System Overview

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.
