Stresses above the absolute maximum rating may cause permanent damage to the device. Extended operation at the
maximum levels may degrade performance and affect reliability.
Overshoot/Undershoot limits: For AC signals, the input signal may undershoot during transitions to -1.0 V for no longer
than 10% of the period or 11 ns whichever is smaller. Current during the transition must not exceed 95 mA. For AC
signals, the input signal may overshoot during transitions to V

1.5 Power-Up/Down Sequence. All device I/Os are tri-stated during power-up until normal device operating conditions are
reached, which is when I/Os enter user mode. V
CCA
, V
CCI
, and V
CCDA
can be powered up or powered down in any sequence.
All device I/Os are hot-swap compliant with cold-sparing support (except PCI).
1.5.1 R-cells and I/O Registers. On a chip-wide basis at power-up, all R-cells and I/O Registers are either cleared or preset
by driving the global clear (GCLR) and global preset (GPSET) inputs (see Figure 3). Default setting is to clear all registers
(GCLR = 0 and GPSET =1) at device power-up.
1.6 Device Logic Configuration.
1.6.1 Core array logics include two types of logic modules: the register cell (R-cell) and the combinatorial cell (C-cell). C-cell
contains carry logic for efficient arithmetic functions. R-cell appears as a single D-type flip-flop to user, but is implemented in
silicon with triple module redundancy (TMR) to improve SEU performance. Each TMR R-cell consists of three master-slave
latch pairs, each with asynchronous self-correcting feedback paths. Output of the TMR R-cell is the result of the majority voting
of the outputs of the three flip flops in the TMR R-cells. Logic modules are grouped as SuperCluster, each SuperCluster has
two Clusters, and each Cluster includes two C-cells, one R-cell, two transmit (TX) and two receive (RX) routing buffers. Each
SuperCluster also includes an independent buffer module. On the chip level, SuperClusters are organized into core tiles, which
are arrayed to build up the full chip. There are four core tiles in this device and each tile has 176 SuperClusters, resulting in a
total of 1,408 R-cells and 2,816 C-cells in the device.
1.6.2 Clock Resources are available with two types of global clock networks throughout the chip. There are four dedicated
hardwired clock input pins (HCLKA/B/C/D) that will directly drive all the sequential modules (R-cells, I/O registers, embedded
RAM/FIFO). There are also four global clock input pins (CLKE/F/G/H) for routed clock distribution networks that are buffered
prior to clocking the R-cells; the routed clocks can also be programmed to drive S0, S1, PSET, and CLR of a register, or as the
inputs of any C-cell. Input levels for all clocks are compatible with all supported I/O standards (there is a P/N pin pair to
support differential I/O standards). All clock networks have been hardened to improve SEU performance.
1.6.3 Embedded RAM is available as a global resource. There are three 4,608-bit RAM blocks in each tile, with a total of
55,296 bits in the device. Each 4,608-bit RAM block can be organized as 128x36, 256x18, 512x9, 1,024x4, 2,048x2, or 4,096
x1 (Depth x Word in bits), and are cascadable to create larger memory sizes. Each RAM block has independent read and write
ports, which enables simultaneous read and write operations; it also contains its own embedded FIFO controller, allowing the
RAM blocks to be configured as either RAM or FIFO. SRAM structures are susceptible to radiation upsets, to achieve high
level SEU performance; manufacturer has provided an IP core to enhance the SEU tolerance of the embedded RAM blocks by
mitigating upsets with Error Detection and Correction (EDAC) and background memory-refresher (or scrubber). Registers in
the FIFO controller are not hardened for radiation, so when high SEU tolerance is required, the FIFO control unit should be
implemented with core logic. Note: Simultaneous read and write operations to the same address is not supported.

Each I/O provides programmable slew rates, drive strength, and weak pull-up and pull-down circuits (in the order of 10k), it
also includes three registers (input (InReg), output (OutReg), and enable (EnReg)). I/Os are organized into eight banks (0-7)
with two banks per device side. Each I/O bank has a common V
CCI
and a common reference-voltage bus. For each I/O bank,
multiple I/O standards may be selected, however, all I/O standards used in the same I/O bank shall have the same V
CCI
value
and the same V
REF
value (when required). V
REF
pin is not pre-defined, any user I/O in the bank can be selected to be a V
REF
.
1.6.5 Routing Resource provides hierarchical routing structure that ties the logic modules, the embedded memory block,
and the I/O modules together. User designs can be implemented with manufacturer’s Designer software (see 6.7 herein),
which includes a Timer that supports timing-driven place-and-route; plus SmartPower for power estimation; PinEditor and I/O
Attribute Editor for I/O assignments and I/O attributes; Netlist Viewer and ChipPlanner for design implementation. Additionally,
Libero IDE allows users to integrate both schematic and HDL synthesis into a single flow and verify the entire design in a single
environment (see 6.7 herein).
1.6.6 Calculation for Junction Temperature. The temperature variable in the manufacturer’s Designer software refers to the
junction temperature, not the ambient, case, or board temperature. The operating temperature at case (T
C
) can be calculated
with
JC
=
(
T
J
– T
C
)
P; and the operating temperature at board interface (T
B
) for case outline Z can be calculated with
JB
=
(
T
J
– T
B
)
P. P is the device power consumption, which differs among user designs. Power usage can be determined by
logic cell utilization; clock usage and frequency; input cell utilization and frequency; output cell utilization, V
CCI
level and output
frequency; and static power consumption. The manufacturer’s software tool will assist users on power estimation.
