electrocardiograph

The electrocardiograph is a medical monitor that is used in patients with irregular heartbeats to analyze heartbeat patterns and identify irregular heartbeats in advance, which can prevent palpitations, cardiac arrest, and shock. .It must include an ultra-low power microcontroller, LCD display, real-time clock, data storage, high-precision 24-bit analog-to-digital converter, and execute ECG algorithm to convert data into electrocardiogram waveforms, which are displayed on the LCD display in real time. It also provides Universal Serial Bus (USB) function to upload data to computers, tablets, and smartphones. Due to the need to run at very low power consumption and have long standby times with battery power, the Nano120 series is suitable for application in electrocardiographs.
The Nano120 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, memory data retention < 2.5 uA), deep sleep mode (memory data retention < 1 uA), flash memory up to 128 KB and RAM memory up to 16 KB, high integration Real-time clock, 12-bit ADC conversion rate up to 2 Msps, built-in 12 MHz RC oscillator, USB 2.0 full-speed device 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).
