The proliferation of sensors in mobile wireless and mobile-influenced products has created significant design challenges. Because there are no consistent methods for interfacing physical sensors, Device and platform designers are faced with digital interface fragmentation that includes I2C, SPI, and UART among others.
These design challenges include significantly higher signal count and increased bandwidth requirements.
To address these challenges the MIPI® Alliance has defined the I3CSM to ease sensor system design architectures products by providing a fast, low cost, low power, two-wire digital interface for sensors.
