Hardware Description
2.2 Power Supply The on-board power supply circuitry allows various power supply configurations.
The power source can be:
– VBUS from USB (5V)
– VBUS from USB (5V) through the current limiter
– External power supply (from 6 to 12V) or 9V battery
The voltage output can be the direct power source, regulated at 5V or 3.3V.
The power supply selection is performed using the JP2, JP3, JP4 and JP5 jumpers.
The power supply can be turned on/off using the “power” switch (SW6). Once the poweris established, the power LED (D9) is lit.

Hardware Description
2.3 C51 Standard Settings
2.3.1 Reset The external Reset push-button (SW3) is provided to easily generate a warm reset. Thisbutton is used for ISP process. The Reset applied is active low.
2.3.2 Clock A crystal can be easily installed on the Y1 socket. The clock can also be provided usingthe J8 connector instead of the crystal.
Note: Remove the clock generators before the using the programmer.
2.3.3 EA Place a jumper on the EA connector (J10) to force the EA pin to ground and executeexternal code. Otherwise internal code will be executed.
Figure 2-3. EA Circuitry
2.3.4 INT0 In order to use the on-board INT0 circuitry, connect the J7 Jumper to the AT89C5131A.
When you press the INT0 button (SW5), the P3.2 pin will go low which induces an inter-rupt event.Note: Remove the J7 jumper before using the programmer. Otherwise the program-
mer will not function.

2.4.2 USB Peripheral The AT89C5131A evaluation board provides all the required hardware to develop aUSB firmware for the AT89C5131A, this includes:
– a USB connector
– 2 test points on D+ and D-
– 1 test point on VBUS
– a USB UNLOAD button which allows to disconnect the pull-up on D+ and thento simulate an Attach/Detach of the USB cable
The USB peripheral can also be used to perform an In-System Programming.

Hardware Description
2.4.3 TWI Peripheral The CT3 and CT5 contacts have to be soldered in order to use the SDA and SCL alter-nate P4.1 and P4.0 port configuration on the SPI connector (J4).
In order to use these signals on the J5 extension connector (SDA and SCL), the CT4and CT6 contacts have to also be soldered.
2.4.4 SPI Peripheral
2.4.5 LED Controller The AT89C5131A controller includes an LED controller on:
– P3.3 (LED 0)
– P3.5 (LED 1)
– P3.6 (LED 2)
– P3.7 (LED 3)
The on board LEDs can be controlled with the AT89C5131A if the corresponding con-tacts CT9, CT10, CT11 and CT12 are bypassed.

Device Programming
3.1 In-System Programming
The user memory of the AT89C5131A part can be programmed using the ISP mode ofthe device. In order to enter in ISP mode, first select the high pin count mode (PSEN) orthe low pin count mode (P1.0) using the ISP switch (SW2).
To enter in ISP mode, press both the RESET (SW3) and ISP (SW4) buttons simulta-neously. First release the RESET button and then the ISP button. The device enters inISP mode.
ISP can then be performed using the USB bus (or with the peripheral correspondingwith the bootloader version). The user may need to re-enumerate the USB bus using theUSB UNLOAD button (SW1) if the USB cable is already connected.
3.2 Using a Programmer
The AT89C5131A microcontroller can also be programmed using a programmer withthe J3 connector. Connect all required signals between the programmer and the J3 con-nector and remove the J7 jumper to disconnect the EA circuitry. No clock should beenabled on the board, except the clock coming from the J3 connector.
