Overview

The MSP430FR2355TRHAR is a highly integrated 16-bit RISC microcontroller featuring 32KB of unified Ferroelectric Random Access Memory (FRAM). It operates at up to 24MHz and is designed for ultra-low-power applications requiring frequent data logging and high endurance, with a shutdown current as low as 0.042uA. This device includes specialized analog peripherals such as four 12-bit DACs and a 10-channel 12-bit ADC.

Why Choose This Part

The primary advantage is the unified FRAM memory, which provides the speed of RAM with the non-volatility of Flash and significantly higher write endurance. The inclusion of four 12-bit DACs and a 24MHz clock allows for sophisticated signal generation and processing that typically requires external components or higher-tier microcontrollers.

Applications

Industrial Sensing and Data Logging
Utilizes 32KB of FRAM for high-speed, high-endurance non-volatile data storage with 10^15 write cycles, ideal for sensor nodes tracking frequent events.
Battery-Powered Portable Instruments
Takes advantage of the ultra-low 142uA/MHz active current and multiple sleep modes (LPM3/LPM4) to maximize battery life in handheld devices.
Small Form-Factor Control Systems
The 40-VQFN package provides 36 I/O pins and integrated 12-bit converters (ADC and DAC) for precise control in space-constrained designs.
