EP4CE40F23I8L

Field Programmable Gate Array (FPGA) is an integrated circuit designed to be configured by a customer or a designer after manufacturing – hence the term “field-programmable”. FPGA, like other integrated circuits can be found in all kinds of electronic appliances from computers to remote control units. The particular type of FPGA studied in this article is the EP4CE40F23I8L, which belongs to the Altera Cyclone IV GX series.

Application Field

It’s widely used for making digital designs, such as:

• General embedded control applications
• Industrial network communications systems
• Medical equipment
• Open source projects
• Automotive and military applications

Features

The EP4CE40F23I8L provides several features which make it an attractive device to use:

• It supports more than 21k logic elements, 173k Bits of internal memory, and 504 user I/O pins.
• The device has a total of 62 4-input lookup tables (LUTs) with 4-input flip-flops.
• It provides a maximum clock frequency of 450MHz (5ns) and a maximum data transfer rate in/out of 2Gbps when using the dedicated transceiver channels.
• The device offers an entire Ethernet MAC/PCS transceiver that enables Ethernet 10/100/1000 applications.
• It IS also composed of several up to 8 megabyte single-port, dual-port, and UltraRAM memories.

Working Principle

FPGAs work by taking multiple CMOS transistors and arranging them in “logic cells.” Each logic cell has a programmable structure with predefined functions and logic gates. These logic cells can be programmed by engineers to make custom logic designs. This makes FPGAs exceptionally versatile and cost-effective, since the same chip can be used to make different designs.

FPGAs can be easily programmed with a variety of software tools. The engineer writes his/her own Verilog or VHDL code to design the custom FPGA logic. This code is then compiled into a bitstream file and uploaded to the target FPGA. Upon receiving the bitstream file, the FPGA configures itself according to the new design.

Conclusion

Using the EP4CE40F23I8L, engineers have access to a versatile and powerful FPGA platform. Its impressive specs and wide range of application fields make it the perfect choice for many projects. Additionally, its easy programmability make for rapid prototyping, making it an excellent choice for quick and cost-effective design solutions.
