Description
USB2.0 data pin Data positive pin terminal.
USB2.0 data pin Data negative pin terminal.
Internal voltage reference input. Requires external resistor to GND,
(12.1k-ohm +/- 0.1 %).
Crystal Oscillator Output (12/30 MHz). See XTALSEL pin description.
Crystal Oscillator Input (12/30 MHz).
USB1.1 data in Data positive pin terminal. Connects to DPA via external
series resistor (39 ohm +/- 0.1%).
USB1.1 data in Data negative pin terminal. Connects to DMA via exter-
nal series resistor (39 ohm +/- 0.1%).
Internal reference current input. Requires external resistor (1.5 k-ohm
+/- 0.1%) to AVCC (Analog 3.3V Power).
Hardware Reset to the Chip (pull-down). Active low signal. Requires
external capacitor (0.1uF) to 3.3V Power Supply.
Address bank select (pull-down). This is reflected in the INTIN transfers
for assigning the MAC address.
Mode selection bit (pull-up). One of the four mode pins used for select-
ing the device operation mode.
Mode selection bit (pull-up). One of the four mode pins used for select-
ing the device operation mode.
Mode selection bit (pull-up). One of the four mode pins used for select-
ing the device operation mode.
Mode selection bit (pull-up). One of the four mode pins used for select-
ing the device operation mode.
USB1.1 data in Data positive pin terminal, connects to DPB via external
series resistor (39 ohm +/- 0.1%).
USB1.1 data in Data negative pin terminal, connects to DMB via exter-
nal series resistor (39 ohm +/- 0.1%).
“0”-> Software selects “A” pair of addresses.
“1”-> Software selects “B” pair of addresses.
