Sensors are experiencing rapid growth in mobile devices – reaching a critical milestone of 10+ sensors and 20+ signals per device. To compound matters, the digital interface landscape is fragmented and current standard architectures do not scale to reach future demands.
To address these issues in collaboration with the MEMS Industry Group (MEMS IG), MIPI Alliance first formed an open “Birds of a Feather” (BoF) group that successfully completed a project to review the state of the industry, survey opportunities for establishing a sensor interface, and set requirements to guide future proposals.
The MIPI Board of Directors has now formed a Sensor Working Group (WG) to bring forward a solution for the mobile industry and beyond.
Sensor WG is actively developing the MIPI Specification for I3C, a a two-pin interface that is backward compatible with the I2C standard and provides data throughput capabilities comparable to SPI. Its name is derived from the Sensor WG’s goal to create an interface that will allow legacy I2C devices to coexist on the same interface as new devices that support I3C’s more advanced features. It is being developed with the participation of vendors from across the sensor and mobile ecosystems and will be offered to the industry under the technology name of SenseWire℠.
Sensor WG’s Specification is scheduled for completion by year-end 2014, with ratification and approval by the MIPI Alliance Board of Directors and publication in the first quarter of 2015. Companies that have not been involved in the development of the specification but want to participate in Sensor WG still have time to join the process, gain early experience with the technology and play a role in the direction of this work.
