Applications and use cases

EP4CE115F23C9L FPGAs are suitable for a broad range of
 applications, such as industrial automation, transportation, smart energy, medical, telecommunication, and aerospace. They are beneficial in applications that require powerful yet low energy devices, allowing them to be integrated into smaller systems. The low power consumption, multiple I/O options, high logic density, and reasonable cost of the FPGA makes it a good choice for embedded applications.

For example, EP4CE115F23C9L can be used for industrial control, where it can be used 
to rapidly develop controllers, custom logic blocks, IPs, and data acquisition systems. The on-chip features such as Integrated Dynamic Power Management (DPM), high-speed GPIOs, and multi-protocol communication interface make it beneficial in factory automation applications. The EP4CE115F23C9L FPGA can also be used in advanced video systems for example for providing video analytics or for low-level video processing in embedded systems.

Additionally, EP4CE115F23C9L can be used in streamlined energy management and remote energy monitoring systems, where it can be used to construct logic and memory blocks that facilitate communication over Azure Internet of Things (IoT) Hub and other communication protocols like MQTT. This can allow a system to communicate with the cloud remotely and control various devices. The FPGA can also be used in medical equipment, where it can be used to generate data-driven analytics or to generate custom logic functions.

Working Principle

The EP4CE115F23C9L FPGA is comprised of multiple configurable logic blocks, embedded memory blocks, and I/O blocks. Its configurable logic blocks (CLB) are the fundamental building blocks of the FPGA and are used for implementing combinational and sequential logic functions. The CLBs are rendered by way of programmable logic elements (PLEs) and programmable interconnect elements (PIEs). The PLEs are a combination of lookup tables and flip-flops, while the PIEs contain the interconnecting signals between the PLEs. This helps to reduce the number of interconnects necessary for the FPGA.

The CLBs are connected to the embedded memory blocks and I/O blocks to provide access to information from the outside world and system configuration. For example, the I/O blocks can access a variety of input/output protocols, including USB, Ethernet, SPI, and UART. The embedded memory blocks are based on configuration devices that allow the user to customize them for specific operations. For example, RAM, ROM, and FIFO memory blocks can be used for storing data, instructions, and states, respectively.

The EP4CE115F23C9L FPGA can be programmed using a variety of languages, including Verilog, VHDL, and AHDL. The programming process starts with developing a hardware description language (HDL) source code, which describes the logic elements of the circuit. This code is then translated by a synthesis tool into a net-list which is then mapped to the FPGA architecture. The last step is to load the resulting bit-stream into the FPGA.

The EP4CE115F23C9L is also equipped with Intel STRATIX device, which provides integrated, high-speed serializers/deserializers (SERDES). This allows the FPGA to support multiple layers of I/O protocols, thus increasing the design flexibility. The FPGAs also include high-speed, compatible Altera I/O pins, which provide additional features such as low power consumption and fast I/O timing.

Conclusion

In summary, the EP4CE115F23C9L FPGA is a versatile, low-power, and cost-effective solution for embedded and advanced PC applications. Its configurable logic blocks, embedded memory blocks, and I/O blocks make it a powerful choice for industrial automation, transportation, smart energy, medical, telecommunication, and aerospace applications. With its support for various programming languages, high-speed GPIOs, and configurable I/O protocols, the EP4CE115F23C9L can be quickly and easily deployed in a variety of projects.
