AMD XC2V4000-5BF957I

Overview

XC2V4000-5BF957I from Xilinx is a high-density Virtex-II platform FPGA with 4 million system gates, 23,040 configurable logic blocks (CLBs), 120 Digital Clock Manager (DCM) modules, and 912 user I/Os in a flip-chip BGA package. It delivers 420 MHz internal clock speed and supports LVDS, DDR, PCI-X, and HSTL I/O standards for telecom, networking, and video processing systems.

For engineers reviewing the XC2V4000-5BF957I datasheet, pinout, applications, or equivalent options, this device is evaluated for high-speed serial interface implementation, embedded DSP acceleration, clock domain crossing with DCM-based phase alignment, and multi-standard I/O interfacing in industrial-grade temperature environments (–40°C to +100°C).

Technical Context

The XC2V4000-5BF957I implements a hierarchical architecture with 80 × 72 CLB array, 120 dedicated 18-bit × 18-bit multipliers, and 120 block SelectRAM™ modules (each 18 Kb dual-port RAM). Its IOBs support DDR input/output registers with independent clock enables and programmable sink current (2–24 mA) per I/O.

Digital Clock Manager (DCM) modules provide precise de-skew, frequency synthesis (M/D ratio), and fine-grained phase shifting (1/256 clock period resolution). The flip-chip BF957 package enables 684 total I/O pins - including 912 user I/Os - with on-die Digitally Controlled Impedance (DCI) termination for single-ended standards like HSTL and SSTL.

Key Specifications

Pinout & Package

The XC2V4000-5BF957I uses a flip-chip BGA package (BF957) with 957 balls, 1.27 mm pitch, and 40 mm × 40 mm body size. It supports 912 user I/Os plus 15 dedicated configuration and boundary-scan 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 junction temperature for XC2V4000-5BF957I?

The XC2V4000-5BF957I is rated for industrial temperature range operation with a maximum junction temperature of +100°C. This specification is guaranteed across all speed grades and I/O configurations defined in DS031 (v3.5), and applies to continuous operation under specified voltage and thermal conditions. The -5 speed grade maintains timing performance up to this limit.

Does XC2V4000-5BF957I support JTAG boundary-scan testing?

Yes, XC2V4000-5BF957I fully supports IEEE 1149.1 boundary-scan testing via dedicated TCK, TMS, TDI, and TDO pins. It implements EXTEST, INTEST, and HIGHZ instructions, and supports BYPASS, PRELOAD, SAMPLE, IDCODE, and USERCODE non-test operations. The boundary-scan chain is factory-tested and accessible during both configuration and normal operation.

Can XC2V4000-5BF957I be configured via slave serial mode?

Yes, XC2V4000-5BF957I supports five configuration modes including slave serial mode. In this mode, an external master device (e.g., microcontroller or processor) drives the CCLK signal and shifts configuration data into the device through the DIN pin. Mode pins M0–M2 must be set to '010' to select slave serial operation, and DONE goes high upon successful configuration completion.

What I/O standards with on-chip termination does XC2V4000-5BF957I support?

XC2V4000-5BF957I supports Digitally Controlled Impedance (DCI) for 22 I/O standards including LVDCI_33, HSTL_I_DCI, SSTL3_I_DCI, and LVDS_25_DCI. DCI provides programmable on-die series or split termination matching standard reference resistors (e.g., 50 Ω, 75 Ω), eliminating external termination components and improving signal integrity for high-speed interfaces.

Is bitstream encryption supported on XC2V4000-5BF957I?

Yes, XC2V4000-5BF957I includes hardware-accelerated Triple-DES encryption for configuration bitstreams. One or two DES key sets can be stored in on-chip non-volatile memory, enabling secure configuration loading and readback protection. This feature is enabled via configuration bit settings and requires no external crypto controller - the XC2V4000-5BF957I decrypts the bitstream internally during startup.
