ORCA
®
Series 2
Field-Programmable Gate Arrays
Innovative, abundant, and hierarchical nibble-
oriented routing resources that allow automatic use of
internal gates for all device densities without sacrificing
performance
Upward bit stream compatible with the
ORCA
ATT2Cxx/
ATT2Txx series of devices
Pinout-compatible with new
ORCA
Series 3 FPGAs
TTL or CMOS input levels programmable per pin for the
OR2CxxA (5 V) devices
Individually programmable drive capability:
12 mA sink/6 mA source or 6 mA sink/3 mA source
Built-in boundary scan (
IEEE
*1149.1 JTAG) and
3-state all I/O pins, (TS_ALL) testability functions
Multiple configuration options, including simple, low pin-
count serial ROMs, and peripheral or JTAG modes for in-
system programming (ISP)
Full PCI bus compliance for all devices
Supported by industry-standard CAE tools for design
entry, synthesis, and simulation with ispLEVER Develop-
ment System support (for back-end implementation)
New, added features (OR2TxxB) have:
— More I/O per package than the OR2TxxA family
— No dedicated 5 V supply (V
DD
5)
— Faster configuration speed (40 MHz)
— Pin selectable I/O clamping diodes provide 5V or 3.3V
PCI compliance and 5V tolerance
— Full PCI bus compliance in both 5V and 3.3V PCI sys-
tems
High-performance, cost-effective, low-power
0.35 µm CMOS technology (OR2CxxA), 0.3 µm CMOS
technology (OR2TxxA), and 0.25 µm CMOS technology
(OR2TxxB), (four-input look-up table (LUT) delay less
than 1.0 ns with -8 speed grade)
High density (up to 43,200 usable, logic-only gates; or
99,400 gates including RAM)
Up to 480 user I/Os (OR2TxxA and OR2TxxB I/Os are
5 V tolerant to allow interconnection to both 3.3 V and
5 V devices, selectable on a per-pin basis)
Four 16-bit look-up tables and four latches/flip-flops per
PFU, nibble-oriented for implementing 4-, 8-, 16-, and/or
32-bit (or wider) bus structures
Eight 3-state buffers per PFU for on-chip bus structures
Fast, on-chip user SRAM has features to simplify RAM
design and increase RAM speed:
— Asynchronous single port: 64 bits/PFU
— Synchronous single port: 64 bits/PFU
— Synchronous dual port: 32 bits/PFU
Improved ability to combine PFUs to create larger RAM
structures using write-port enable and 3-state buffers
Fast, dense multipliers can be created with the multiplier
mode (4 x 1 multiplier/PFU):
— 8 x 8 multiplier requires only 16 PFUs
— 30% increase in speed
Flip-flop/latch options to allow programmable priority of
synchronous set/reset vs. clock enable
Enhanced cascadable nibble-wide data path
capabilities for adders, subtractors, counters, multipliers,
and comparators including internal fast-carry operation

* The first number in the usable gates column assumes 48 gates per PFU (12 gates per four-input LUT/FF pair) for logic-only designs. The
second number assumes 30% of a design is RAM. PFUs used as RAM are counted at four gates per bit, with each PFU capable of
implementing a 16 x 4 RAM (or 256 gates) per PFU.
