OR2C15A-3S304 - Brand New Lattice Semiconductor IC Chips
-
Description
The OR2C15A-3S304 is an electronic component model in the category of IC Chips. It belongs to the ORCA Series 2 series of SRAM-based FPGAs, which is an enhanced version of the ATT2C/2T architecture. The ORCA series features patented architectural enhancements that make functions faster and easier to design while conserving the use of PLCs and routing resources.
Specifications and features
- 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
- 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 pincount 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 ORCA Foundry Development 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 (VDD5)
-- 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 systems
Application Scenarios
The OR2C15A-3S304 can be used in various scenarios that require high-performance, low-power FPGA functionality. It is suitable for applications that require fast and efficient design functions while conserving the use of PLCs and routing resources. The enhanced features such as the ability to create larger RAM structures, cascadable nibble-wide data path capabilities, and hierarchical routing resources make it versatile for implementing 4-, 8-, 16-, and/or 32-bit bus structures, adders, subtractors, counters, multipliers, and comparators.
