DRA829 : a foil/matrix with power supply needed for each peripherals

Colombo Carlo

hello everybody , 

If possible  I would like to have a single foil/paper   where I can see summarized  Voltages needed  by every peripherals .

like  if using GPIO Bank )  you need  Vxx +Vxx etc 

is there anything like this available ?

thank you 

best regards

Carlo

    Carlo,

    The datasheet Table 4-1. Pin Attributes shows the power supply rail that is relevant for each functional signal on the device.  Columns in that table include Ball/Signal Name (e.g., mcu_rgmii1_tx_ctl), IO Voltage Value (1.8V/3.3V for Dual Voltage LVCMOS) and Power supply rail (VDDSHV2_MCU). 

    From that you can recognize what else is on VDDSHV2_MCU in which case all of the associated signals must operate at the same voltage level (either 1.8V or 3.3V) 

    I believe that gives the information you are looking for.  Is the issue that you wish it was in an xls or other format?

    Thanks,

    Kyle

    The PinMuxTool does include some simple power checks.  The user can assign the VDDSHV IO power banks to an voltage level (1.8 or 3.3).  Then when performing IO/pin assignments – you can select the ‘preferred’ voltage for the interface.  If the ‘preferred’ voltage does not match the assignment on the VDDSHV rail – it will give a warning.
