FAQ

What is the supply voltage range?

The device operates from 1.8 V to 3.6 V. This range supports single-cell lithium and many low-voltage battery chemistries and keeps dynamic power consumption low under typical loads.

Which package and pin count apply?

This part is offered in a 28-pin TSSOP package. The small TSSOP package reduces PCB area compared with larger through-hole or wide-body surface-mount packages.

What debug interfaces are supported?

Programming and debug are supported via Spy-Bi-Wire and standard JTAG-compatible interfaces, enabling single- or two-wire connections for development and in-system programming.

Does it support low-power modes?

Yes. The microcontroller implements several sleep and standby states (multiple LPM levels). These states let designers minimize current draw between active cycles for battery-operated products.

What on-chip peripherals help reduce BOM?

The MCU includes an integrated Timer_A module and a USI serial interface. These on-chip peripherals eliminate some external timers and serial converters, simplifying designs and reducing cost.
