Product details
Overview
XC5VLX20T-3FFG323C from AMD (formerly Xilinx) is a Virtex-5 FPGA featuring 20,736 logic cells, 1.2 MB of block RAM, 120 DSP48E slices, and operates at -3 speed grade with 1.0 V core voltage. It is housed in a 323-pin Fine-Pitch Flip-Chip BGA (FFG323) package and targets high-performance embedded vision and industrial protocol bridging applications.
For engineers reviewing the XC5VLX20T-3FFG323C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (240 user I/Os), differential signaling support (LVDS, RSDS), multi-gigabit transceiver availability (no GTX transceivers in LX20T), and thermal design implications of the FFG323 package.
Technical Context
The XC5VLX20T-3FFG323C belongs to the Virtex-5 LXT family's "T" (Transceiver) variant - however, this specific LX20T device contains zero GTX transceivers. It implements a column-based architecture with dedicated clock routing, SelectIO technology supporting 240 user-configurable I/Os across 12 banks, and integrated PCI Express® Endpoint v1.0 logic.
It supports configuration via Master SelectMAP, Slave SelectMAP, and JTAG interfaces, and includes System Monitor functionality for on-chip temperature and supply voltage monitoring. The -3 speed grade guarantees timing closure up to 550 MHz for internal logic paths under specified conditions.

FAQ
Does XC5VLX20T-3FFG323C include multi-gigabit transceivers?
No, XC5VLX20T-3FFG323C does not contain any GTX transceivers. Although it belongs to the Virtex-5 LXT family naming convention, the LX20T variant is transceiver-less. Designers requiring serial transceivers must select an LXT part with non-zero GTX count (e.g., XC5VLX50T) or use external SerDes ICs alongside XC5VLX20T-3FFG323C.
What configuration modes does XC5VLX20T-3FFG323C support?
XC5VLX20T-3FFG323C supports Master SelectMAP, Slave SelectMAP, and JTAG configuration modes. Master SelectMAP uses internal oscillator and CCLK output for parallel PROM loading; Slave SelectMAP allows external controller to drive configuration; JTAG is used for boundary-scan testing and programming via standard debug probes.
Is XC5VLX20T-3FFG323C RoHS compliant and lead-free?
Yes, XC5VLX20T-3FFG323C is RoHS compliant and lead-free. The FFG323 package uses matte tin finish on solder balls and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3), requiring bake conditioning before reflow if exposed beyond floor life.
Can XC5VLX20T-3FFG323C be used as a PCI Express endpoint in x4 or x8 mode?
No, XC5VLX20T-3FFG323C supports only x1 lane PCI Express Endpoint v1.0. Its hard IP block is fixed to single-lane operation and cannot be scaled to x4 or x8. For wider PCIe lanes, designers must select higher-density Virtex-5 LXT devices such as XC5VLX110T or migrate to Virtex-6 or newer families.
What is the maximum operating junction temperature for XC5VLX20T-3FFG323C?
The maximum operating junction temperature for XC5VLX20T-3FFG323C is 100°C, as specified in the Virtex-5 DC and Switching Characteristics datasheet (DS106). Thermal design must ensure junction temperature remains below this limit under worst-case power dissipation and ambient conditions.
