Overview

The MSP430FR4133IG56R is a 16-bit RISC microcontroller featuring 15.5KB of Ferroelectric Random Access Memory (FRAM), a non-volatile memory technology that combines the speed of RAM with the persistence of Flash. Designed for ultra-low-power sensing and measurement, it includes an integrated LCD controller capable of driving up to 256 segments and a 10-bit ADC. Its 16MHz clock speed and high-endurance FRAM make it ideal for data logging applications where frequent, fast memory writes are required.

Why Choose This Part

The primary advantage is the unified FRAM architecture, which allows for extremely fast writes and near-infinite endurance compared to traditional Flash memory. The device also excels in power efficiency, consuming only 126uA/MHz in active mode and featuring a shutdown current of just 0.015uA. Its high I/O count of 52 pins in a TSSOP package provides significant connectivity for a small-scale microcontroller.

Applications

Battery-Powered Water Meters
Utilizes the integrated LCD driver and low standby current of 1.2uA to maintain long-term operation on a single cell.
Digital Thermostats
Leverages the 10-bit ADC for sensor interfacing and the flexible LCD controller for user interface display.
Portable Data Loggers
Takes advantage of 10^15 write cycle endurance in FRAM to log high-frequency sensor data without wearing out the memory.
Remote Industrial Sensors
Uses the built-in IR modulation logic and low-power modes to transmit status data over optical links in energy-constrained environments.
