ORSO42G5-1BM484C

The ORSO42G5-1BM484C is an ORCA® Series 4 Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor, designed for high-speed backplane and interdevice interfaces. Built on the Series 4 reconfigurable embedded SoC architecture, this device combines programmable FPGA fabric with integrated high-speed serial transceivers to address demanding SONET/SDH and non-SONET backplane applications.

This commercial-grade, surface-mount 484-BBGA package delivers a compact, high-density solution with 204 I/O pins, a wide supply voltage window, and on-chip embedded memory—making it suitable for designers implementing multi-gigabit backplane links, network termination, and high-throughput interconnects.

Key Features

• Series 4 Reconfigurable SoC Architecture  Integrates FPGA fabric with embedded system features to support complex protocol and interface logic.
• High-Speed SERDES  Four integrated SERDES channels supporting 0.6–2.7 Gbps per channel with built-in Clock and Data Recovery (CDR) for clockless high-speed links and simplified backplane clocking.
• Logic Capacity  Approximately 10,368 logic elements available in the FPGA fabric, delivered by 1,296 PFUs for flexible logic implementation.
• Embedded Memory  Approximately 113,664 bits of on-chip RAM to support buffering, packet processing and protocol logic.
• High I/O Count  204 user I/O pins for extensive connectivity to system logic, peripherals and backplane interfaces.
• System Gates  Up to 643,000 system gates for implementing complex data-paths, protocol stacks and custom logic.
• Package and Mounting  484-BBGA (484-FPBGA, 23×23 mm) surface-mount package for high-density board designs.
• Power and Temperature  Wide supply range from 1.425 V to 3.6 V and commercial operating temperature 0 °C to 70 °C for standard electronic environments.
• Compliance  RoHS compliant.

Typical Applications

• SONET/SDH Backplane Interfaces: Implement STS/STM framing, scrambling/descrambling and transport interfacing using the integrated SERDES and programmable logic.
• High-Speed Backplane Links: Provide multi-gigabit interboard or backplane connections with clock recovery to reduce backplane routing complexity.
• Network Termination and Line Cards: Terminate high-speed network links and bridge line cards to switch fabrics with aggregated bandwidth support.
• 10 Gbps Backplane Connections: Build high-throughput connections between line cards and switch fabric leveraging multiple SERDES channels and FPGA processing.

Unique Advantages

• Integrated High-Speed Transceivers: Four 0.6–2.7 Gbps SERDES channels with built-in CDR reduce external component count and simplify multi-gigabit link design.
• Compact, High-Density Package: 484-BBGA (23×23 mm) package packs 204 I/Os and significant logic capacity into a space-efficient footprint for dense board layouts.
• Flexible Power Envelope: Broad supply voltage support from 1.425 V to 3.6 V enables integration into diverse system power architectures.
• Significant Logic and Memory Resources: 10,368 logic elements and approximately 113.7 Kbits of embedded memory allow implementation of protocol stacks, buffering and custom processing on-chip.
• Commercial-Grade Reliability: Specified for 0 °C to 70 °C operation and RoHS compliance for standard commercial electronic applications.
