Power rails
In all the tables contained in this manual, the power rails are named with the following meaning:
V
IN
: Power In voltage (in the range +12V
DC
..+24V
DC
) directly coming from the Power Supply connectors CN1 or CN2
3V_BAT: 3V power rail for supplying the optional Ultra Low Power RTC
+5V_A: +5V power rail, directly generated from VIN power rail, immediately available when VIN voltage is applied.
+3V3_A: +3.3V power rail, directly generated from VIN power rail, immediately available when VIN voltage is applied and 5V_A voltage is stable.
VDD_3V3: main +3.3V power rail generated by the on-board PMIC powered by 5V_A power rail.
VDD_1V8: main +1.8V power rail generated by the on-board PMIC powered by 5V_A power rail.
+3.3V_AUX: Auxiliary 3.3V Power rail, derived from +3.3V_A rail when VDD_3V3 power rail is stable.
+3V3_OUT: 3.3V power rail specific for I/O connectors, derived from +3.3V_A power rail upon SW enabling.
NVCC_SNVS_1V8: +1.8V power rail for GPIO Pre-driver in SNVS (secure non-volatile storage) bank, generated by the on-board PMIC.
