ORCA Series 4 FPGAs  
Traditional I/O selections:  
LVTTL (3.3V) and LVCMOS (2.5 V and 1.8 V)  
I/Os.  
Introduction  
Built on the Series 4 recongurable embedded sys-  
tem-on-a-chip (SoC) architecture, Lattice introduces  
its new family of generic Field-Programmable Gate  
Arrays (FPGAs). The high-performance and highly  
versatile architecture brings a new dimension to  
bringing network system designs to market in less  
time than ever before. This new device family offers  
many new features and architectural enhancements  
not available in any earlier FPGA generations. Bring-  
ing together highly exible SRAM-based programma-  
ble logic, powerful system features, a rich hierarchy  
of routing and interconnect resources, and meeting  
multiple interface standards, the Series 4 FPGA  
accommodates the most complex and high-perfor-  
mance intellectual property (IP) network designs.  
— 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-lim-  
ited).  
— Fast-capture input latch and input ip-op  
(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.  
New programmable high-speed I/O:  
— Single-ended: GTL, GTL+, PECL, SSTL3/2  
(class I and II), HSTL (Class I, III, and IV), ZBT,  
and DDR.  
— Double-ended: LDVS, bused-LVDS, and  
LVPECL. Programmable (on/off) internal parallel  
termination (100 Ω) also supported for these  
I/Os.  
Programmable Features  
High-performance platform design:  
— 0.16 μm 7-level metal technology.  
— Internal performance of >250 MHz.  
— I/O performance of >420 MHz.  
— Meets multiple I/O interface standards.  
— 1.5 V operation (30% less power than 1.8 V  
operation) translates to greater performance.

* The embedded system bus and MPI are not included in the above gate counts. The System Gate ranges are derived from the following:  
minimum system gates assumes 100% of the PFUs are used for logic only (no PFU RAM) with 40% EBR usage and 2 PLLs. Maximum  
system gates assumes 80% of the PFUs are for logic, 20% are used for PFU RAM, with 80% EBR usage and 6 PLLs.  
Note: Devices are not pinout compatible with ORCA Series 2/3.
