EP4CE15E22C8N Versus Xilinx Spartan-6 XC6SLX9

We usually hear questions like “ Is Altera Cyclone IV EP4CE15E22C8N or Xilinx Spartan-6 proper for my PCB design?”, or “How much is their capacity?”. Although both of them are FPGA, there are some differences between these two if we explore their specification carefully.

Know About the Specification of Altera Cyclone IV EP4CE15E22C8N

EP4CE15E22C8N in Altera Cyclone IV family gains much popularity from PCB component buyers. First of all, it contains 15408 logic elements, which is not the top one among its family but sufficient to handle the requirement of most PCB designs. Though 504 Kbits embedded memory and 56 embedded 18×18 multipliers are of middle level in the product range, it possesses the largest amount of general-purpose PLL(Phase Locking Loop), totally four units. Besides, 20 global clock networks, which is the best configuration in this product range, are equipped in EP4CE15E22C8N. When it comes to the Input or output, we highly recommended due to its good cost performance since EP4CE15E22C8N has eight user I/O bank with 343 maximum user I/O.

What’s more, it is packed in the form of QFP-144 and weights about 110 g. The work voltage for it is from 1V to 1.2V. The work temperature range for it is 0 to 70 centigrade degree. Last but not least, it is programmable for specific requirement if you have a good command of integrated circuits and computing knowledge.

Know About the Specification of Xilinx Spartan-6 XC6SLX9

XC6SLX9 also perform well as EP4CE15E22C8N with its unique construction. It has 9152 logic cells and configurable logic blocks with 1430 slices, 11440 Filp-Flops and 90Kb distributed RAM. When it comes to digital signal processing, sixteen DSP48A1 slices carried by XC6SLX9 are so versatile, serving as multiplier, multiplicative accumulator, pre-adder/subtracter, follow-by multiplicative accumulator, follow-by multiplier adder, wide bus multiplexer, amplitude comparator, and wide counter. For memory, there is 32 RAM block with 18 Kb capacity. And four I/O banks with a maximum of 200 user I/Os.
