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 of our blood glucose meter solutions include ease of use, convenient size and low power consumption.

We Have What Glucose Meter Designers Need


  • Lowest-power (sleep currents down to 9 nA, run current down to 30 µA/MHz) PIC® microcontrollers (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 Analog-to-Digital Converters (ADCs) can be used for amplification, conditioning and conversion of the test strip socket output
  • Cost-efficient, highly integrated PIC MCUs that can lower the BOM cost of glucose meter designs with integrated features such as analog signal conditioning, LCD control and mTouch® technololgy input sensing
  • Other peripherals integrated into our MCUs include:
    • A Charge Time Measurement Unit (CTMU) that can provide a constant current source with a range from 0.55 µA to 550 µA
    • Real-Time Clock/Calendars (RTCCs) 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
