MSP430FR5994IPN 16-bit FRAM Microcontroller (IPN Package)

MSP430FR5994IPN Overview

The MSP430FR5994IPN is a low-power, 16?bit microcontroller built around the MSP430 CPU and nonvolatile FRAM memory. It combines fast write FRAM with integrated analog and digital peripherals to support battery-powered and industrial control systems that need more memory and lower dynamic power than many flash-based alternatives. The device targets system designs that require low energy operation, flexible serial interfaces, and deterministic interrupt response. See full sourcing and ordering details from IC Manufacturer.

MSP430FR5994IPN Technical Specifications

MSP430FR5994IPN Key Features

• Single 16?bit MSP430 core with deterministic interrupt latency for precise control and timing.
• Large 256 KB FRAM for fast, high?endurance nonvolatile data storage that reduces write latency and system complexity.
