PRODUCTION DATA
The XIO2001 requires both 1.5-V and 3.3-V digital power. The 1.5-V pins are named VDD_15. These pins supply power to the digital core. The 1.5-V core allows for a significant reduction in both power consumption and logic switching noise. The 3.3-V pins are named VDD_33 and supply power to most of the input and output cells. Both the VDD_15 and VDD_33 supplies must have 0.1-μF bypass capacitors to VSS (ground) in order for proper operation. The recommendation is one capacitor for each power pin. When placing and connecting all bypass capacitors, high-speed board design rules must be followed.
