Always-on Brownout Reset Brown-out reset (BOR) forces the MCU to reset both on power-up/down

When VCC rises and when VCC falls below normal operating range, a POR is triggered.

MSP430 for Energy HarvestingSelf or Perpetual - Power Apps

Energy harvesting is the process by which energy is captured and stored

Can substitute batteries that are costly to maintain and can extend system uptime

Only possible with ultra-low power components Solar, kinetic, thermal, RF, salinity gradients, pH

difference and other ambient sources available

Body worn monitoring devices powered by body heat, movement

Monitor conditions on farm, winery, etc.

Mesh networking for environmental monitoring (e.g. forest fire detection)

Automotive monitoring (e.g. tire pressure gauges powered by vibration)

Energy Harvesting Made Easy MSP430 Solutions

Native 0.9V Operation

Native Means The device, including peripherals operates at specified Vcc Additional components such as charge pump are NOT needed to

support the full Vcc range Full functionality of the device is maintained within Vcc range The microcontroller and application are supplied from one common

supply that goes down to min Vcc

0.9 1.65 V
