ORCA® Series 4
Field-Programmable Gate Arrays
Programmable Features
s High-performance platform design.
— 0.13 µm seven-level metal technology.
— Internal performance of >250 MHz
(four logic levels).
— I/O performance of >416 MHz for all user I/Os.
— Over 1.5 million usable system gates.
— Meets multiple I/O interface standards.
— 1.5 V operation (30% less power than 1.8 V oper-
ation) translates to greater performance.
— Embedded block RAM (EBR) for onboard stor-
age and buffer needs.
— Built-in system components including an internal
system bus, eight PLLs, and microprocessor
interface.
s Traditional I/O selections.
— LVTTL and LVCMOS (3.3 V, 2.5 V, and 1.8 V)
I/Os.
— Per pin-selectable I/O clamping diodes provide
3.3 V PCI compliance.
— Individually programmable drive capability.
24 mA sink/12 mA source, 12 mA sink/6 mA
source, or 6 mA sink/3 mA source.
— Two slew rates supported (fast and slew-limited).
— Fast-capture input latch and input flip-flop (FF)/
latch for reduced input setup time and zero hold
time.
— Fast open-drain drive capability.
— Capability to register 3-state enable signal.
— Off-chip clock drive capability.
— Two-input function generator in output path.
s New programmable high-speed I/O.
— Single-ended: GTL, GTL+, PECL, SSTL3/2
(class I & II), HSTL (Class I, III, IV), zero-bus
turn-around (ZBT*), and double data rate (DDR).
— Double-ended: LDVS, bused-LVDS, LVPECL.
— Customer defined: Ability to substitute arbitrary
standard-cell I/O to meet fast moving standards.
s New capability to (de)multiplex I/O signals.
— New DDR on both input and output at rates up to
311 MHz (622 MHz effective rate).
— Used to implement emerging RapidIO† back-
plane interface specification.
— New 2x and 4x downlink and uplink capability per
I/O (i.e., 104 MHz internal to 416 MHz I/O).
s Enhanced twin-quad programmable function unit
(PFU).
— Eight 16-bit look-up tables (LUTs) per PFU.
— Nine user registers per PFU, one following each
LUT and organized to allow two nibbles to act
independently, plus one extra for arithmetic
carry/borrow operations.

† The usable gate counts range from a logic-only gate count to a gate count assuming 20% of the PFUs/SLICs being used as RAMs. The
logic-only gate count includes each PFU/SLIC (counted as 108 gates/PFU), including 12 gates per LUT/FF pair (eight per PFU), and
12 gates per SLIC/FF pair (one per PFU). Each of the four PIO groups are counted as 16 gates (three FFs, fast-capture latch, output logic,
CLK, and I/O buffers). PFUs used as RAM are counted at four gates per bit, with each PFU capable of implementing a 32 x 4 RAM (or
512 gates) per PFU. Embedded block RAM (EBR) is counted as four gates per bit plus each block has an additional 25k gates. 7k gates
are used for each PLL and 50k gates for the embedded system bus and microprocessor interface logic. Both the EBR and PLLs are con-
servatively utilized in the gate count calculations.
Note: Devices are not pinout compatible with ORCA Series 2/3.

ORCA Series 4 FPGAs
System Features (continued)
s Variable-size bused readback of configuration data capability with the built-in MPI and system bus.
s Internal, 3-state, bidirectional buses with simple control provided by the SLIC.
s Meets universal test and operations PHY interface for ATM (UTOPIA) Levels 1, 2, and 3. Also meets proposed
specifications for UTOPIA Level 4 for 10 Gbits/s interfaces.
s New clock routing structures for global and local clocking significantly increases speed and reduces skew
(<200 ps for OR4E4).
s New local clock routing structures allow creation of localized clock trees anywhere on the device.
s New DDR, QDR, and ZBT memory interfaces support the latest high-speed memory interfaces.
s New 2x/4x uplink and downlink I/O shift registers capabilities interface high-speed external I/Os to reduced inter-
nal logic speed.
s ORCA Foundry 2000 development system software. Supported by industry-standard CAE tools for design entry,
synthesis, simulation, and timing analysis.
