RX231 MCU for Blood Glucose Meters

Blood glucose meters measure blood sugar levels and help monitor health conditions. Renesas’ RX231 MCU aids in fulfilling the increased demand for these effective metering solutions. The RX231 provides an interface for the BLE module, touch sensing, LCD control, and USB communication in one package. The ISL28214 is used for the transimpedance amplifier thanks to its low input offset and bias currents, while the ISL90727 digitally-controlled potentiometer provides programmable gain. The HS3001 temperature and humidity measurements enable offset calculations on the signal for accurate measurements. Renesas’ ISL9001A ensures a proper voltage is always maintained.
