Infineon XMC4400 Enterprise Kit¶
Infineon XMC4400 Enterprise Kit is equipped with the ARM Cortex-M4 based XMC4400 microcontroller (MCU) from Infineon Technologies. These kits are designed to evaluate the capabilities of the XMC4400 MCU.
Pin Mapping¶

Flash Layout¶
The internal flash of the XMC4400 module is organized in a single flash area with 16 sectors. The flash starts at address 0xC000000.
| Start address | Size | Content |
|---|---|---|
| 0xC000000 | 16Kb | Zerynth VM |
| 0xC004000 | 16Kb | Zerynth VM |
| 0xC008000 | 16Kb | Zerynth VM |
| 0xC00C000 | 16Kb | Zerynth VM |
| 0xC010000 | 16Kb | Zerynth VM |
| 0xC014000 | 16Kb | Zerynth VM |
| 0xC018000 | 16Kb | Zerynth VM |
| 0xC01C000 | 16Kb | Zerynth VM |
| 0xC020000 | 128Kb | Bytecode Bank 0 |
| 0xC040000 | 256Kb | Bytecode Bank 1 |
Note
If flash memory must be used in a Zerynth program, it is recommended to begin using it from secure addresses towards the end the bytecode (start address of the bytecode can be found in the log console of Zerynth Studio during the uplink operation), leaving a minimum safe place to minimize the chance of clashes.

- 1 potentiometer
Power¶
Power to the XMC4400 is supplied via one of the two on-board USB Micro B connectors. However there is a current limit that can be drawn from the host PC through USB. If the board is used to drive other satellite cards and the total system current reuired exceeds 500 mA, then the xmc4400 needs to be powered by a satellite cards, which can support external power supply.
Connect, Register, Virtualize and Program¶
The Infineon XMC4400 comes with a usb debugger chip on board that allows programming and opening the UART of the module. Drivers are needed (Linux, Mac or Windows) and can be downloaded from the official JLink software page.
Note
For Linux Platform: to allow the access to serial ports the user needs read/write access to the serial device file. Adding the user to the group, that owns this file, gives the required read/write access: Ubuntu distribution –> dialout group; Arch Linux distribution –> uucp group.
Once connected on a USB port, if drivers have been correctly installed, the XMC4400 device is recognized by Zerynth Studio. The next steps are:
- Select the XMC4400 on the Device Management Toolbar (disambiguate if necessary);
- Register the device by clicking the “Z” button from the Zerynth Studio;
- Create a Virtual Machine for the device by clicking the “Z” button for the second time;
- Virtualize the device by clicking the “Z” button for the third time.
Note
No user intervention on the device is required for registration and virtualization process.
After virtualization, the DevKitC is ready to be programmed and the Zerynth scripts uploaded. Just Select the virtualized device from the “Device Management Toolbar” and click the dedicated “upload” button of Zerynth Studio.
Note
No user intervention on the device is required for the uplink process.
