LFE3-70EA-8LFN1156I

The LFE3-70EA-8LFN1156I is an ECP3 Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor Corporation designed for industrial-grade embedded systems. It combines a mid-to-high logic density fabric with substantial on-chip memory and a large I/O complement to address applications that require high integration and flexible I/O interfacing.

With approximately 67,000 logic elements, roughly 4.5 Mbits of embedded memory, and up to 490 I/Os, this device is suited for designs where logic capacity, memory and I/O density must be balanced with compact packaging and industrial temperature operation.

Key Features

• Core Logic  Approximately 67,000 logic elements provide substantial programmable logic capacity for complex digital functions and custom hardware acceleration.
• Embedded Memory  Approximately 4.5 Mbits of on-chip RAM enable local buffering, lookup tables and state storage without immediate reliance on external memory.
• I/O Density  Up to 490 I/Os accommodate extensive peripheral interfacing, multi-channel connectivity and high-pin-count system requirements.
• Power Supply Range  Operates from a supply range of 1.14 V to 1.26 V, allowing designers to plan power delivery and sequencing around a defined core voltage.
• Package and Mounting  Supplied in a 1156-FPBGA (35×35) / 1156-BBGA package for surface-mount assembly, offering a compact footprint for high-density boards.
• Temperature and Grade  Industrial grade device rated for operation from −40 °C to 100 °C, suitable for harsh-environment deployments.
• Environmental Compliance  RoHS compliant to support lead-free assembly and regulatory requirements.

Typical Applications

• Industrial Control Systems  Large logic capacity and industrial temperature rating enable deterministic control, motor control logic and custom automation interfaces.
• Communications and Networking  High I/O count and on-chip memory support packet processing, protocol bridging and interface aggregation in networking equipment.
• High-Density I/O Bridging  Use the abundant I/Os to implement multi-channel sensor aggregation, IO expansion, or protocol conversion between subsystems.
• Embedded System Integration  Combine logic, memory and I/O to offload processing tasks, accelerate custom algorithms, or implement bespoke peripherals for embedded platforms.

Unique Advantages

• High Logic Capacity: Approximately 67,000 logic elements allow implementation of complex state machines, custom accelerators and sizable FPGA-based subsystems.
• Substantial On-Chip Memory: Roughly 4.5 Mbits of embedded RAM reduce dependence on external memory for buffering and fast data access.
• Extensive I/O Resources: Up to 490 I/Os simplify board-level routing and reduce the need for additional I/O expanders in multi-interface designs.
• Industrial Temperature Range: Rated from −40 °C to 100 °C to meet environmental demands of factory, field and industrial infrastructure applications.
• Compact BGA Package: The 1156-FPBGA (35×35) package delivers a dense solution for space-constrained PCBs while supporting surface-mount assembly.
• RoHS Compliant: Facilitates compliance with lead-free manufacturing and environmental regulations.
