Could anyone hook me up with the IMU's datasheet?

I’m working on a project involving the Rift S and I need some very specific information from the gyroscope/accelerometer’s datasheet. I’ve found a HD image of the main board, and the chip that looks to be the IMU (the separate PCB in the middle between the two cameras) looks like it says R7FC AE4, but I wasn’t able to find anything useful on google.
