3V3OUT
OUT
3.3 volt Output from the integrated L.D.O. regulator This pin should be decoupled
to GND using a 33nF ceramic capacitor in close proximity to the device pin. Its
prime purpose is to provide the internal 3.3V supply to the USB transceiver cell
and the RSTOUT# pin. A small amount of current (<= 5mA) can be drawn from
this pin to power external 3.3V logic if required.

VCC
PWR
+4.35 volt to +5.25 volt VCC to the device core, LDO and none-FIFO interface
pins.
13
VCCIO
PWR
+3.0 volt to +5.25 volt VCC to the FIFO interface pins 10..12, 14..16 and 18..25.
When interfacing with 3.3V external logic in a bus powered design connect
VCCIO to a 3.3V supply generated from the USB bus. When interfacing with
3.3V external logic in a self powered design connect VCCIO to the 3.3V supply
of the external logic. Otherwise connect to VCC to drive out at 5V CMOS level.

Note 1 : In Input Mode, these pins are pulled to VCCIO via internal 200K resistors. These can be programmed to
gently pull low during USB suspend ( PWREN# = “1” ) by setting this option in the EEPROM.
Note 2: During device reset, these pins are tri-state but pulled up to VCCIO via internal 200K resistors.
Note 3: During device reset, these pins are tri-state but pulled up to VCC via internal 200K resistors.
