Overview of ORT82G5-1FN680C – ORCA® 4 FPGA, 680‑BBGA, 10,368 logic elements
The ORT82G5-1FN680C is an ORCA® Series 4 field programmable gate array (FPSC/FPGA) IC from Lattice Semiconductor designed for high-speed serial backplane and board-level interfaces. Built on the Series 4 reconfigurable embedded SoC architecture, this device integrates eight SERDES channels and programmable FPGA logic to support demanding serial communications and interface bridge functions.
This commercial‑grade device provides 10,368 logic elements, approximately 0.11 Mbits of embedded memory, 372 user I/Os and a 680‑BBGA package, making it suitable for high-density I/O and multi‑channel serial designs where compact packaging and configurable logic are required.
Key Features
- Programmable Logic Capacity — 10,368 logic elements for implementing custom logic, protocol handling and glue logic.
- Programmable Functional Units (PFUs) — 1,296 PFUs (rows × columns architecture) for flexible mapping of logic and memory resources.
- Embedded Memory — Approximately 113,664 bits (~0.11 Mbits) of on-chip RAM for buffering, FIFOs and local data storage.
- High‑Speed SERDES — Eight SERDES channels (ORT82G5 family) with per-channel data rates up to 3.7 Gbps and support for backplane transmission across FR‑4 distances as described in the ORCA family datasheet.
- Protocol Support — Embedded 8b/10b encoding/decoding and link state machines for 10 Gigabit Ethernet and Fibre Channel applications (as implemented in the ORCA ORT42G5/ORT82G5 family).
- I/O Density — 372 user I/Os to interface with parallel and serial peripherals, front‑panel connectors, or internal boards.
- Gate Equivalent — Approximately 643,000 system gates reported for design sizing and comparison.
- Power and Voltage — Flexible supply voltage range from 1.425 V to 3.6 V to accommodate a range of board power architectures.
- Package and Mounting — 680‑BBGA (supplier device package: 680‑FPBGA, 35 × 35 mm) in a surface‑mount format for high‑density board layouts.
- Operating Conditions — Commercial operating temperature range of 0 °C to 70 °C and RoHS compliant.
Typical Applications
- High‑Speed Backplane Interfaces — Multi‑channel SERDES and embedded link logic enable implementation of XAUI, Fibre Channel and other backplane serial links.
- 10 Gigabit Ethernet Bridging — Use the programmable logic and 8b/10b encoding/decoding to build XAUI to XGMII bridges and other 10 GbE front/back‑end interfaces.
- Network Line Cards and Switch Fabric — Eight SERDES channels and high I/O count support line card to fabric interconnects with work/protection link architectures.
- Board‑level High‑speed Data Transfer — Implement clockless high‑speed interfaces between devices on a board or across a backplane with built‑in Rx clock and data recovery.
Unique Advantages
- Multi‑channel serial throughput: Eight SERDES channels rated up to 3.7 Gbps per channel provide parallel high‑speed lanes for aggregate bandwidth and redundancy.
- Balanced logic and memory: 10,368 logic elements combined with ~0.11 Mbits of embedded RAM offer a practical balance for protocol engines, buffering and packet handling.
- High I/O count: 372 user I/Os reduce the need for additional interface devices and simplify board partitioning for complex systems.
- Compact BGA footprint: 680‑BBGA (35 × 35 mm) delivers high integration in a surface‑mount package suitable for dense board designs.
- Flexible supply range: Support for 1.425 V to 3.6 V supplies eases integration with a variety of board power schemes.
- Standards‑oriented features: Built‑in 8b/10b encoding/decoding and link state machines streamline implementation of 10 GbE and Fibre Channel links.
