　　XMC4200数字电源控制板

　　The XMC4200 Digital Power Control Card is an evaluation board with the goal to help engineers in the learning and testing of digital power control applications. The board features a XMC4200 microcontroller based on ARM® Cortex™M4F core.

　　The dimensions of the board (50 mm height, 45 mm width to connector) allow the usage of this evaluation card into designs with high requirements on power density. In particular dimensions of XMC4200 Digital Power Control Card are suitable for 1U rack designs. The control card integrates an isolated on board debugger for plug and play experience. The isolated debugger part can be detached once the code is finalized.

　　This board has been developed with the collaboration of WürthElektronik whose passive components and mechanical components are used.

　　XMC4200数字电源控制板主要特性:

　　 Infineon XMC4200 (ARM® Cortex™-M4F-based) Microcontroller, 256 kByte on-chip Flash, LQFP64

　　 Connection to power board like Digital Power Explorer, via the power board connector including analog signals, PWM or serial interfaces

　　 5 LEDs

　　− 1 Power indicating LED - “Power OK” from power board side

　　− 2 User LEDs (P2.2, P2.6)

　　− 2 Debugger controller LEDs (DEBUG,COM)

　　 Isolated Debug options

　　− On-Board Debugger (SEGGER J-Link LITE) via USB connector

　　− ARM® Cortex™ 9 pin connector (1.27 mm pitch - double row) on non-isolated section. Isolation needs to be built between this connector and the computer side to avoid overvoltage in computer.

　　 Isolated Connectivity

　　− UART channel of On-Board Debugger (SEGGER J-Link LITE) via USB connector

　　 Power supply of MCU domain

　　− Via power board connector (12V). Converted to 3.3V with Infineon supply parts

　　 Power supply of isolated debug domain

　　− Via Debug USB connector
