AMD XCV50E-6CS144I

Overview

XCV50E-6CS144I from Xilinx is a 1.8 V SRAM-based Field Programmable Gate Array with 20,736 logic cells, 176 user I/O pins in a 144-pin CSOP package, and eight digital Delay-Locked Loops (DLLs) supporting 240 MHz system clocking and 622 Mb/s LVDS I/O for high-speed communications infrastructure.

For engineers reviewing the XCV50E-6CS144I datasheet, pinout, applications, or equivalent options, this device serves as a production-grade, industrial-temperature (-40°C to +100°C) FPGA optimized for PCI-compliant 33/66 MHz interfaces, synchronous memory controllers (200 MHz ZBT SRAM, DDR SDRAM), and source-synchronous data transmission architectures requiring deterministic timing control via DLL-based clock management.

Technical Context

The XCV50E-6CS144I implements a regular array architecture of Configurable Logic Blocks (CLBs), each containing four 4-input LUTs with dedicated carry chains and dual flip-flops per slice, enabling high-speed arithmetic and wide-input logic functions. It integrates 16 block RAMs (65,536 bits total) and 24,576 bits of distributed RAM, all operating at up to 250 MHz.

Its IOB structure supports 20 I/O standards-including LVTTL, LVCMOS2, SSTL3, HSTL, LVDS, and LVPECL-with banked VCCO and VREF domains, independent programmable drive strength (up to 48 mA sink), slew rate control, and IEEE 1149.1 boundary-scan. All I/O pins are 3 V tolerant; 5 V tolerance requires external 100 Ω resistors.

Manufacturer

Xilinx, now part of AMD, pioneered FPGA technology and developed the Virtex family as high-performance programmable logic solutions for demanding compute, connectivity, and signal processing applications.

The Virtex-E product line was designed specifically for applications requiring PCI compliance, high-bandwidth memory interfacing (ZBT/DDR), and source-synchronous I/O at speeds up to 622 Mb/s-targeting communications infrastructure, test equipment, and industrial automation.

FAQ

What is the maximum operating junction temperature for XCV50E-6CS144I?

The XCV50E-6CS144I is rated for industrial temperature operation with a junction temperature range of –40°C to +100°C. This specification is defined in the DS022-1 Production Product Specification and validated across all speed grades and package variants. Thermal design must ensure sustained operation within this envelope using appropriate heatsinking and airflow for the CS144 ceramic package.

Does XCV50E-6CS144I support LVPECL clock inputs?

Yes, XCV50E-6CS144I supports LVPECL clock inputs up to 300+ MHz through dedicated global clock pins (GCLK0–GCLK3), as confirmed in DS022-1 Section "Differential Signalling Support". These inputs are compatible with standard LVPECL drivers and require AC-coupling and proper termination to 50 Ω to meet setup/hold timing requirements.

How many block RAMs does XCV50E-6CS144I contain?

XCV50E-6CS144I contains 16 block RAMs totaling 65,536 bits, as specified in Table 1 and Table 4 of DS022-2. Each block is a true dual-port 4096-bit RAM with independent read/write addressing, enabling simultaneous access for applications like ping-pong buffering or FIFO implementation without CLB resource consumption.

Is XCV50E-6CS144I pin-compatible with other Virtex-E devices in the CS144 package?

No-XCV50E-6CS144I is not pin-compatible with larger Virtex-E devices (e.g., XCV100E-6CS144I) in the same CS144 package. While both share the 144-pin footprint, Table 3 in DS022-1 shows differing I/O counts (176 vs. 196) and distinct pin assignments for VCCO/VREF banks, making direct substitution impossible without PCB revision.

What configuration modes are supported by XCV50E-6CS144I?

XCV50E-6CS144I supports master serial, slave serial, SelectMAP™, and IEEE 1149.1 JTAG configuration modes, as documented in DS022-2 Section "Configuration Data Loading". JTAG is used for boundary-scan testing and in-system programming; SelectMAP™ enables high-speed parallel configuration from microprocessors or flash memory.
