Xilinx FPGA Configration control LSI
 TE7725PF
 

[Release Schedule]
Mass Production Now


The inrevium TE7725PF is a second generation FPGA configuration control LSI. The TE7725PF is enabling to configure the Xilinx FPGA with a NOR flash memory on the board instead of using conventional PROMs. Up to 256Mbit flash memory is supported and both 2.5V/3.3V IO voltages are helpful for various kinds of Xilinx FPGA family.
With sharing a flash memory chip on the board both for CPU boot memory and FPGA configuration data, the TE7725PF helps to significantly reduce a board size and a total cost.
In addition, the TE7725PF supports the Master Select MAP mode, the configuration in a parallel interface for a high-speed configuration. This solution would be useful to reduce a configuration time for high-density FPGAs.
