FAQ

What is the supply voltage?

The device operates across a 1.8?C3.6 V supply range. This allows direct connection to common single-cell lithium or multiple alkaline cells while keeping low-power operation.

Does it include an ADC?

Yes. The MCU integrates a 10-bit analog-to-digital converter with multiple input channels. This enables on-chip sensor sampling without an external ADC for many designs.

How many GPIOs are available?

It provides up to 16 general-purpose I/O pins. Pin count and available peripherals vary by package, so check the package pinout for exact signal assignments.

What low-power features exist?

Multiple low-power modes are supported, including deep-sleep states with sub-microamp standby current. These modes cut active power while preserving key registers for quick resume.

Which interfaces does it support?

The part includes a USI for serial communication, Timer_A for PWM and timing, and an ADC. These integrated peripherals reduce the need for external interface chips in many applications.
