Innovative Features of the Xilinx XC7K325T-2FF900I FPGA
Xilinx XC7K325T-2FF900I has some innovative features worth talking about. They range from the propagation delay to the overall performance of the IC.
Here is a detailed overview of the features that make up the Integrated Circuit (IC):
1. Wide Range of Configuration Options
The primary aim of Programmable Logic ICs, such as FPGAs is to help reprogram or reconfigure an existing set of configurations on a circuit board.
Xilinx, the manufacturer of the Xilinx XC7K325T-2FF900I provides digital designers with vast configuration options to choose from. The configuration options include but are not limited to built-in SEU detection and correction. The configuration options also include 256-bit AES encryption enhanced with HMAC/SHA-256 authentication.
2. Maximal Power Usage
Issues relating to the underperformance of a circuit board are mostly triggered by excessive power in the IC. Reducing the power and maintaining the overall performance of the board seems to be a better way to tackle that as we can see on the Xilinx XC7K325T-2FF900I FPGA.
Aside from implementing low power via the robust High-Performance, Low-Power (HPL), 28 nm, High-K Metal Gate (HKMG) process technology, Xilinx XC7K325T-2FF900I also uses lower voltage. The core voltage technology power the low-power and high-performance are the 0.9 volts core voltage and the 1.0 volts core voltage technologies.
3. Propagation Delay
Wikipedia defines Signal Propagation Delay as the “time duration taken for a signal to reach its destination.” Considering that signals need to be transmitted and received on time in an FPGA, it makes sense to have a feasible propagation delay time.
The Xilinx XC7K325T-2FF900I FPGA has a propagation delay of 0.1 ns (maximum), which is feasible to transmit the signal and possibly, change it.
Wrapping Up
Xilinx XC7K325T-2FF900I is an awesome Field Programmable Gate Array (FPGA) designed to help you get the most out of your investment in digital circuits.
A bulk of the work is entrusted to a reliable digital designer like RayPCB. We also provide professional advice to help you better understand how to make the most out of the Integrated Circuit (IC).
