NAND flash bank
On board main storage memory is a 8-bit wide NAND flash
connected to the CPU's Raw NAND flash controller. Optionally,
it can act as boot peripheral.
The following table reports the NAND flash specifications:

Power supply unit
AXEL, as the other ULTRA Line CPU modules, embeds all the
elements required for powering the unit, therefore power
sequencing is self-contained and simplified. Nevertheless,
power must be provided from carrier board, and therefore
users should be aware of the ranges power supply can assume
as well as all other parameters. For detailed information,
please refer to Section 5.1.
3.7
CPU module connectors
All interface signals AXEL provides are routed through three
140 pin 0.6mm pitch stacking connectors (named J1, J2 and J3).
The dedicated carrier board must mount the mating connectors
