AMD XC2V40-4CSG144C

Overview

XC2V40-4CSG144C from Xilinx is a 40K-system-gate Virtex-II platform FPGA in a 144-ball chip-scale BGA (CSG144) package, operating at commercial temperature range (0°C to +85°C) with -4 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), targeting high-speed I/O interfacing and embedded logic acceleration in telecom and DSP systems.

For engineers reviewing the XC2V40-4CSG144C datasheet, pinout, applications, or equivalent options, key selection criteria include its 88-user-I/O count, 1.5 V core supply, DCI-enabled LVCMOS/LVDS I/O support, and compatibility with Xilinx Foundation/Alliance design tools for SRAM-based in-system configuration.

Technical Context

The XC2V40-4CSG144C implements a hierarchical architecture with IOBs supporting DDR registers, programmable sink current (2–24 mA), and Digitally Controlled Impedance (DCI) for on-die termination across 19 single-ended and 6 differential I/O standards. Its CLB array comprises 256 blocks (8×8 grid), each containing four slices with dual 4-input LUTs, dual flip-flops/latches, and fast carry chains.

Routing uses fourth-generation Active Interconnect Technology with 24 long lines per row/column, predictable delay independent of fanout, and shared timing models across IOBs, CLBs, SelectRAM, multipliers, and DCMs. Each of the 4 DCMs provides de-skew, frequency synthesis (M/D ratio), and fine-grained phase shifting (1/256 clock period resolution).

Key Specifications

Pinout & Package

XC2V40-4CSG144C is housed in a 144-ball Chip-Scale BGA (CSG144) package with 0.80 mm pitch, 12 mm × 12 mm body size, and Pb-free construction. The package supports wire-bond interconnect and delivers 88 user I/Os plus 15 dedicated configuration/control pins (CCLK, DONE, M0–M2, PROG_B, PWRDWN_B, TCK, TDI, TDO, TMS, HSWAP_EN, DXN, DXP, RSVD) and VBATT.

FAQ

What is the maximum operating frequency of the XC2V40-4CSG144C?

The XC2V40-4CSG144C has a -4 speed grade, meaning its internal logic can operate up to 400 MHz under typical conditions, with DCM outputs supporting up to 420 MHz (advance data). Actual achievable frequency depends on design complexity, routing, and I/O standard selection-verified via Xilinx ISE timing analysis using the specific -4 speed file.

Does the XC2V40-4CSG144C support JTAG boundary-scan testing?

Yes, the XC2V40-4CSG144C fully complies with IEEE 1149.1 (JTAG) and supports BYPASS, SAMPLE, PRELOAD, EXTEST, INTEST, HIGHZ, IDCODE, and USERCODE instructions. Its Test Access Port (TAP) enables configuration, debug, and production test without requiring additional test circuitry.

Can the XC2V40-4CSG144C interface directly with DDR SDRAM?

Yes, the XC2V40-4CSG144C supports DDR SDRAM interfaces through its SelectIO-Ultra I/O banks, which provide dedicated DDR input and output registers, programmable drive strength, and SSTL_2_I/II compatibility. External termination and careful PCB layout are required, but no external logic is needed for basic read/write operations.

Is bitstream encryption available on the XC2V40-4CSG144C?

Yes, the XC2V40-4CSG144C includes on-chip Triple-DES decryption hardware. When enabled, it secures the configuration bitstream using one or two 168-bit keys stored in non-volatile memory, preventing unauthorized readback or cloning of the programmed logic design.

What development tools are compatible with the XC2V40-4CSG144C?

The XC2V40-4CSG144C is supported by Xilinx Foundation Series and Alliance Series design environments, including ISE 6.x–14.7. These tools provide VHDL/Verilog synthesis, place-and-route, timing analysis, and configuration bitstream generation specifically validated for the Virtex-II architecture and -4 speed grade.
