Chip Altera Cyclone naming rules，Chinese chip Will replace it？

-Original content, please do not reprint.
The reason for return disputes or business losses caused by purchasing components with the wrong type, is that the purchasing or sales staff do not have enough know about chip naming rule, and the chip types they receive are not complete enough. The relevant staff do not kown about this. FPGA high-performance components are often more expensive. If you get it wrong, the loss will be even greater. Today we use a table to analyze the naming rules of most chips of the ALTERA Cyclone series. and We'll talk about Why the Altera Cyclone series has a high chance of being replaced by Chinese chips?

    Most models of the ALTERA CYLCONE series are composed of the following named modules. Family series series characteristics. It should be noted here that not all products are composed of series characteristics, device type, member code, and support for quick turn-on function. Note that this function is not available for everyone. Each model has it, package pin number, temperature, speed and packaging information.




EP4CE40F29C8N

• Let’s take a look at this model first. EP4C is the fourth generation product of Cyclone and belongs to the family series. E represents the characteristics of this model. E means enhanced logic and memory. (Enhanced logic/memory means enhanced logic/memory. ), the 40-member code corresponds to the number of logical units (usually named with a number above the thousandth digit of the number of logical units, for example, if there are 10,320 logical units, 10 is used as the code name), F represents the package type FBGA, 29 The representative pin number is 780 pins, C represents the commercial temperature 0 to 85℃, 8 represents the speed grade, and N represents lead-free.





EP3C25F324C7N


• Let’s take a look at another model. EP3C means Cyclone’s third-generation product corresponds to the family series. 25 is the member code corresponding to the number of logical units. F is the package type. This is the FBGA package. 324 is the number of pins. C represents the operating temperature. 7 represents speed grade, N represents lead-free.









EP2C70AF324C7ES

• Let’s take a look at the EP2C70AF324C7ES model. First of all, EP2C is the second-generation product family series of Cyclone. This model has no series features. Here, 70 is the device type, A is fast turn-on (POR time), F is package type FBGA, 324 is the number of pins, C is the operating temperature, which represents the commercial temperature 0 to 85℃, 7 is the speed grade, and ES represents the engineering sample.






What is the status of domestic substitution of Altera Cyclone series?

• Why is it said that the Altera Cyclone series has a higher chance of replacing Chinese chips? There are two main reasons: 1: Opponents have given Chinese chips opportunities. After Altera was acquired by Intel, it prefers to make high-profit products.

• 2：Gradually looking down on pure FPGA series with lower technical thresholds, coupled with the opportunity of shortages in the past two years, users urgently need other cheaper alternatives, and Chinese domestic chip products that are compatible with the Altera Cyclone series of FPGAs have begun to appear.

• In fact, FPGA started in the 1990s and was one of the first categories of processor chips to be replaced by Chinese chips. It was not used in the past. China's FPGA is now gradually entering the industrial, communications and automotive markets.
