FAQ

What supply voltage does it support?

The device operates across a wide supply range from 1.8 V to 3.6 V, enabling use with single?cell lithium chemistries and standard 3.3 V rails without external regulators in many designs.

Which package is this part in?

This specific ordering code denotes a 28?lead TSSOP package (PW suffix). The compact TSSOP?28 footprint is suited for space?constrained PCB layouts and automated assembly.

How much program memory is available?

The MCU provides 2 KB of on?chip Flash program memory, sufficient for compact control firmware and typical sensor or HMI applications requiring modest code size.

Is there an on?chip ADC?

Yes. A 10?bit ADC is included to support analog sensing and measurement directly on the MCU, which reduces the need for external ADC components in mixed?signal systems.

What serial options are supported?

The device includes a universal serial interface (USI) that can implement UART, SPI?style, or I2C?style serial links, enabling flexible connection to sensors, peripherals, and host processors.
