5 Connectors

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 DC input to minimize the power dissipation of the voltage

regulators.

All pins (except oscillator Pins) of the microcontroller are directly connected to X1 and X2 as

follows:

Connector

X1 (1 – 50)

X2 (51 – 100)

The odd pin numbers are located on the one side and the even pin numbers are located on

the other side of the connector.

Two 9-pin D-Sub female connectors are used

for the serial interface 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 a 1:1 cable for PC-connection.
