Product details
Overview
MSP430FR5988IRGCR from Texas Instruments is an ultra-low-power 16-bit FRAM microcontroller with 96KB nonvolatile memory, 2KB RAM, integrated 12-bit ADC (12 external inputs), RTC with calendar, and Extended Scan Interface (ESI) for metering applications. It operates from 1.8 V to 3.6 V and supports LPM3.5 mode at 0.35 µA for battery-powered utility meters.
For engineers reviewing the MSP430FR5988IRGCR datasheet, MSP430FR5988IRGCR pinout, MSP430FR5988IRGCR application, or MSP430FR5988IRGCR equivalent, key selection criteria include FRAM endurance (1015 writes), ESI peripheral for capacitive sensing in water/heat meters, AES256 encryption, and VQFN-64 package compatibility with space-constrained industrial designs.
Technical Context
The MSP430FR5988IRGCR implements a 16-bit CPUXV2 core with seven low-power modes, including LPM3.5 (RTC active, 0.35 µA) and LPM4.5 (shutdown, 0.02 µA). Its FRAM architecture enables byte-level writes without erase cycles and eliminates flash wear-out limitations.
It integrates dual eUSCI modules (eUSCI_A0/A1 supporting UART/IrDA/SPI; eUSCI_B0/B1 supporting I²C/SPI), three-channel DMA, 32-bit hardware multiplier, and CRC16/CRC32 engines - all optimized for deterministic real-time operation in energy-harvested or long-life battery systems.
