Product details
Overview
MSP430FR5992IPNR 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 supports LPM4.5 shutdown mode at 45 nA - ideal for battery-powered grid infrastructure and wearable fitness monitors.
For engineers reviewing the MSP430FR5992IPNR datasheet, MSP430FR5992IPNR pinout, MSP430FR5992IPNR application, or MSP430FR5992IPNR equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), LEA-accelerated FFT performance, RTC calendar support in LPM3.5, and UART/I²C bootloader compatibility across 80-pin LQFP packages.
Technical Context
The MSP430FR5992IPNR implements a CPUXV2 16-bit RISC core with up to 16 MHz operation and integrates a dedicated Low-Energy Accelerator (LEA) subsystem sharing 4KB of RAM - enabling standalone execution of complex signal processing (e.g., 256-point complex FFT) without CPU intervention. Its memory architecture unifies code and data storage in nonvolatile FRAM with 125 ns per-word write speed.
Power management includes five low-power modes (LPM0–LPM4.5), with LPM3.5 sustaining real-time clock operation using a 3.7-pF crystal at 350 nA, and LPM4.5 delivering 45 nA shutdown current. Clock sources comprise DCO (10 factory-trimmed frequencies), LFXT (32 kHz crystal), HFXT (high-frequency crystal), and VLO.

FAQ
What is the maximum operating frequency of the MSP430FR5992IPNR?
The MSP430FR5992IPNR supports a maximum system clock frequency of 16 MHz via its digitally controlled oscillator (DCO) or external HFXT crystal. This frequency is fully supported across all active and low-power modes where CPU operation is enabled, and timing-critical peripherals like timers and ADC maintain specification compliance at this rate. The MSP430FR5992IPNR achieves deterministic real-time response without dynamic voltage scaling penalties.
Does the MSP430FR5992IPNR include hardware encryption capabilities?
Yes, the MSP430FR5992IPNR integrates a dedicated 128/256-bit AES security coprocessor and memory protection unit (MPU) with IP encapsulation. These features enable secure boot, encrypted firmware updates, and protected data storage - critical for applications such as smart grid meters and building controllers where firmware integrity and sensor data confidentiality are mandated by standards like IEC 62056 and ISO/IEC 14443.
How many I/O pins does the MSP430FR5992IPNR support, and what special functions do they offer?
The MSP430FR5992IPNR provides 68 general-purpose I/O pins in its 80-pin LQFP package. Every pin supports capacitive-touch sensing without external components, configurable pullup/pulldown, edge-selectable wake-from-LPM, and bit/byte/word access. Dedicated functions include six eUSCI_A (UART/IrDA/SPI) and four eUSCI_B (I²C/SPI) modules, plus timer capture/compare, ADC inputs, and comparator channels mapped across multiple ports.
What low-power modes are available on the MSP430FR5992IPNR, and what are their typical currents?
The MSP430FR5992IPNR offers five low-power modes: LPM0 (118 µA/MHz active-equivalent), LPM3 with VLO (500 nA), LPM3.5 with RTC (350 nA using 3.7-pF crystal), and LPM4.5 shutdown (45 nA). These values are measured under specified conditions (VCC = 3.0 V, TA = 25°C) and reflect actual silicon characterization - enabling precise battery-life estimation for applications ranging from daily-wear trackers to decade-deployed utility sensors.
Is the MSP430FR5992IPNR pin-compatible with other devices in the MSP430FR59xx family?
Yes, the MSP430FR5992IPNR in the 80-pin LQFP (PN) package shares identical pinout, electrical characteristics, and peripheral mapping with MSP430FR5994IPN, MSP430FR5962IPN, and MSP430FR5964IPN. This allows direct substitution within the same PCB footprint when memory or LEA requirements change - provided software is updated to match FRAM size and accelerator enablement.
