Pinout Descriptions
Table 1: Types of Pins on Spartan-3E FPGAs
I/Os with Lxxy_# are part of a differential output pair. ‘L’ indi-
cates differential output capability. The “xx” field is a
two-digit integer, unique to each bank that identifies a differ-
ential pin-pair. The ‘y’ field is either ‘P’ for the true signal or
‘N’ for the inverted signal in the differential pair. The ‘#’ field
is the I/O bank number.
Differential Pair Labeling
A pin supports differential standards if the pin is labeled in
the format “Lxxy_#”. The pin name suffix has the following

# = I/O bank number, an integer between 0 and 3.
Dedicated JTAG pin. Not available as a user-I/O pin. Every package has four
dedicated JTAG pins. These pins are powered by VCCAUX.
Dedicated ground pin. The number of GND pins depends on the package used.
All must be connected.
Dedicated auxiliary power supply pin. The number of VCCAUX pins depends on
the package used. All must be connected to +2.5V.
Dedicated internal core logic power supply pin. The number of VCCINT pins
depends on the package used. All must be connected to +1.2V.
Along with all the other VCCO pins in the same bank, this pin supplies power to
the output buffers within the I/O bank and sets the input threshold voltage for
some I/O standards.
This package pin is not connected in this specific device/package combination
but may be connected in larger devices in the same package.

a differential input to and a differential output from Bank 1.
"xx" is a two-digit integer, unique for each bank, that
identifies a differential pin-pair.
‘y’ is replaced by ‘P’ for the true signal or ‘N’ for the
inverted. These two pins form one differential pin-pair.
‘#’ is an integer, 0 through 3, indicating the associated
I/O bank.
‘L’ indicates that the pin is part of a differentiaL pair.
