The IS31SE5118 brings some of the same features in a smaller 16-pin package and up to nine Cap-Sense keys. Based on the IS31CS8975 MCU, it also uses Sigma-Delta technology, has a Shield driver for moisture resistance, and very low power with wake-on touch. The engineer should mention that the underlying MCU, IS31CS8975, comes also in an 8-pin package for smaller applications with smaller size and lower price point. The MCU option also offers an ADC in cases there is such a requirement.
