MSP430G2001IRSA16R Key Features

• Single 16-bit core ?? offers deterministic instruction timing and compact code density compared with 8-bit alternatives.
• Ultra-low-power operation ?? reduces battery drain and extends runtime in portable and always-on systems.
• Small Flash and RAM footprint ?? enables cost-effective integration in simple control applications while preserving essential functionality.
• Compact 16-pin package ?? supports denser board layouts and simpler BOMs versus larger MCUs with similar capabilities.

Typical Applications

• Battery-powered sensor nodes requiring multi-year battery life, simple data processing, and periodic wake-up for measurements and transmission.
• Low-cost consumer controls such as touch or button interfaces where compact hardware and low standby current reduce system cost.
• Industrial monitoring endpoints that need robust operation across -40 ??C to +85 ??C and deterministic control with small code size.
• Power-management controllers for LED drivers, power switches, or simple DC/DC regulation that benefit from low quiescent current and compact packages.

MSP430G2001IRSA16R Advantages vs Typical Alternatives

The device balances size, power, and cost. It consumes far less active and standby current than many 8-bit microcontrollers with similar peripheral counts. Its 16-bit core gives denser code and fewer instructions for arithmetic and control tasks compared with 8-bit designs. The 16-pin footprint and small memory sizes reduce PCB area and BOM cost versus larger general-purpose MCUs. For simple sensing and control jobs, it offers a tighter fit in terms of power, price, and package than more feature-rich parts that add unnecessary peripherals.
