3.3v darlington array
Attached the snapshot of ULN280x datasheet. I think I need to use ULN2801 (without base series resistor) as my GPIOs are 3.3V Vdd logic and can source only 2 ma from each GPIO. The Voh and Vol for the GPIOs are 2.66 min and 0.66 max respectively. Will my MCU GPIOs able to...
pcb track
If trace impedance is higher than the impedance of the driver, a series termination resistor is needed at the output f the driver. How do we solve if the impedance of the driver is more than the impedance of the trace?
Besides other parameters does the material used for PCB...
Hi,
I am designing with LPC3131 MCU from NXP and I don't require several in-built peripheral devices like ADC, USB etc. and they have exclusive power pins as well as software controlled enable/disable.
Shall I simply leave their power pins open or do I need to connect them and disable these...
Board design help
I am trying to design a prototyping board for LPC31xx microcontroller based on the reference schematic given by NXP in the pdf link below. Could anyone help me figure out what SHT stands for and significance of those numbers folowing SHT...
