[Package Size]
100Pins QFP 16×16mm
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.

Alphabet charactor represents following notice.

R= BGA package ( The product number without "R" is provided by QFP package.)
PF= Pd Free products
Note) The alphabet circled ( ) means package option product is available to the customers.
ie. TExxxxPF(RPF) has tow package options (BGA and QFP) and both are Pb Free.
