EPM7256SQC208-10 Overview
Currently, there are 256 macro cells, which are low-power cell sites (towers, antennas, masts) that serve as radio coverage.There is a 208-BFQFP package containing it.There are 164 I/Os on the board.Terminations of devices are set to 208.QUAD is the terminal position of this electrical part.A voltage of 5Vprovides power to the device.It is recommended that the chip be packaged by Tray.The device operates at a temperature of 0°C~70°C TA in order to ensure its reliability.Ideally, the chip should be mounted by Surface Mount.The MAX® 7000S series FPGA is one of these types.The EPM7256 can be used to identify its related parts.For digital circuits, there are 5000 gates. These devices serve as building blocks.In total, there are 16 logic elements/blocks.A power supply of 3.3/55V is required to operate it.In this case, the maximum supply voltage (Vsup) is 5.25V.Vsup (supply voltage) must be greater than 4.75V.Ideally, its clock frequency should not exceed 125MHz.
