XC2C256-7VQG100C

XC2C256-7VQG100C Overview

The XC2C256-7VQG100C, which has 256 macrocells, is designed for both high-performance and low-power applications. High-tech communication equipment can use less energy as a result, and battery-operated gadgets have exceptional speed. The dynamic operation and low power stand-by improve the overall system reliability.

This XC2C256-7VQG100C is made up of sixteen Function Blocks that are connected by the Advanced Interconnect Matrix (AIM), a low power interconnect architecture.The AIM sends 40 true and complement inputs to each Function Block. The Function Blocks are composed of a 40 by 56 P-term PLA and 16 macrocells with a number of configurable bits that enable combinational or registered modes of operation.

The 0.18 micron process technology used in the fabrication of XC2C256-7VQG100C is a byproduct of cutting-edge FPGA product development. RealDigital, a design methodology that uses CMOS technology in both the fabrication and design methods, is used by CoolRunner-II CPLDs. Instead of using the conventional sense amplifier approach, RealDigital design technology implements sums of products using a cascade of CMOS gates. This innovation enables the operation of Xilinx CoolRunner-II CPLDs at both high performance and low power.

I/O implementations for LVCMOS, LVTTL, SSTL, and HSTL are available on the XC2C256-7VQG100C’s 256 macrocell. A general-purpose EIA/JEDEC standard for 3.3V applications that use an LVTTL input buffer and Push-Pull output buffer is called the LVTTL I/O standard. Applications requiring 3.3V, 2.5V, and 1.8V use the LVCMOS standard. A VREF pin is used by the HSTL and SSTL I/O standards in order to comply with JEDEC. Schmitt-trigger inputs enable 1.5V I/O compatibility for CoolRunner-II CPLDs as well.
