AMD XC2V40-5CSG144C

Overview

XC2V40-5CSG144C from Xilinx is a 40K-system-gate Virtex-II platform FPGA in a 144-pin chip-scale BGA (CSG144) package, operating at -5 speed grade with commercial temperature range (0°C to +85°C). It integrates 256 Configurable Logic Blocks (CLBs), 8 18×18 multipliers, 4 Digital Clock Managers (DCMs), and supports up to 88 user I/Os with SelectIO-Ultra technology including LVDS, SSTL, HSTL, and PCI-compliant interfaces. It is used in high-speed communication interface bridging and embedded DSP acceleration.

For engineers reviewing the XC2V40-5CSG144C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (88), DCM count (4), CLB count (256), core voltage (1.5 V), and support for DDR I/O registers and on-chip digitally controlled impedance (DCI) for single-ended standards.

Technical Context

The XC2V40-5CSG144C implements a SRAM-based, reprogrammable architecture built on a 0.15 µm/0.12 µm 8-layer metal CMOS process. Its logic fabric comprises 256 CLBs-each containing four slices with dual 4-input LUTs, flip-flops/latches, carry chains, and distributed RAM-and 4 dedicated 18×18 multipliers tightly coupled to 4 × 18-Kb Block SelectRAM modules.

It features four Digital Clock Managers (DCMs) supporting precise de-skew, frequency synthesis (M/D ratio), and coarse/fine phase shifting (down to 1/256 clock period), plus 16 global clock multiplexer buffers. I/O subsystem includes Digitally Controlled Impedance (DCI) for on-die termination and DDR-capable IOBs compliant with LVDS, SSTL-2/3, HSTL, and PCI-X/PCI standards.

Key Specifications

Pinout & Package

XC2V40-5CSG144C is housed in a 12 mm × 12 mm, 0.80 mm pitch chip-scale BGA (CSG144) package with 144 solder balls. The package supports wire-bond interconnect and Pb-free assembly per JEDEC J-STD-020. Pin definitions follow Xilinx's standard Virtex-II CSG144 pinout layout, with dedicated configuration, clock, and I/O banks arranged around the perimeter.

FAQ

What is the maximum operating frequency of the XC2V40-5CSG144C core logic?

The XC2V40-5CSG144C supports internal clock speeds up to 420 MHz (advance data), with actual achievable frequency dependent on design complexity and routing. Its -5 speed grade guarantees timing closure for critical paths at 350 MHz under typical commercial conditions, as validated in Xilinx DS031 Module 3 switching characteristics.

Does the XC2V40-5CSG144C support JTAG boundary-scan testing?

Yes, the XC2V40-5CSG144C fully complies with IEEE 1149.1 (JTAG) and supports BYPASS, SAMPLE, EXTEST, INTEST, and HIGHZ instructions. Its Test Access Port (TAP) enables configuration, debug, and production test via TCK/TMS/TDI/TDO pins defined in the CSG144 pinout.

Can the XC2V40-5CSG144C interface directly with DDR SDRAM?

Yes, the XC2V40-5CSG144C supports DDR SDRAM interfaces through its SelectIO-Ultra I/Os with dedicated DDR input/output registers and programmable drive strength. It meets timing requirements for 133 MHz DDR (266 Mb/s) when used with appropriate PCB layout and VCCO = 2.5 V.

Is on-chip termination (DCI) available for all I/O standards on the XC2V40-5CSG144C?

DCI is supported for LVCMOS, SSTL, HSTL, GTL/GTLP, and LVDS standards per Table 3 in DS031 Module 2, but only in specific I/O banks configured for compatible VCCO and reference voltages. Not all 88 I/Os support DCI simultaneously - bank-specific constraints apply.

What configuration modes does the XC2V40-5CSG144C support?

The XC2V40-5CSG144C supports five configuration modes: slave-serial, master-serial, slave SelectMAP, master SelectMAP, and IEEE 1532 boundary-scan. Configuration is initiated via PROG_B and controlled by M0–M2 pins, with CCLK driving the bitstream load sequence.
