It can serve as one of the standard clinical diagnostic bases, improving efficiency.

Main Functions of the Chip:

• The ADC measures the voltage signal after the current sampling conversion circuit, which is used to calculate concentration.

• The DAC can output a precise and stable reference voltage for the three-electrode electrochemical measurement process.

• SPI displays the calculated concentration.

• The 4KB RAM can store measurement results in batches, enhancing testing efficiency, with data written to Flash before shutdown.

• The RTC displays the time.

• The buzzer serves as a reminder during usage.

• Supports key wake-up function.

• Built-in temperature sensor to display temperature, used for temperature compensation.

Application Advantages of the N32L406 Chip:

• 4.5Msps high-speed ADC sampling for precise and rapid measurement of target signals.

• Data retention and quick wake-up at ultra-low power consumption.

• Industry-leading ultra-low power consumption: 60μA/MHz dynamic operating power and 2μA static power, further extending battery life.

• Built-in hardware acceleration engine for cryptographic algorithms to ensure the security of internal protocol transmissions.

• High integration, incorporating multiple peripherals such as SPI, USART, ADC, DAC, and TIM.
