Detailed DescriptionThe MAX32625MBED board is general purpose in nature. However, the ability to access the majority of I/O signals allow for easy evaluation of the MAX32625. This sec-tion describes each major function or component on the MAX32625MBED.
Board PowerThe MAX32625MBED can be powered by either of the USB Micro-B connectors or an external source: VIN, V5.0, or V3.3.
HDK USB SupplyThe HDK USB connector provides access to the DAPLink circuitry. Power supplied from the HDK USB connector, CN2, is limited to 500mA. Only the HDK USB connector, CN2, powers the DAPLink circuitry. This supply is regu-lated to supply the HDK_V3.3 rail and is also connected to the V5.0 rail through a forward biased diode. From the V5.0 rail, it is regulated to supply V3.3.
MAX32625 USB Device Interface SupplyPower supplied from the MAX32625 USB device interface connector, CN1 is limited to 500mA. This supply is con-nected to the V5.0 rail through a forward biased diode. From the V5.0 rail, it is regulated to supply V3.3.

External Supply VINPower supplied from the VIN, J4 pin 8, is regulated to supply the V5.0 rail. The voltage input range for this input is 5V to 12V DC.
External Supplies V5.0 and V3.3Power supplied by V5.0, J4 pin 5, is connected directly to the V5.0 rail. Likewise, power supplied by V3.3, J4 pin 4, is connected directly to the V3.3 rail.
PushbuttonsTwo pushbuttons are available for application use: SW2 and SW3 are connected to port pins P2_2 and P2_3, respectively. Pushbuttons are normally open; therefore, provide a logic 0 when depressed. Firmware defines the action taken on switch closure. Pushbutton SW4 provides a power-on reset function for the MAX32625 by asserting the RSTN input.
USBThe MAX32625 provides an integrated USB2.0 Fullspeed interface (12Mbps). This interface is accessed through the USB Micro-B connector, CN1.
LEDsFour LEDs are available for application use: D4 (yel-low), D5 (red), D6 (blue), and D7 (green) are connected to MAX32620 GPIO pins P3_3, P3_0, P3_2, and P3_1, respectively. LED GPIOs should be configured as open drain due to 3.3V LED source voltages. An LED illumi-nates when the appropriate GPIO pin is driven low. One power supply status LED, D10, is connected to supply rail V5.0.
Prototyping AreaAn area for adding customer-specific circuitry is provided. This matrix is on 100mil spacing and is usable for solder or wire-wrap construction. Power and ground rails are conveniently located above and below this area.
