Product details
Overview
MSP430FR6989IPNR from Texas Instruments is an ultra-low-power mixed-signal microcontroller featuring 128KB FRAM, 2KB SRAM, and a 16-bit RISC CPUX core. It integrates a 12-bit ADC, AES-128 accelerator, real-time clock (RTC), LCD controller, and multiple low-energy peripherals. Designed for battery-powered metering and sensing applications requiring long-term data retention and frequent write cycles.
For engineers reviewing the MSP430FR6989IPNR datasheet, MSP430FR6989IPNR pinout, MSP430FR6989IPNR application, or MSP430FR6989IPNR equivalent, key selection criteria include FRAM endurance (1015 write cycles), LPM3.5/LPM4.5 sub-μA sleep current, integrated LCD driver support for up to 320 segments, and hardware AES acceleration for secure firmware updates.
Technical Context
The MSP430FR6989IPNR implements a segmented memory architecture with unified FRAM addressing, enabling code execution directly from nonvolatile memory without flash wait states. Its FRAM controller supports ECC protection, automatic write-back caching, and configurable wait-state control across operating voltage ranges (1.8–3.6 V).
Low-power operation is enforced via hierarchical clock gating, programmable voltage-core scaling (VCORE), and dual low-power modes-LPM3.5 retains RTC and RAM with 100 nA typical current, while LPM4.5 powers down all domains except the reset circuit, drawing 20 nA typical.

FAQ
What is the maximum operating frequency of the MSP430FR6989IPNR?
The MSP430FR6989IPNR supports a maximum system clock frequency of 16 MHz, achievable using the integrated digitally controlled oscillator (DCO) or external HFXT crystal up to 24 MHz. The CPUX core executes instructions at this rate with zero wait states when running from FRAM, enabling deterministic real-time response in metrology and control loops.
Does the MSP430FR6989IPNR support hardware-based cryptographic operations?
Yes, the MSP430FR6989IPNR includes a dedicated AES-128 accelerator with DMA integration and key storage in protected memory. It supports ECB, CBC, and CCM modes, enabling secure firmware updates and encrypted sensor data transmission without burdening the CPU-critical for compliance with IEC 62443 and UL cybersecurity requirements.
How does the FRAM memory in MSP430FR6989IPNR differ from traditional flash in terms of endurance and write speed?
The MSP430FR6989IPNR's 128KB FRAM offers 1015 write/erase cycles-orders of magnitude higher than flash-and writes data in ~100 ns per word with no erase prerequisite. This eliminates wear leveling overhead and enables reliable, high-frequency logging (e.g., every 10 ms) in utility meters without memory degradation over 20+ years.
Can the MSP430FR6989IPNR drive an LCD display without external components?
Yes, the MSP430FR6989IPNR integrates a programmable segment LCD controller supporting up to 320 segments (4×80 or 8×40 mux). It provides internal charge pumps, bias generation, and contrast control-enabling direct connection to glass LCDs without external drivers, resistors, or capacitors in most standard configurations.
What low-power modes are supported by the MSP430FR6989IPNR, and what is the typical current draw in LPM4.5?
The MSP430FR6989IPNR supports seven low-power modes including LPM3.5 (100 nA typical, RTC + RAM active) and LPM4.5 (20 nA typical, full power-down except reset logic). In LPM4.5, all clocks, peripherals, and memory are disabled-only the RST/NMI pin and internal reset circuit remain active, enabling ultra-long battery life in intermittent wake-up applications.
