AMD XC2V40-6CSG144C

Overview

XC2V40-6CSG144C from Xilinx is a 40K-system-gate Virtex-II platform FPGA in a 144-pin chip-scale BGA (CSG144) package, operating at commercial temperature range (0°C to +85°C) with -6 speed grade. It integrates 256 Configurable Logic Blocks (CLBs), 8 18×18 multipliers, 4 Block SelectRAM™ modules (72 Kbits total), and 4 Digital Clock Managers (DCMs). It targets high-speed I/O interface design in telecom and DSP applications requiring LVDS, PCI, or DDR signaling.

For engineers reviewing the XC2V40-6CSG144C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (88 user I/Os), DCI-enabled on-die termination for HSTL/SSTL/LVCMOS standards, dual-register DDR I/O support, 1.5 V core voltage, and compatibility with Xilinx Foundation/Alliance design tools.

Technical Context

The XC2V40-6CSG144C implements a hierarchical SRAM-based architecture with four major configurable resources: IOBs supporting 19 single-ended and 6 differential I/O standards; CLBs containing 256 slices (each with dual 4-LUTs and dual flip-flops); 18 Kb Block SelectRAM modules configurable as 16K×1 to 512×36 dual-port RAM; and DCMs providing digital clock de-skew, frequency synthesis (M/D ratio), and ±1/256-period phase shifting.

Routing uses fourth-generation Active Interconnect Technology with 24 long lines per row/column, shared timing models across all logic elements, and predictable delay independent of fanout. Configuration occurs via Slave/Master SelectMAP or JTAG (IEEE 1532), with optional Triple-DES bitstream encryption and full readback capability for debug.

FAQ

What is the maximum number of user I/Os supported by XC2V40-6CSG144C?

XC2V40-6CSG144C supports 88 user I/Os in its CSG144 package. This count excludes 15 dedicated control pins (CCLK, DONE, M0–M2, PROG_B, PWRDWN_B, TCK, TDI, TDO, TMS, HSWAP_EN, DXN, DXP, RSVD) and VBATT. The I/O count is fixed for this device/package combination per Xilinx DS031 Table 6.

Does XC2V40-6CSG144C support DDR I/O interfaces?

Yes, XC2V40-6CSG144C supports true DDR I/O through dedicated input and output registers within each IOB. Each path can use two edge-triggered registers clocked by 180° phase-shifted signals generated by its DCMs, enabling single-ended or differential DDR operation compliant with DDR SDRAM and other source-synchronous protocols.

What clock management resources does XC2V40-6CSG144C include?

XC2V40-6CSG144C integrates 4 Digital Clock Manager (DCM) modules. Each DCM provides digital clock de-skew, frequency synthesis (M/D ratio), coarse and fine phase shifting (down to ±1/256 of period), and duty cycle correction-enabling precise clock domain management for mixed-speed interfaces like PCI, LVDS, and internal logic.

Is XC2V40-6CSG144C compatible with Xilinx ISE design tools?

Yes, XC2V40-6CSG144C is fully supported by Xilinx ISE Foundation and Alliance Series development tools. These tools provide VHDL/Verilog synthesis, place-and-route, timing analysis, and bitstream generation specifically validated for the Virtex-II architecture and XC2V40-6CSG144C speed grade and package.

What is the core voltage requirement for XC2V40-6CSG144C?

XC2V40-6CSG144C requires a 1.5 V ±3% core supply (VCCINT) for its internal logic array. It also needs a 3.3 V auxiliary supply (VCCAUX) for configuration circuitry and I/O bank supplies (VCCO) set per I/O standard-ranging from 1.5 V to 3.3 V depending on selected IOSTANDARD attribute.
