ORSO82G5-1FN680I

The ORSO82G5-1FN680I is an ORCA® Series 4 reconfigurable embedded System-on-a-Chip FPGA targeted at high-speed backplane and interdevice communication. Built on Lattice’s Series 4 architecture, this device integrates FPGA fabric with multi‑Gbps serial transceivers to address SONET and other high-speed backplane interfaces.

Key value comes from its integrated SERDES channels with clock recovery, substantial on‑chip logic and memory resources, and a high pin‑count 680‑FBGA package—delivering a compact, industrial‑grade solution for demanding board and backplane designs.

Key Features

• Series 4 FPGA Architecture – 1,296 programmable functional units providing 10,368 logic elements and an FPGA system gate range up to 643,000 gates for complex logic integration.
• High‑Speed Serial Transceivers – Eight integrated SERDES channels supporting 0.6 to 2.7 Gbps with built‑in Clock and Data Recovery (CDR); aggregate bandwidth above 20 Gbps for multi‑lane backplane links.
• Embedded Memory – Approximately 0.114 Mbits (113,664 bits) of total on‑chip RAM plus two 144K‑bit RAM blocks in the embedded core that are accessible by FPGA logic for buffering and packet processing.
• I/O and Package – Up to 372 user I/O in a 680‑FBGA (35 × 35 mm) package; surface‑mount package supports high‑density board designs.
• Power and Temperature – Flexible supply range from 1.425 V to 3.6 V and industrial operating temperature range of −40 °C to 85 °C for deployment in demanding environments.
• System Integration – Embedded features for SONET data handling (scrambling/descrambling, framing and limited TOH) and compatibility with related ORT devices; intended for configurable backplane termination and protocol handling.
• Regulatory – RoHS compliant.

Typical Applications

• SONET/SDH Backplane Interfaces – Ideal for terminating and processing SONET streams with integrated scrambling, framing and clock recovery across multiple high‑speed channels.
• High‑Speed Backplane Links – Use the multi‑Gbps SERDES and CDR to create clockless, high‑bandwidth connections between line cards and switch fabrics or between boards.
• Line Card to Switch Fabric Connectivity – Supports work and protection connections using multiple SERDES lanes to deliver aggregated bandwidth for fabric interfacing.
• Custom Packet and Cell Processing – Embedded RAM and FPGA fabric enable framing, cell processing and protocol access logic for proprietary or standardized data formats.

Unique Advantages

• Integrated High‑Speed Transceivers: Eight built‑in 0.6–2.7 Gbps SERDES channels with CDR reduce external PHY requirements and simplify backplane design.
• Substantial FPGA Capacity: 10,368 logic elements and up to ~643k system gates support complex custom logic and protocol offload on a single device.
• Accessible Embedded Memory: Approximately 0.114 Mbits of embedded RAM plus two 144K‑bit core RAM blocks provide on‑chip buffering and packet storage.
• High I/O Count in Compact Package: 372 user I/O in a 680‑FBGA (35 × 35 mm) gives dense connectivity while keeping board area compact.
• Industrial‑Grade Operating Range: −40 °C to 85 °C and broad supply range (1.425 V–3.6 V) enable reliable operation across typical industrial environments.
• Design Ecosystem Support: Documented compatibility with Lattice development tools and the FPSC design kit facilitates integration and development workflows.
