Overview

The MSP430FR2311IPW16R is an ultra-low-power 16-bit RISC microcontroller from Texas Instruments featuring 3.75KB of Ferroelectric RAM (FRAM). This unified memory technology combines the speed and endurance of RAM with the non-volatility of Flash, making it ideal for data-logging and energy-constrained applications. It operates at up to 16MHz and includes a 10-bit ADC and specialized IR modulation logic.

Why Choose This Part

The primary advantage is the 3.75KB of FRAM, which offers 10 to the 15th power write cycle endurance and significantly lower power consumption during writes compared to traditional Flash. It features a highly efficient power profile with active mode current as low as 0.126mA/MHz and a shutdown current of 0.032 uA. The 16-TSSOP package provides a compact footprint with 11 I/O pins and an integrated 10-bit ADC for mixed-signal processing.

Applications

Battery-Powered Remote Sensors
Utilizes extremely low standby currents (0.71 uA) and fast wake-up times to extend battery life in wireless sensor nodes.
Energy Harvesting Systems
The low-power consumption and fast FRAM write speeds allow the device to capture and store data during brief power bursts from harvested sources.
Portable Medical Devices
Suitable for compact, low-power health monitors where high-endurance memory is required for frequent parameter logging.
Infrared Remote Controls
Integrated IR modulation logic simplifies the design of consumer electronics control interfaces.

Getting Started

Developers can begin evaluation using the MSP-EXP430FR2311 LaunchPad development kit. Code development is supported in Code Composer Studio (CCS) and IAR Embedded Workbench, utilizing the MSP430Ware software library for driver abstraction. Programming and debugging are typically handled via the MSP-FET Flash Emulation Tool or the onboard debugger of a LaunchPad.
