LCD configurations does the MSP430FR6887IPZR support?
The MSP430FR6887IPZR's LCD_C module supports static, 2-, 3-, 4-, 6-, and 8-mux configurations, driving up to 320 segments. It includes programmable charge pump, contrast control, and blinking capability-enabling direct interface to custom segment displays without external bias circuitry. This full LCD capability is confirmed in the MSP430FR6887IPZR datasheet Section 6.11 and distinguishes it from lower-tier variants like MSP430FR6877IPZR (240 segments).
Is the MSP430FR6887IPZR pin-compatible with other MSP430FR68xx devices?
Yes-the MSP430FR6887IPZR shares identical 100-pin LQFP (PZ) package and pinout with MSP430FR6879IPZR and MSP430FR6877IPZR. All three devices maintain consistent signal mapping for power, ground, JTAG/SBW, crystal, ADC, timers, eUSCI, and LCD pins. This allows direct PCB reuse across firmware variants, though functional differences (e.g., TA3 timer presence, LCD segment count) must be validated in software for the MSP430FR6887IPZR.
What is the FRAM endurance rating for the MSP430FR6887IPZR?
The MSP430FR6887IPZR features 128KB of FRAM rated for 10¹⁵ write cycles per word-orders of magnitude higher than flash-based MCUs. This endurance enables continuous logging of sensor data, firmware updates, and configuration changes without wear-out concerns. The specification is guaranteed across the full industrial temperature range (–40°C to 85°C) and is a defining characteristic of the MSP430FR6887IPZR FRAM architecture.
