Lattice LAE3-17EA-6FTN256ETR: A Comprehensive Technical Overview of the FPGA Device

The Lattice LAE3-17EA-6FTN256ETR 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 integrates robust programmability with features essential for high-reliability environments where performance, security, and longevity are critical.

Architecturally, this FPGA is built on a low-power, high-performance platform optimized for processing in size, weight, and power (SWaP)-constrained systems. It features 17K Look-Up Tables (LUTs) alongside embedded memory blocks, DSP slices for digital signal processing, and hardened IP cores that facilitate rapid implementation of complex functions. The inclusion of 6-input fracturable LUTs enhances logic efficiency, allowing for more complex combinatorial logic to be implemented in fewer resources.

A key aspect of the LAE3-17EA-6FTN256ETR is its radiation-hardened design, which ensures reliable operation in harsh environmental conditions, including resistance to single-event upsets (SEUs) and latch-up. This makes it particularly suitable for space missions, avionics control systems, and other critical aerospace operations. The device also supports advanced security features, such as bitstream encryption and authentication, to protect intellectual property and prevent unauthorized access or tampering.

The package, a 256-ball Fine-Pitch Thin Ball Grid Array (FTN256B), offers a compact footprint essential for modern avionics systems while providing sufficient I/O count and thermal performance. It supports a range of I/O standards, including LVCMOS and LVDS, enabling flexible interface with other system components.

In terms of development, the device is supported by Lattice's proprietary design software and IP libraries, which streamline the implementation of communication protocols, motor control algorithms, and sensor fusion tasks common in its target applications.
