On today’s computers, keyboards connect with the host most often via a wireless connection and offer a growing number of alternative text-input methods – including microphones – in addition to the classical key matrix.

We have a range of wireless connectivity and power management solutions as well as a wide selection of low-power microcontrollers, MEMS microphones and protection devices for the most demanding battery-operated keyboards.
