MSP430F1101AIPWR Key Features

• Single 16?bit CPU core that delivers compact code density and faster integer math compared with 8?bit alternatives.
• Low operating voltage (1.8?C3.6 V), enabling longer battery run time in portable and remote sensing applications.
• Integrated 10?bit ADC and Timer_A for direct sensor interfacing and precise event timing without external components.
• Universal Serial Interface (USI) for flexible serial connectivity, simplifying integration with SPI, I2C, or UART?like protocols.
• TSSOP?20 package reduces board area and BOM complexity versus larger packages while easing thermal management.
• Industrial temperature rating (?40 ??C to +85 ??C) for reliable operation in harsher environments compared to consumer?grade parts.

Typical Applications

• Battery?powered sensor nodes where ultra?low?power standby and compact package extend field life and reduce enclosure size.
• Portable instrumentation that needs a small 16?bit MCU with integrated ADC and timers to reduce external circuitry and costs.
• Simple motor or actuator controllers requiring deterministic 16?bit timing, low supply current, and minimal board area for embedded designs.
• Industrial I/O modules where industrial temperature range, small form factor, and standard serial interfaces ease integration into larger systems.

MSP430F1101AIPWR Advantages vs Typical Alternatives

The device offers a combination of 16?bit processing and sub?microamp standby that typically beats many 8?bit MCUs on throughput per watt. With integrated ADC and Timer_A, it reduces external components by 1?C3 parts in common sensor systems. Its 20?pin TSSOP package is 30?C50% smaller than many DIP or SOIC alternatives, improving PCB density. The industrial temperature rating and 1.8?C3.6 V operation make it more reliable across voltage and thermal ranges, while the USI adds flexibility compared with fixed?role serial modules.
