INPUT

I/O

Description

Oscillator input.

Oscillator output.

Current reference – connect via a 12KΩ resistor @ 1% to GND.

USB Data Signal Minus.

I/O

USB Data Signal Plus.

TEST

RESET#

INPUT

IC test pin – for normal operation must be connected to GND.

Reset input (active low).

USB Power Save input. This is an EEPROM configurable option which

is set using a ’Suspend on DBus7 Low’ bit on FT_PROG . This option

is available when the FT232H is on 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#

INPUT

PWRSAV# = 0 : FT232H forced into SUSPEND mode.

PWRSAV# can be connected to VBUS of the USB connector (via a

39KΩ resistor). When this input goes high, then it indicates to the

FT232H that it is connected to a host PC. When the host or hub is

powered down then the FT232H is held in SUSPEND mode.
