Advanced Glucose Meter with AVR XMEGA


Key Design Considerations:

  • Ultra-Low System Power Consumption
  • High System Integration for low cost and small footprint
  • High Connectivity

Why the Designer Picked Atmel

ATXmega256A3BU offers ultra-low power consumption, high integration, compact package and connectivity features to address the needs of a glucose meter:

  • Ultra-Low-Power
    • ATXmega256A3BU supports 1.62 to 3.6V and has five flexible sleep modes
    • In power-save mode (RTC running), the current consumption is below 1µA
    • In active mode, the current consumption is 350µA/MHz at 1.8V
    • DMA controller handles data transfer between peripherals and memory
  • Connectivity
    • Full-Speed USB device port with embedded PHY saves BOM cost (~$0.5-$1.0). It can be used for battery charging and data transfer to a PC.
  • High Integration
    • Integrated UART, USART, SPI and I2C, allow easy connection to external sensors, memories and display
    • Minimum external hardware thanks to integrated RTC, high-performance ADC and DAC, PLL (phase-lock loop), and voltage reference
