Pulse Oximeter
详情介绍
Overview
MCUs in the 78K0R/Lx3, the R8C/Lx and the RL78/L1x Series from Renesas Electronics integrate the on-chip A/D and D/A converters required in pulse oximeters, as well as an LCD drive-control circuit. These on-chip features reduce the number of external components required, making the MCUs ideal choices for pulse oximeter products that must combine compact size and low cost.
