FAQ

What is the package type?

The device is supplied in a 14?lead TSSOP package (commonly identified by the PW suffix), which is suitable for space?constrained PCBs while remaining compatible with standard assembly and reflow processes.

What voltage range does it support?

It supports a nominal operating voltage range from 1.8 V up to 3.6 V, allowing direct operation from typical single?cell batteries and standard low?voltage power rails without additional regulators.

Does it include analog inputs?

Yes. The MCU includes a 10?bit ADC (ADC10) for analog measurements, enabling digital conversion of sensor signals without large external ADC components, which reduces BOM and board area.

Which serial interfaces are available?

The device implements a USI (Universal Serial Interface) that can be configured for SPI or I2C operation, providing flexible communication options for peripheral sensors and external memory.

Is the MCU suitable for harsh temperatures?

It is specified for operation from -40 ??C to +85 ??C, making it appropriate for industrial and field environments that require reliable performance across wide temperature ranges.
