The ALTERA MAX series includes models starting with EPM240, 570, 1270 and 2210. Today I find the corresponding model one by one to analyze the naming rules. EPM240 starts with EPM, EPM is the family series, 240 is the logical unit, G is the suffix of the product line, G is the product line representing 1.8V, VCCINT low-power devices, T is the package type, 100 is the number of pins, 100 pins, C is the temperature level, here is the commercial grade of 0-85centigrade, The position of 3 is the speed level, and 3 here represents the fastest speed. We have mentioned before that not every brand has a smaller speed value, the faster it is, which is determined by the brand. ALTERA's value is the smaller and faster. Finally, there is the optional suffix, ES is the meaning of Engineering sample. This model should be mostly with an N, which means lead-free packaging.
