AMD XC4VLX40-10FFG1148C

Overview

XC4VLX40-10FFG1148C from AMD (formerly Xilinx) is a Virtex-4 LX family FPGA with 41,472 logic cells, 2.5 Gbps multi-gigabit transceivers, and embedded PowerPC 405 cores. It features 2,016 Kbits of block RAM, 128 DSP48 slices, and operates at -10 speed grade (1.0 ns CLB delay). It is used in high-performance digital signal processing and reconfigurable computing systems.

For engineers reviewing the XC4VLX40-10FFG1148C datasheet, pinout, applications, or equivalent options, key considerations include I/O voltage compatibility (1.2 V/1.5 V/1.8 V/2.5 V), thermal management for 1148-pin flip-chip BGA, transceiver reference clock requirements, and configuration mode selection (Master SelectMAP, Slave Serial).

Technical Context

The XC4VLX40-10FFG1148C implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), distributed RAM, and dedicated routing resources. It supports multiple configuration modes including JTAG, Master SelectMAP, and Slave Serial, with configuration bitstream security via AES encryption.

It integrates 16 RocketIO™ multi-gigabit transceivers supporting protocols including PCI Express Gen1, Serial RapidIO, and Gigabit Ethernet. The embedded PowerPC 405 RISC processor core enables system-on-chip integration for control-plane functions alongside programmable logic.

FAQ

What is the maximum supported I/O standard voltage for XC4VLX40-10FFG1148C?

XC4VLX40-10FFG1148C supports I/O voltages of 1.2 V, 1.5 V, 1.8 V, and 2.5 V per bank, with bank-specific VCCO settings. Each I/O bank must be configured with a single VCCO voltage, and differential standards like LVDS require matching VRP/VRN reference voltages. This flexibility allows mixed-interface designs without external level shifters.

Does XC4VLX40-10FFG1148C include on-chip configuration memory?

No, XC4VLX40-10FFG1148C does not include on-chip non-volatile configuration memory. It relies on external configuration devices such as SPI serial PROMs or parallel NOR flash. Configuration occurs at power-up via Master SelectMAP, Slave Serial, or JTAG modes, and the bitstream is loaded into volatile SRAM-based configuration memory.

Can XC4VLX40-10FFG1148C operate in industrial temperature range?

Yes, the 'C' suffix in XC4VLX40-10FFG1148C denotes commercial temperature grade (0 °C to 85 °C ambient). For industrial operation (–40 °C to +100 °C), the equivalent part is XC4VLX40-10FFG1148I, which uses the same package and pinout but is screened and characterized for extended thermal performance.

How many RocketIO transceivers are integrated in XC4VLX40-10FFG1148C?

XC4VLX40-10FFG1148C integrates 16 RocketIO multi-gigabit transceivers. Each supports data rates from 622 Mbps to 2.5 Gbps, includes built-in 8B/10B encoding/decoding, and can be configured for protocols including PCI Express Gen1, Serial RapidIO, and Gigabit Ethernet. All transceivers share common reference clock inputs and PLL resources.

Is XC4VLX40-10FFG1148C compatible with Xilinx ISE 14.7 design tools?

Yes, XC4VLX40-10FFG1148C is fully supported in Xilinx ISE Design Suite 14.7, including synthesis, place-and-route, timing analysis, and bitstream generation. It is not supported in Vivado, as Virtex-4 devices were retired prior to Vivado's introduction. Legacy ISE toolchain remains the official and only validated flow for this device.
