MSP430G2202IPW20 Key Features

• 16?bit RISC core ?? delivers compact code and faster arithmetic for control algorithms compared with 8?bit alternatives.
• Low supply range (1.8?C3.6 V) ?? allows direct operation from single?cell lithium or standard 3.3 V logic, simplifying power design.
• Ultra?low active and standby currents ?? reduces battery drain and extends service life in portable and remote applications.
• Integrated 16?bit Timer_A and USI ?? provides precise timing, event capture, and flexible serial links without extra components.
• Small 20?pin package ?? cuts PCB area and BOM cost versus larger MCUs while preserving necessary I/O and peripherals.

Typical Applications

• Battery?powered sensors and data loggers where minimal sleep current and a small footprint extend field life and reduce enclosure size.
• Simple industrial control nodes needing deterministic timing, basic serial connectivity, and low power in a low?cost package.
• Consumer peripherals and interfaces that require UART/SPI/I2C communication with a host MCU or sensor, while minimizing board area and cost.
• Portable measurement instruments and handheld meters where a 16?bit MCU yields better numeric resolution and lower power than equivalent 8?bit parts.

MSP430G2202IPW20 Advantages vs Typical Alternatives

The device combines a 16?bit instruction set with lower power draw and fewer pins than many 28?pin microcontrollers. It often replaces larger MCUs where only one timer and a single serial interface are required, reducing BOM and board area. Compared with typical 8?bit alternatives, the 16?bit core executes arithmetic and control code in fewer cycles. The 1.8?C3.6 V supply window also makes it more flexible for single?cell and mixed?voltage systems.
