System Level Description
4.1 System Overview
This section describes on how the chip being used to make up a complete system including the explanation on the 3rd party
components and how they work with the chip.
The PAH8002 is based on CMOS image chip technology. It is designed to meet the requirements as heart rate monitor
accessories and wearables like smart watch or wrist band device. Figure 5 illustrates a system design for App Level diagram.
The processor is accessing PPG data from 8002 chip, then pass it to App level. APP level applies PixArt provided algorithm
library to determine the heart rate data and waveform. Figure 6. System Design for Firmware Level illustrates a system
design for Firmware Level diagram. The processor will also access PPG data from 8002 chip, then perform heart rate
calculation with PixArt algorithm library and send result to display or end device.
PAH8002 can be configured to generate different frame rate settings up to 50K fps.
