FAQ

What core does it use?

The device uses the MSP430 16-bit RISC core. That core prioritizes compact code and efficient instruction cycles, making it suitable for control loops and simple real-time processing tasks.

What is the operating voltage?

It operates from approximately 1.8 V up to about 3.6 V. This voltage range enables direct operation from common single-cell lithium or multi-cell alkaline arrangements with appropriate regulation.

Does it include an ADC?

Yes. The MCU integrates a 10-bit analog-to-digital converter, allowing designers to measure analog signals directly without a separate ADC, which reduces BOM cost and board area.

Is it rated for industrial temperatures?

Yes. The part carries an industrial temperature range of -40 ??C to +85 ??C, which supports deployment in outdoor, industrial and harsher ambient environments.

What package and pin count is available?

This part is supplied in a 20-pin package (PDIP style). The 20-pin footprint makes it simpler to route on small PCBs while retaining multiple I/O lines and peripheral access.
