AMD XC4VLX40-10FFG1148I

Overview

XC4VLX40-10FFG1148I from AMD (formerly Xilinx) is a Virtex-4 LX family FPGA featuring 41,472 logic cells, 2.5 Gbps multi-gigabit transceivers, and embedded PowerPC 405 cores. It implements high-speed serial I/O, DSP-intensive signal processing, and system-on-chip integration in telecom infrastructure and military-grade reconfigurable computing.

For engineers reviewing the XC4VLX40-10FFG1148I datasheet, pinout, applications, or equivalent options, key selection criteria include I/O voltage support (1.2 V to 3.3 V), -10 speed grade timing performance, FFG1148 flip-chip BGA package compatibility, and compliance with IEEE 1149.1 JTAG boundary-scan.

Technical Context

The XC4VLX40-10FFG1148I integrates 128 block RAMs (each 18 Kbits), 128 dedicated DSP48 slices for multiply-accumulate operations, and up to 640 user I/Os. Its architecture supports partial reconfiguration and includes SelectIO technology with programmable slew rate and drive strength control.

It features dual-register flip-flops per slice, carry logic for high-speed arithmetic, and clock management tiles with DCMs supporting phase shifting, frequency synthesis, and duty cycle correction across four independent clock domains.

Key Specifications

Pinout & Package

XC4VLX40-10FFG1148I uses a 1148-pin flip-chip fine-pitch BGA (FFG) package with 35 × 35 mm body size, 1.0 mm ball pitch, and Pb-free (RoHS-compliant) solder balls. Thermal pad under die improves power dissipation for sustained 1.2 V core operation.

FAQ

What is the core voltage requirement for XC4VLX40-10FFG1148I?

The XC4VLX40-10FFG1148I requires a tightly regulated 1.2 V ±3% core supply (VCCINT) to ensure reliable operation of its 41,472 logic cells and internal interconnect. Deviation beyond this range risks timing violation or configuration loss. Decoupling must meet Xilinx UG070 recommendations using 10 µF bulk and 0.1 µF ceramic capacitors per power rail.

Does XC4VLX40-10FFG1148I support partial reconfiguration?

Yes, XC4VLX40-10FFG1148I supports hardware-accelerated partial reconfiguration via Xilinx ISE tools and BITGEN flow. This allows dynamic replacement of logic modules-such as protocol engines or filter coefficients-without resetting the entire device or disrupting active I/O channels.

What JTAG standard does XC4VLX40-10FFG1148I comply with?

XC4VLX40-10FFG1148I complies with IEEE 1149.1 (JTAG) for boundary-scan testing and in-system programming. Its dedicated TAP controller supports instruction register access, data register scan, and IDCODE verification-enabling production test coverage and field firmware updates.

How many multi-gigabit transceivers does XC4VLX40-10FFG1148I include?

XC4VLX40-10FFG1148I integrates sixteen 2.5 Gbps multi-gigabit transceivers. Each lane supports 8B/10B encoding, elastic buffers, and programmable pre-emphasis-making it suitable for CPRI, Serial RapidIO, and Gigabit Ethernet physical layer interfacing.

Is XC4VLX40-10FFG1148I RoHS compliant?

Yes, XC4VLX40-10FFG1148I is RoHS-compliant and manufactured with Pb-free solder balls in its FFG1148 package. Full compliance documentation-including substance declarations and test reports-is available through AMD's Product Change Notification (PCN) archive.
