Socket and Quartz Crystal

The C51/C251 Demo Board provides three different sockets for microcontrollers, a PLCC44, a PLCC68 and a DIL24.

Each socket has it own quartz crystal X1, X2 and X3.

Only one Atmel microcontroller must be plugged at one time, in one of the three socket.

Crystal may be easily changed on each socket.

6.1.1. Switch Configuration

To program the on-chip Flash memory, hardware configuration of the chip

should be the following: PSEN = 0, EA = 1 and ALE = 1 or not connected.

On C51/C251 Demo Board, switches must be as shown on Figure 11

Figure 11. C51/C251 Demo Board Switches Configuration to use ISP.

6.1.2. Running ISP

The C51/C251 Demo Board must be connected to a PC com port via RS232 cable connected to RS232 connectorof C51/C251 Demo Board.

After downloading you can run your code by switching PSEN on J11 to 1 and press RESET push button.

6.2.3. ISP Operation

First connect C51/C251 Demo Board to PC com port with cable.

Run Windows (see Note 2) hyper terminal and configure it with above parameter. (see figure13)

C51/C251 Demo Board

Turn on the C51/C251 Demo Board and then follow instruction on terminal screen and LCD display.After erasingflash, the program ask for memory zone, and then ask to send HEX file in text mode.(see figure 14, 15 & 16)

Figure 15. Send HEX file in text mode

Figure 16. Use *.* in selection zone to see HEX files into directory

Rev. B - Jan 12, 2001 11

C51/C251 Demo Board

After the download of HEX file, the program ask if you want to download another HEX file in the second

zone of the external flash memory.

In this case you�ll have to switch MAP SELECT (to access second zone) and send another HEX file in text mode.

All the external flash memory (128Kbytes) is erased when ISP is used, even if you only want do download one zone.

If you have one external flash memory zone programmed, and later you want to add another program to the

second memory zone, you will have to download both program at the same time.

6.3. Demo ModeIn demo mode, programs stored into external flash memory are executed to demonstrate capability of AtmelMicrocontrollers. To run external code we must have EA=0.

In this mode the first four bits of J11 (UC3:0) are used to select demo program and UC4 is used to select display(LCD or RS232).

CAN Extension Board User�s Manual

1. IntroductionThis board is an evaluation board dedicated to the Atmel T89C51CC01 microcontroller. The CAN demoboardExtension is plugged to the demoboard connector. All features provided by the demoboard can be used (LCD, ledbargraph, 128kB Flash memory, hardware capability to program the T89C51CC01 on-chip Flash memory, etc.).

2. FeaturesThe CAN Demoboard Extension works with the following T89C51CC01 features:• CAN (on board CAN transceiver SI9200DY).• Two different sockets for transceiver: DIL8 & SO8.• D-sub connectors compliant to the CiA (User Group:"CAN in Automation") recommendation for the CAN High

Speed Bus.• Analog-to-Digital Converter (Connector for ADC reference voltage VAGND and VAREF).

4.1. Block Diagram

Figure 2. Block Diagram

4.2. CAN PartsDifferent kinds of transceiver can be plugged on the board (Si9200, PCA82C250 ...) on socket DIL8 or SO8.Please pay attention to have only one transceiver on the board.

Jumper J10 allows to connect or not the 120 Ohm termination resistance. The CAN High Speed Bus must beterminated at both ends with a termination resistance for proper operation.

4.3. ADC PartsTo use ADC feature, a reference voltage must be applied on VAGND and VAREF (3 Volts).

When the ADC is addressed, you cannot control the LCD or the led bargraph because Port1 must be left free.Therefore pay attention on P3.2 and P3.4 states that are used to select LCD and bargraph (see Table 1).

The Port 1 pins are input for Voltage to convert.
