The MC9S08LG family of 8-bit microcontrollers drives liquid crystal displays (LCD) with up to 296 segments. The 5-volt segment LCD MCUs LG32 and LG16 offer improved performance and flexible pin functionality for a wide range of industrial and automotive applications, such as electric metering, home appliances, HVAC systems and entry level instrument clusters.
