Glucose Meter

Solution

Blood Glucose Meters are used to determine the concentration of glucose in a patient's blood. Glucose concentration is an important quantity for the management of diabetes. Key differentiators include ease of use, convenient size and low-power consumption.

Glucose Meter Block Diagram

Microchip has what glucose meter designers need:

  • Lowest power (sleep currents down to 9nA, run current down to 30 µA/MHz) PIC® MCUs enable long battery life designs.
  • Sleep mode flexibility: RAM retention, fast wake up and flexible wake up sources
  • Analog components, such as low-offset/low-noise op amps and high resolution ADCs, can be used for amplification, conditioning and conversion of the test strip socket output.
  • Cost-efficient, highly integrated PIC microcontrollers that can lower the BOM cost of glucose meter designs. Integration features include analog signal conditioning, LCD control and mTouch input sensing.
  • Other peripherals integrated into Microchip's MCUs include:
    • A Charge Time Measurement Unit (CTMU) which can provide a constant current source with a range from 0.55 µA to 550 µA.
    • Real-Time Clock/Calendars (RTCC) with functions for timekeeping, alarms and calendar applications. These devices offer highly configurable alarms and have the ability to wake up external devices without CPU intervention.
