Typical Applications

• Battery-powered measurement modules requiring long standby time and compact sensor interface, where low supply current extends service intervals.
• Industrial process controllers that need deterministic timing, integrated analog inputs, and robust operation across -40 ??C to +85 ??C environments.
• Portable instrumentation that consolidates MCU, ADC, and timers to reduce PCB area and lower BOM cost while maintaining measurement accuracy.
• Motor control and power-management front ends where multiple 16-bit timers and efficient code execution provide finer control and faster response.

MSP430F155IPMR Advantages vs Typical Alternatives

The part offers a focused balance of low power and integrated analog/digital peripherals compared with many 8-bit MCUs and higher-power 32-bit options. Its 16-bit core gives better arithmetic efficiency than typical 8-bit controllers, while the low-voltage range and sleep modes reduce system energy use versus many general-purpose MCUs. The TSSOP-28 package and on-chip ADC/timers lower external BOM and board area compared to separate MCU plus ADC solutions.
