Makes ultra-low-power microcontroller and SoC chips for wearables and edge-AI devices using its own low-voltage technology.
Makes ultra-low-power microcontroller and SoC chips for wearables and edge-AI devices using its own low-voltage technology.
Designs its low-power chips but has outside foundries make them (fabless), then sells them to makers of watches, bands and other wearables, where a chip designed into a product generation is bought for that product's whole run. A small number of big device makers account for much of its sales, so a lost or won design matters.
Moat: narrow (IP / patents, process know-how). Proprietary sub-threshold voltage technology gives a claimed power-efficiency edge over rivals.
