XC17S10PD8C

The XC17S10PD8C is a configuration PROM (Programmable Read-Only Memory) that is used when requiring configuration data for FPGAs. This specific device is the \'Microchip Technology XC17S1PD8C\', and is used within FPGA families such as Spartan-3, Spartan-3E, Spartan-3A, Spartan-3A DSP, Spartan-6, Aries-II and Ecoff.

In order to understand how this configuration PROM works, we must first learn about the two components of FPGA (Field Programmable Gate Array) technology: configurable logic blocks, and input/output blocks. Configurable logic blocks are highly versatile components that are programmed to have different levels of functionality. Input/output blocks are used to accept signals from external components such as transceivers and converters.

The main role of the XC17S1PD8C is to provide the configuration data to both of these components inside the FPGA. This ensures that the FPGA is properly configured for the particular application it is being used for. This data is stored inside the PROM in the form of small “words”.

When the XC17S1PD8C is first powered up, it will read out the configuration data from its memory and send it to the FPGA using a total of four pins- two data (D) pins, and two clock (CLK) pins. This process is handled by the FPGA itself and is referred to as “Serialize-Transfer”.

Once the transfer is complete, the FPGA will now be completely configured and ready to accept data. The XC17S1PD8C can also be used to upgrade the configuration data on the FPGA. To accomplish this, the PROM can be reprogrammed via the “Serial Programming Mode” (SPM). This will allow the FPGA to be programmed with the new data, making it easier to update the FPGA to meet any new requirements or applications.

The wide range of applications for the XC17S1PD8C configuration memory include digital signal processing, image processing, communication systems, industrial control, data acquisition, and embedded systems, to name a few. The configuration data stored in the PROM can be easily modified, and with the ability to be easily re-programmed, users have the flexibility to quickly switch between projects.

In summary, the XC17S1PD8C configuration PROM is an invaluable device when it comes to configuring FPGAs for a variety of applications. Its simple serial interface and programmability make it very easy to use, while its reliability ensures that FPGAs remain properly configured throughout their operating life.
