Embedded FPGAs (Field Programmable Gate Arrays) offer a versatile solution when a device or system circuitry needs to be adaptable or rapidly modified. The LFE2-20E-6F484C is an example of a low power Embedded FPGA that can be used to optimize multiple design applications.

The LFE2-20E-6F484C is capable of functioning as a logic gate and six input look-up table for logic functions where circuit complexity requires a greater level of configurability. Added to this, its small size further enhances its practicality when designing complex digital systems with minimal voltage requirement, making it useful for a range of embedded applications.

Its internal structure can be broken down into four modules, each providing the core functionality for multiple applications. Firstly, the logic block allows for quick execution of basic logic functions and includes a 4-K (1248-cells) array of programmable logic blocks as well as sixteen 16-bit register/combinators. Secondly, the input/output block provides ten BiCMOS hardwired PIOs and four dedicated BiCMOS external transceivers. Thirdly, the RAM block features an eight-Kb dual port RAM and a four-Kb single port RAM. And finally, the configuration block consists of a serial bus, a single 2-Kb SPI Flash memory and a configurable 13-bit 15-MHz microcontroller (MCU).

The main purpose of the LFE2-20E-6F484C is to enable a single device to replace multiple ASICs, thus allowing for efficient scalability and redundancy in complex systems. This versatility is due to its reconfigurable nature, whereby multiple logic and memory functions can be built into a single integrated circuit. As a result, it can be used for a multitude of applications including display and communication, digital signal processing (DSP), image/video processing and automotive as well as other embedded systems.

The LFE2-20E-6F484C works by utilizing a system of programmable building blocks that are programmed to perform specific tasks. These building blocks are then connected and configured according to the user’s desired functionality. The user can program the LFE2-20E-6F484C by connecting the logic blocks together and setting the internal connections and logic levels. The FPGA can then be programmed and tested for functionality, allowing for the embedded application to be built and tested quickly.

In summary, the LFE2-20E-6F484C is an efficient, low-power embedded FPGA. Its small size and reconfigurable nature make it a highly practical solution for a range of applications, from automotive to digital signal processing. The FPGA is able to effectively replace multiple ASICs, significantly reducing the cost and time associated with manufacturing complex digital systems.
