CHIPO2 is a mixed signal semi-custom IC that combines the major parts of Pulse Oximetry analog front-end with Oximetry Computational Module.

It includes:

  • Analog Section
  • Oximetry Control Section
  • 16-bit RISC Processor
  • RAM
  • Flash ROM containing proprietary Pulse Oximetry Algorithm
  • Parallel I/O
  • Serial I/O (UART, PI, I2C)


  • Powered by 3.3V, Oximetry Sensor could be powered either by 3.3V or 5V
  • Power Consumption (when running Oximetry only, excluding sensor): 0.6mA & 3.3V
  • Compatible with industry standard Pulse Oximetry sensors (red wavelength 660nm/infrared wavelength 905nm)

Low cost CHIPO2 offers a great deal of flexibility in product developmentand its system integrations, with a reliable performance level of standardPulse Oximetry.
