Power, reset and control
AXEL ULite system-on-module (SOM for short) is powered by carrier
board via VIN_SOM rail.
About voltage range, three supported configurations are available. These
configurations are indicated by the value of the f field of the ordering
code. The generic ordering code is in the form:
DA p l r n c f t s
The field f can assume the following values:
● 0,1: power supply voltage range 3.135 - 3.465V (that is
● 2: power supply voltage range is 3.3 - 4.5V
● please note that this range can be widened by the use of an
● 3: power supply voltage range is 3.25 - 3.465V (that us 3.3
Voltage references for single-ended I/O signals the same for all
configurations. They are detailed in the following table.
