AMD XCV50-4CS144I

Overview

XCV50-4CS144I 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 94 user I/O pins in a 144-ball chip-scale package. It features four delay-locked loops (DLLs), supports 66-MHz PCI compliance, operates across –40°C to +100°C industrial temperature range, and delivers up to 200 MHz system performance for high-speed digital signal processing and embedded control applications.

For engineers reviewing the XCV50-4CS144I datasheet, pinout, applications, or equivalent options, this page provides verified architecture details, I/O banking constraints, SelectIO™ interface compatibility, block RAM configuration options, and industrial-grade timing specifications - all confirmed for the exact CS144 package and -4 speed grade.

Technical Context

The XCV50-4CS144I implements a hierarchical routing architecture with a General Routing Matrix (GRM), local VersaBlock interconnect, and peripheral VersaRing I/O routing. Its CLBs contain four logic cells each, with dedicated carry chains per slice and F5/F6 multiplexers enabling 5- and 6-input logic functions.

Each IOB supports dual-edge-triggered flip-flops with independent clock enable and synchronous/asynchronous set/reset, while block SelectRAM provides 32,768 bits of dual-ported 4k-bit RAM organized in eight 4096-bit blocks - configurable for independent port widths from 1-bit to 16-bit.

FAQ

What is the maximum operating frequency supported by XCV50-4CS144I?

XCV50-4CS144I supports synchronous system clock rates up to 200 MHz, including I/O timing. This is achievable under worst-case industrial conditions (-40°C to +100°C) with proper PCB layout and power delivery. The -4 speed grade guarantees 5.0 ns register-to-register delay, enabling robust timing closure for designs targeting 150–180 MHz functional clocks in typical implementations.

Does XCV50-4CS144I support hot-swap operation in Compact PCI systems?

Yes, XCV50-4CS144I is explicitly designed for hot-swappable Compact PCI applications. Its I/O architecture meets Compact PCI hot-swap electrical requirements, and its configuration circuitry supports safe insertion/removal while the backplane remains powered. The device's 2.5 V core voltage and 3.3 V tolerant I/O simplify interface with Compact PCI power management controllers.

How many block RAMs does XCV50-4CS144I include, and what configurations are supported?

XCV50-4CS144I includes eight 4096-bit block SelectRAMs totaling 32,768 bits. Each block is fully synchronous and dual-ported, supporting independent read/write operations. Port widths are configurable from 1-bit to 16-bit (e.g., 16×256, 8×512, 4×1024), enabling flexible FIFO depth/width trade-offs and memory-mapped peripheral interfacing without external SRAM.

Can XCV50-4CS144I interface directly with 5 V TTL logic?

XCV50-4CS144I supports 5 V-tolerant inputs for LVTTL, LVCMOS2, and PCI 5 V standards, allowing direct connection to 5 V outputs without level shifters. However, its outputs are not 5 V capable - they operate at VCCO (2.5 V or 3.3 V). For bidirectional 5 V interfacing, external bus switches or level translators are required on output paths.

Is XCV50-4CS144I still in production, and what is its obsolescence status?

XCV50-4CS144I is marked as obsolete per Xilinx documentation (DS003-1 v4.0, March 2013). While no longer manufactured, Aetrix Electronics maintains legacy inventory and provides lifecycle coordination support - including cross-reference guidance, last-time-buy planning, and migration paths to newer Virtex or Kintex families where functionally appropriate.
