XC4028XLA

Features:

XC4000XLA/XV Family Features
Note: XC4000XLA devices are improved versions of XC4000XL devices. The XC4000XV devices have the same features as XLA devices, incorporate additional interconnect resources and extend gate capacity to 500,000 system gates. The XC4000XV devices require a separate 2.5V power supply for internal logic but maintain 5V I/O compatibility via a separate 3.3V I/O power supply. For additional information about the XC4000XLA/XV device architecture, refer to the XC4000E/X FPGA Series general and functional descriptions.
