Embedded FPGAs, such as the LFECP10E-3F256C, provide high levels of flexibility, programmability, and scalability to engineers or technicians who need mixed-signal circuit components for field or laboratory applications.

The LFECP10E-3F256C is an embedded FPGA designed to provide 4-bit data storage memory and logic control functions that can help realize the design of a variety of embedded systems. It is based on a 32-bit RISC processor core and a cost-effective non-volatile 256-cell programmable FPGA fabric. The LFECP10E-3F256C is packaged in a small 40-pin TQFN package that is suitable for harsh field environment applications.

The LFECP10E-3F256C has various application fields and can be used in a variety of embedded system designs, such as industrial automation equipment, consumer electronics, automotive electronics, communications, home security and alarm systems, safety and surveillance systems, medical equipment, and aerospace avionics systems.

The programmable fabric of the LFECP10E-3F256C is capable of supporting a wide range of programmable logic functions. This includes programmable N-LUTs (Look-Up Tables) and a variety of opcode functions such as A/D, D/A, PWM (Pulse Width Modulation) and serial communication interfaces. The LUTs make it possible to design digital logic functions such as multiplexers, logic gates, and counters with a single chip.

The LFECP10E-3F256C also includes on-chip RAM that provides 4K of data storage for program execution and data sharing between user and the CPU. The 4K SRAM also includes error-detection and correction CRC (Circuit Redundancy Check) for safeguarding data integrity. There is also a built-in 17-bit counter that provides a high-resolution time-keeping function. This allows the LFECP10E-3F256C to be used in applications such as motor speed control, alarm clock functions, and other timing-critical systems.

Besides, the LFECP10E-3F256C also contains 6 programmable E1 (Embedded 1) timers. These are used to initiate actions or monitor events while the CPU is off or executing a different part of the program. They can be used to shcedule events, detect and record timing information, and trigger interrupts. This feature adds a layer of flexibility to the LFECP10E-3F256C, making it suitable for complex embedded systems applications.

In terms of its working principle, the LFECP10E-3F256C employs a 32-bit instruction-set processor core that allows the FPGA fabric to be connected to a central processor unit via the EBI (External Bus Interface). The 32-bit CPU receives instructions and data through the EBI from an external memory from which it can execute programs or signal processing operations. The CPU is also connected to the FPGA fabric via the EBI, which are configured by the user to realize the user’s desired functionality. The FPGA fabric is then programmed with the user’s code and the outputs of FPGA are connected to the required peripheral areas.

In summary, the LFECP10E-3F256C is a highly-flexible, cost-effective and low-power embedded FPGA that can be a great addition to any embedded system design to aid in controlling, monitoring and sensing application. Its field programmable fabric supports a wide range of logic functions, while its on-chip RAM provides data storage, error correction and high-resolution time-keeping. Furthermore, it provides a total of six E1 timers for extra flexibility and control.
