Notes

Power pins: VDD (pins 10, 40, 60, 63) and GND (pins 9, 16, 39, 49, 59, 62) are distributed around the package for low-impedance power distribution.
Analog supply: VDD_0 (pin 18) and VSS_0 (pin 25) are dedicated analog power pins.
1.8V domain: GND_1V (pin 33) is ground for the 1.8V internal logic domain.
Crystal oscillator: XTAL_IN/XTAL_OUT (pins 61/1) and XI/XO (pins 50/51) provide dual crystal interface options.
Ethernet interface: MDI_TP/MDI_TN (pins 38/37) and MDI_RP/MDI_RN (pins 35/34) are the Ethernet MDI (Medium Dependent Interface) differential pairs.
Reset: RSTN (pin 26) is active-low reset.
LED outputs: LED_0 (pin 14) and LED_3 (pin 17) are dedicated LED control pins.
Regulator: REGIN (pin 13) and REG_OUT (pin 36) support on-chip voltage regulation.
