AMD XC4VLX25-12SF363C

Overview

XC4VLX25-12SF363C from AMD (formerly Xilinx) is a Virtex-4 LX family FPGA with 24,192 logic cells, 1.2V core voltage, -12 speed grade, and 363-pin Fine-Pitch Ball Grid Array (FBGA) package. It integrates SelectIO™ technology, embedded PowerPC™ processors, and high-speed serial transceivers for reconfigurable system-on-chip applications in wired communications infrastructure.

For engineers reviewing the XC4VLX25-12SF363C datasheet, pinout, applications, or equivalent options, key selection criteria include logic density, I/O count (240 user I/Os), differential signaling support (LVDS, RSDS), embedded Block RAM (737,280 bits), and compliance with IEEE 1149.1 JTAG boundary-scan.

Technical Context

The XC4VLX25-12SF363C implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), dedicated DSP slices, and clock management tiles (CMTs) containing DCMs and PLLs. It supports multi-gigabit transceivers up to 3.125 Gbps and includes 12 embedded PowerPC 405 cores in higher-density variants-though this specific LX25 device does not integrate PowerPC cores.

It features SelectIO™ technology supporting 18 I/O standards including LVCMOS, LVTTL, HSTL, SSTL, and differential standards such as LVDS and RSDS. The -12 speed grade guarantees timing closure at 12 ns input setup time and 1.2 V ±3% core supply tolerance under industrial temperature range (0°C to 85°C).

Key Specifications

Pinout & Package

XC4VLX25-12SF363C is housed in a 363-ball fine-pitch BGA (FPBGA) package with exposed thermal pad. Pinout follows Xilinx Virtex-4 LX25 pin assignment specification for SF363 package, including dedicated configuration pins (INIT_B, PROGRAM_B, CCLK), JTAG boundary-scan (TCK/TMS/TDI/TDO), dual-purpose I/O banks, and dedicated global clock inputs (GCLK, GCLK_M2M).

FAQ

What is the maximum operating frequency supported by XC4VLX25-12SF363C?

The XC4VLX25-12SF363C has a -12 speed grade, meaning its worst-case internal propagation delay meets timing closure for system clocks up to 500 MHz in critical paths. Actual achievable frequency depends on design complexity, placement, and routing-but the device's DCMs and PLLs support output frequencies from 1.25 MHz to 500 MHz with jitter <150 ps RMS.

Does XC4VLX25-12SF363C include embedded PowerPC processors?

No, the XC4VLX25-12SF363C is a Virtex-4 LX device and does not integrate PowerPC 405 cores. Only Virtex-4 FX devices (e.g., XC4VFX20) include embedded PowerPC processors. The XC4VLX25-12SF363C provides logic resources, Block RAM, and clock management but relies on external processors for control-plane functions.

What configuration modes are supported by XC4VLX25-12SF363C?

The XC4VLX25-12SF363C supports Master Serial, Slave Serial, Slave Parallel, and JTAG configuration modes. It loads bitstreams from external SPI PROMs (Master Serial), microprocessors (Slave Parallel), or host PCs (JTAG). Configuration is initiated via PROGRAM_B and monitored using INIT_B and DONE signals.

Is XC4VLX25-12SF363C RoHS compliant?

Yes, XC4VLX25-12SF363C is RoHS-6 compliant (lead-free, halogen-free) and meets JEDEC J-STD-020D moisture sensitivity level 3 (MSL3) requirements. The 363-pin FBGA package uses matte tin finish and complies with IPC/JEDEC J-STD-033 handling guidelines.

Can XC4VLX25-12SF363C interface directly with DDR2 SDRAM?

Yes, XC4VLX25-12SF363C supports DDR2 SDRAM interfaces through its SelectIO™ I/O banks configured for SSTL-18 Class I standards. It provides programmable I/O delays, dynamic phase alignment, and source-synchronous capture-enabling reliable 400 Mbps data rates when paired with appropriate memory controller IP.
