Apple included the M11 in the iPhone 8, 8 Plus and iPhone X, embedded within the A11 Bionic SoC. The iPhone 7, iPhone 7 Plus, second-generation iPad Pro feature the M10 motion coprocessor, embedded within the A10 Fusion and the A10X Fusion chips. September 2015 brought the M9 motion coprocessor embedded within the A9 chip found in the iPhone 6S, iPhone 6S Plus, first-generation iPhone SE and within the A9X chip found in the first-generation iPad Pro. The later coprocessors are embedded into the A-series SoCs. iFixit have identified the M8 in the iPhone 6 to be an NXP device with a very similar name, the LPC18B1. The updated version M8 was introduced in September 2014 with the iPhone 6 and also processes data from the barometer that is included in the iPhone 6 and iPad Air 2. It uses an ARM Cortex-M3 core with a customised packaging and naming scheme indicating that it is for an Apple customized part. Chipworks found that the M7 most likely is a NXP LPC1800 based microcontroller called LPC18A1. The first coprocessor of the series is the M7 (codename Oscar), which was introduced in September 2013 as part of the iPhone 5S. First released in 2013, their function is to collect sensor data from integrated accelerometers, gyroscopes and compasses and offload the collecting and processing of sensor data from the main central processing unit (CPU). The Apple M-series coprocessors are motion coprocessors used by Apple Inc.
