Hardware Description
4.1.2
VertiCal Base Board
The
printed circuit board (PCB),
one of the VertiCal base board components, is used
as a base to mount the other components of the VertiCal base board.

VertiCal Base Board
The upper side of the
printed circuit board
is fitted with
• the microcontroller device (packaged into the specified CSP package),
• the VertiCal connector (standardized 156-way connector).

VertiCal Base Board (fitted with Solder Balls, Side View)
The lower side of the
printed circuit board
has a
footprint similar to that used by MPC5500
family devices in standard production packages.
The
lower side of the board is fitted either
• with solder ball footprints for direct and permanent soldered connection
to the development ECU PCB (see Fig. 4-3) or
• with a "BGA adapter" connector allowing connection and removal from
an ECU development PCB which has been fitted with a compatible "BGA
receiver" socket (see Fig. 4-4).

Typical Usage
The standard ECU microcontroller is replaced by the VertiCal base board with the
same dimensions and the same pinout.
The VertiCal base board connects the ECU with the XETK-V1.0.
