    helo,

    how to draw schematic of MSP430F5505IRGZ...(Like how many pull up resistor n pull down resistor,how many coupling n decoupling capacitor etc etc)...is it possible to know evrything from its datasheet?please help.

    regards..

    1x 100nF decoupling for each power supply pin (Vcc).
    Add pullups and pulldowns to taste, it is better to have all inputs in a known state when nothing is connected.

    N what shoud be connected to reset pin??

    what should be connected to the reset pin if it is mentioned "reset input active low"

    Well do you plan to use the reset pin for reset or do you just want to tie to a inactive level? If you do not want to use it. Your micro may have an option to tie it to a high level internal

    Active low is the same as the micro will enter reset mode. Then a "low" signal is connected to the pin i.e ground. To prevent this tie it to the VCC pin via some resistor Any value in the range 1Kohm to 10Kohm should work fine
