Type
EEPROM – Chip Select. Tri-State during device reset.
Clock signal to EEPROM. Tri-State during device reset. When not in reset, this
outputs the EEPROM clock.
EEPROM – Data I/O Connect directly to Data-In of the EEPROM and to Data-Out
of the EEPROM via a 2.2K resistor. Also, pull Data-Out of the EEPROM to VCC via
a 10K resistor for correct operation. Tri-State during device reset.
Oscillator input.
Oscillator output.
Current reference – connect via a 12KΩ resistor @ 1% to GND.
USB Data Signal Minus.
USB Data Signal Plus.
IC test pin – for normal operation should be connected to GND.
Reset input (active low).
Active low power-enable output.
PWREN# = 0: Normal operation.
PWREN# =1 : USB SUSPEND mode or device has not been configured.
This can be used by external circuitry to power down logic when device
is in USB suspend or has not been configured.
Active low when USB is in suspend mode.
USB Power Save input. This is an EEPROM configurable option used
when the FT2232H is used in a self powered mode and is used to
prevent forcing current down the USB lines when the host or hub is
powered off.
PWRSAV# = 1 : Normal Operation
PWRSAV# = 0 : FT2232H forced into SUSPEND mode.
PWRSAV# can be connected to GND (via a 10KΩ resistor) and another
resistor (e.g. 4K7) connected to the VBUS of the USB connector. When
this input goes high, then it indicates to the FT2232H that it is
connected to a host PC. When the host or hub is powered down then
the FT2232H is held in SUSPEND mode.
