Lattice LAE3-17EA-6FTN256E: A Comprehensive Technical Overview of the FPGA Device
The Lattice LAE3-17EA-6FTN256E is a specific member of Lattice Semiconductor's certified-aviation-focused FPGA family, designed to meet the stringent requirements of aerospace and defense applications. This device exemplifies the integration of high reliability, low power, and robust performance in a demanding environment. Built on a mature, low-power process technology, this FPGA offers a deterministic and predictable response, which is critical for safety-critical systems such as flight controls, avionics displays, and mission computing.
A core architectural highlight of the LAE3-17EA is its inherent support for triple-modular redundancy (TMR). Designers can configure the FPGA's logic, memory, and DSP blocks to operate in lockstep, allowing the device to automatically detect and correct single-event upsets (SEUs) caused by radiation in high-altitude applications. This radiation-hardened approach significantly enhances system reliability without requiring extensive external mitigation components. The device features approximately 17K Look-Up Tables (LUTs), providing a substantial amount of programmable logic for implementing complex control and interfacing functions. The inclusion of embedded block RAM (EBR) and distributed RAM offers flexible memory resources for data buffering and storage.
The `-6FTN256C` suffix provides key package and performance details. The device is housed in a fine-pitch, 256-ball Fine-Pitch Ball Grid Array (FTN256) package. This compact package is suitable for space-constrained board designs common in airborne systems. The `-6` speed grade indicates a robust performance level, ensuring timing closure for designs operating in challenging environmental conditions. The device's I/O banks are highly flexible, supporting a wide range of voltage standards (e.g., LVCMOS, LVTTL), which is essential for interfacing with various sensors, memory, and processors in an avionics suite.
Power efficiency is a cornerstone of its design. The LAE3-17EA leverages Lattice's low-power expertise to achieve a remarkably low static and dynamic power consumption. This trait is vital for reducing the thermal footprint and overall power budget of the system, a key consideration in airborne platforms where heat dissipation and weight are critical factors. Furthermore, the device is supported by Lattice's proven development tools, including the Lattice Radiant software suite. This environment provides comprehensive design entry, synthesis, place-and-route, and verification capabilities, including specific features for analyzing and implementing TMR configurations.
From a security perspective, the FPGA offers features to protect intellectual property. It supports bitstream encryption to prevent unauthorized cloning or reverse engineering of the design, ensuring the integrity of the proprietary algorithms and system functionality.
