Product details
Overview
MSP430FR5992IPMR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 128KB+0.5KB FRAM, 8KB RAM, integrated LEA accelerator, 12-bit ADC (20 external channels), and 16-channel analog comparator. It operates from 1.8 V to 3.6 V and delivers 118 µA/MHz active current, 350 nA RTC-enabled standby (LPM3.5), and 45 nA shutdown (LPM4.5), targeting battery-powered sensing and metering systems.
For engineers reviewing the MSP430FR5992IPMR datasheet, MSP430FR5992IPMR pinout, MSP430FR5992IPMR application, or MSP430FR5992IPMR equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), LEA-accelerated FFT performance, capacitive-touch I/O support, UART/I²C eUSCI peripherals, and LQFP-64 package compatibility with industrial PCB layouts.
Technical Context
The MSP430FR5992IPMR implements a CPUXV2 16-bit RISC core with up to 16 MHz clock, paired with a dedicated Low-Energy Accelerator (LEA) subsystem sharing 4KB of RAM. The LEA executes signal-processing kernels-such as 256-point complex FFT-without CPU intervention, achieving up to 40× speedup over Cortex-M0+ for sensor data preprocessing.
Its mixed-signal architecture integrates six 16-bit timers (including Timer_A with 3/3 capture/compare registers and Timer_B with 2/2/2), dual crystal oscillators (LFXT/HFXT), and a flexible clock system with DCO trimming. All I/O pins support capacitive-touch sensing without external components, and memory protection includes MPU with IP encapsulation and 128/256-bit AES encryption.

FAQ
What is the maximum operating frequency of the MSP430FR5992IPMR?
The MSP430FR5992IPMR supports a maximum CPU clock frequency of 16 MHz, enabled by its factory-trimmed DCO oscillator or external HFXT crystal. This frequency is fully supported across the entire 1.8 V–3.6 V supply range and all active power modes, allowing deterministic real-time execution for time-critical sensor sampling and control loops.
Does the MSP430FR5992IPMR include hardware encryption capabilities?
Yes, the MSP430FR5992IPMR integrates a dedicated 128/256-bit AES security coprocessor with random number seed generation. This enables accelerated encryption/decryption of firmware images, secure communication payloads, and stored sensor data - all without burdening the main CPU, preserving low-power operation during security operations.
How many eUSCI modules does the MSP430FR5992IPMR support, and what protocols do they implement?
The MSP430FR5992IPMR includes four eUSCI_A modules (UART/IrDA/SPI) and four eUSCI_B modules (I²C/SPI). Each eUSCI_A supports automatic baud-rate detection and IrDA encoding; each eUSCI_B supports multi-slave I²C addressing - enabling concurrent communication with BLE modules, environmental sensors, and display controllers.
What is the role of the Low-Energy Accelerator (LEA) in the MSP430FR5992IPMR?
The LEA in the MSP430FR5992IPMR is a standalone signal-processing subsystem that executes FFT, FIR, and matrix operations in hardware while the CPU remains in low-power mode. It shares 4KB of RAM with the CPU and delivers up to 40× faster 256-point complex FFT than a Cortex-M0+, reducing active processing time and extending battery life in sensor analytics applications.
Is the MSP430FR5992IPMR pin-compatible with other devices in the MSP430FR59xx family?
Yes, the MSP430FR5992IPMR in the LQFP-64 (PM) package shares identical pinout, electrical characteristics, and peripheral mapping with MSP430FR5962IPMR and MSP430FR5994IPMR - enabling drop-in replacement within the same package variant for memory or feature scaling without PCB redesign.
