Field Programmable Gate Array (FPGA) is a type of integrated circuit (IC) used to design digital circuits and systems. In FPGA devices, the logic functions of the chip are implemented by the user, allowing them to be easily modified and optimized for specific applications. The EP1M120F484C7A is a mid-range FPGA manufactured by Altera Corporation, a leading provider of customizable logic devices. In this article, we will discuss the application fields and working principles of EP1M120F484C7A.

Application Field

EP1M120F484C7A is intended for low and mid-density applications that require high performance and many configurable resources. It is suitable for a wide range of applications in industrial, automotive, aerospace and communication sectors. Some of its key features include full-speed flight process, logic DSP blocks, multi-protocol transceivers, high speed I/O and configurable logic blocks (CLBs).

The EP1M120F484C7A features a comprehensive logic process system (LPS) and embedded hardened memory controller (EMC). The LPS offers high efficiency and can process up to 400MHz when clocked at 125MHz. The EMC consists of dual 64KB RAMs, a 160MBps controller bus and up to 16MB of reprogrammable flash. This combination allows the device to implement complex algorithms and interfaces in a cost-effective manner.

In addition, the device also includes dedicated security features such as physical-layer encryption, secure boot and secure key storage. This ensures that the device is secure from cyber-attacks and is immune to tampering or reverse engineering. The EP1M120F484C7A is also designed for reliability and long life-cycles.

Working Principle

The working principle of the EP1M120F484C7A is based on the concept of programmable logic blocks (PLBs). PLBs are self-contained blocks of logic that can be used to construct complex digital circuit designs. Each PLB contains a set of inputs, outputs and connectors that can be used to build various integrated circuit functions. Once the PLBs are connected, the internal logic of each PLB is configured and the appropriate signals are routed to the right places.

After the PLBs are configured and connected, the user uses a logic synthesis and compilation process to generate a netlist of the circuit. The netlist is then used to map the circuit onto the physical EP1M120F484C7A FPGA device. This process is done by a dedicated translation software tool. Once the mapping is done, the user can program the device with the appropriate configuration code.

The EP1M120F484C7A uses a number of configurable logic blocks (CLBs), 1Kbit RAMs, multi-channel DMA engines and two 64kbit RAMs. The RAMs are used to store data and instructions, while the DMA engines are used to transfer data between the RAMs and the PLBs. The CLBs are used to construct complex logic functions from the inputs and outputs of the PLBs.

Once the configuration code is programmed into the device, it is ready for operation. The FPGA can then be used to implement any type of digital logic circuit design. This includes everything from simple logic gates to more complex microprocessors and system-level components. With a wide range of configurable resources, the EP1M120F484C7A can handle a variety of applications with ease.
