STMicroelectronics 4x4mm MEMS gyro was integrated in the previous iPhones (iPhone 4,
4S & 5). For the new iPhone 5S, Apple has chosen the latest 3x3mm MEMS gyro from ST, thus
achieving a 45% footprint reduction.

The new 3-Axis MEMS gyroscope is assembled with a true CSP process (Chip Scale
Packaging) allowing a package efficiency of 75% (silicon area/package area). This
packaging size reduction combined with dies shrinking allowed ST to reduce by 20% the
production cost of their latest gyro.

This report provides a complete teardown of the MEMS gyro with:
