Product details
Overview
XC4VLX40-11FFG668I from AMD (formerly Xilinx) is a Virtex-4 LX family FPGA with 41,472 logic cells, 2.5 Gbps multi-gigabit transceivers, and embedded PowerPC 405 cores. It features 2,016 Kbits of block RAM, 128 DSP48 slices, and operates at -11 speed grade with industrial temperature range (-40°C to +100°C). Used in high-performance reconfigurable computing and protocol bridging systems.
For engineers reviewing the XC4VLX40-11FFG668I datasheet, pinout, applications, or equivalent options, key selection factors include I/O count (448 user I/Os), transceiver compliance (Xilinx SelectIO™ and RocketIO™), power supply sequencing requirements, and configuration interface options (Master Serial, Slave SelectMAP).
Technical Context
The XC4VLX40-11FFG668I implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), dedicated DSP48 slices for arithmetic-intensive tasks, and integrated RocketIO™ transceivers supporting protocols including PCI Express Gen1 and Gigabit Ethernet. Its dual-register LUT-based logic enables high-speed synchronous design.
Configuration is performed via internal Spartan-3 compatible PROM or external serial/parallel mode using JTAG, with bitstream encryption support. The device supports partial reconfiguration and dynamic reconfiguration through dedicated ICAP interface, enabling runtime hardware updates without system reset.

FAQ
What is the maximum supported I/O standard voltage for XC4VLX40-11FFG668I?
XC4VLX40-11FFG668I supports I/O voltages from 1.2 V to 3.3 V per bank, with individual bank configuration. Each I/O bank's VCCO must match the selected standard (e.g., 1.8 V for SSTL18, 2.5 V for HSTL_I). The device does not support 1.0 V or 3.6 V operation, and mixing incompatible standards within one bank is prohibited.
Does XC4VLX40-11FFG668I support JTAG boundary-scan testing?
Yes, XC4VLX40-11FFG668I fully complies with IEEE 1149.1 (JTAG) and supports boundary-scan testing via TDI, TDO, TMS, TCK, and TRST pins. The BSCAN_VIRTEX4 primitive enables access to internal logic states, and the device supports INTEST, EXTEST, and SAMPLE instructions for PCB-level diagnostics.
Can XC4VLX40-11FFG668I be configured using SPI flash memory?
No, XC4VLX40-11FFG668I does not natively support SPI flash configuration. It requires x8 or x16 parallel NOR flash (SelectMAP mode) or serial PROM (Master Serial mode using Xilinx Platform Flash XL). SPI interface support was introduced in later Virtex-5 and newer families.
What is the configuration bitstream size for XC4VLX40-11FFG668I?
The uncompressed configuration bitstream for XC4VLX40-11FFG668I is approximately 5.2 Mbits for full device programming. With Xilinx BitGen compression enabled, typical compressed size is ~2.8 Mbits. Bitstream format is proprietary and requires Xilinx ISE 14.7 or earlier toolchain for generation and validation.
Is XC4VLX40-11FFG668I qualified for automotive AEC-Q100?
No, XC4VLX40-11FFG668I is rated for industrial temperature range (-40°C to +100°C) and is not AEC-Q100 qualified. Xilinx did not release any Virtex-4 devices under automotive qualification; automotive-grade alternatives require evaluation of Spartan-3A DSP or later Zynq-7000 series with formal AEC-Q100 certification.
