5.2.    Operation conditions
The recommended operating conditions are as follow:
 
Supply voltage:
VCC = 3.3VDC ?0.3VDC
Temperature:
T = -40癈 to +85癈
 
5.3.    Electrical
5.3.1. Operational ranges
Since the voltage regulators threshold is fixed to 3.3V DC, operation is uncritical as long as
input voltage is above 3.3V. Below, operation is not recommended since assembled compo-
nents (MCU, Flash, EMAC, I2C-Sensors) will start to fail. The probability that they do grows,
the lower the voltage is. For concrete working voltage ranges please refer to the table below
as well as the respective components datasheets.
To avoid unstable behaviour, the board supplies a reset supervisor which drives a pin low, if
the input voltage sinks below 2.4V DC (deRFnode/gateway for AVR) respective 3.0V DC
(deRFnode/-gateway for ARM). This pin is routed to the radio module MCUs reset entry
(Pin5). To enable a too low voltage causing a MCU reset, JP4 must be closed. On ARM-
MCUs the reset supervisor must be explicitly enabled (see section 8.4).
