Overview

The MSP430G2553IPW28 is a low-power 16-bit RISC microcontroller designed for battery-operated sensing and measurement applications. It features 16KB of Flash, 512 bytes of RAM, and a high-performance 10-bit ADC capable of 200-ksps sampling. This specific variant comes in a 28-pin TSSOP package, providing 24 I/O pins for expanded peripheral connectivity.

Why Choose This Part

The device excels in power efficiency, consuming as little as 0.23mA at 1MHz while offering five distinct power-saving modes. It integrates high-value analog peripherals, including a 10-bit ADC with internal reference and a comparator for signal conditioning, reducing overall BOM cost and PCB footprint.

Applications

Battery-Powered Remote Sensors
Ideal for environmental monitors and wireless sensor nodes requiring ultra-low sleep current and fast wake-up (under 1 microsecond).
Capacitive Touch Interfaces
Utilizes dedicated capacitive-touch enabled I/O pins to implement buttons, sliders, and wheels without external active components.
Handheld Medical Devices
Well-suited for pulse oximeters and glucose meters that benefit from the integrated 10-bit ADC and low-power standby modes.
