MCU based medical alarm with supercapacitor backup reference design


Design files


This reference design is an non-application specific example medical alarm utilizing the MSPM0G1507 or MSPM0G3507 microcontroller (MCU) that demonstrates primary alarm, backup alarm and visual alarm functionality to assist with development in accordance with IEC 60601-1-8.

  • Capability to play standard and custom alarms with 128 kB internal flash and external flash options
  • 12-bit adjustable frequency (48 kHz+) high-fidelity audio using integrated DAC
  • Over three-minute backup alarm using supercap backup
  • Three visual alarm LEDs with high, medium and low priorities
  • 49 mm diameter small form factor for space constrained medical applications
