New and original LCMXO2-2000HC-4TG144C Integrated circuit

The FPGA adopts a new concept of logic cell array LCA (Logic Cell Array), which includes three parts: configurable logic module CLB, output input module IOB (Input Output Block) and internal connection (Interconnect). The basic features of FPGAs are:
1) Using FPGA to design ASIC circuits, users do not need to produce chips to get a suitable chip.　　
2) The FPGA can be used as a pilot specimen of other fully customized or semi-customized ASIC circuits.　　
3) The FPGA has a wealth of flip-flops and I/O pins inside.　　
4) The FPGA is one of the devices with the shortest design cycle, the lowest development cost and the lowest risk in the ASIC circuit.　　
5) The FPGA adopts high-speed CHMOS process, low power consumption, and can be compatible with CMOS and TTL levels.
It can be said that FPGA chips are one of the best choices for small batch systems to improve system integration and reliability.

The FPGA is programmed by a program stored in the on-chip RAM to set its operating state, so the on-chip RAM needs to be programmed when working. Users can use different programming methods according to different configuration modes.

When power-on, the FPGA chip reads the data from the EPROM into the on-chip programming RAM, and after the configuration is completed, the FPGA enters the working state. After the power is lost, the FPGA returns to white sheets, and the internal logical relationship disappears, so the FPGA can be used repeatedly. FPGA programming does not require a dedicated FPGA programmer, only a general-purpose EPROM and PROM programmer. When you need to modify the FPGA function, just change the EPROM. In this way, the same FPGA, different programming data, can produce different circuit functions. Therefore, the use of FPGAs is very flexible.
