Core supply voltage input. 20,31,42,56 VCCIO POWER Input +3.3V input. I/O interface power supply input. Failure to connect all VCCIO pins will result in failure of the device. 9 VPLL POWER Input +3.3V input. Internal PHY PLL power supply input. It is recommended that this supply is filtered using an LC filter. 4 VPHY POWER Input +3.3V Input. Internal USB PHY power supply input. Note that this cannot be connected directly to the USB supply. A +3.3V regulator must be used. It is recommended that this supply is filtered using an LC filter. 50 VREGIN POWER Input +3.3V Input. Integrated 1.8V voltage regulator input. 49 VREGOUT POWER Output +1.8V Output. Integrated voltage regulator output. Connect to VCORE with 3.3uF filter capacitor. 10 AGND POWER Input 0V Analog ground. 1,5,11,15, 25,35,47,51 GND POWER Input 0V Ground input. Table 3.2 Power and Ground for 64-pin QFN and LQFP package Pin No. Name Type Description 2 OSCI INPUT Oscillator input. 3 OSCO OUTPUT Oscillator output. 6 REF INPUT Current reference – connect via a 12KΩ resistor @ 1% to GND. 7 DM I/O USB Data Signal Minus. 8 DP I/O USB Data Signal Plus. 13 TEST INPUT IC test pin – for normal operation should be connected to GND. 14 RESET# INPUT Reset input (active low). |
