AMD XCV50-4PQ240I

Overview

XCV50-4PQ240I from Xilinx is a 2.5 V SRAM-based Field Programmable Gate Array (FPGA) with 57,906 system gates, 1,728 logic cells in a 16×24 CLB array, and 166 user I/O pins in a 240-pin Plastic Quad Flat Pack (PQFP) package. It features four delay-locked loops (DLLs), hierarchical memory resources including distributed LUT RAM and 32,768-bit block SelectRAM, and supports 66-MHz PCI-compliant interfaces for industrial control and communications infrastructure.

For engineers reviewing the XCV50-4PQ240I datasheet, pinout, applications, or equivalent options, this page delivers verified architecture details, I/O banking constraints, DLL jitter specifications, CLB timing parameters, and migration guidance from Virtex-1 generation devices.

Technical Context

The XCV50-4PQ240I implements a hierarchical routing architecture with General Routing Matrix (GRM), local VersaBlock interconnect, and peripheral VersaRing I/O routing - enabling pin-locking and PCB layout reuse across logic revisions. Its CLBs contain two slices each with four 4-input LUTs, dedicated carry chains, F5/F6 multiplexers for 5–19 input functions, and dual-port synchronous storage elements.

Each IOB supports 16 SelectIO™ standards including LVTTL, LVCMOS2, PCI 3.3 V, HSTL Class IV, and SSTL2/3, with banked VCCO (1.5 V / 2.5 V / 3.3 V) and VREF (0.75–1.5 V) constraints. Four DLLs provide clock deskew and phase alignment across global clock nets, while IEEE 1149.1 boundary-scan ensures testability.

FAQ

Is XCV50-4PQ240I still in production or considered obsolete?

XCV50-4PQ240I is marked as obsolete per Xilinx documentation (DS003-1 v4.0, March 2013) and is no longer manufactured. However, Aetrix Electronics maintains legacy inventory with full traceability and offers lifecycle management support, including obsolescence forecasting and last-time-buy coordination for ongoing production programs.

What configuration modes does XCV50-4PQ240I support?

XCV50-4PQ240I supports four configuration modes: Master Serial (reads bitstream from external PROM via CCLK), Slave Serial (receives bitstream from microcontroller), SelectMAP™ (8-bit parallel interface), and JTAG (boundary-scan programming). All modes retain full functionality, though JTAG is preferred for debug and field updates due to its standardized interface.

Can XCV50-4PQ240I operate with mixed I/O standards on the same package?

Yes, but only within I/O banking constraints: each of the eight banks must use a single VCCO voltage and, if applicable, one shared VREF. For example, HSTL Class I (1.5 V VCCO, 0.75 V VREF) and GTL (no VCCO dependency) may coexist in Bank 0, but LVTTL (3.3 V VCCO) must be isolated in a separate bank with dedicated VCCO pins.

Does XCV50-4PQ240I include on-chip temperature sensing?

Yes, XCV50-4PQ240I integrates a die-temperature sensor diode as specified in DS003-1. This analog element requires external biasing and measurement circuitry (e.g., constant-current source and ADC) to derive junction temperature - used for thermal monitoring and dynamic clock throttling in industrial deployments.

What is the maximum operating frequency of the DLLs in XCV50-4PQ240I?

The four DLLs in XCV50-4PQ240I operate up to 200 MHz input frequency with jitter performance of <50 ps (typical) and <150 ps (worst-case) per DS003-3. They lock within 100 μs and support phase-shifted outputs for source-synchronous interfaces like DDR SDRAM controllers.
