1.1 MCU Interface Signals
Symbol Type Pin No Description
nRST I 46 RESET ( Active LOW )
This pin is active Low input to initialize or re-initialize
W5200.
RESET should be held at least 2us after low assert, and
wait for at least 150ms after high de-assert in order for
PLL logic to be stable. Refer to RESET timing of “7
