Overview

The MSP430F5438AIPZR is a high-performance 16-bit RISC microcontroller designed for ultra-low-power sensing and measurement applications. It features a large 256KB Flash memory and 16KB RAM, operating up to 25MHz with a highly flexible clock system and an integrated LDO for core voltage regulation. This device is optimized for battery-powered instruments requiring a high pin count and integrated 12-bit analog-to-digital conversion.

Why Choose This Part

This MCU offers an impressive 87 I/O pins in a 100-LQFP package, providing extensive connectivity for complex systems. Its sophisticated power management system includes a shutdown mode (LPM4.5) drawing only 0.1uA, while the integrated 3-channel DMA and hardware multiplier offload the core for high-efficiency processing.

Applications

Industrial Handheld Meters
Ideal for portable gas detectors or multi-meters that require 12-bit ADC accuracy and extended battery life through low-power modes.
Energy Management Systems
Utilizes the hardware multiplier and multiple serial interfaces (UART, SPI, I2C) to monitor and communicate power consumption data.
Data Logging
The 256KB Flash and DMA controller allow for efficient handling and storage of sensor data with minimal CPU intervention.
Wireless Sensor Nodes
The ultra-low standby current of 1.7uA and fast wake-up times make it suitable for periodic RF transmission tasks.
