Though you might want to take into account anything else connected as an output device (LEDs or such); though with your budget of 200mA, and only ~120mA used, you still have some headroom... WebJun 13, 2024 · Basically, this problem is related to mapping the toplevel IO's of either verilog or vhdl to the unused pins of a Xilinx FPGA. Xilinx's old FPGA compiler, "ISE", used to give you a report of the "pin assignments" that the compiler was able to map to the bitfile, once the compiler was finished generating the FPGA binary file for upload.

Looks like about 4mA for most pins, 8mA for some, and about 15mA for some, under special "relaxed" circumstances (voltage allowed to be 0.6V off of idea rather than 0.4V.) See the datasheet, section: 45.2 DC Characteristics, particularly "source current" and "sink current." The 130mA per-chip limit is in addition ... WebMay 17, 2024 · IO pin low state at startup? Hi, i have some problem with IO pin that i want to have at low output level as soon as possible. I am doing that at start of program clearing output pin to '0': PORTxCLR, and then clearing proper TRISxCLR pin. But i have always short pulse of VDD between powerup and starting software. country name starting with s
