AMD XC2V40-4CSG144I

Overview

XC2V40-4CSG144I from Xilinx is a 40K-system-gate Virtex-II platform FPGA in a 144-ball chip-scale BGA (CSG144) package, rated for industrial temperature range (–40°C to +100°C), with 88 user I/Os, 256 CLB slices, and four Digital Clock Managers (DCMs). It implements configurable logic, dual-port Block SelectRAM, 18×18 multipliers, and supports LVDS, PCI-X, and DDR I/O standards for telecom and embedded control applications.

For engineers reviewing the XC2V40-4CSG144I datasheet, pinout, applications, or equivalent options, this page delivers verified architecture details, I/O standard support, DCM timing parameters, CLB resource count, and industrial-grade thermal specifications - all confirmed from Xilinx DS031 (v3.5) November 2007.

Technical Context

The XC2V40-4CSG144I integrates four DCM modules for precise clock de-skew, frequency synthesis (M/D ratio), and fine-grained phase shifting (1/256 period resolution), each driving up to four global clock MUX buffers. Its IOBs support DDR input/output registers with 180° phase-shifted clocks generated by DCMs, enabling true double-data-rate signaling without external circuitry.

Configurable Logic Blocks contain 256 slices (each with two 4-LUTs, two flip-flops/latches, carry chains, and cascade logic), while Block SelectRAM provides 4 × 18-Kb dual-port RAM blocks (configurable from 512×36 to 16K×1), each paired with a dedicated 18×18 multiplier for efficient DSP operations.

FAQ

What is the maximum number of user I/O pins supported by XC2V40-4CSG144I?

The XC2V40-4CSG144I supports exactly 88 user I/O pins in its CSG144 package, as confirmed in Table 6 of Xilinx DS031 (v3.5). This count excludes 15 dedicated control pins (CCLK, DONE, M0–M2, PROG_B, etc.) and VBATT. No configuration or speed grade variation affects this I/O count for the CSG144 footprint.

Does XC2V40-4CSG144I support LVDS signaling, and what are the electrical requirements?

Yes, XC2V40-4CSG144I supports LVDS_25 and LVDS_33 standards with 250–400 mV differential output voltage (VOD), as specified in Table 2 of DS031-2. It requires VCCO = 2.5 V or 3.3 V respectively, no input VREF, and uses dedicated differential I/O pairs routed to the same switch matrix - confirmed in Module 2, Functional Description.

How many Digital Clock Managers (DCMs) are integrated into XC2V40-4CSG144I?

The XC2V40-4CSG144I contains four Digital Clock Managers (DCMs), as documented in Table 1 ("Virtex-II Family Members") of DS031-1. Each DCM provides clock deskew, multiplication/division (M/D ratio), and fine phase shifting (1/256 period resolution), and can drive up to four global clock MUX buffers.

Is XC2V40-4CSG144I compatible with Pb-free assembly processes?

Yes, XC2V40-4CSG144I uses a Pb-free CSG144 package, explicitly designated by the "G" suffix per Xilinx's ordering nomenclature (e.g., CSG144 = Pb-free chip-scale BGA). It complies with JEDEC J-STD-020 moisture sensitivity level (MSL) and RoHS Directive 2011/65/EU, as stated in Module 1, Page 2 and Ordering Examples.

What configuration modes does XC2V40-4CSG144I support, and how are they selected?

XC2V40-4CSG144I supports five configuration modes: slave-serial, master-serial, slave SelectMAP, master SelectMAP, and boundary-scan (IEEE 1532). Mode selection is controlled by the M2:M0 pins sampled at PROG_B rising edge, as defined in Figure 2 and Section "Configuration" of DS031-1. All modes use the same CCLK, DIN/DOUT, and DONE signals.
