Lattice LFE3-17EA-7FN484C: A Comprehensive Technical Overview of ECP3-17 FPGA Features and Applications
The Lattice LFE3-17EA-7FN484C is a specific member of the Lattice ECP3™ FPGA family, renowned for its low-power, high-performance characteristics tailored for cost-sensitive and power-conscious applications. This device, packaged in a 7mm x 7mm, 484-ball fine-pitch BGA (FN484C), represents a balance of logic density, serial connectivity, and power efficiency that makes it a compelling choice for a wide range of modern electronic systems.
At its core, the "ECP3-17" designation signifies the Logic Elements (LEs) count, which stands at approximately 17,000. This provides a substantial fabric for implementing complex digital logic, state machines, and processing algorithms. Beyond raw logic, the architecture is rich with dedicated resources. It features embedded block RAM (EBR) for efficient on-chip data storage and FIFOs, alongside distributed RAM for more flexible, smaller memory structures. A critical component of the ECP3 family is its DSP block, which enables high-performance multiplication, accumulation, and other math-intensive operations crucial for signal processing.
One of the most significant features of the ECP3 family, and this device in particular, is its robust serial connectivity. The LFE3-17EA integrates multiple SERDES (Serializer/Deserializer) lanes capable of supporting major high-speed communication protocols. This includes:
PCI Express® (up to Gen1 x2), allowing the FPGA to act as a endpoint in systems requiring a standard peripheral interconnect.
Gigabit Ethernet, facilitating network-aware applications.
XAUI, for 10 Gigabit Ethernet and other high-bandwidth backplane interfaces.
This robust I/O capability is managed by Programmable sysI/O™ buffers, which support a vast array of single-ended and differential standards (LVCMOS, LVTTL, LVDS, LVPECL, etc.), providing immense flexibility in interfacing with other components in a system.
A hallmark of the ECP3 platform is its exceptionally low static power consumption. Built on a 65nm process technology with advanced design techniques, it is engineered for applications where power dissipation is a primary constraint. This makes it ideal for portable, battery-operated, or thermally sensitive equipment.
Applications of the LFE3-17EA-7FN484C are diverse, leveraging its mix of programmability, connectivity, and power efficiency:
Wireless Communications: Used in radio access networks for signal processing, interface bridging, and protocol management.
Video and Imaging Systems: Employed in video bridging, conversion, and transport for applications like medical imaging, professional broadcast, and digital signage, where processing multiple video streams is required.
Network Infrastructure: Functions as a co-processor or control plane manager in routers, switches, and security appliances, handling packet processing, traffic management, and interfacing.
Industrial and Automotive: Its reliability and interfacing capabilities suit it for industrial automation, motor control, and in-vehicle infotainment (IVI) systems.
ICGOOODFIND: The Lattice LFE3-17EA-7FN484C FPGA stands out as a highly integrated and power-optimized solution. It successfully bridges the gap between low-capacity CPLDs and high-end, power-hungry FPGAs. Its strengths lie not in raw processing power but in its balanced architecture, superior SERDES-based connectivity, and industry-leading low power consumption, making it a perfect fit for a vast array of serial connectivity, interface bridging, and control-oriented applications in the communications, video, and industrial markets.
