XC4VLX25-10FF668I

The XC4VLX25-10FF668I is a Virtex-4 LX field programmable gate array (FPGA) from AMD offered in a 668-FCBGA (27×27) surface-mount package. Designed for industrial-grade use, it provides a balance of reconfigurable logic capacity, on-chip memory, and a high I/O count for systems that require flexible hardware implementation within a well-defined voltage and temperature envelope.

Its combination of logic resources, embedded RAM, and 448 I/O pins makes it suitable for applications that need consolidated interfaces and significant on-chip programmable logic while operating across a wide industrial temperature range.

Key Features

• Core logic — 2,688 logic blocks and 24,192 logic elements provide sizable reconfigurable logic capacity for custom digital functions and hardware acceleration.
• Embedded memory — Approximately 1.33 Mbits of on-chip RAM (1,327,104 bits) for data buffering, state storage, and local memory needs.
• I/O capacity — 448 user I/O pins to support multiple interfaces and parallel connections without extensive external buffering.
• Package & mounting — 668-BBGA / 668-FCBGA (27×27) package in a surface-mount form factor for compact, board-level integration.
• Power — Core supply voltage range of 1.14 V to 1.26 V to match system power domains and regulator designs.
• Industrial temperature range — Rated for operation from −40°C to 100°C for robust operation in temperature-varied environments.
• Regulatory status — RoHS compliant for environmental and materials compatibility.

Typical Applications

• Industrial control and automation — Implement custom control logic, protocol conversion, and interface consolidation using programmable logic and ample I/O.
• Embedded systems — Integrate on-chip RAM and logic elements to offload or accelerate functions within compact, surface-mount designs.
• High-density I/O systems — Support multiple parallel interfaces or bus connections with the FPGA’s 448 I/O pins to minimize external components.

Unique Advantages

• High logic capacity: 24,192 logic elements enable complex state machines, custom datapaths, and substantial combinational/sequential logic integration on-chip.
• Significant embedded memory: Approximately 1.33 Mbits of RAM reduces dependence on external memory for buffering and local storage.
• Large I/O count: 448 I/O pins facilitate direct connection to sensors, actuators, and parallel interfaces, reducing system-level routing complexity.
• Industrial robustness: Specified operating range from −40°C to 100°C supports deployment in temperature-challenging environments.
• Compact board-level footprint: 668-FCBGA (27×27) surface-mount package enables dense PCB integration while maintaining thermal and electrical connectivity.
• Controlled core power range: 1.14 V to 1.26 V supply requirement aligns with common FPGA power architectures for straightforward power design.
