Product details
Overview
XC4VSX55-11FFG1148I from AMD is a Virtex-4 SX family FPGA featuring 55,296 logic cells, 3.2 Mb of block RAM, and 240 DSP48 slices, configured in a 1148-pin Flip-Chip Fine-Pitch Ball Grid Array (FC-FBGA) package for high-performance embedded processing and digital signal processing applications.
For engineers reviewing the XC4VSX55-11FFG1148I datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (720 user I/Os), speed grade (-11), extended temperature range (-40°C to +100°C), and support for SelectIO™ standards including LVDS, SSTL, and HSTL.
Technical Context
The XC4VSX55-11FFG1148I implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), dedicated DSP48 slices for multiply-accumulate operations, and flexible clock management using Digital Clock Managers (DCMs). It supports multi-gigabit transceivers only in FX and FX/LX families-not in SX series-so this device lacks native SerDes.
It integrates 24 RocketIO™ GTP transceivers in Virtex-4 FX variants, but the SX variant-including XC4VSX55-11FFG1148I-excludes transceivers entirely. Configuration is performed via Master SelectMAP, Slave SelectMAP, or JTAG, with support for bitstream encryption and fallback configuration modes.

FAQ
What is the maximum operating frequency of the XC4VSX55-11FFG1148I?
The XC4VSX55-11FFG1148I carries the -11 speed grade, the highest bin for the Virtex-4 SX family, supporting system clock frequencies up to 500 MHz in typical conditions. Internal DCM outputs can reach 1 GHz via frequency synthesis, but actual achievable frequency depends on design placement, routing, and I/O standard constraints.
Does the XC4VSX55-11FFG1148I include built-in transceivers?
No, the XC4VSX55-11FFG1148I does not include multi-gigabit transceivers. Transceiver capability is exclusive to the Virtex-4 FX and FX/LX families. The SX variant focuses on logic and DSP resources, making the XC4VSX55-11FFG1148I appropriate for parallel processing rather than high-speed serial I/O.
What configuration methods are supported by the XC4VSX55-11FFG1148I?
The XC4VSX55-11FFG1148I supports three primary configuration modes: Master SelectMAP (using onboard oscillator), Slave SelectMAP (driven by external controller), and IEEE 1149.1 JTAG. It also enables fallback configuration and bitstream encryption using AES-128 keys loaded via JTAG or configuration pins.
Is the XC4VSX55-11FFG1148I suitable for aerospace applications?
Yes, the XC4VSX55-11FFG1148I is rated for industrial temperature range (–40°C to +100°C) and has been used in DO-254-compliant avionics systems. Its radiation tolerance characteristics-documented in Xilinx reliability reports-and robust configuration security make it suitable for non-mission-critical aerospace subsystems.
How many block RAMs does the XC4VSX55-11FFG1148I contain?
The XC4VSX55-11FFG1148I contains 288 block RAMs, each 18 kb in size, totaling 3.2 Mb of on-chip memory. These RAMB16 blocks support true dual-port operation, byte-write enable, and programmable parity, enabling efficient implementation of large FIFOs, caches, and frame buffers in the XC4VSX55-11FFG1148I.
