XC4VSX35-11FF668I

The XC4VSX35-11FF668I is a Virtex®-4 SX series FPGA from AMD provided in a 668-FCBGA (27×27) surface-mount package. It integrates a substantial logic fabric, on-chip memory and a high I/O count for designs that require flexible, reprogrammable digital logic with industrial-grade temperature capability.

With 34,560 logic elements, approximately 3.54 Mbits of embedded memory and 448 I/O, this device is oriented toward applications that need significant logic capacity, local RAM and broad external interfacing within a compact BGA package.

Key Features

• Logic Capacity  34,560 logic elements organized across 3,840 logic blocks, enabling complex combinational and sequential implementations without external logic.
• Embedded Memory  Approximately 3.54 Mbits of on-chip RAM for buffering, on-chip data storage and low-latency processing.
• I/O Density  448 dedicated I/O pins to support wide parallel buses, multiple serial interfaces or mixed-signal front ends via external transceivers.
• Power Supply Range  Operates from 1.14 V to 1.26 V, suitable for systems designed around the specified core voltage range.
• Industrial Temperature Range  Rated for operation from −40 °C to 100 °C and marked as Industrial grade for deployment in temperature-demanding environments.
• Package and Mounting  668-FCBGA (27×27) surface-mount package provides a compact footprint with high-pin-count routing capability for dense system boards.
• RoHS Compliant  Manufactured in accordance with RoHS requirements.

Typical Applications

• Industrial Control  Implements motor control, PLC logic and real-time I/O aggregation leveraging the industrial temperature rating and high I/O count.
• Data Processing  On-chip memory and large logic capacity support packet processing, signal aggregation and deterministic data-path functions.
• High-Density I/O Systems  Provides the pin count and logic resources needed for board-level aggregation of sensors, converters and parallel interfaces.

Unique Advantages

• Substantial Logic Resources: 34,560 logic elements allow implementation of sizeable custom logic and control state machines on a single device.
• Significant On-Chip RAM: Approximately 3.54 Mbits of embedded memory reduces reliance on external RAM for buffering and local data storage, simplifying board-level design.
• High I/O Count: 448 I/O pins enable direct interfacing to numerous peripherals and wide buses without extra interface chips.
• Industrial Thermal Capability: −40 °C to 100 °C rating supports deployment in temperature-challenging environments common in industrial systems.
• Compact High-Pin Package: 668-FCBGA (27×27) delivers high integration density suitable for space-constrained, high-functionality boards.
• Standards-Compliant Manufacturing: RoHS compliance aligns with environmental and regulatory requirements for lead-free production.
