This report presents a Digital Functional Analysis of the Apollo2 die found inside the AmbiqMicro C01 microcontroller unit (MCU). The AmbiqMicro C01 MCU was extracted from the Huawei ERS-B29 band 2 Pro activity tracker with heart rate monitor.

This report contains the following detailed information:

• Selected teardown photographs, package photographs, package X-rays, die markings, and die photographs
• Scanning electron microscopy (SEM) plan-view micrographs showing the layout of the die at the levels including, fin/STI, gate, contacts, and minimum pitch metals
• Measurements of horizontal dimensions of some of the major layout features, particularly the pitch and track height of standard cells
• Plan-view optical micrograph of the die delayered to the metal gate level
• Identification of major functional blocks on a gate level die photograph
• Table of functional block sizes and percentage die utilization
• High-resolution top metal and gate level die photographs delivered in the ICWorks Browser
