MSP430I2041TPW Technical Specifications

MSP430I2041TPW Key Features

• One 16-bit RISC core for compact code and efficient control loops with predictable timing.
• Low-voltage operation (1.8?C3.6 V) enables simple single-cell battery systems and reduced power rails.
• Minimal non-volatile memory and SRAM balance cost and footprint for control tasks that need reliability.
• On-chip timers and serial interfaces reduce external component count and simplify PCB layout for denser designs.

Typical Applications

• Battery-powered sensor nodes where the MCU must balance active processing and deep sleep to extend battery life beyond months or years.
• Simple industrial control panels requiring deterministic timing, basic serial connectivity, and stable operation over -40 ??C to +85 ??C.
• Appliance control functions where a small code footprint and low active current provide cost-effective control of motors or valves.
• Portable instrumentation that needs sub-mA active consumption, a compact package, and basic timing peripherals for measurement tasks.

MSP430I2041TPW Advantages vs Typical Alternatives

This device offers a smaller memory footprint and lower active currents compared with many 8/32-bit alternatives, making it more power- and cost-efficient for basic control tasks. The 16-bit core delivers more compact and faster arithmetic than 8-bit designs, while simpler peripherals reduce BOM and board area versus larger 32-bit MCU families. Use this part where power, size, and cost matter most.
