• Multiple low-power modes that deliver significantly lower standby current than many mid-range MCUs, optimizing energy efficiency for always-on and battery-backed systems.
• Single 16-bit Timer_A provides PWM and capture/compare functions for motor control, dimming, and precise timing compared to software timers.

Typical Applications

• Battery-powered sensor node with multi-year life expectancy using low-power modes and a 10-bit ADC for analog sensor measurement and local processing.
• Portable handheld instrument that needs accurate ADC readings, compact 20-pin layout, and single-supply 1.8?C3.6 V operation for simpler power design.
• Industrial control interface requiring deterministic 16-bit processing, a Timer_A for PWM control, and a reliable USI link to communicate with larger host systems.
• Consumer product with cost and space constraints that benefits from integrated serial peripherals and low standby current to extend battery runtime.

MSP430G2252IPW20 Advantages vs Typical Alternatives

The device offers a compact 20-pin PDIP option with a full 16-bit core, which delivers better arithmetic performance and lower code density than many 8-bit competitors. It supports up to 16 MHz operation and a built-in 10-bit ADC, reducing the need for external converters and lowering BOM cost. Its 1.8?C3.6 V range and five low-power modes yield longer battery life compared with mid-range MCUs that lack multiple sleep levels. The integrated USI provides flexible serial options without dedicating multiple peripheral ICs.
