XC2V40-4FGG256I

The XC2V40-4FGG256I is a Virtex®-II series FPGA offered in a 256-ball fine-pitch BGA (17 × 17 mm) surface-mount package. This device delivers 40,000 system gates, 576 logic elements, approximately 0.074 Mbits of embedded RAM (73,728 bits), and 88 user I/Os, making it suitable for moderate-density programmable logic tasks in industrial environments.

Built on the Virtex-II platform architecture, the device benefits from the platform’s memory hierarchy, arithmetic primitives and clocking features described in the Virtex-II family documentation, while providing a compact package, RoHS compliance, and an industrial-grade operating range.

Key Features

• Core Logic – 40,000 system gates and 576 logic elements (cells) for combinational and sequential logic implementation.
• Embedded Memory – 73,728 bits of on-chip RAM (approximately 0.074 Mbits) for block and distributed memory requirements.
• I/O Capability – 88 user I/Os to support diverse peripheral and external device interfacing.
• Package & Mounting – 256-ball fine-pitch BGA (256-FBGA, 17×17) in a surface-mount configuration for dense PCB layouts.
• Power – Core supply range specified at 1.425 V to 1.575 V for compatibility with low-voltage FPGA power domains.
• Temperature & Grade – Industrial-grade device specified for operation from −40 °C to 100 °C; RoHS compliant.
• Virtex-II Platform Capabilities (family-level) – The Virtex-II platform includes SelectRAM memory hierarchy, dedicated 18-bit × 18-bit multiplier blocks, Digital Clock Manager (DCM) circuitry and high-performance I/O features as documented in the Virtex-II family datasheet.

Typical Applications

• Industrial Control & Automation – Use the device’s industrial temperature range and flexible I/O to implement real-time control, sensor interfacing, and custom logic for factory automation.
• Embedded System Prototyping – Moderate-density logic and on-chip RAM make this FPGA suited for developing and validating embedded controllers and custom processing blocks.
• Communications Interfaces – 88 user I/Os support interface bridging and protocol translation tasks where programmable timing and logic are required.

Unique Advantages

• Balanced Logic Density: 40,000 gates and 576 logic elements provide a mid-range capacity for designs that require more than small CPLDs but less than high-density FPGAs.
• Compact BGA Packaging: The 256-FBGA (17×17) package supports space-constrained PCB designs while retaining substantial I/O and logic resources.
• Industrial Temperature Range: Specified operation from −40 °C to 100 °C enables deployment in harsher environments where extended temperature tolerance is required.
• Low-Voltage Core: A defined core supply range (1.425 V to 1.575 V) accommodates low-voltage power architectures common in modern systems.
• On-Chip Memory Resource: Approximately 0.074 Mbits of embedded RAM provides immediate local storage for buffers, FIFOs, and small data structures without external memory.
• Standards-Based Platform Features: Built on the Virtex-II platform, the device benefits from documented family-level primitives such as dedicated multipliers and clock management blocks for common digital signal and timing tasks.
