Product details

Overview

MSP430FR6987IPZR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 64KB FRAM, 2KB RAM, integrated LCD driver (up to 320 segments), 12-bit ADC with 16 external inputs, and Extended Scan Interface (ESI) for precision metering. It operates from 1.8 V to 3.6 V and supports real-time clock (RTC) operation at 0.35 µA in LPM3.5 mode - optimized for battery-powered utility meters.

For engineers reviewing the MSP430FR6987IPZR datasheet, MSP430FR6987IPZR pinout, MSP430FR6987IPZR application, or MSP430FR6987IPZR equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), ESI-based capacitive sensing for fluid/gas measurement, AES256 encryption, and dual eUSCI modules supporting UART/IrDA/SPI/I²C with hardware bootloader.

Technical Context

The MSP430FR6987IPZR implements the ULP CPUXV2 core with seven low-power modes, including LPM3.5 (RTC active) and LPM4.5 (shutdown at 0.02 µA). Its FRAM memory architecture enables fast, low-energy writes (125 ns/word) and unified program/data/storage space without erase cycles.

It integrates a dedicated Extended Scan Interface (ESI) with programmable gain amplifiers and sigma-delta modulators for high-precision, low-noise background measurement of water, heat, and gas volumes - independent of CPU activity. The ESI subsystem includes dedicated analog front-end channels (ESICH0–ESICH3, ESICI0–ESICI3) and digital verification logic.

Key Specifications

Parameter	Value and Actual Design Meaning
Core Architecture	16-bit RISC CPUXV2, up to 16-MHz operation - enables deterministic real-time control with minimal power overhead.
Nonvolatile Memory	64KB ferroelectric RAM (FRAM) - retains data without power, supports 10¹⁵ write cycles, no erase required before write.
RAM	2KB SRAM - used for stack, variables, and high-speed buffering; separate from FRAM for performance isolation.
ADC	12-bit SAR ADC with internal reference and sample-and-hold, up to 16 external inputs - supports precision sensor digitization in metering applications.
ESI Channels	4-channel extended scan interface (ESICH0–ESICH3) with dedicated analog inputs and digital post-processing - enables simultaneous multi-parameter metrology without CPU intervention.
Low-Power RTC	Real-time clock in LPM3.5 draws 0.35 µA (typical) - maintains calendar/timekeeping while system remains in ultra-deep sleep.
Security	AES256 encryption/decryption coprocessor with true random number seed - provides hardware-accelerated secure firmware updates and data protection.

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultra-low-power metrology microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MSP430FR6989IPZR	128KB FRAM, identical package and pinout, adds two extra TA0 capture/compare registers and full 16-channel ADC support.	Required when >64KB FRAM needed for extended firmware features or larger data buffers; supports additional analog inputs for multi-sensor nodes.	Select MSP430FR6989IPZR if future firmware expansion or higher channel count is anticipated; pin-compatible upgrade path.
MSP430FR5987IPM	64KB FRAM, 64-pin LQFP (10 mm × 10 mm), no LCD driver or ESI - lacks COM/segment outputs and metrology-specific analog front-end.	Suitable for compact sensor nodes where display and high-precision fluid/heat measurement are not required.	Choose MSP430FR5987IPM only for space-constrained designs omitting LCD and ESI; not functionally equivalent for metering use cases.

Compared with MSP430FR6987IPZR, the MSP430FR6989IPZR offers scalable FRAM and identical metrology peripherals in the same LQFP-100 package, while the MSP430FR5987IPM sacrifices ESI, LCD, and package size for reduced footprint - making it unsuitable as a drop-in replacement in utility meter designs.
