AMD XC5VLX30T-3FFG665C

Overview

XC5VLX30T-3FFG665C from AMD (formerly Xilinx) is a Virtex-5 FPGA featuring 30,816 logic cells, 2.5 Gbps serial transceivers, and embedded Block RAM with 2,448 kbits capacity. It implements high-speed serial I/O in PCIe Gen1 endpoint designs and supports DDR2 memory interfaces up to 533 MHz.

For engineers reviewing the XC5VLX30T-3FFG665C datasheet, pinout, applications, or equivalent options, key selection factors include transceiver compliance (PCIe Gen1), I/O voltage flexibility (1.2V/1.5V/1.8V/2.5V/3.3V), and -3 speed grade timing performance at junction temperatures up to 85°C.

Technical Context

The XC5VLX30T-3FFG665C integrates 12 RocketIO GTP transceivers supporting 1.0–2.5 Gbps line rates, with built-in 8B/10B encoding and elastic buffers. Its SelectIO technology enables source-synchronous interfaces including DDR2 SDRAM and QDR-II SRAM with programmable drive strength and input delay control.

Virtex-5 architecture uses six-input LUTs, dedicated carry logic, and hierarchical clock routing with 16 global clock networks. The device includes 64 DSP48E slices for arithmetic-intensive tasks and supports partial reconfiguration via ICAP interface.

FAQ

What is the maximum supported DDR2 data rate for XC5VLX30T-3FFG665C?

The XC5VLX30T-3FFG665C supports DDR2 SDRAM interfaces up to 533 MHz data rate (266 MHz clock), verified through Xilinx UG190 and characterized across voltage and temperature corners. This capability relies on calibrated I/O delays, on-die termination, and dedicated memory controller IP cores compatible with the device's SelectIO architecture. XC5VLX30T-3FFG665C achieves stable operation using industry-standard DDR2-533 modules with appropriate PCB layout practices.

Does XC5VLX30T-3FFG665C support partial reconfiguration?

Yes, XC5VLX30T-3FFG665C supports partial reconfiguration via the Internal Configuration Access Port (ICAP) and dedicated bitstream partitioning tools in Vivado Design Suite. This allows dynamic replacement of functional modules-such as communication protocol stacks or filter coefficients-without resetting the entire FPGA. XC5VLX30T-3FFG665C requires specific floorplanning and configuration controller logic to manage bitstream loading and handshake signaling.

What transceiver protocols are natively supported by XC5VLX30T-3FFG665C?

XC5VLX30T-3FFG665C natively supports PCIe Gen1 (2.5 Gbps), SATA I/II (1.5/3.0 Gbps), and Serial RapidIO 1.x (1.25/2.5 Gbps) through its 12 RocketIO GTP transceivers. Each transceiver includes 8B/10B encoding, elastic buffers, and clock correction logic. XC5VLX30T-3FFG665C does not support PCIe Gen2 or higher line rates, nor does it implement native Ethernet MAC or Fibre Channel protocols without external PHYs.

What is the purpose of the VCCAUX supply pin on XC5VLX30T-3FFG665C?

The VCCAUX supply pin on XC5VLX30T-3FFG665C delivers 2.5V ±5% to configuration logic, clock management tiles (including DCMs and PLLs), and transceiver reference circuitry. It must be powered before or simultaneously with VCCINT during power-up sequencing. XC5VLX30T-3FFG665C specifies strict monotonic ramp requirements for VCCAUX to ensure reliable configuration and clock initialization, especially under cold-start conditions.

Can XC5VLX30T-3FFG665C operate in industrial temperature range?

No, XC5VLX30T-3FFG665C is rated only for commercial temperature range (0°C to +85°C junction). It lacks qualification for extended industrial (-40°C to +100°C) or automotive temperature grades. For operation outside 0–85°C, thermal derating, enhanced cooling, or alternative Virtex-5 variants such as XC5VLX30T-3FFG665I (industrial grade) must be used. XC5VLX30T-3FFG665C datasheet explicitly defines its thermal limits and derating curves only within the commercial range.
