Product details
Overview
MSP430FR5992IZVWR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller featuring 128KB + 0.5KB FRAM, 8KB RAM, integrated LEA accelerator, 12-bit ADC with 20 external channels, and dual crystal support (LFXT/HFXT). It operates from 1.8 V to 3.6 V and delivers 350 nA RTC-enabled standby (LPM3.5), targeting battery-powered sensing nodes in grid infrastructure and wearable electronics.
For engineers reviewing the MSP430FR5992IZVWR datasheet, MSP430FR5992IZVWR pinout, MSP430FR5992IZVWR application, or MSP430FR5992IZVWR equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), LEA-accelerated FFT performance, capacitive-touch I/O capability, and NFBGA-87 package compatibility with high-density PCB layouts.
Technical Context
The MSP430FR5992IZVWR implements a CPUXV2 core with 16 registers and integrates a dedicated Low-Energy Accelerator (LEA) subsystem sharing 4KB of RAM - enabling offload of 256-point complex FFTs without CPU intervention. Its clock system combines factory-trimmed DCO, LFXT (32 kHz), and HFXT (up to 24 MHz) for precise timing across active and low-power modes.
Peripherals include six 16-bit timers (TA0–TA4, TB0), four eUSCI_A (UART/IrDA/SPI) and four eUSCI_B (I²C/SPI) modules, AES-256 encryption coprocessor, and 16-channel analog comparator. All I/O pins support capacitive-touch sensing with no external components required.

Does the MSP430FR5992IZVWR support hardware-accelerated cryptography?
Yes, the MSP430FR5992IZVWR integrates a dedicated AES-256 security coprocessor that performs encryption and decryption independently of the CPU. This enables secure boot, authenticated firmware updates, and end-to-end encrypted sensor data transmission - all while preserving the MSP430FR5992IZVWR's ultra-low-power operation and deterministic latency.
How many capacitive-touch channels does the MSP430FR5992IZVWR support?
The MSP430FR5992IZVWR supports capacitive-touch sensing on all general-purpose I/O pins - totaling 68 pins across ports P1–P8 and PJ. No external components or dedicated touch controller ICs are required, and touch functionality is enabled via firmware configuration of the built-in charge-transfer circuitry within each port module of the MSP430FR5992IZVWR.
What crystal frequencies are compatible with the MSP430FR5992IZVWR's LFXT and HFXT inputs?
The MSP430FR5992IZVWR's LFXT input supports standard 32.768-kHz tuning-fork crystals for RTC operation, while the HFXT input accepts fundamental-mode crystals from 4 MHz to 24 MHz. Both interfaces include programmable drive strength and fault-detection circuitry, ensuring robust oscillation startup and stability across temperature and voltage ranges specified for the MSP430FR5992IZVWR.
Is the MSP430FR5992IZVWR pin-compatible with other devices in the MSP430FR599x family?
Yes - the MSP430FR5992IZVWR in the NFBGA-87 (ZVW) package shares identical pinout, ball mapping, and electrical characteristics with MSP430FR5994IZVWR, MSP430FR5962IZVWR, and MSP430FR5964IZVWR in the same ZVW package.
