3.3 Signal Description
The operation of the following FT232H pins are the same regardless of the configured mode:-
Pin No.
Name
Type
Description
40
**
VREGIN
POWER
input
+5.0V or 3V3 power supply input.
37
VCCA
POWER
output
+1.8V output. Should not be used.
38
VCORE
POWER
output
+1.8V output. Should not be used.
39
**
VCCD
POWER
output or
input
+3.3V output or input.
12, 24, 46
VCCIO
POWER
input
+3.3V input. I/O interface power supply input
8
VPLL
POWER
Input
+3.3V input. Internal PLL power supply input. It is
recommended that this supply is filtered using an LC filter.
(See figure 6.1)
3
VPHY
POWER
Input
+3.3V input. Internal USB PHY power supply input. Note that
this cannot be connected directly to the USB supply. A +3.3V
regulator must be used. It is recommended that this supply is
filtered using an LC filter.(See figure 6.1)

AGND
POWER
Input
0V Ground input.
10,11,22,23,35,36,47,48
GND
POWER
Input
0V Ground input.
Table 3.1 Power and Ground
** If pin 40 (VREGIN) is +5.0V, pin 39 becomes an output and If pin 40 (VREGIN) is 3V3 pin 39 becomes
an input.
