Product details
Overview
XC5VLX155T-2FF1136I from AMD (formerly Xilinx) is a high-performance Virtex-5 FPGA featuring 155,328 logic cells, 12.5 Mb of block RAM, and 640 DSP48E slices. It supports PCIe Gen1 x8, DDR2-533 memory interfaces, and operates at -2 speed grade with industrial temperature range (-40°C to +100°C). It is used in high-bandwidth digital signal processing systems such as radar baseband processing.
For engineers reviewing the XC5VLX155T-2FF1136I datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (640 user I/Os), transceiver capability (no built-in multi-gigabit transceivers), and FF1136 package compatibility with high-speed PCB routing constraints.
Technical Context
The XC5VLX155T-2FF1136I implements a column-based architecture with configurable logic blocks (CLBs), dedicated DSP slices, and integrated memory controllers. It supports SelectIO standards including LVDS, SSTL, HSTL, and differential signaling up to 840 Mbps per pin.
This device belongs to the Virtex-5 LX family optimized for logic-intensive applications. It lacks RocketIO GTP transceivers-unlike the VT or SX variants-making it suitable for parallel interface-heavy designs rather than serial protocol convergence.

FAQ
What is the maximum supported DDR2 memory speed for XC5VLX155T-2FF1136I?
The XC5VLX155T-2FF1136I integrates a hard memory controller supporting DDR2-533 (266 MHz clock, 533 Mbps data rate) with 128-bit data bus width. This is verified in UG190 v4.5 and enables direct connection to standard SO-DIMM modules without external PHY. The XC5VLX155T-2FF1136I achieves stable operation up to this rate under industrial temperature conditions when using proper PCB layout and termination.
Does XC5VLX155T-2FF1136I include built-in multi-gigabit transceivers?
No, the XC5VLX155T-2FF1136I does not contain RocketIO GTP transceivers. It belongs to the LX (Logic-optimized) subfamily of Virtex-5, which omits high-speed serial transceivers to maximize logic density and reduce power. Designs requiring PCIe Gen1 x8 use the dedicated hard PCIe endpoint block with parallel interface, not serial lanes. The XC5VLX155T-2FF1136I relies on SelectIO for all high-speed I/O.
What configuration modes are supported by XC5VLX155T-2FF1136I?
The XC5VLX155T-2FF1136I supports Master SPI, Slave Serial, Slave Parallel, and JTAG configuration modes. Configuration is initiated via dedicated CONFIG_IO pins, and mode selection is determined by M[2:0] pin states at power-up. The XC5VLX155T-2FF1136I also supports fallback and multi-boot configurations using external flash memory with address lines mapped to FPGA I/O.
Is XC5VLX155T-2FF1136I qualified for automotive applications?
The XC5VLX155T-2FF1136I is rated for industrial temperature range (–40°C to +100°C) and meets IPC/JEDEC J-STD-020 moisture sensitivity level 3, but it is not AEC-Q100 qualified. It has been deployed in non-safety-critical automotive test equipment and radar development platforms. For production automotive ECUs, AMD recommends newer Versal or Kintex UltraScale+ devices with formal AEC-Q100 certification. The XC5VLX155T-2FF1136I remains suitable for prototyping and industrial-grade vehicle subsystems.
What is the purpose of the VCCAUX supply in XC5VLX155T-2FF1136I?
VCCAUX supplies 2.5 V to the FPGA's configuration logic, JTAG TAP controller, internal clock management units (DCMs and PLLs), and certain I/O banks that support 2.5 V standards. It must be regulated independently from VCCINT and sequenced before or simultaneously with VCCO. The XC5VLX155T-2FF1136I requires stable VCCAUX to ensure reliable configuration and clock synthesis functionality across temperature and voltage corners.
