• Compact 16?pin package ?? tight PCB footprint compared to larger MCU packages for space?constrained designs.

Typical Applications

• Battery?powered sensor nodes for environmental monitoring that require low standby current and periodic ADC sampling for longer field life.
• Metering and handheld instruments that need precise timer control and a small memory footprint to handle measurement routines.
• Simple industrial controls and status monitors where compact 16?pin packages and industrial temperature range are required.
• Consumer devices such as compact remotes, wearables or toy control boards where cost, size and multi?mode power savings are priorities.

MSP430G2131IRSA16T Advantages vs Typical Alternatives

This device combines a 16?bit CPU with energy frugal operation, offering more computation per cycle than many 8?bit controllers while consuming far less power than larger 32?bit MCUs. It uses fewer external components thanks to built?in ADC and timers. In a 16?pin package it delivers more analog and timing features than comparable tiny MCUs, so designers can save PCB area, reduce BOM costs, and improve battery run time without sacrificing essential peripheral functions.
