Our RS08 microcontrollers (MCUs) with LCD drivers are highly integrated but extremely cost-effective. The MC9RS08LA8 and MC9RS08LE4 MCUs are intended for small appliances, medical equipment and other industrial and multi-market applications. The LA and LE families provide design flexibility with a large segment-based (8x mode) driver and an integrated charge pump to provide true system-on-chip (SoC) functionality.
