Demonstrating the scope of applications onsemi EEPROM portfolio addresses, this slide features an application example of an EEPROM in the medical market. The CAT24C64C4CTR can be found in many devices, including pulse oximeters and smart phones. In the application shown, the EEPROM memory stores calibration coefficients for the sensors in the Pulse Oximeter. Notice that in this Pulse Oximeter solution, onsemi also offers solutions for voltage references, processors, LCD backlighting, I/O interface, and much more.
