Xilinx XC2S50-5TQG144C is the definition of a power-packed FPGA with optimum performance. The IC is powered by the cost-effective 0.18um technology process. As a Spartan-II FPGA, it packs power, maximum performance and low-cost in the same circuit.
Technical Specifications of XC2S50-5TQG144C
The technical specifications of the XC2S50-5TQG144C FPGA are detailed below.
I/O
Input and Output (I/O) refers to the physical structures or interfaces through which the FPGA can be connected to other devices in the system.
I/Os also bolster signal transmission, especially via the translation of analog or digital signals for enhanced processing of the signals in an FPGA target.
XC2S50-5TQG144C has a total of 92 I/Os.
Logic Array Blocks (LABs)
Logic Array Blocks (LABs), also known as Configurable Logic Blocks (CLBs) are the fundamental building blocks of an FPGA.
According to Wikipedia, LABs or CLBs can be configured to provide reconfigurable logic gates.
XC2S50-5TQG144C has a total of 384 LABs/CLBs.
Random Access Memory (RAM)
There are two types of RAMs on the XC2S50-5TQG144C FPGA. These are the Distributed RAM and Embedded Block RAM (EBR).
The Distributed RAM is built alongside the Look-Up Tables (LUTs). By design, it is meant to distribute or transmit data across the FPGA. The idea is to enable the asynchronous reading of data, even though it may be possible to use a clock to write the distributed RAM to synchronous.
On the other hand, Embedded Block RAM (EBR) is a type of FPGA memory that stores a large amount of data. It is also faster, when compared to distributed RAM. This is the reason why most designers prefer having it on the board, as it takes less space and scales the design process.
Temperature Rating
XC2S50-5TQG144C maintains a flexible temperature rating. Its operating supply voltage is 2.5 volts, while the maximum operating temperature is 85-degree Celsius.
Buying Guide for XC2S50-5TQG144C
Interested in buying the XC2S50-5TQG144C? Here is a guide that should help you make an accurate buying decision.
1. Resource Allocation
This has to do with the distribution of resources or the architecture that make up the FPGA. As a Spartan-II series FPGA, XC2S50-5TQG144C has some resources peculiar to it. This includes the 1,728 Logic Cells and 384 Logic Array Block (LABs).
Find out the resource allocation ratio of the IC to be sure it has some of the resources you need for the programming.
2. Operating Temperature
What is the manufacturer’s rating for the temperature? Typically, the temperature should match the application.
For example, FPGAs required for high-powered applications need to have higher operating temperature rating.
3. I/O Pins
Input and Output (I/O) pins are the number of pins that enable the input and removal of data from the system.
The XC2S50-5TQG144C has a total of 144 pins. The rule of thumb is to make sure that the FPGA you want to buy has enough I/O pins to cater for the design you need.
Conclusion
FPGAs aren’t cheap, but some are affordable. XC2S50-5TQG144C is one of the affordable FPGAs you can find in the market. Contact RayPCB to get an idea of what it would cost to design one for you.
