AMD XCV400E-6PQ240C

Overview

XCV400E-6PQ240C from Xilinx is a 1.8 V SRAM-based Field Programmable Gate Array with 569,952 system gates, 10,800 logic cells, and 40 block RAMs (163,840 bits). It features eight digital Delay-Locked Loops (DLLs), supports LVDS/BLVDS/LVPECL differential I/O up to 622 Mb/s, and delivers internal performance up to 130 MHz (four LUT levels). It is used in high-speed communication interface design requiring PCI-compliant 33/66-MHz operation.

For engineers reviewing the XCV400E-6PQ240C datasheet, pinout, applications, or equivalent options, this device serves as a high-density, low-power FPGA for source-synchronous data transmission, DDR memory interfacing, and clock-domain bridging in telecom and test equipment.

Technical Context

The XCV400E-6PQ240C implements a regular array architecture of Configurable Logic Blocks (CLBs) and Input/Output Blocks (IOBs), interconnected via a General Routing Matrix (GRM) and VersaRing I/O routing. Each CLB contains four logic cells with 4-input LUTs, dedicated carry chains, and dual flip-flops per slice with independent clock enable and synchronous/asynchronous set/reset.

Its IOBs support 20 interface standards-including LVTTL, LVCMOS2, SSTL3, HSTL, and differential LVDS-with banked VCCO and VREF management. Eight DLLs provide zero-delay clock conversion, 50% duty-cycle synthesis for DDR, and frequency multiplication up to 4×, enabling precise timing control across multiple I/O banks and internal logic domains.

FAQ

What is the maximum differential I/O pair count supported by XCV400E-6PQ240C?

XCV400E-6PQ240C supports up to 183 differential I/O pairs in the PQ240 package. This enables high-bandwidth differential signaling such as LVDS at 622 Mb/s across multiple parallel channels. The count is fixed per device/package combination and verified in Table 3 of DS022-1 (v2.3).

Does XCV400E-6PQ240C support true dual-port block RAM?

Yes, XCV400E-6PQ240C includes 40 block RAMs, each configured as a true dual-port 4096-bit memory with independent read/write addresses, clocks, and enables per port. This capability is documented in DS022-2 (v2.8) Section "Block SelectRAM" and enables concurrent access for FIFOs and memory-mapped peripherals.

What clock management resources are integrated into XCV400E-6PQ240C?

XCV400E-6PQ240C integrates eight fully digital Delay-Locked Loops (DLLs). These provide clock multiply/divide, 50% duty-cycle synthesis for DDR, zero-delay conversion of LVPECL/LVDS inputs, and phase alignment across multiple clock domains-key for source-synchronous interfaces and multi-rate systems.

Is XCV400E-6PQ240C pin-compatible with other Virtex-E devices in PQ240 packaging?

XCV400E-6PQ240C shares the same PQ240 footprint with XCV50E through XCV300E variants, but not with XCV600E+ due to differing I/O counts and bank assignments. Pin compatibility is confirmed in DS022-1 Table 3 and Module 4 pinout diagrams; however, VCCO/VREF pin allocations vary by device size.

What is the core supply voltage requirement for XCV400E-6PQ240C?

XCV400E-6PQ240C requires a 1.8 V ±3% supply on VCCINT for internal logic and memory operation. This lower voltage versus prior Virtex families reduces dynamic power while maintaining performance, and is specified in DS022-3 DC Characteristics tables.
