ORT42G5-2BM484I

The ORT42G5-2BM484I is an ORCA® 4 Field Programmable Gate Array (FPGA) device from Lattice Semiconductor designed for high-speed serial backplane and board-level interconnect applications. Built on the Series 4 reconfigurable embedded System-on-a-Chip architecture, the ORT42G5 integrates programmable FPGA logic with multi-channel SERDES transceivers and on-chip memory to address networking, communications, and high‑speed data transport use cases.

This industrial‑grade device combines high I/O density, integrated serial interfaces, and a compact 484‑BBGA package to deliver a configurable platform for XAUI, Fibre Channel and other backplane or inter‑device link implementations.

Key Features

• Programmable Logic  10,368 logic elements providing flexible FPGA fabric for custom logic, protocol handling and data processing.
• PFU Array  1,296 programmable function units (PFUs) organized for scalable logic and routing resources.
• Embedded Memory  Approximately 0.114 Mbits of on‑chip RAM (113,664 bits) for packet buffering, FIFOs and intermediate storage.
• SERDES Transceivers  Four SERDES channels supporting serial data links (device family supports up to 3.7 Gbps per channel as described in the ORCA series datasheet) with built‑in Rx Clock and Data Recovery (CDR) and transmitter preemphasis.
• Protocol Support  Embedded support in the ORCA series for 8b/10b encoding/decoding and link state machines suitable for XAUI and Fibre Channel link implementations.
• I/O Density  204 user I/O pins to accommodate high‑pin‑count backplane and board‑level interfacing requirements.
• System Capacity  643,000 gates of system logic capacity for complex control, bridging and data path tasks.
• Power and Temperature  Voltage supply range from 1.425 V to 3.6 V and industrial operating temperature range of −40 °C to 85 °C.
• Package  484‑BBGA package (supplier device package: 484‑FPBGA, 23×23) for a compact, high‑density footprint.
• Environmental Compliance  RoHS compliant.

Typical Applications

• High‑speed backplane interconnects  Implement clockless high‑speed links and multi‑channel alignment for board‑to‑board or backplane data transport.
• 10G Ethernet / XAUI bridging  Use integrated SERDES and 8b/10b encoding/decoding to implement XAUI interfaces and configurable back‑end logic such as XGMII bridging.
• Fibre Channel link endpoints  Leverage embedded link state machines and protocol support to build Fibre Channel interfaces and link termination functions.
• Network line cards and switch fabric interfaces  Provide multi‑channel transceiver connectivity and FPGA packet processing for line card to fabric links and protection paths.

Unique Advantages

• Integrated SERDES and FPGA fabric: Combines high‑speed serial transceivers with 10,368 logic elements to reduce external components and simplify board design.
• High I/O count in a compact package: 204 user I/Os in a 484‑BBGA (23×23) footprint supports dense routing and high‑pin designs while conserving PCB area.
• Industrial operating range: Specified for −40 °C to 85 °C and a flexible 1.425 V–3.6 V supply window to meet typical industrial system requirements.
• On‑chip memory for buffering: Approximately 0.114 Mbits of embedded RAM enables local packet buffering, alignment FIFOs and temporary storage without external memory.
• Protocol and link support: Built‑in 8b/10b encoding/decoding and link state machines streamline implementation of Ethernet and Fibre Channel links.
• Environmental compliance: RoHS compliant to support regulatory and manufacturing requirements.
