Embedded - FPGAs (Field Programmable Gate Array)

FPGAs or Field Programmable Gate Arrays are widely used in various applications. They generally employ gates and relay circuits to act as switches for digital logic control and storage. It allows for the flexibility of altering its logic capability without having to build a custom circuit every time a different design is required. From high-end computerized gaming to high-powered industrial logic machines, FPGAs have a range of uses and have in turn become an integral part of modern electronics.

The LFEC3E-5T144C is an FPGA from Lattice Semiconductor, one of the leading companies in developing application-specific integrated circuits (ASICs). It is a midrange FPGA with a claimed power efficiency that is around 2X better than the industry average. This FPGA was developed based on the company’s 90nm low power H-3 process. It supports a total logic block capacity of nearly 30 million and has a 512 kilobit embedded SRAM. It sports 19,200 look-up tables (LUT) and has a total I/O count of 1520. The LFEC3E-5T144C has an onboard power on reset (POR), clock chains, and I/Os. It also provides intellectual property (IP) support for functions such as high-speed transceivers and embedded peripheral blocks. This FPGA allows for considerable flexibility and offers solutions in high-speed networking, machine vision, media processing and various unique IoT applications.

Working Principle

FPGAs are built from arrays of configurable logic units, or CLUs. These can be reconfigured to form arbitrary combinatorial and sequential functions using the available resources in the FPGA. These CLUs consist of reconfigurable lookup tables, multiplexers, flip-flops, counters, register files, and other components. The user can configure these functions using a hardware description language (HDL) such as Verilog or VHDL, or using their corresponding proprietary software environments. The user can assign weights to the inputs and gate logics to the outputs of the CLUs, allowing for greater flexibility. This allows the LFEC3E-5T144C to carry out many different tasks, such as performing high-speed data processing and is a key factor that contributes to its widespread use.
