 +Some of the pins of the board are dedicated to a predefined function, some of the pins can be assigned a desired function. This assignment is made within the kernel of your operating system or dependent software drivers. Please check [[https://deepjava.org/runtime_library/start]]. The function of the PL pins are determined by the [[embedded_systems:zynq7000:microzed#configuration_files|Configuration Files]].

 Other necessary voltages (1.0V, 1.8V, 1.5V, 3.3V) are generated directly on the MicroZed board. Other necessary voltages (1.0V, 1.8V, 1.5V, 3.3V) are generated directly on the MicroZed board.
  
-The board will draw approximately 1.2A from the 5V supply. The current drawn on the IO-Bank supplies 3.3V_B34 and 3.3V_B35 is approximately the sum of all currents on the pins of the two banks.+The board will draw approximately 1.2A from the 5V supply.

-The electrical specification of the pins of the PL (FPGA part) are determined by IO-Bank supplies 3.3V_B34 and 3.3V_B35, see above. Pins of the MIO (bank 500) are of 3.3V type.+The electrical specification of the pins of the PL (FPGA part) are determined by IO-Bank supplies 3.3V_B34 and 3.3V_B35, see above. Pins of the MIO (bank 500) are of 3.3V type. Please be aware that all the flink devices such as PWM, FQD or UART have the same voltage levels as regular IO pins. \\ 
 +WARNING For interconnections to other devices such as processors or sensors you have to strictly adhere to the maximum voltage allowed. To be on the safe side we recommend using overvoltage protection with Zener diodes as used on our [[embedded_systems:experimentiersystem:expmicrozed|Adapter for Microzed Board]].
  
 ===== ADC ===== ===== ADC =====
-The MicroZed board doesn't incorporate an ADC. Please refer to [[embedded_systems:experimentiersystem:expmicrozed|Adapter für Microzed Board]] for connecting an external ADC128S102 (general purpose, 8 channels) or a AD7476 (1 channel, for IR distance sensors). The electrical specifications are determined by the external circuitry of the ADCs.+The Zynq7000 processor incorporates an ADC (XADC). In order to use this XADC, you have to choose the appropriate [[embedded_systems:zynq7000:microzed#configuration_files|Configuration File]]. When measuring unipolar analog input signals, the differential analog inputs (VP 
 +and VN) have an input range of 0V to 1.0V. The voltage on VP (measured with 
 +respect to VN) must always be positive. VN is typically connected to a local ground. Because the differential input range is from 0V to 1.0V (VP to VN), the maximum signal on VP is 1.0V.  
 +WARNING For interconnections to other devices such as sensors you have to strictly adhere to the maximum voltage allowed.

 +You can also connect an external ADC128S102 (general purpose, 8 channels) or a AD7476 (1 channel, for IR distance sensors). Please refer to [[embedded_systems:experimentiersystem:expmicrozed|Adapter for Microzed Board]] for proper connections. The electrical specifications are determined by the external circuitry of the ADCs.
