The UA1E series of ULCs is well suited for conversion of large sized CPLDs and FPGAs. We can support within one ULC from 18 Kbits to 390 Kbits DPRAM and from 46 Kgates to 780 Kgates. Typically, ULC die size is 50% smaller than the equivalent FPGA die size. DPRAM blocks are compatible with Xilinx or Altera FPGA blocks. Devices are implemented in highperformance CMOS technology with 0.35m (drawn) channel lengths, and are capable of supporting flipflop toggle rates of 200 MHz at 3.3V and 180 MHz at 2.5V, and input to output delays as fast as 150ps at 3.3V. The architecture of the UA1E series allows for efficient conversion of many PLD architecture and FPGA device types with higher IO count. A compact RAM cell, along with the large number of available gates allows the implementation of RAM in FPGA architectures that support this feature, as well as JTAG boundaryscan and scanpath testing.
