2.3 Quick Start The T89C5121-SK1 Starter Kit includes a T85C5121 and a T89C5121 microcontroller.
The demonstration board and accompanying software allow you to read data from a
smartcard and display it on a host PC.
You can also load your own application (in .hex file format) to retrieve data from a smart-
card or a credit card.
2.4 Connecting the
Microcontroller The T8xC5121 Demonstration Board is designed to support two different microcontrol-
lers, T85C5121 and T89C5121.
The microcontrollers are connected either on the bottom or top of the board, respec-
tively.
The T89C5121 requires the use of the SSOP24 Adapter which must be plugged into the
DIL support. Alternatively, the T89C5121 can be soldered on the board.

Connection 1. A 9 - 12V power supply must be connected to the J3 connector.
2. A serial cable must first be attached between COM PC port and J2 DB9 connec-
tor of the demonstration board.
3. Ensure the T89C5121 or the T85C5121 microcontroller is connected to the
board.
4. The ON/OFF Switch (SW3) must be ON. See Figure 3-1.
The Board is delivered with one 14.7456 MHz quartz (Y2).
2.6 Power Supply
2.6.1 Board Supply The Board can be powered from:

3.3 Reset The on-chip Power-on Reset function generates an internal Reset at power-up.
The external reset push button is provided to easily generate a warm reset during the
ISP process. See Figure 3-1.
3.4 Clock Crystal can be installed on the Y2 socket.
To use an external Clock, the input must connected to the optional J1 connector and a
jumper must be placed at JP19. See Figure 3-1.
3.5 EA Switch EA switch inside the SW6 Dip switch is by default connected to Vcc.
Figure 3-2. Default Configuration: switches opened
3.6 INT1 Switch The INT1 configuration switch (SW6 dip switch) selects whether or not the INT1 push
button is connected to port pin P3.3 on the microcontroller. See Figure 3-1.
3.7 Serial Port The Board supports a MAX232 at U5 (See Figure 3-1) to convert RS-232 voltage levels.
The serial I/O P3.0/RXD, P3.1/TXD can be disconnected using the JP5, JP6 jumpers.
3.8 LEDs The JP13 and JP14 jumpers placed in series with the LED0 and LED1 can be used to
monitor the LED current or to disconnect the LEDs.
3.9 Smart Card
Interface
3.9.1 Card Detection Card detection, by default, uses the on-chip internal pull-up register and the jumper JP9
connected to Vss. This configuration detects the low level input.
Another configuration can be used to detect a high level input when the card is inserted.
This is done using the jumpers JP8 and JP15. In this case, it is necessary to first discon-
nect the internal pull-up resistor, using accompanying software. See Section “Software

Microcontroller Programming
The CD-ROM includes:
 The demonstration software designed to read cards
 The software tool for ISP: FLIP (Flexible In-system Programmer)
 The terminal software: Quickterm - to interface the card access on host
 The SCI library including software drivers in C language
4.1 FLIP Software FLIP is software that runs on Windows 98®, Windows NT®, XP or Windows 2000®. FLIP
supports in-system programming of Flash C51 devices through RS232. The latest ver-
sion of FLIP software is available on the Atmel web site, www.atmel.com.
4.2 Programmingthe
T89C5121
(SSOP24
Package)
The on-chip internal EEPROM of the T89C5121 version can be programmed using
either:
 External EEPROM Atmel AT24C128
 Serial RS-232
4.2.1 Programming from
External EEPROM
Source
After Reset, if an AT24C128 EEPROM is detected at U1 (see Figure 4-1), the on-chip
ROM Bootloader downloads the external EEPROM content (16K bytes) in the on-chip
EEPROM and in the Code RAM.
Figure 4-1. EEPROM at U1 of Demonstration Board

Microcontroller Programming
4-12 T8xC5121 Starter Kit User Guide
4186E–SCR–05/04
When the download is achieved, the Bootloader runs the program.
This process has duration of 7.5 seconds at 14.7456 MHz.
Figure 4-2. Bootloader Diagram
As specified in the T89C5121 datasheet, the two highest addresses of the 16K bytes
code must contain the program CRC and the bootloader compares with computed CRC
to launch (or not) the program execution.
The CRC value can be calculated with FLIP Software: the user must load the Hex file
and press the button: CRC.
The updated buffer can then be saved as a new Hex file including the two CRC bytes.
CAUTION: The Jumper JP14 (LED1) must be removed. Otherwise the TWI Clock signal
will not be at the correct levels.
4.2.2 Programming from
RS-232 source A serial cable must first be attached between COM PC port and J2 DB9 connector of the Demonstration board.
After Reset, if a AT24C128 EEPROM has not been detected at U1, the on-chip ROM
Bootloader tests if the UART receives ‘U’ (0x55) characters. Then, commands can be
sent to the microcontroller, using FLIP software. The programming sequence is detailed
in Section 5.
When the Program command is processed, the Internal EEPROM is programmed at the
same time as CRAM.
The program execution can be launched from FLIP (RUN Application Button).

4.2.3 Using Pre-
programmed Parts If neither AT24C128 External EEPROM nor RS-232 programming has been detected, the on-chip ROM Bootloader downloads the internal EEPROM content (16K bytes) in
the Code RAM and runs the corresponding program.
Note: This assumes that, previously, the T89C5121 microcontroller has been pro-
grammed.
After reset, execution of the program takes 4 seconds at 14.7456 MHz.
4.3 Programmingthe
T85C5121 The T85C5121 version can be loaded in CRAM with the application program and exe-
cuted once connected to the Demonstration Board. See Figure 2-2.
The processes are the same as for T89C5121 (RS-232 and External EEPROM) except
that there is not an internal EEPROM and so the standalone configuration is not valid.
4.3.1 Programming from
External EEPROM
Source for SSPO24
package
After Reset, if an AT24C128 EEPROM has been detected at U1 (see Figure 4-4), the
on-chip ROM Bootloader downloads the external EEPROM content (16K bytes) in the
Code RAM.
Figure 4-4. EEPROM at U1 of Demonstration Board
4.3.2 Programming from
External EEPROM
Source for PLCC52
package
The PLCC52 Package Product can be programmed using either :
 External EEPROM Atmel AT24C128 at U6 location
 External EEPROM Atmel AT24C128 at U1 location
 Serial RS-232
The two last processes are the same as for T89C5121 (RS-232 and External
EEPROM).
The first process can use an external EEPROM which is seen by the Bootloader as the
Internal EEPROM of the AT89C5121 Product version.

After Reset, if an AT24C128 EEPROM has been detected at U6 (see Figure 4-1), the
on-chip ROM Bootloader downloads the external EEPROM content (16K bytes) in the
Code RAM.
CAUTION:
If the ROM code marked on the package is DRW (Bootloader 1.2.2 version) or higher,
an hardware modification must be done on the 1.2.0 version Demoboard.
The wires to pins 5 and 6 of U6 must be cut. In place, the following wires must be added
Pin 26 of PLCC52 (P2.3) must be connected to U6.6
Pin 29 of PLCC52 (P2.0) must be connected to U6.5

Note: The T8xC5121 card reader can adapt to 3V or 5V smart cards. Select the corre-
sponding demonstration software depending on your card.
The message ‘HEX file exchange.hex loading done’ is displayed at the bottom of the
FLIP window.
7. Ensure the following check boxes are selected in the Operations Flow section of
FLIP:
- Erase
- Program
- Verify
These are the operations that will be performed on the microcontroller.
8. Press the ‘Run’ button. Programming is executed.
The “Memory Verify Pass” message confirms programming is successful and
that the microcontroller has been programmed.
