Bluetooth, Processor and Power Solutions for Medical Applications

STMicroelectronics offers a full range of components for medical applications. These include advanced STM32 processors, Bluetooth modules and power solutions including IGBTs (Insulated Gate Bipolar Transistors).

STMicroelectronics’ STM32 range of 32-bit Flash microcontrollers is based on the ARM Cortex™-M3 core. With low voltage (2.0V to 3.6V) operation, the MCU devices provide extremely low active power consumption of 0.5mA/MHz and standby currents as low as 1.4µA.



STM32 family devices use the Thumb-2 instruction set to improve code density and hence reduce memory requirements, while delivering deterministic, real-time operation and fast interrupt response.

To cater for the needs of safety-critical applications, STMicroelectronics provides a complete suite of self-diagnostic firmware routines to test STM32 core functions efficiently according to IEC60335 Type B. Certified by VDE, the routines are ready to integrate into any application.

STMicroelectronics’ BlueModule products are extremely stable and reliable Bluetooth core-embedded modules. Available in both Class 1 and Class 2 versions for a choice of long range or low power, they support protocol layers up to HCI.



Modules are available to comply with Bluetooth v1.2 and v2.0 specifications, including Enhanced Data Rate (EDR) options. STMicroelectronics Bluetooth products successfully passed the first set of interoperability tests on the Bluetooth Medical Profile in an official standardisation committee event.

Modules can be fully controlled using AT commands, implementing all Bluetooth core protocols and Serial Port Profile (SPP). Typical applications include continuous monitoring of patient temperature, respiratory rate, blood oxygenation and heart rate.



Applications such as automated external defibrillators require high-voltage boost control switching that is best provided by an IGBT. STMicroelectronics offers a number of components of this type specifically aimed at medical applications. These include the 1200V G7NB120SD1, with a specified collector current of 7A and VCE of 2.3V at +70°C. Available packaged or as a bare die, this device will soon be supplemented by a 2500V device, the STGHixxxN250S, which shares its low quiescent current characteristics.
