Description

VCCIO
PWR
+1.8V to +5.25V supply to the FIFO Interface group pins (1...3, 5, 6, 9...14, 22,
23). In USB bus powered designs connect this pin to 3V3OUT pin to drive out at
+3.3V levels, or connect to VCC to drive out at 5V CMOS level. This pin can also
be supplied with an external +1.8V to +2.8V supply in order to drive outputs at
lower levels. It should be noted that in this case this supply should originate from
the same source as the supply to VCC. This means that in bus powered designs a
regulator which is supplied by the +5V on the USB bus should be used.

GND
PWR
Device ground supply pins

3V3OUT
Output
+3.3V output from integrated LDO regulator. This pin should be decoupled to
ground using a 100nF capacitor. The main use of this pin is to provide the internal
+3.3V supply to the USB transceiver cell and the internal 1.5kΩ pull up resistor on
USBDP. Up to 50mA can be drawn from this pin to power external logic if
required. This pin can also be used to supply the VCCIO pin.

VCC
PWR
+3.3V to +5.25V supply to the device core. (see Note 1)
25
AGND
PWR
Device analogue ground supply for internal clock multiplier

RESET#
Input
Active low reset pin. This can be used by an external device to reset the
FT245R. If not required can be left unconnected, or pulled up to VCC.
26
TEST
Input
Puts the device into IC test mode. Must be tied to GND for normal
operation, otherwise the device will appear to fail.
27
OSCI
Input
Input 12MHz Oscillator Cell. Optional – Can be left unconnected for
normal operation. (see Note 2)
28
OSCO
Output
Output from 12MHZ Oscillator Cell. Optional – Can be left unconnected
for normal operation if internal Oscillator is used. (see Note 2)
