Apple 343S00008-A1 (STMicroelectronics UAV8AC Die) Apple Pencil Sensor Driver ASIC Basic Functional Analysis Report
This report presents a Basic Functional Analysis of the STMicroelectronics UAV8AC die found inside the Apple 343S00008-A1, extracted from the Apple Pencil. The Apple 343S00008-A1 IC was found near the nib of the Apple Pencil. The Apple Pencil is a stylus designed to work with the iPad Pro. The stylus is sensitive to both the pressure and angle of the stylus with respect to the tablet surface. This report contains the following detailed information: • Selected teardown photographs, package photographs, package X-rays, die markings, and die photographs • Scanning electron microscopy (SEM) cross-sectional micrographs of the general structure of the die dielectric materials, major features, and transistors • Measurements of vertical and horizontal dimensions of major microstructural features • Plan-view optical micrograph of the die delayered to the polysilicon layer • Identification of major functional blocks on a polysilicon die photograph • Table of functional block sizes and percentage die utilization • High resolution top metal and polysilicon die photographs delivered in the ICWorks Browser • Cost of die and tested packaged die, based on the manufacturing cost analysis of the observed process
