2.4 Processor STM32F103RB from STMicroelectronics

2 Electrocardiogram (Ecg) Signals

2.4.1 Features

The STM32F103RB from STMicroelectronics is a processor with a ARM 32-bit Cortex-M3 CPU
The Electrocardiogram (Ecg)
and peripherals. STMicroelectronics is reshaping the 16/32-bit MCU market with they'r STM32
family.
• Ecg: electrical manifestation of heart activity recorded
The key benefits of the STM32F103RB are:
from the body surface
Leading performance, real time behavior
• monitoring of heart rate
A lot of peripherals
Outstanding power efficiency
In production since 2007
The Ecg signal can be recorded fairly easily with surface
70 part numbers across 4 product lines
electrodes placed on the limbs and/or the chest, see pages
below.
SW Libraries are free available from
