AMD XCV400-5HQ240I

Overview

XCV400-5HQ240I from Xilinx is a 2.5 V SRAM-based Field Programmable Gate Array (FPGA) with 468,252 system gates, 10,800 logic cells, and 404 maximum user I/O pins in a 240-pin High Heat Dissipation Quad Flat Pack (HQ240) package. It features four delay-locked loops (DLLs), hierarchical memory (including 81,920-bit block RAM and LUT-based RAM/shift registers), and supports 66-MHz PCI compliance for high-speed embedded control and interface bridging applications.

For engineers reviewing the XCV400-5HQ240I datasheet, pinout, applications, or equivalent options, this page delivers verified architecture details, I/O banking constraints, CLB-level timing behavior, SelectIO™ standard compatibility (LVTTL, HSTL, SSTL), and industrial-temperature (-40°C to +100°C) operation confirmed for the HQ240 package variant.

Technical Context

The XCV400-5HQ240I implements a regular array of Configurable Logic Blocks (CLBs), each containing two slices with four 4-input LUTs, dedicated carry chains, and dual flip-flops per slice. Its routing hierarchy includes local VersaBlock interconnect, global General Routing Matrix (GRM), 12 horizontal/vertical Longlines, and peripheral VersaRing I/O routing for pin-locking flexibility.

It integrates 20 block SelectRAM™ modules (each 4k-bit synchronous dual-ported RAM), supports eight I/O banks with independent VCCO/VREF assignment, and provides IEEE 1149.1 boundary-scan testability. The -5 speed grade guarantees 5.0 ns register-to-register delay and 200 MHz system clock performance under worst-case industrial conditions.

FAQ

What is the maximum operating temperature range for XCV400-5HQ240I?

The XCV400-5HQ240I is rated for industrial temperature operation from –40°C to +100°C junction temperature. This specification is confirmed in the Virtex ordering information (DS003-1, Figure 1) and applies specifically to the "I" suffix variant in the HQ240 package. Thermal derating is not required within this range, and the die-temperature sensor diode enables real-time monitoring in deployed systems.

Does XCV400-5HQ240I support 5 V-tolerant I/O standards?

Yes, XCV400-5HQ240I supports 5 V-tolerant I/O standards including LVTTL and PCI 5 V, as documented in Table 1 of DS003-2. This tolerance is implemented via Zener-like clamping to ground and applies only to inputs-not outputs-and is valid only when VCCO is set to 3.3 V. It does not extend to SSTL or HSTL standards, which require strict VCCO matching.

How many block RAM modules are integrated in XCV400-5HQ240I?

XCV400-5HQ240I contains 20 block SelectRAM™ modules, totaling 81,920 bits of synchronous dual-ported memory. Each module is 4,096 bits and configurable as various depth/width combinations (e.g., 256×16, 512×8). This count is explicitly listed in Table 3 of DS003-2 and is fixed for the XCV400 device regardless of package or speed grade.

Can XCV400-5HQ240I be configured in slave serial mode?

Yes, XCV400-5HQ240I supports slave serial configuration mode, where an external controller drives the CCLK and DIN pins to load the configuration bitstream. This mode is detailed in DS003-2 Section "Configuration Modes" and requires proper initialization sequencing via PROGRAM_B and INIT_B signals. It is commonly used in systems with microcontroller-based configuration managers.

What I/O banking constraints apply to XCV400-5HQ240I in the HQ240 package?

In the HQ240 package, XCV400-5HQ240I has eight I/O banks (Bank 0–7), each requiring its own VCCO voltage and, if needed, a shared VREF. All VCCO pins in HQ240 are internally bonded, so a single VCCO voltage must be applied across all banks-limiting mixed-voltage I/O to standards sharing the same VCCO (e.g., LVTTL and SSTL3 both at 3.3 V).
