5 Connectors
5.1 Power connector
(X12)
The following figure shows the power connection jack X12. This connector is used to
connect an external unregulated DC power supply voltage (9V-12V DC) to the evaluation
board.
Connector X12:
It is recommended to use 9V to keep the power dissipation to a minimum. Otherwise, an
additional heat sink for the linear voltage regulator might be necessary.
5.2 Edge connector
(X1, X2)
All pins of the microcontroller are directly connected to X1 and X2, both are 2 x 12 Pin
headers, as follows:

X2 (25

– 48
The odd pin numbers are located on the one side and the even pin numbers are located on
the other side of the connector.
On the PCB, the corresponding pin numbers of the µC are written next to the connector pins.
5.3
UART”A”, UART”B” connector
(X3, X5)
Two 9-pin D-Sub female connectors are used
for the serial interfaces UART”A” and UART”B”.
TXD is the transmit output, RXD is the receive input.
The DTR or RTS signal can be used to generate a reset.
Please use 1:1 cable for PC-connection.
Note: UART”B” (X5) is only available within
MB90895 Series, MB90360, and MB90960 Series.
Connector X3, X5:
Shield is connected to positive voltage supply
