MSP430G2112IPW20 Key Features

• Ultra?low power core that lowers standby and active energy consumption to extend battery life in portable systems.
• 16?bit RISC architecture for efficient integer math and control tasks, reducing code size versus 32?bit alternatives.
• Integrated clock and timers to simplify timing, reduce external components and improve deterministic control.
• Compact 20?pin package for higher board density and lower cost compared with larger packages.

Typical Applications

• Battery?operated sensor nodes where years of standby time are required and minimal active current preserves battery capacity.
• Portable medical devices that need predictable timing, low sleep current and a small board footprint for wearable form factors.
• Industrial sensors and actuators where wide temperature range and robust low?power modes improve reliability and mean time between maintenance.
• Consumer handheld controls and remote interfaces that benefit from long battery life, basic analog monitoring and compact packaging.

MSP430G2112IPW20 Advantages vs Typical Alternatives

The device favors lower power and smaller size compared with many 8?bit and 32?bit alternatives. Its 16?bit core delivers more efficient control code and fewer clock cycles per operation than comparable 8?bit MCUs, yet consumes less energy than many 32?bit parts. The TSSOP?20 package reduces board area and BOM cost versus larger packages, while the on?chip timers and comparator reduce the need for external components. For designs prioritizing longer battery life and simpler hardware, this MCU offers a more efficient tradeoff.

FAQ

What is the supply voltage?

The device operates from 1.8 V to 3.6 V. This range supports common single?cell lithium and multi?cell alkaline configurations and helps designers choose power supplies that balance energy density and cost.

How many I/O pins are available?

The MCU provides up to 16 general?purpose I/O pins on the 20?pin package. Pins are typically multiplexed with on?chip peripherals, so check pin assignments for your chosen package and function set.

What low?power modes does it include?

Multiple low?power modes are available, including CPU off states and selectable clock gating to reduce active and standby current. These modes let applications trade wake latency for lower energy use.

Which peripherals are integrated?

On?chip peripherals include at least a timer, watchdog timer, comparator and a basic clock system. These reduce external component count for timing, reset supervision and simple analog threshold functions.

What package should I choose?

The TSSOP?20 package (20 pins) is the standard choice for compact PCBs. It offers a smaller footprint than DIP or larger SOIC packages while keeping manageable assembly requirements for volume production.
