RX231 MCU for Blood Glucose Meters

Renesas’ RX231 MCU provides an interface for the BLE module, touch sensing, LCD control, and USB communication

Image of Renesas/IDT's Blood Glucose MetersBlood 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.

Features
  • Highly integrated RX231 with built-in capacitive touch
  • Programmable gain to maximize the output signal voltage for all inputs
  • Reliable humidity and temperature measurements
  • Simple voltage supply with low-current consumption
