AMD XCV400E-8BG432C

Overview

XCV400E-8BG432C from Xilinx is a 1.8 V SRAM-based Field Programmable Gate Array (FPGA) with 569,952 system gates and 10,800 logic cells in a 40 × 60 CLB array. It delivers 130 MHz internal performance (four LUT levels), supports up to 404 user I/O pins in BG432 package, and integrates eight digital Delay-Locked Loops (DLLs) for clock management. It is used in high-speed communication interfaces requiring PCI-compliant 33/66 MHz operation and LVDS/LVPECL signaling.

For engineers reviewing the XCV400E-8BG432C datasheet, pinout, applications, or equivalent options, this page provides verified technical context, confirmed I/O banking rules, real-world timing performance data (e.g., 4.6 ns 16:1 multiplexer delay), exact block RAM configuration (40 × 4096-bit blocks = 163,840 bits), and validated alternatives for migration from Virtex-E family designs.

Technical Context

The XCV400E-8BG432C implements a regular FPGA architecture with configurable logic blocks (CLBs), input/output blocks (IOBs), and a general routing matrix (GRM). Each CLB contains four logic cells (LCs), each with a 4-input LUT, carry logic, and a D-flip-flop; two slices per CLB support F5/F6 multiplexing for 5–6 input functions and arithmetic chains.

Its IOBs support 20 interface standards including LVTTL, LVCMOS2, SSTL3, HSTL, PCI33_3/PCI66_3, LVDS, BLVDS, and LVPECL - with I/O banks requiring shared VCCO (e.g., 3.3 V for PCI/LVTTL) and optional VREF (e.g., 1.5 V for SSTL3). Eight DLLs provide zero-delay clock conversion, 50% duty cycle synthesis for DDR, and 4× frequency multiplication.

FAQ

What is the maximum differential I/O pair count supported by XCV400E-8BG432C?

XCV400E-8BG432C supports up to 183 differential I/O pairs, as confirmed in Table 1 of DS022-1 (v2.3). This value is fixed for the XCV400E device regardless of package; the BG432 variant realizes 404 total user I/O pins, with differential pairing constrained by bank layout and VCCO/VREF allocation per DS022-4 pinout documentation.

Does XCV400E-8BG432C support 5 V tolerant I/O?

No, XCV400E-8BG432C does not support native 5 V tolerant I/O. Its I/O pins are 3 V tolerant, and can be made 5 V tolerant only with an external 100 Ω series resistor per pin, as specified in DS022-1 Section "Virtex-E Compared to Virtex Devices". PCI 5 V operation is explicitly unsupported.

How many DLLs are integrated into XCV400E-8BG432C and what are their key capabilities?

XCV400E-8BG432C integrates eight fully digital Delay-Locked Loops (DLLs), as stated in DS022-1 Features section and confirmed in Module 2 architectural description. Each DLL supports clock multiply/divide, 50% duty cycle synthesis for DDR, zero-delay conversion of LVPECL/LVDS clocks, and easier clock mirroring versus Virtex-family DLLs.

Is XCV400E-8BG432C pin-compatible with other Virtex-E devices in BG432 package?

Yes, XCV400E-8BG432C is pin-compatible with other Virtex-E devices offered in BG432 package (e.g., XCV300E-8BG432C, XCV600E-8BG432C), as noted in DS022-1 "Virtex-E Compared to Virtex Devices" section. Minor exceptions exist and are documented in DS022-4 Pinout Tables, but mechanical and electrical pin mapping remains consistent across the BG432 footprint.

What is the block RAM configuration of XCV400E-8BG432C and how is it structured?

XCV400E-8BG432C contains 40 block SelectRAM units, each 4096 bits, totaling 163,840 bits, as listed in Table 4 of DS022-2. Each block is true dual-port synchronous RAM with independent address/data/control per port, organized in columns adjacent to CLB arrays per Table 3 column location mapping.
