FAQ

What supply voltages are supported?

The device operates across a low voltage range of 1.8 V to 3.6 V. This supports single?cell lithium and common 3.3 V systems while enabling reduced power consumption in battery designs.

What package and pin count are available?

This part is supplied in a 20?pin PDIP package. The 20 pins include power, ground, multiple GPIO lines, and peripheral pins suitable for through?hole prototyping and legacy board layouts.

What analog capability does it include?

The MCU integrates a 10?bit ADC with multiple channels. This lets designers sample sensors directly without adding an external ADC, saving board space and cost.

Is it suitable for industrial environments?

Yes. The industrial temperature rating spans ?40 ??C to +85 ??C. That range supports outdoor, automotive?adjacent, and factory floor deployments where temperature extremes occur.

How does it compare to 8?bit MCUs?

With a 16?bit core, the device processes 16?bit math more efficiently and often reduces code size for control algorithms versus many 8?bit parts. It also offers integrated analog and timer resources at a similar cost point.
