blood glucose meter

A blood glucose meter is a medical monitor used by diabetic patients to measure changes in their own blood sugar levels and to remind diabetic patients to change their daily eating habits. It must include an ultra-low-power microcontroller, LCD display, voice prompts, real-time clock, data storage, implement blood glucose algorithms and provide Universal Serial Bus (USB) functionality or Bluetooth Low Energy (BT BLE 4.0) wireless communications , with App application software to upload data to computers, tablets, and smartphones. Since it needs to run at very low power consumption and have long-term standby and battery power supply, the Nano130 series is suitable for use in blood glucose meters.
The Nano130 series provides high-performance, low-cost, ultra-low power consumption 32-bit Arm® Cortex®-M0 core, running speed up to 42 MHz, built-in 32-bit hardware multiplier, low operating voltage 1.8V ~ 3.6V, ultra-low power operation mode (< 200 uA/MHz), power-down mode (real-time clock + LCD display on, memory data saved < 10 uA), (real-time clock, memory data saved < 2.5 uA), deep power-down mode (memory data saved < 1 uA), flash memory up to 128 KB and RAM memory up to 16 KB, highly integrated RTC, LCD driver controller, 12-bit ADC conversion rate up to 2 Msps, built-in 12 MHz RC oscillator and USB 2.0 full-speed device to reduce system BOM cost . Rich peripheral interfaces I²Cx2, SPIx3, UARTx5 and anti-theft copy lock code bit function, 96-bit UID chip unique code, 128-bit UCID customer unique code, strong anti-interference ability (ESD 8kV / EFT 4kV).
