AMD XCV400-4BG432I

Overview

XCV400-4BG432I from Xilinx is a 2.5 V SRAM-based Field Programmable Gate Array (FPGA) with 468,252 system gates, 10,800 logic cells in a 40×60 CLB array, and 404 user I/O pins in a 432-ball BGA package. It features four delay-locked loops (DLLs), hierarchical memory (including 81,920 bits of block SelectRAM), and supports 66-MHz PCI compliance and hot-swappable Compact PCI operation.

For engineers reviewing the XCV400-4BG432I datasheet, pinout, applications, or equivalent options, this page delivers verified architecture details, I/O banking constraints, DLL jitter specs, CLB-level timing parameters, and migration guidance from Virtex-400 to larger family members.

Technical Context

The XCV400-4BG432I implements a hierarchical routing architecture with General Routing Matrix (GRM), 24 local clock nets, and four primary low-skew global clock distribution networks. Its CLBs contain dual-slice logic cells with 4-input LUTs configurable as 16-bit RAM, 32-bit RAM, 16-bit dual-ported RAM, or 16-bit shift register.

I/O functionality is organized into eight banks with independent VCCO and VREF supply domains; each bank supports mixed standards only if sharing the same VCCO voltage (e.g., LVTTL and SSTL3 at 3.3 V). The device uses a 0.22 μm 5-layer metal CMOS process and includes IEEE 1149.1 boundary-scan logic and a die-temperature sensor diode.

Key Specifications

Pinout & Package

The XCV400-4BG432I is housed in a 432-ball fine-pitch Ball Grid Array (BG432) package with 316 user I/O pins (excluding dedicated clock and configuration pins), organized into eight I/O banks. Each bank has dedicated VCCO and VREF pins; bank-specific voltage assignments govern I/O standard compatibility.

FAQ

What is the maximum operating temperature range for the XCV400-4BG432I?

The XCV400-4BG432I is rated for industrial temperature operation from –40°C to +100°C (junction temperature). This specification is indicated by the "I" suffix in the part number and is validated per DS003-1 (v4.0) Section 3. The device includes an on-die temperature sensor diode for real-time thermal monitoring in mission-critical applications.

Does the XCV400-4BG432I support 5 V-tolerant I/O?

Yes, the XCV400-4BG432I supports 5 V-tolerant inputs for LVTTL, LVCMOS2, and PCI 5 V standards, as confirmed in DS003-2 Table 1. This tolerance is implemented via internal Zener-like clamping to ground and applies only to input buffers - output drivers are not 5 V-tolerant and require VCCO ≤ 3.3 V for those standards.

How many DLLs does the XCV400-4BG432I include, and what are their primary functions?

The XCV400-4BG432I integrates four dedicated delay-locked loops (DLLs), as specified in DS003-1 Features section. These DLLs provide advanced clock control including zero-delay buffering, duty-cycle correction, and phase alignment - essential for synchronizing multiple clock domains in high-speed interfaces such as DDR memory or PCI.

Can the XCV400-4BG432I be configured via JTAG, and what other modes are supported?

Yes, the XCV400-4BG432I supports JTAG configuration (IEEE 1149.1) for programming and boundary-scan testing. Additional modes include master serial (reading config from external PROM), slave serial, and SelectMAP™ parallel configuration - all detailed in DS003-2 Section "Configuration" and validated for XCV400-4BG432I in Module 4 pinout tables.

Is the XCV400-4BG432I still in active production, and what obsolescence status applies?

No - the XCV400-4BG432I is obsolete, as explicitly stated in DS003-1 (v4.0) Revision History: "The products listed in this data sheet are obsolete. See XCN10016 for further information." Aetrix Electronics provides last-time-buy support, extended lifecycle sourcing, and migration path guidance for this discontinued Virtex device.
