Oximeter

An oximeter is a medical monitor used in patients with vascular disease, respiratory disease, and the elderly with aging heart and lung organs to measure blood oxygen concentration (SpO2) and pulse rate. It must include an ultra-low-power microcontroller, LCD display, real-time clock, data storage, execute blood oxygen concentration algorithm and provide low-power Bluetooth BLE 4.0 wireless communication with App application software to upload data to computers and tablets ,smart phone. Due to the need to operate at very low power consumption and long-term standby with battery power supply, the Nano100 series is suitable for application in oximeter.
The Nano100 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), sleep mode (real-time clock running, data memory retention < 2.5 uA), deep sleep mode (data memory retention < 1 uA), program memory up to 128 KB and data memory up to 16 KB, Highly integrated real-time clock, 12-bit ADC conversion rate up to 2 Msps, and built-in 12 MHz RC oscillator to reduce system BOM cost. Rich peripheral interfaces I²Cx2, SPIx3, UARTx5, 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).
