Pin Descriptions
This section describes the pins found on the Series 4 FPGAs. Any pin not described in this table is a user-program-
mable I/O. During conguration, the user-programmable I/Os are 3-stated with an internal pull-up resistor. If any pin
is not used (or not bonded to a package pin), it is also 3-stated with an internal pull-up resistor after conguration.
The pin descriptions in Table and throughout this data sheet show active-low signals with an overscore. The pack-
age pinout tables that follow, show this as a signal ending with _N. For example LDC and LDC_N are equivalent.

I/O
Description
Dedicated Pins
VDD33
— 3.3V positive power supply. This power supply is used for 3.3 V conguration RAMs and internal
PLLs. When using PLLs, this power supply should be well isolated from all other power supplies
on the board for proper operation.
VDD
15
— 1.5 V positive power supply for internal logic.
VDDIO
— Positive power supply used by I/O banks.
VSS
— Ground.
PTEMP
I
Temperature sensing diode pin. Dedicated input.
RESET
I
During conguration, RESET forces the restart of conguration and a pull-up is enabled. After
conguration, RESET can be used as a general FPGA input or as a direct input, which causes
all PLC latches/FFs to be asynchronously set/reset.
CCLK
O
In the master and asynchronous peripheral modes, CCLK is an output which strobes congura-
tion data in.
I
In the slave or readback after conguration, CCLK is input synchronous with the data on DIN or
D[7:0]. CCLK is an output for daisy-chain operation when the lead device is in master, periph-
eral, or system bus modes.
DONE
I
As an input, a low level on DONE delays FPGA start-up after conguration.*
O
As an active-high, open-drain output, a high level on this signal indicates that conguration is
complete. DONE has an optional pull-up resistor.
PRGM
I
PRGM
is an active-low input that forces the restart of conguration and resets the boundary-
scan circuitry. This pin always has an active pull-up.
RD_CFG
I
This pin must be held high during device initialization until the INIT pin goes high. This pin
always has an active pull-up. During conguration, RD_CFG is an active-low input that activates
the TS_ALL function and 3-states all of the I/O.
After conguration, RD_CFG can be selected
(via a bit stream option) to activate the TS_ALL function as described above, or, if readback is
enabled via a bit stream option, a high-to-low transition on RD_CFG will initiate readback of the
conguration data, including PFU output states, starting with frame address 0.
RD_DATA/TDO
O
RD_DATA/TDO is a dual-function pin. If used for readback, RD_DATA provides conguration
data out. If used in boundary-scan, TDO is test data out.
CFG_IRQ/MPI_IRQ
O
During JTAG, slave, master, and asynchronous peripheral conguration assertion on this
CFG_IRQ
(active-low) indicates an error or errors for block RAM or FPSC initialization.
MPI
active-low interrupt request output, when the MPI is used.
