The Pulse Oxi-meter is a medical monitor meter used for patients
with vascular disease or respiratory disease and cardiopulmonary organ aging
persons to measure the oxygen saturation (SpO2) and pulse rate.
It must include an ultra-low-power microcontroller (MCU), LCD
display, RTC, data storage, runs an Oxygen Saturation algorithm and provides
the data upload function to PC, Pad, or Smart phone through BT4.0 BLE wireless
communication with App software.
Due to the need to run at very low power and long-time standby
with battery powered, the Nano100 series is suitable for Pulse Oximeter
The Nano100 series provides high performance and low-cost
ultra-low-power 32-bit Arm® Cortex®-M0 core, runs up to 42 MHz, and supports
32-bit hardware multiplier, Low operating voltage 1.8V to 3.6V, Ultra-low power
operating mode (< 200uA/MHz), Power-down mode (RTC, RAM retention<
2.5uA), Deep Power-down mode, RAM retention (< 1uA), Flash up to 128 KB and
RAM up to 16 KB, high integrated RTC, 12-bit ADC, 2 MSPS conversion rate,
internal RC 12 MHz OSC to reduce system BOM cost, rich peripheral I²Cx2 ,
SPIx3, UARTx5, Anti-theft lock code bit, 96-bit Unique ID and 128-bit Unique
customer ID, and strong anti-jamming ability (ESD 8kV, EFT 4kV).
