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 applications.
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
