Product details
Overview
MSP430FR5957IRHAT from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 32KB nonvolatile memory, 1KB RAM, and integrated peripherals including 12-bit ADC (14 external channels), RTC with calendar/alarm, five 16-bit timers, AES256 encryption coprocessor, and dual eUSCI modules supporting UART, SPI, and I²C. It operates from 1.8 V to 3.6 V and targets energy-constrained sensor nodes and metering systems.
For engineers reviewing the MSP430FR5957IRHAT datasheet, MSP430FR5957IRHAT pinout, MSP430FR5957IRHAT application, or MSP430FR5957IRHAT equivalent, key selection criteria include HFXT oscillator support (not LFXT), 40-pin VQFN (RHA) package, real-time clock operation at 0.25 µA in LPM3.5, FRAM endurance of 10¹⁵ write cycles, and capacitive touch I/O capability on all pins without external components.
Technical Context
The MSP430FR5957IRHAT implements the CPUXV2 core with 16 general-purpose registers and executes instructions at up to 16 MHz using a factory-trimmed DCO or external HFXT (4–24 MHz). Its low-power architecture supports seven operating modes, including LPM3.5 (RTC active, 0.25 µA typical) and LPM4.5 (shutdown, 0.02 µA typical), enabled by SVS brownout protection and programmable pullup/pulldown on all I/O ports.
Peripherals are tightly coupled via a unified bus: the 3-channel DMA controller offloads CPU during ADC conversions or FRAM transfers; the 16-bit CRC module accelerates firmware integrity checks; and the hardware MPY32 multiplier enables efficient signal processing. The device lacks LFXT pins (LFXIN/LFXOUT) but includes HFXIN/HFXOUT for high-frequency crystal support, distinguishing it from LFXT-only variants like MSP430FR594x.
